David Suddjian Capitola [Non-text portions of this message have been removed] Subject: Swainson's Hawk over Burlingame From: Tronthorn AT aol.com Date: Tue, 16 Mar 2010 21:42:29 EDT At ( 4:30 ) this afternoon while driving back from San Francisco along Highway 101 in Burlingame, I notice a raptor soaring over the highway just south of the Broadway exit. I rarely do see a Red-tailed Hawk at this location and I decided to give it my extra attention. It paid off as the raptor was an adult dark morph SWAINSON'S HAWK. I was able to observed the Swainson's Hawk as it circle twice overhead. Swainson's Hawk is a rare migrant through San Mateo County in the spring. This is the first dark morph I have seen in the spring with all others that were light morphs. Could this individual be the same one reported this morning from Menlo Park? At Coyote Point today, there was an early morning flight of migrants overhead. ( 1 ) Merlin ( 1 ) Barn Swallow ( 11 ) American Robins in a group ( 59 ) Cedar Waxwings ( 3 ) American Pipits together, the first time I have had this species migrating at Coyote Point in the spring ( 3 ) Red-winged Blackbirds ( 1 ) Brewer's Blackbird ( 83 ) Lesser Goldfinches The ( 6 ) Greater White-fronted Geese were seen today in the field near the Coyote Point Yacht Club. Ron Thorn Subject: Swainson's Hawk over Menlo Park From: "verdoesm" <verdoesm AT yahoo.com> Date: Tue, 16 Mar 2010 21:20:01 -0000 This morning (~9.20am) I saw a dark morph Swainson's Hawk soaring over Menlo Park. Good birding! Martijn Verdoes Menlo Park Subject: Gazos From: Al Eisner <eisner AT SLAC.Stanford.EDU> Date: Tue, 16 Mar 2010 14:09:22 -0700 (PDT) I had a little time for a coastal visit this morning. Unfortunately, a low bank of haze or fog made for minimal visibility at Pigeon Point, so I went instead to Gazos Creek. As Dan noted, singing Orange-crowned Warblers are out in force. Within just 0.1 miles of the pumphouse, I heard five (and saw some of them). Also here I heard my first-of-the-year singing Wilson's Warbler (just one). No other new arrivals, but some of the wintering Ruby-crowned Kinglets are now singing. (The first one I heard today baffled me for a moment, something which seems to happen each year!) Other spots turned up more Orange-crowns, but nothing new. I did try for the Flycatcher at Water Lane, but no luck. And today the Kites there were only harrassing Ravens, so all-in-all less interesting than Ron's recent visit there! More Orange-crowned Warblers, of course. Al Eisner Subject: He's BAACKK! Indigo in San Bruno returns From: "Eddie Bartley" <eddie AT naturetrip.com> Date: Mon, 15 Mar 2010 20:08:36 -0700 Just received a note and photo from Ann Parker that (the same?) Indigo Bunting returned to her feeder on March 14 and this time he has almost an entirely new set of brilliant blue duds. Added the photo to this page link. http://www.naturetrip.com/INBUm1wSanBruno21310.html Big thanx to Ann for sharing her neat sighting! Eddie Bartley www.naturetrip.com [Non-text portions of this message have been removed] Subject: Pillar Pt. by Kayak From: Barbara Kossy <bkossy AT coastside.net> Date: Mon, 15 Mar 2010 18:09:56 -0700 I was able to get out for a bit of paddling around noon. The harbor was still full of loons. I saw at least 4 each of Pacific and Red Throated Loons in changing plumage. Shorebirds on the westernmost breakwater included a Surfbird, 5 Black Oystercatchers, Whimbrels, Black Turnstones, Sanderlings, and Marbled Godwits. Lots of grebes were in the water of the harbor. At least a few Eared Grebes have "pointier" heads. Western Grebes were present in good numbers too. I've been looking for a Clarks Grebe for a while, but haven't seen one. None spotted today. There were lots of Surf Scoters in the harbor. Other ducks in the harbor included a few Common Goldeneye, and Buffelhead. Outside of the harbor was a flock of about 50 Surf Scoters just outside the south breakwater. And near the south end of the western breakwater, just about 1/4 mile out, I saw the first Common Murre I've seen in a long time. A bit later I spotted a single harbor porpoise. Barbara Moss Beach Subject: bayside notes From: Tronthorn AT aol.com Date: Mon, 15 Mar 2010 20:30:20 EDT This afternoon, I stopped at the waterbird ponds along Radio Road in Redwood Shores. A Black Skimmer was preening among ducks and shorebirds on the long island. Today's Black Skimmer is the first to return to Redwood Shores this spring. Also at Redwood Shores, the male EURASIAN TEAL was still present on the pond behind the Nob Hill Market in Redwood Shores. Last week I did a couple of visits to Coyote Point, when the weather was clear. Birds moving through were a male Cinnamon Teal in the freshwater marsh. Flyovers were Tree and Violet-green Swallows, Cedar Waxwings, Brown-headed Cowbirds ( first arrival ), Lesser Goldfinches and an uncommon migrant at Coyote Point Purple Finches. Drop-ins were a Red-breasted Sapsucker, first Orange-crowned Warbler and Fox Sparrow. On March 8, the ( 6 ) Greater White-fronted Geese were still present. Band-tailed Pigeons are regular visitors to the shoreline at this time of the year. ( 40 ) Band-tailed Pigeons were a high count at Coyote Point There have been up to ( 8 ) adult Brown Pelicans still lingering at Coyote Point and obviously are not returning to the breeding grounds. The rest of the week should be favorable for migrants moving through Coyote Point with high pressure system building in. Ron Thorn Subject: Prius vs. Wild Turkey, 3/10/2010 From: "Garth Harwood" <gharwood AT hiddenvilla.org> Date: Mon, 15 Mar 2010 17:14:22 -0700 Hi All, Chris Macintosh's mention of turkeys at Windy Hill over the weekend reminded me to post that last Weds. 3/10/10, on my way home along Alpine Rd. and deep into the redwood forest near the Heritage Grove, a tom turkey stood in the middle of that skinny road and stared down my Prius at about 5:45PM. Apparently alone, he stood his ground and puffed up to his maximum air pressure until I came to a complete stop. Then - presumably seeing his own reflection in the shiny black paint - he attacked. It wasn't much of a fight. Pecking the car was clearly unsatisfying and he gave that up quickly, preferring instead to shake his feathers and take stiff steps back and forth in front of the car, calling and making various small, whining noises. Then, just for fun and because there was no other traffic on this back road, I dropped my window a couple of inches and called back to him. That did it! He stepped around to my driver-side door and stared at me eye to eye from about 12 inches, calling much more excitedly. The look in his eye was one of ferocious determination which had no room for fear. He was tall enough that I didn't have to look down more than a couple of inches into his eyes, and I was glad to have that shatterproof glass between us! I had the distinct impression that if the window had been fully open, he'd have come right through it. As it was, he settled for the standoff and we exchanged calls and stares for a couple more minutes. I tried to pull forward then, but that set him off again. My front tire, being the part that moved most obviously, got pecked repeatedly every time I inched forward. He didn't mind pecking the rubber at all. I would've kept on anyway, and gotten out of there, except for worrying that his head would get jammed in the wheel well if I did. Finally, another car passed (with a long sidewise look) and I was able to take advantage of his distraction and slip away too. In my rearview he was strutting back and forth, in complete domination of the battleground. I kind of hope there was a hen somewhere nearby to be impressed by all that effort! The next day at work, one of my colleagues from back east said that he'd had car/bird encounters like that back home. I sure hadn't. It would've been pretty exciting to be on a bicycle or afoot for that experience! Good birding, Garth Harwood Pescadero [Non-text portions of this message have been removed] Subject: Violet Green Swallows From: MELISSA HERO <mdhero AT sbcglobal.net> Date: Mon, 15 Mar 2010 08:54:09 -0700 (PDT) The swallows are back this morning at Carlmont High School in Belmont.  They nest in T Hall each year. Melissa Hero Belmont, CA Subject: Menlo Park: bald eagle From: Chris MacIntosh <cmaci AT sbcglobal.net> Date: Sun, 14 Mar 2010 19:49:46 -0700 (PDT) What a great weekend.It seems not just we humans were getting out and about. Driving up Sand Hill Rd around 4 pm today, a large raptor was flying over I-280, which I expected to turn into a red-tailed hawk - until it showed a solidly white tail. Luckily there was a bike lane to pull over into so I could get a good look at it. It soared higher and went over towards the Jasper Ridge side. This is my first Bald Eagle sighting on the peninsula. Later on, there was a small flock of Wild Turkey in the open grassland halfway up Windy Hill.

The males were putting on quite a courtship display including vocalization with a frog-like sound. There was also a raft of 12 RING-NECKED DUCKS. Two PHAINOPEPLAS landed in a tall tree on the south side of the pond and were squawking loudly. At the same time a male BELTED KINGFISHER was chattering on the west end of the pond. It was quite a vocal ensemble of birds. On Thursday we went to Pillar Point and saw several COMMON LOONS and RED-THROATED LOONS with one of each in transition to alternate plumage. There were more than 10 COMMON GOLDENEYE, all female or immature males, near the Pier and a PELAGIC CORMORANT as well. A flock of 7 BRANT landed in the pond at the west end of the harbor and there were 3 RED-BREASTED MERGANSERS (2 male) inside the harbor.

Pigeon Point Time ( 07:00-10:00 ) Visibility sky clear, haze at the horizon, wind northwest ( 7-10 ) knots Swells ( 12-14 ) feet Compared to last week, there were no Brant. The number of Surf Scoters and gulls were low. Herring Gull was the most numerous. Red-throated Loon ( basic plumage 30, alternate plumage 1, north, the first in alternate plumage to be seen this spring ) Common Loon ( basic plumage 2 north ) Western Grebe ( 6 on the water ) MANX SHEARWATER ( 1 seen around 08:00 flying north about half way out to the horizon. Quick wingbeats, short glide, hugging the ocean surface. Small black and white tubenose. Shape cruciform, short tail. Upperparts black. Underparts brilliant white, no dusky smudging on sides, white extending up as a short spur behind the ear coverts, undertail coverts white extending to the end of the tail. Underwings brilliant white. I have seen a few in the spring from Pigeon Point. Today's date would be the earliest I have seen in the spring ) Brown Pelican ( 8 adults south ) Double-crested Cormorant ( 1 adult north ) Brandt's Cormorant ( 4 north ) Pelagic Cormorant ( 17 north ) White-winged Scoter ( 1 north, 2 on the water ) Surf Scoter ( 140 north ) Red-breasted Merganser ( 5 north ) Western Sandpiper ( 6 together north, first migrants seen this spring ) Mew Gull ( 10 north, 8 were adults ) California Gull ( 57 north, 53 were adults ) Herring Gull ( 179 north, 162 were adults ) Thayer's Gull ( 3 adults north ) Glaucous-winged Gull ( 6 north, 5 were adults ) Western Gull ( 54 north, 46 were adults ) BLACK-LEGGED KITTIWAKE ( 2 adults north ) Common Murre ( 18 south ) Late morning we stopped off at the end of Water Lane in the town of Pescadero. We parked at the rangers station and walked the trail next to the Monterey Pines. Between the Monterey Pines and Pescadero Creek, we observed the HAMMOND'S FLYCATCHER Dominic Mosur found on January 2 during the Ano Nuevo Christmas Bird Count. As far as I know the Hammond's Flycatcher has not been seen since January 2. We watched the Hammond's Flycatcher fly out of the field of Coyote Brush into the Monterey Pines where it forage. We had expected the Hammond's Flycatcher to have wintered at the location and did look for it a few times with no success. A surprise was a Barn Owl on the ground next to one of the buildings. The Barn Owl flew up into the Monterey Pines, where it was harass by White-tailed Kites building a nest. The Barn Owl was calling from the pines and eventually flew off to the riparian corridor. A couple of Rough-winged Swallows the first we had seen this spring were flying towards the marsh. At Water Lane and Pescadero Road, there were at least ( 5 ) Tree Swallows and ( 2 ) Barn Swallows in the field on the south side of Pescadero Road. High in the sky were ( 3 ) White-throated Swifts with many swallows. It is the first time I have seen White-throated Swifts in the town of Pescadero. At Pescadero Beach, a migrant group of ( 6 ) Snowy Egrets flew into the marsh.

After some follow-up and analysis of some pictures I reviewed, it turns out the hawk was a very light juvenile RED-TAILED HAWK. From a distance, the body and face were very white, and as originally reported, the bird was soaking wet due to heavy rain and its exposed perch on a telephone pole. The pictures reveal slight patagial markings on the leading edge of the underwing that would not be expected for a Ferruginous Hawk. In the field, the upper wing seemed to have a rufous shoulder patch and white windows on the outer wing. By zooming in on the pictures, I was able to correctly identify this bird as a Red-tailed Hawk. I saw the bird fly about 150 yards away to land on a Coyote Bush, and from there the bird looked very white. As I walked closer, it flew back to a large pine near the highway, again giving me the impression of more Ferruginous behavior rather than a Red-tail. I never saw this bird fly more than 15 feet above the ground on both direct flights between perches. Pictures can be seen at the following link: http://www.flickr. com/photos/12329229 AT N03/4424430930/in/photostream/> com/photos/12329229 AT N03/4424430930/in/photostream/ Zoom in for better looks at the field marks. This means there is still an opportunity to find a wayward Ferruginous Hawk to add to the County list for 2010.

The pictures reveal slight patagial markings on the leading edge of the underwing that would not be expected for a Ferruginous Hawk. In the field, the upper wing seemed to have a rufous shoulder patch and white windows on the outer wing. By zooming in on the pictures, I was able to correctly identify this bird as a Red-tailed Hawk. I saw the bird fly about 150 yards away to land on a Coyote Bush, and from there the bird looked very white. As I walked closer, it flew back to a large pine near the highway, again giving me the impression of more Ferruginous behavior rather than a Red-tail. I never saw this bird fly more than 15 feet above the ground on both direct flights between perches.

This means there is still an opportunity to find a wayward Ferruginous Hawk to add to the County list for 2010.

George Chrisman Burlingame, CA Subject: February Recap From: George Chrisman <geodani55 AT yahoo.com> Date: Fri, 12 Mar 2010 08:23:47 -0800 (PST) February 2010 February 2010 proved to be a relatively quite month for new birds in San Mateo County with only five species added to the January list. The January was revised to delete the Swainson’s Hawk reported for the Ano Nuevo CBC. This bird was actually a count week bird seen on 12/31/09 and not during the count itself. Another correction was the omission of RED-BREASTED NUTHATCHES seen at Portola State Park by David Suddjian on January 16 . As a result, January ended with a total of 207 species. February added only 5 new birds for the month. No new birds with a rarity code of 5 or 6 were added. New sightings include a RED-NAPED SAPSUCKER reported by Andrew Olsen in Foster City along the Marina Lagoon on 2/6/10. This bird was not refound. Another one day wonder was the appearance of a juvenile male INDIGO BUNTING that was photographed at a backyard feeder in San Bruno on 2/13/10 by Ann Parker and reported by Eddie Bartley. And finally, a first cycle GLAUCOUS GULL was reported and photographed by Dan Singer on 2/20/10 in Pillar Point Harbor at Denniston Creek, as well as an additional first cycle GLAUCOUS GULL seen on 2/26/10 at San Pedro Creek in Pacifica. A BLACK-THROATED GRAY WARBLER was found in San Carlos by Peter Metropolis on February 10 and the first arrival of VIOLET-GREEN SWALLOWS were seen at Crystal Springs Reservoir on 2/19/10. This brings our total for the year to 212, which is still below our January 2009. Things should pick up with the arrival of new migrants in March, but we are still waiting for several expected species to appear. March arrivals include White-throated Swifts, most Swallow species, and the expected migrant warblers and vireos. If you have seen any birds not listed on the February list, please email me at Geodani55 AT yahoo.com. I will look forward to hearing about all of your new sightings and encourage you to post all notable sightings to http://groups.yahoo.com/group/peninsula-birding/ or www.eBird.org. The complete list of year to date birds will be posted on the Sequoia Audubon website in a couple of days. I'll keep you posted. Good Birding, George Chrisman Subject: Coastside From: "Dan Singer" <dsg2 AT sbcglobal.net> Date: Thu, 11 Mar 2010 15:31:25 -0800 I spent the morning wandering down the coast, enjoying the spectacular weather. Singing ORANGE-CROWNED WARBLERS were present in good numbers in appropriate habitat along Tunitas Creek, Pescadero, Cloverdale and Gazos Creek roads. The two HOODED MERGANSERS (male and female) were still in Gazos Creek, visible from the road about 75m east of Cloverdale Road. These are presumably the same ones seen on the 7th by Jim Yurchenko, Cassidy Ruge and Whitney Mortimer. I saw a single male BLUE-WINGED TEAL on the north pond at Pescadero Marsh on my way north while driving by at 60mph. The scoter flock visible from the cliffs north of Pescadero Beach contained 32 WHITE-WINGEDS, 15 BLACKS, and 27 SURFS. My first of spring BARN SWALLOW was flying around the Ritz Carlton at the south end of Half Moon Bay, but I failed to see the moorhen.

It seems to me that Barrow's used to be easy to see at Forster City for example. I remember days where it wasn't hard to see a dozen without too much effort at places like Leo Ryan Park. Now is it just me that had luck a few years ago, or have they declined quite a bit according to your records? I have not seen one for a while now!

Ron Thorn Subject: Weekend birds on the coastside From: "Garth Harwood" <gharwood AT hiddenvilla.org> Date: Tue, 9 Mar 2010 14:50:46 -0800 Hello All, On Saturday 3/6/2010 a threesome of Violet-green Swallows was vocal in the morning at our Pescadero orchard, 6 miles inland. Three Common Mergansers flew upstream also. Orange-crowned Warbler song along Pescadero Creek was the first I'd heard this spring. On Sunday 3/7 I checked in with Ron and Leonie at Pigeon Pt but as usual, found only a fraction of their goodies when I took up my own station on the point. The fact that I was only there for 45 minutes has only a little to do with that...anyway my best observations there were a flight of 160 northbound Brant, and a couple of resplendent male Red-breasted Mergansers. A bit to the south I stopped in at Gazos Beach. Wave action has reshaped that beach significantly, cutting deep into the dunes south of Gazos Creek, and there was no sign of any Snowy Plovers. A first-cycle Glaucous Gull did a slow glide past me just a few feet above the beach, but did not join the gulls standing at the creek mouth - perhaps it was the same one seen at Pigeon Point by Ron and Leonie. There was a flock of nearly 200 Sanderling hard at work, perforating the sand at the water's edge. Back home in the afternoon, a neighborhood first took place when a Eurasian Collared-dove began calling form a neighbor's yard. It was only a matter of time! A Red-breasted Sapsucker lingers in our orchard as well. --Garth Harwood Pescadero [Non-text portions of this message have been removed] Subject: Northern Rough-winged Swallow @ Canana Rd 3/9/10 From: "George Chrisman" <geodani55 AT yahoo.com> Date: Tue, 09 Mar 2010 22:05:55 -0000 This morning along Canada Road AT Edgewood Road, there was a single NORTHERN ROUGH-WINGED SWALLOW perched on the power lines along with 3 WESTERN BLUEBIRDS.

Cassidy Ruge Whitney Mortimer James Yurchenco Subject: rare bird report: 2 Northern Goshawks Feb 18, 2010, Santa Clara Co. From: Dave Helzer <davehelzerian AT gmail.com> Date: Sun, 7 Mar 2010 13:41:15 -0800 Hi All: my formal, full report on the 2/18/10 goshawks at Hidden Villa follows: RARE BIRD REPORT Based on Oregon Bird Records Committee Template Report Date: February 25, 2010 (submitted March 7, 2010) Observer: Dave Helzer, Portland, Oregon, davehelzerian AT gmail.com Observation: 2 Northern Goshawks (Accipiter gentiles) Date: February 18, 2010 at 1230 pm LOCATION: Hidden Villa, Santa Clara County, CA. Up Moody Road, about 2.5 miles west of 280, which is west of Los Altos. The site is a valley in the eastern foothills of the Santa Cruz Mountains, which are primarily in San Mateo County. The birds were observed from the north end of the main large parking lot for the Hidden Villa education center. DETAILS: Conditions were mild temperature, little wind, and slight overcast skies. The first bird was seen soaring low over the trees on the west side of the valley, after watching the first bird for a while, the second bird was seen at a much higher altitude. FIRST BIRD: I first saw the bird naked eye at a distance of about 200-300 feet; it was slowly soaring and circling about 100 feet above the canopy on the north side of the valley. My first impression was an intermediate to large sized hawk. At first I assumed it was one of the local Red-shouldered Hawks. A pair was very active in the area and I had been hearing and seeing both adults, moving around from tree to tree on both sides of the valley. I had also been seeing many Red-shouldereds over the last couple days in Sonoma and Marin Counties. Once I glassed the bird I immediately realized it was an accipiter based on diagnostic shape of the wings and tail, being shorter winged and longer tailed than a buteo. Field Marks observed: the underside of the bird was mostly uniform light gray with little contrast, the overcast conditions did not provide a lot of direct light on the undersides. The bird had the classic goshawk flight profile of proportionately longer wings than a Coopers and a broad tail with wedge shaped tip. It was very steady on the wing. It presented a heaved-bodied look and a very large, wide head that projected well beyond the wings, somewhat “bull-headed”. There was also a slight contrast that made the head appear a tad darker, especially the dorsal portion of the head, a vague cap of sorts. As the bird gained altitude I focused on the leading edge of the wings and noted the slightly more forward wrist than Coopers, the slightly more tapered wingtips than Coopers, and the proportionately larger, wider head than Coopers. And as noted before, the proportionately longer wings than Coopers was a key field mark. Sharp-shinned was easily eliminated based on overall jizz. Red-shouldered hawk of any age was eliminated by lack of buteo flight profile (broader winged, shorter tailed), lack of any obvious coloration (adult), lack of crisp white tail bands (adult), and lack of translucent wing crescents (any age). The bird flapped very little; in fact I don’t think I saw it flap once. It soared on fixed wings and gained altitude slowly but steadily, moving east across the valley. It vocalized a number of times, a single note call, fairly deep, that I can best describe as “accipiter like”. Maybe a “bark” or “chuck”, but not the incessant screaming that adult goshawks make near nests or when trapped. It was a much softer call than that. Overall observation time was about 10 minutes, maybe a little longer. SECOND BIRD: I followed the first goshawk as it gained altitude and moved east. As I followed it to roughly 1000 feet I spotted as second bird in flight a few hundred feet higher. At first, I was unsure what I was seeing; my first impression was some large bird moving through at high altitude. But the wing beat made no sense to me. After a brief moment of observation I dropped it and went back to the first bird. After a few moments with the first bird I went back to second bird and realized it was another goshawk. I recognized the behavior as a flight display I had seen before. The bird was flying very slowly with exaggerated, slowed down wing strokes very high above, and then very low below the body. Almost like a short-eared owl, but much slower and more dramatic. This behavior is defined as “slow-flapping” by Wheeler in Raptors of Western North America. Because the bird was fully exposing its underwing to more direct light than the first bird, I was able to detect a uniform pattern on the undersides (wings and body) of the bird indicating a probable adult Goshawk (no streaking at all). At that distance, I could not discern the diagnostic barring pattern of an adult goshawk, but the light uniform pattern is what one would expect to see of the underside adult plumage at that distance. At this point both birds were still gaining altitude and moving into a portion of sky with glare making viewing more difficult and I ceased observation. I looked for them again a few minutes later and they were gone, I suspect they had moved east over the ridge. EXPERIENCE WITH NORTHERN GOSHAWKS I have observed this species many times across the western United States. About 20 observations on the wing and 15 in the hand. I also taught raptor identification classes for adults for six years for the Audubon Society of Portland (classroom and field time). These classes covered 18 diurnal species (including Goshawk) that occur in Oregon. I have observed thousands of both Sharp-shinned and Coopers Hawks while working at, or visiting, hawk migration sites and in other habitats across the western US. Details of field experience with Goshawks follows with location and context (1995 to present): Goshutes Mountains, NV: 2-3 birds observed at this migration study while visiting as a raptor bander in training. Several years later observed about 5-6 birds on migration while leading a 5-day birding tour to this raptor migration site. Observations included opportunities to study Sharp-shinned, Cooper’s, and Goshawks flying together. 1 or 2 birds observed in the hand. Manzanos Mountains, NM: I trapped, banded and released 1 adult while working as full time raptor trapper at this migration site. Lowland Valleys of western Oregon: 2 wintering birds observed (one near Salem and one near Portland) Ochoco Mountains, OR: 1 adult observed in breeding season. Bonney Butte Raptor Migrations Site, Mt Hood, OR: 8-10 migrants observed on the wing, mix of ages. Approx 10-12 birds observed in the hand then released. “Slow-flapping” display flight (described above) observed at this site in the fall. All observations were over the course of about 10 migration seasons. Conboy National Wildlife Refuge, near Glenwood WA, lower east slope of Mount Adams: 1 adult observed in breeding season. FIELD GUIDES AND OPTICS USED: The birds were observed with 10x42 Swarovski binoculars. No field guides were consulted to identify the birds; I relied on past experience to recognize them. Raptors of Western North America by Wheeler was consulted to clarify terms for courtship flight observed. SIGNIFICANCE & INTERPRETATION: As a birder I am aware of the rarity of this observation in this part of California, with the species’ accidental or vagrant status. As a biologist I am keenly aware of the potential implication of breeding, or attempted breeding, by a species in decline well outside known areas of regular occurrence. While the slow-flapping behavior is typically a courtship flight, I am aware from observations in Oregon and from conversations with highly experienced hawk watchers that resident Goshawks will use this display in response to migrants moving through their territory. In other words, I think there are a couple possible interpretations of the behavior. One is the birds were a pair. The other is the one bird was territorial and the other was a passing migrant. Of course, they could also have both been migrants. ADDITIONAL NOTE: Alice Froehlich, an intermediate birder, had another independent observation during the same general period of time (shortly before my observation). While on a guided walking tour of the Hidden Villa site, Alice observed a large raptor with white-ish, or light gray, undersides flying just above the canopy south of my location. Her observation was naked eye and her impression was a large falcon or accipiter. While this observation was not diagnostic, I consider this an interesting tidbit of information to share. Please feel free to contact me with questions or to provide more information. Thank You. Dave Helzer Portland, Oregon ------------------------------------ Yahoo!

During the week, I stopped off at the pond behind the Nob Hill Market in Redwood Shores. The young bachelor EURASIAN TEAL is looking sharp in it's new attire. This is the same individual Dave Weber saw today. The male intergrade/ hybrid Eurasian Teal x Green-winged was still present with his female companion. The female does show mostly white with just little buff wash on the greater covert bar. She could be an Eurasian Teal, but it is a tenuous distinction from Green-winged Teal.

On a six hour tour with a visiting Scottish birder yesterday we swung through northwest SF and then down to San Mateo County (Sweeny Ridge, Arastradero, Radio Rd.) observing lengthy territorial battles (i.e. Kites and Red-shoulder), much displaying (woodpeckers, hummers), pair bonding (waterfowl), nest sitting (i.e. Red-shoulder) and building (Towhees, Red-tails). Many birds were in full or near full song including OC Warblers, RC Kinglets and especially sparrows. Most of the nearly 100 species we observed were expected but was pleased to see two White-throated Swifts at the Arastradero Preserve in Palo Alto. Been a couple of months since I've seen swifts. Also at Arastradero on Monday morning 3/1/10 - high overcast and super birdy there - something very attractive about the ancient Oak studded ravine above the east side of the lake (Paseo del Roble trail) - in about 15 minutes I observed 26 species and counted approximately 200 individuals, mostly hummers, thrushes (~100 Robins), wrens, warblers but an especially large gathering of Flickers, two of which were Yellow-shafted. There was a constant flow of bathers to the seasonal creek but also a lot of posturing and chasing activity. Then as if someone blew the lunch whistle (or maybe a raptor entered the scene but I couldn't see one), they almost all began to leave flying toward the lake and within two minutes there were almost no birds in that same area. Mixed flocking behavior is endlessly fascinating! Yesterday, with afternoon sunshine, activity was much diminished but perfect weather for a hike. Happy Trails!

Also, the three Hooded Mergansers were in the sed pond for the Soil Farm as I drove by.

Tom Goodier Subject: more on Clapper Rails & Colma Creek Mouth/SamTrans From: "Laurie" <fair80 AT comcast.net> Date: Wed, 03 Mar 2010 04:45:40 -0000 We have these notes from two occasions two years ago. In January 2008, we were there during a very high tide event such as we experienced on Monday. The researchers were, if I remember correctly, from USGS. "1/21/08: SamTrans/Colma Creek Mouth, SSF. High tide (8.4'), 9:50-11:45 a.m. 5 Clapper Rails in San Bruno Creek Channel and Colma Creek Mouth, with tide so high the channels were one mass of water. All the Clappers we saw were in the process of being netted, for tracking purposes, by a group of five researchers with a boat, working along the east shore of Colma Creek: four of the birds were caught, and the other made its escape flying to the west side of SamTrans. 3/24/08: SamTrans/Colma Creek, SSF. Low-mid tide (0.2' to 7.1'), 7:30-11:30 a.m. 6 (2/4): along San Bruno Creek Channel, nice views, one had an antenna and silver band on the right leg (2/1); east side SamTrans Trail (1); & Bay Trail from west side of Colma Creek/channel (2). We talked to some of the researchers from 1/21/08; they had fitted nine Clapper Rails with antennas, and they were setting out to find them." On the San Mateo County Birding Guide website, the site writeup is mine, but the photos were taken in March 2009 by Joe Morlan and Sonny Mencher, showing the mixed cordgrass. On March 29, 2009, Jeff & I led an SFBBO walk at the same location, and our photos show the invasive cordgrass removed. We were shocked at the time. We last heard Clapper Rails on 10/19/08. On the SFBBO walk, Ginny Marshall thought she heard one. It is heartening that Ron & Leonie have seen rails there since. Perhaps, if the transmitters are still working (fat chance), we can find out where the rails have gone.

The California > Gulls in the bay were beautifully white, mostly adults. Last winter (a year ago) it was still possible to find numerous Clapper Rails along the shoreline (particularly on the SamTrans side) during the very high tides. This year I've checked once on that side and once (this past weekend) on the side near Utah St., and found no Clappers either time. Are the rails better at hiding this year? Have I simply had poor luck (or poor skill)? Or has there been an actual collapse in the Clapper Rail population in that area? I'm curious to hear if others have been finding Clappers there in some numbers this season. Thanks. By the way, one other species I've had a few of there this year (not on Laurie's list) has been Wilson's Snipe. Al Eisner Subject: Birding Class and Field Trip with Alvaro From: "birdersue" <birdersue AT earthlink.net> Date: Mon, 1 Mar 2010 21:30:03 -0800 All are invited to a free birding class sponsored by the Sequoia Audubon Society to be held at the San Mateo Garden Center, 605 Parkside Way, San Mateo. Birding Class: Waterfowl By Alvaro Jaramillo Thursday, March 11, 2010, 7:00pm We take it for granted, but San Mateo County is about as rich a place as anywhere for wintering waterfowl. We are at a prime site, a world class place for ducks and geese. This class will touch on what makes waterfowl odd and special as far as birds go. It will also detail some of the tougher identification problems in the group while dealing with aspects of their migration, foraging behavior and habitat needs. Some experienced birders may see ducks and geese as "dull", not so; these are among our most gorgeous, interesting and also puzzling birds. If you are a beginner, this class will get your on the right track, if you are advanced, it will hopefully re-kindle your interest in the waterfowl. Alvaro leads birding tours of California and South America for Field Guides and has authored two birding books: The Birds of Chile and New World Blackbirds: The Icterids as well as contributing both popular and scientific articles to various publications. He also wrote the icterid chapter in The Sibley Guide to Bird Life and Behavior. Also join us for a follow-up field trip for the birding class: Radio Road Ponds, Redwood Shores Saturday, March 13th, 2010, 9:00 AM Winter migrants, especially ducks, are in great abundance on these ponds at this time of year. Directions: From US 101, take exit 411 and go east on Redwood Shores Parkway for a few miles. Go past Shearwater Parkway, and look for the tall electrical towers just past a slough on your right. There is a sign there that says "SBSA 1400 Radio Road." Turn right at this sign; you are now on Radio Road. You come to a stop sign; in front of you are the ponds of Radio Road; to your right is the Dog Park; to your left is the left spur of Radio Road; if you take a right, you can reach the main parking for Radio Road (and South Bayside System Authority). Open to everyone with a $5.00 fee paid to the instructor.

Mary Subject: Gull flock From: Al Eisner <eisner AT SLAC.Stanford.EDU> Date: Mon, 1 Mar 2010 11:02:07 -0800 (PST) Yesterday (Feb. 28) I headed for Pillar Point Harbor to check for gulls, but at 9 AM the water level was already too high for there to be any habitat (e.g., at the mouth of Denniston Creek). Given those conditions it seemed like a good time to try Venice State Beach, and there at the south end (peretty well isolated by inlets) was a flock which grew to at least 800 Gulls. (Not quite the "old days", but good for this winter!) Nothing of great note in the flock, but: It mainly consisted of Western and Glaucous-winged Gulls (I noted a few hybrids), plust quite a few California Gulls. Compared to past years, the fraction of young birds among the Californias was appreciable -- maybe they had particularly good nesting success last year. There were a number of Herring Gulls, and I spotted one adult Thayer's Gull and one Mew Gull. Of possible interest was a pale Gull, with a body rather like a young Glaucous-winged (a bit on the small side), but a bill which in pattern and shape resembled Glaucous. However, the primaries had more gray shading than I'd expect for Glaucous, and there was none of the subtle markings or undertail-covert barring a Glaucous would have. I was wondering about a possible hybrid, but left it unidentified. (In past years, Dan Singer would have shown up to help out!)

Later in the day, at about 3 PM, I saw a similarly-plumaged gull(probably the same individual) bathing in a tide pool near South Point. On the way back home, I noticed that the trio of HOODED MERGANSERS are still on the pond at the Soil Farm across Highway One from Redondo Beach Road at the southern end of Half Moon Bay.

There was patchy fog and salt spray giving not the best viewing conditions during the first hour. There had been a north wind at ( 7 ) knots and the last hour the wind shifted to the northwest changing to good visibility out to the horizon. Swells were ( 12 ) feet. As expected at this time of the year, there is little noticeable migration, except for gulls and the number of Surf Scoters are picking up. Red-throated Loon ( 12 basic plumaged flying north and south, no migrant adults in alternate plumaged at this time ) Pacific Loon ( 1 alternate plumaged north, not expected at this date, as the earliest migrant adult in alternate plumage I have recorded was not until Mar. 19 ) Common Loon ( 2 basic plumaged on the water ) Brown Pelican ( 27 south, most were adults ) Double-crested Cormorant ( 2 north ) Pelagic Cormorant ( 28 north, earliest date for migrants Mar.1 ) Brandt's Cormorant ( 8 north ) Great Egret ( 1 north ) Brant ( 9 north ) Northern Pintail ( 1 male north ) Surf Scoter ( 147 north ) Black Oystercatcher ( 3 ) Surfbird ( 14 north, group of 12, earliest date for migrants Mar. 2 ) Sanderling ( 30 north, could be early migrants, earliest date for migrants Mar. 16 ) Heerman's Gull ( 1 alternate plumaged adult south, late migrant, latest record I have for an alternate plumaged adult is Mar. 2 ) Mew Gull ( 13 north, 5 were adults ) California Gull ( 120 north, 110 were adults ) Herring Gull ( 108 north, 102 were adults ) Thayer's Gull ( 2 adults north ) Western Gull ( 201 north, 183 were adults ) Glaucous-winged Gull ( 96 north, 59 were adults ) Glaucous-winged x Western Gull hybrid ( 2 adults north ) Common Murre ( 90 south ) Marbled Murrelet ( 2 south ) Rhinoceros Auklet ( group of 4 south ) Gray Whale ( 1 ) In the town of Pescadero, the flooded field on the south side of Pescadero Road just east of Bean Hollow Road had some ducks. ( 18 ) Cinnamon Teal were most likely migrants as the species becomes common as it passes through at this time of the year. A male Blue-winged Teal was present. Out of place in the shallow water was a male Common Goldeneye. Along Gazos Creek, we noticed a lone butterfly that got our attention and was a first ever sighting for us a Satyr Anglewing! Ron Thorn Leonie Batkin Subject: O'Connor Ponds, Ravenswood, and Southern Marshes 2/27/10 From: "George Chrisman" <geodani55 AT yahoo.com> Date: Sun, 28 Feb 2010 06:24:36 -0000 This morning I birded the southernmost end of the bayside marshes, starting at the end of O'Connor Street in East Palo Alto around 9:30 AM (2/27/10). High tide was around 11:00 AM plus the Tsunami surge predicted for 1:30 PM. No rails found here, but several CINNAMON TEAL, NORTHERN PINTAIL, and lots of dabbling and diving ducks. The cackle of at least one, maybe two male RING-NECKED PHEASANTS could be heard regularly. One Savannah Sparrow was seen, along with many SONG SPARROWS and COMMON YELLOWTHROATS. There were several groups of GREATER YELLOWLEGS, totaling over 20 birds. A mated pair of NORTHERN HARRIERS was exchanging a mouse and was active the entire time I was present. Around 11:00 AM I moved to Ravenswood Open Space Preserve at the end of Bay Road. There I found a SORA standing on the submerged PGE boardwalk, along with 2 male EURASIAN WIGEON, a SPOTTED SANDPIPER, and hundreds of GREATER SCAUP, CANVASBACKS, AMERICAN WIGEON, and GREEN-WINGED TEAL. There were also 2 BROWN PELICANS that were diving in the cove. Around noontime, I headed to the base of the Dumbarton Bridge, but it was too flooded for shorebirds and most ducks. There was a giant flock of over 1000 MARBLED GODWITS and 200 WILLETS that were roosted on a distant levee that flushed into the air for a moment, and then settled back down on the berm. I did not see the cause of the disturbance, but there has been a pair of PEREGRINE FALCONS present here on a regular basis. I just didn't see them today. There was a large group of 30-40 volunteers from the SFBBO, Cargill, and other volunteers spreading oyster shells in the newly restored salt ponds for Snowy Plover habitat improvement. At least half the group was made up of school aged kids, which was nice to see. At first I though it must be a Ducks Unlimited event, because everyone was wearing camo hats and even a few camo painted pick-up trucks and ATV's, but the hats were provided by Cargill. At Third Avenue Marsh near the Mariner's Point Golf Course in San Mateo, I found another EURASIAN WIGEON, a HORNED GREBE, an EARED GREBE, and a flock of 29 SNOWY EGRETS in the marsh. A BELTED KINGFISHER was perched on a wire above Bair Island as I drove north on 101. There was not a drop of rain all morning in this area. Good Birding, George Chrisman Burlingame, CA Subject: O'Connor Ponds, Ravenswood, and South County Marshes 2/27/10 From: "George Chrisman" <geodani55 AT yahoo.com> Date: Sun, 28 Feb 2010 06:44:16 -0000 This morning I birded the southernmost end of the bayside marshes, starting at the end of O'Connor Street in East Palo Alto around 9:30 AM (2/27/10). High tide was around 11:00 AM plus the Tsunami surge predicted for 1:30 PM. No rails found here, but several CINNAMON TEAL, NORTHERN PINTAIL, and lots of dabbling and diving ducks. The cackle of at least one, maybe two male RING-NECKED PHEASANTS could be heard regularly. One SAVANNAH SPARROW was seen, along with many SONG SPARROWS and COMMON YELLOWTHROATS. There were several groups of GREATER YELLOWLEGS, totaling over 20 birds. A mated pair of NORTHERN HARRIERS was exchanging a mouse and was active the entire time I was present. Around 11:00 AM I moved to Ravenswood Open Space Preserve at the end of Bay Road. There I found a SORA standing on the submerged PGE boardwalk, along with 2 male EURASIAN WIGEON, a SPOTTED SANDPIPER, and hundreds of GREATER SCAUP, CANVASBACKS, AMERICAN WIGEON, and GREEN-WINGED TEAL. There were also 2 BROWN PELICANS that were diving in the cove. Around noontime, I headed to the base of the Dumbarton Bridge, but it was too flooded for shorebirds and most ducks. There was a giant flock of over 1000 MARBLED GODWITS and 200 WILLETS that were roosted on a distant levee that flushed into the air for a moment, and then settled back down on the berm. I did not see the cause of the disturbance, but there has been a pair of PEREGRINE FALCONS present here on a regular basis. I just didn't see them today. There was a large group of 30-40 volunteers from the SFBBO, Cargill, and other volunteers spreading oyster shells in the newly restored salt ponds for Snowy Plover habitat improvement. At least half the group was made up of school aged kids, which was nice to see. At first I though it must be a Ducks Unlimited event, because everyone was wearing camo hats and even a few camo painted pick-up trucks and ATV's, but the hats were provided by Cargill. At Third Avenue Marsh near the Mariner's Point Golf Course in San Mateo, I found another EURASIAN WIGEON, a HORNED GREBE, an EARED GREBE, and a flock of 29 SNOWY EGRETS in the marsh. A BELTED KINGFISHER was perched on a wire above Bair Island as I drove north on 101. There was not a drop of rain all morning in this area. Good Birding, George Chrisman Burlingame, CA Subject: Princeton in the rain From: Matthew Dodder <mdodder AT sbcglobal.net> Date: Sat, 27 Feb 2010 16:48:56 -0800 All, I led my Palo Alto Adult School to Princeton Harbor despite the foul weather forecast. The news of the quake in Chile arrived too late to change our plans and the tsunami warnings at Maverick's caused a nearly complete change in plans once we'd all arrived. We were able to get brief looks at the harbor from the Maverick's Beach parking lot before we were asked to leave by rangers. Before leaving we found two dozen BRANT, as well as many more common water birds like BUFFLEHEAD, SURF SCOTER, WESTERN EARED and HORNED GREBE. COMMON LOON, BROWN PELICAN, WHIMBREL and SANDERLING. We also had EURASIAN COLLARED DOVE and TOWNSEND'S WARBLER in the cypress trees. Rain made birding very difficult here so we retreated to more sheltered areas. Pilarcitos Creek, behind Burger King produced a male MERLIN, several ALLEN'S HUMMINGBIRDS as well as at least two ORANGE-CROWNED WARBLERS and HUTTON'S VIREO. Also found were a pair of DOWNY WOODPECKERS, and several flyover BAND-TAILED PIGEONS. Skylawn Memorial Park produced 2-3 flyover RED CROSSBILL as well as the usual WESTERN BLUEBIRD, DARK-EYED JUNCO. . . .

I was delighted to observe the bird at eye-level as it took advantage of the strong southerly winds to cruise the shoreline in search of prey.

A new Pacifica bird for me! Joe Morlan joined me and got to see it as well before the gull flock was disturbed and the Glaucous took flight, heading northward. A little earlier in afternoon after the weather broke, I looked out my window and noticed a flock of twelve Greater White-fronted Geese circling over the Sharp Park golf course. I wandered down there and found them on the fairway at the northwest corner of the course near the south end of Beach Blvd. at Clarendon.

Cooper's are displaying now and would be expected. There are no Northern Goshawk nesting records anywhere in the San Francisco Bay Area or nearby. I assume that most readers of this list understand that this uncorroborated report of displaying Northern Goshawks needs to be considered with extreme caution. -- Joseph Morlan, Pacifica, CA jmorlan (at) ccsf.edu SF Birding Classes start Feb.9 http://fog.ccsf.edu/jmorlan/ California Bird Records Committee http://www.californiabirds.org/ Western Field Ornithologists http://www.westernfieldornithologists.org/ Subject: RE: two Northern Goshawks in foothills west of Los Altos - Feb 18 From: "Bruce Mast" <bmast AT alumni.rice.edu> Date: Wed, 24 Feb 2010 07:24:15 -0800 I have been keeping records of unusual sightings in the Bay Area for the last three years as part of the task of writing the monthly Observations column for Golden Gate Audubon Society.

I saw an adult Goshawk near the summit of Mt. Diablo on a CBC a few decades ago (December 1988) and the bird was confirmed by other observers during subsequent weeks. It's the only Goshawk I have seen in the Bay Area in 35 years of birding here. What about the sightings of migrants recorded by Golden Gate Raptor Observatory? They have found them to be irregular Fall migrants at their study site with most records during November. E.g. there is a photo at: http://www.ggro.org/rare-raptors.html "North American Birds" is now available online and is searchable. That would also be a useful source. It seems odd to me that your list appears to consist entirely of "one day wonders." Were not any of these sightings confirmed by additional observations? The Big Sur sighting you mention is not included in "Monterey Birds" by Roberson, but three other sightings are.

On Feb 18, 2010 there were two adult Northern Goshawks at Hidden Villa in the foothills of the Santa Cruz mountains, west of Los Altos. Hidden Villa is a education center on Moody Rd, about 2-3 miles west of hwy 280. The first bird I saw was circling low over the small valley, gradually rising above the canopy and occasionally vocalizing a repeated a single note call.

Dave Helzer Portland, Oregon Subject: Ano Nuevo State Reserve, Feb.21 From: "Peter Metropulos" <pjmetrop AT pacbell.net> Date: Mon, 22 Feb 2010 22:25:50 -0800 Howdy all ! Yesterday, February 21, I was "on duty" as Docent Naturalist at Ano Nuevo State Reserve. At about 8 AM I stopped at Gazos Creek Coastal Access to look through the several hundred gulls present bathing, drinking, and roosting, at the creek mouth. Among them were one or two "Nelson's Gulls" ( Herring X Glaucous hybrids), first-cycle birds. Ano Nuevo State Reserve was alive with wildlife activity ! While conducting Elephant Seal tours I noticed a huge GULL ROOST at South Point which must have numbered between 5,000- 10,000 birds. Unfortunately access at this location is highly restricted during the seal breeding season (through March) so all I could do was look at them from afar and imagine the possibilities. Also here were at least 200 Brown Pelicans, 70 northbound Brant, an Osprey, a singing Eurasian Collared-Dove(first I've ever seen here), and my first singing Savannah Sparrows and Common Yellowthroats of the year. Peter J. Metropulos [Non-text portions of this message have been removed] Subject: sightings From: Tronthorn AT aol.com Date: Mon, 22 Feb 2010 20:21:23 EST Today, I made a stop at the Skylawn Memorial Park Cemetery to look for raptors. An adult GOLDEN EAGLE was seen flying over the wooded peak and landed in a Douglas Fir observed north of the cemetery. I have not had the time to comment on the Eurasian Teal photographed and posted on penbirds February 8. The teal in the photograph is the male intergrade/hybrid Eurasian Teal x Green-winged Teal that is spending its fourth winter on the pond behind the Nob Hill Market in Redwood Shores. I stopped at the pond today and it was present and has been paired with a female, where the two were first observed on December 5 of last year. On February 15 another intergrade/hybrid male was present, but was quite nervous with its surroundings and departed. There has been a first cycle year male EURASIAN TEAL, where at this time it's plumage is similar to an adult except for the tertials are not full grown. Also present on the pond today was an adult male Eurasian Wigeon and an adult male hybrid Eurasian Wigeon x American Wigeon. On February 20, Leonie Batkin and I birded along the coast. There was just a trickle of gulls north mostly made up of California Gulls. We did find large numbers of gulls at the creek mouths. The lagoon that was at San Gregorio State Beach is no longer as the creek broke through to the sea. Gulls were concentrated along the beach on the south side of the creek, where most people could not cross the creek leaving the gulls to rest. There were ( 1,200 ) gulls mostly made up of California Gulls. There were ( 60 ) Herring Gulls and ( 5 ) Thayer's Gulls. Late was an alternate plumaged Heerman's Gull. ( 2 ) first cycle hybrid NELSON'S GULLS ( Glaucous x Herring Gull ) were among the group. Pomponio State Beach had ( 800 ) gulls mostly made up of California Gulls. A group of ( 20 ) Brant flew by headed north. ( 2 ) adult males and ( 3 ) female Black Scoters were still present. The mouth of Gazos Creek had ( 2,000 ) gulls mostly made up of California Gulls. There were ( 65 ) Herring Gulls and ( 6 ) Thayer's Gulls. There were also ( 2 ) first cycle Heerman's Gulls. Rare on the coast was a second cycle Ring-billed Gull. The number of California Gulls are more than what I would have at this time of the year. There were also many first cycle California Gulls of that age group that I would have not expected until May. The number of Glaucous-winged Gulls are at low with few first cycles around. A first that I have ever observed at Pescadero Marsh was a Pacific Loon foraging in the lagoon east of the Highway 1 bridge. Pigeon Point had ( 44 ) Brant flying north. ( 13 ) Surf Scoters flying north are the first migrants we have observed. A young male Black Scoter was flying north. Migrant Mew Gulls were a tight group of ( 12 ) flying by. ( 2 ) Rhinoceros Auklets were south bound. February 19 at Coyote Point there were ( 3 ) species of cormorants Double-crested, Pelagic and a unexpected first-cycle Brandt's Cormorant. The Brandt's Cormorant eventually flew north away from Coyote Point. ( 6 ) Greater White-fronted Geese on the lawn with Canada Geese were most likely the ones seen at the Belmont Sports Complex Center during the month, but have not been seen recently. A Merlin passed through. ( 30 ) Band-tailed Pigeons are the first I have seen to return to Coyote Point this season. Cedar Waxwings are passing through early at Coyote Point with ( 180 ). On February 8, while counting a push of north bound gulls, I noticed a group of ( 12 ) Aleutian Cackling Geese flying north just below the bluff at the end of Redondo Beach Road in Half Moon Bay. ( 100 ) Brant passed by in the ( 90 ) minute period. Ron Thorn Leonie Batkin Subject: Half Moon Bay birds From: "Gary Deghi" <gdeghi AT h-bgroup.com> Date: Mon, 22 Feb 2010 10:56:15 -0800 I noticed over the weekend that the 14 Greater White-fronted Geese and 3 Cackling Geese were still present at the pond that is between the 11th and 15th fairways at the Half Moon Bay golf course (and that is visible from the end of Bay Hill Road). Sometimes these birds move to the pond that is just inside the front gate to the Ocean Colony community, and on occasion I have seen the Cackling Geese in the farm field east of Highway 1 north of Redondo Beach Road. For the last several weeks there have also been 3 Hooded Mergansers (a male and two females) in the sedimentation pond on the east side of Highway 1 at the Soil Farm (just south of the Redondo Beach Road intersection). I also noticed that the Common Moorhen was still around at the pond across from the clubhouse for the golf course (this area is accessible from the end of Miramontes Point Road off of Highway 1).
