Hi CoBirders
I was at Crown Hill Open Space (Jeffco) today around noon and saw an 
interesting hawk at the south side parking lot. It had a lighter head with 
a dark eyeline, the beak was dark at tip. wings were reddish, but mottled. 
Under side was white with red streaks toward rear. legs were feathered to 
feet. It sat on poles above the parking lot and the cemetary. Maybe one of 
you can spot it and make a better ID than I can. Also two light Red-tailed 
Hawks.

The DUNLIN and male CINNAMON TEAL continue at this location. Late this 
afternoon, the Dunlin was working the rocky edge of the water (i.e., not the 
sandbar) about 200 yards east of the McKay bridge. 

Some of the big ponds on either side of the South Platte River hosted quite a 
few ducks and gulls today. The biggest surprise was an adult ICELAND GULL, seen 
on one of the ponds east of the river, between McKay and 88th. It flew towards 
the southwest just before sunset, so maybe it was heading to one of the lakes 
in the southern Denver metro area for the night?

========================================================================
Report submitted by Rocky Mountain Bird Observatory (jeff.birek AT rmbo.org)
Dinosaur Ridge information may be found at:
http://www.rmbo.org/


Site Description:
Dinosaur Ridge is the only regularly staffed hawkwatch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Dinosaur
Ridge may be the best place in the country to see the rare dark morph of
the Broad-winged Hawk (a few are seen each spring). Hawkwatchers who linger
long enough may see resident Golden Eagles, Red-tailed Hawks and Prairie
Falcons, in addition to migrating Swainson's, Cooper's and Sharp-shinned
Hawks, American Kestrels and Turkey Vultures. Peregrine Falcons and
Ferruginous Hawks are uncommon; Northern Goshawk is rare but regular.
Non-raptor species include Rock Wren, and sometimes Bushtit, Western
Bluebird, Sandhill Crane, White-throated Swift, American White Pelican or
Dusky Grouse. Birders are always welcome. 
The hawkwatch is generally staffed by volunteers from the Rocky Mountain
Bird Observatory from about 9 AM to around 4 PM from the first week of
March to the first week of May.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow small signs from
the south side of lot to hawkwatch site. The hike starts heading east on an
old two-track and quickly turns south onto a trail on the west side of the
ridge. When the trail nears the top of the ridge, turn left, head through
the gate, and walk to the clearly-visible, flat area at the crest of the
ridge.

I am considering going up past Fort Collins to see if the short eared owls are 
still there. Has anyone seen them recently and where were they? I'd love to get 
a good view of these guys!

Hi all!
Had a decent trip to CCSP today in search of Bald Eagles. Saw a total of 7, 
most standing on the edge of the ice in the middle of the lake. One fully 
mature and the rest were varying juvenile years. There was a juvenile in a tree 
by the east entrance marina. He sure wasn't winning any beauty contests but 
wasn't spooked by the wandering folks taking pics under his tree...aahh, 
innocence and youth. Also saw a total of 5 American White Pelicans along that 
same shore. Spring is on its way!! 


Happy birding!

Subject: Boulder Lewis's Woodpecker
From: David Waltman <djwaltman AT comcast.net>
Date: Sat, 7 Mar 2015 19:44:02 +0000 (UTC)
At 11:45 a.m. 3/7/2015 Cheryl and I found a Lewis's Woodpecker along N. 39th 
St. not very far south of Nelson Road.  We first spotted its crow-like flight 
near the road as it flew east and landed on a utility pole about 50 yards east 
of the road at 8922 N. 39th Street.  This is about 10 miles north of downtown 
Boulder and less than a mile east of US 36; about a mile almost due east of The 
Greenbriar Restaurant at Lefthand Canyon.   The only camera I had with me was 
a point-and-shoot with 12x optical zoom.  The bird stayed on the utility pole 
for several minutes so I had no trouble getting identifiable photos, one of 
which I will include with my eBird report. 

David Waltman 
6,000 feet; 1/2 way between Boulder and Lyons  (in the foothills a couple of 
miles west of where we spotted the Lewis's)

Subject: a few birds from Jefferson and Arapahoe counties
From: David Suddjian <dsuddjian AT gmail.com>
Date: Fri, 6 Mar 2015 21:41:48 -0700
As I type a *Nor. Saw-whet Owl* is calling fairly near to my Ken Caryl
Valley home, down out of the woods in Massey Draw drainage where there are
some cottonwoods and willows. On Mar 5 I spotted my first *White-winged
Junco* for my yard list, being the 6th form of junco I've had in my yard.
An *Eastern Downy Woodpecker* in the yard on Mar 4 was just into the hills
and beyond the species' usual distribution in the local region.

Today 3 *Am. White Pelicans* were soaring over Cooley Lake at South Platte
Park, Arapahoe. A 3rd cycle *Lesser Black-backed Gull* was amid some
Ring-billeds on the ice there.

Subject: Re: Continuing Dunlin Seen from McKay and the Platte (Adams)
From: David Dowell <dave1wx AT gmail.com>
Date: Fri, 6 Mar 2015 20:09:58 -0800 (PST)
The DUNLIN and male CINNAMON TEAL continue at this location.  Late this 
afternoon, the Dunlin was working the rocky edge of the water (i.e., not 
the sandbar) about 200 yards east of the McKay bridge.

Some of the big ponds on either side of the South Platte River hosted quite 
a few ducks and gulls today.  The biggest surprise was an adult ICELAND 
GULL, seen on one of the ponds east of the river, between McKay and 88th. 
 It flew towards the southwest just before sunset, so maybe it was heading 
to one of the lakes in the southern Denver metro area for the night?

========================================================================
Report submitted by Rocky Mountain Bird Observatory (jeff.birek AT rmbo.org)
Dinosaur Ridge information may be found at:
http://www.rmbo.org/


Site Description:
Dinosaur Ridge is the only regularly staffed hawkwatch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Dinosaur
Ridge may be the best place in the country to see the rare dark morph of
the Broad-winged Hawk (a few are seen each spring). Hawkwatchers who linger
long enough may see resident Golden Eagles, Red-tailed Hawks and Prairie
Falcons, in addition to migrating Swainson's, Cooper's and Sharp-shinned
Hawks, American Kestrels and Turkey Vultures. Peregrine Falcons and
Ferruginous Hawks are uncommon; Northern Goshawk is rare but regular.
Non-raptor species include Rock Wren, and sometimes Bushtit, Western
Bluebird, Sandhill Crane, White-throated Swift, American White Pelican or
Dusky Grouse. Birders are always welcome. 
The hawkwatch is generally staffed by volunteers from the Rocky Mountain
Bird Observatory from about 9 AM to around 4 PM from the first week of
March to the first week of May.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow small signs from
the south side of lot to hawkwatch site. The hike starts heading east on an
old two-track and quickly turns south onto a trail on the west side of the
ridge. When the trail nears the top of the ridge, turn left, head through
the gate, and walk to the clearly-visible, flat area at the crest of the
ridge.

Greetings All

Yesterday, Nick Moore and I birded from Negronda/Neesopah (Kiowa) to John 
Martin (Bent) to Henry/Holbrook (Crowley/Otero) 


Negronda, Neesopah, Jett Reservoirs all were mostly frozen, but were packed 
with birds in the small areas of open water. Nothing of interest though beyond 
a few migrating McCown's and CC Longspurs (mostly McCown's) and a modestly late 
N Shrike 


John Martin had fewer birds than normal (about 10% of the 6000 Common Mergs and 
5000 Redhead I had last year on nearly the same date). It did, however, still 
have many gulls, and many Herring Gulls. Among the Herrings we found 3 THAYER'S 
GULLS (2 adults, 1 first-year) and a stunning adult GLAUCOUS X HERRING GULL, 
which looked like a giant Thiceland (Thiceland being a bird that looks 
intermediate between Thayer's and Iceland), dwarfing the nearby Herring Gulls 
and having a rather pale frosty back and wings. The one bird present in much 
higher numbers, all day, were N Pintail, with thousands at John Martin. 
Landbirds were nearly absent, but there was another latish N Shrikie 


The Las Animas Fish Hatchery and the SWA just south thereof (Bent County) were 
fabulous with thousands of relatively approachable Snow and Ross's Geese, 
including many lovely Blues (and one SNOW x ROSS'S GOOSE). There were also a 
couple Cinnamon Teal and a nice scattering of other ducks. The wooded areas 
around the fish hatchery had > 200 WC Sparrows, a WHITE-WINGED JUNCO (rarish in 
se. CO), and a SWAMP SPARROW. 


Cheraw was pretty birdless
Holbrook was stuffed full of birds, including a GREATER YELLOWLEGS and a pallid 
second year THAYER'S GULL. 


Meredith remains, for reasons unknown, inaccessible
Henry was mostly frozen, with a modest number of birds in the far back portion 
of the lake. 


Good Birding

Subject: Boyd Lake gulls (Larimer County)
From: quetzal65 AT comcast.net
Date: Fri, 6 Mar 2015 02:42:38 +0000 (UTC)
Boyd Lake State Park (fee area) is currently a magnet for gulls and waterfowl, 
partly because the cold overnight temps have caused most of the nearby lakes to 
freeze. There is enough open water at Boyd Lake (just northeast of Loveland, in 
southeast Larimer County) to support large flocks of Common Merganser, Common 
Goldeneye and Redhead. Approximately 2000 gulls have been amassing there in 
recent days, especially late in the day after gorging at local landfills 
(presumably in the morning too). They are spread out in several large flocks. 
The best viewing has been from the Swim Beach, the Marina spit, and the parking 
lots north of the marina, especially with the afternoon sun behind you. I 
enjoyed the spectacle with a couple other birders late this afternoon (see full 
ebird checklist here: 
http://ebird.org/ebird/view/checklist/email?subID=S22188937 ). 


Highlights were: 
Lesser Black-backed Gull - at least 10 (8 adults, 2 second-cycle) 
Thayer's Gull - at least 8 (4 adults, 4 first-cycle) 
American Herring Gull - I conservatively estimated 120 after counting 70 in one 
flock (several in bizarre immature plumages) 

Glaucous Gull - 1 subadult (at least 3 years old - gorgeous!) 
Glaucous-winged x Herring Gull - 1 first cycle (looked like a big Thayer's with 
really short wings) 

Mallard x Northern Pintail - 2 spanking males identically plumaged!

Subject: Bent County Purple Finch update
From: "Duane Nelson" <dnelson1 AT centurytel.net>
Date: Thu, 5 Mar 2015 19:12:14 -0700
Birders,

 

I was able to help Janeal Thompson see and photograph the single
female-plumaged Purple and Cassin's Finches at my Las Animas feeder
yesterday. It was not surprising the birds were here due to the cold, snowy
conditions. She saw and photographed both. I did not post these sightings to
cobirds due to the unfortunate twin realities that my feeders have been
taken over by Red-winged Blackbirds and I can only put about a cup of seeds
on the platform feeder on the west side of my house and stand by the window
to deter the blackbirds as the finches feed, and that I am not home during
most of the day as I'm busy trying to prepare nesting habitat for Piping
Plovers at John Martin Reservoir.

 

I returned home from work today and put a cup of black oil sunflower seeds
on my feeder at around 4 p.m. Within minutes, the Purple Finch appeared for
a single visit. I assume it was around most of the day looking for a
handout. I'll try to work with interested birders interested in trying for
my finches. I've got to know in advance that you're coming. We may be able
to figure out alternative strategies for observing the birds.

Subject: Continuing Dunlin Seen from McKay and the Platte (Adams)
From: Kathy and Jeff Dunning <mihmdunning AT gmail.com>
Date: Thu, 5 Mar 2015 16:45:20 -0700
Hi all -

This afternoon I made a quick trip up to the location where the Dunlin
has been intermittently seen over the past week.  When I arrived, it
was on the sandbar on the east side of the McKay bridge.  I was able
to get some poor-quality pictures.

Shortly after I arrived, it vanished and I could not re-find it on
either side of the bridge.

Also in the area was one male Cinnamon Teal (and gobs of Northern Shoveler)

This is a challenging location to bird as the bike-trails in the area
are closed and gated, so viewing is from McKay Road which is fairly
narrow and busy.

Good birding,

Kathy Mihm Dunning
Denver

----------------------------------------------------------------------

Observation start time: 10:15:00 
Observation end   time: 15:00:00 
Total observation time: 4.75 hours

Official Counter:        Roger Rouch

Observers:        

Visitors:
None.


Weather:
Pleasantly cool with temps in the upper 20's and low 30's with a light
breeze generally from the SE. Mostly cloudy with a late break in the clouds
and sun at day's end.

Raptor Observations:
Two Golden Eagle were first observed flying tandem over two humps and
proceeded to spiral over the southern end of the ridge then over the
observation site and north out of sight.  A brief talon grapple was
suspiciously like local behavior, but both were counted as migrating. 
Also, to acknowledge the common sighting of local Prairie Falcon, but the
one counted as migrating was on a direct flight north out of line of
sight.

About ten local Red-tailed Hawks were sighted or re-sighted. Also, a local
Kestrel.

Non-raptor Observations:
Few non-raptors with a couple of marauding Black-Billed Magpie, a Scrub
Jay, and a chickadee.

Predictions:
The next couple of days should be the first days of warm sun for sometime,
which may bode well for more activity.

Note that the trail is packed snow, but will be icy or sloppy for a while. 
The observation site has small areas of bare ground starting to show.
========================================================================
Report submitted by Rocky Mountain Bird Observatory (jeff.birek AT rmbo.org)
Dinosaur Ridge information may be found at:
http://www.rmbo.org/


Site Description:
Dinosaur Ridge is the only regularly staffed hawkwatch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Dinosaur
Ridge may be the best place in the country to see the rare dark morph of
the Broad-winged Hawk (a few are seen each spring). Hawkwatchers who linger
long enough may see resident Golden Eagles, Red-tailed Hawks and Prairie
Falcons, in addition to migrating Swainson's, Cooper's and Sharp-shinned
Hawks, American Kestrels and Turkey Vultures. Peregrine Falcons and
Ferruginous Hawks are uncommon; Northern Goshawk is rare but regular.
Non-raptor species include Rock Wren, and sometimes Bushtit, Western
Bluebird, Sandhill Crane, White-throated Swift, American White Pelican or
Dusky Grouse. Birders are always welcome. 
The hawkwatch is generally staffed by volunteers from the Rocky Mountain
Bird Observatory from about 9 AM to around 4 PM from the first week of
March to the first week of May.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow small signs from
the south side of lot to hawkwatch site. The hike starts heading east on an
old two-track and quickly turns south onto a trail on the west side of the
ridge. When the trail nears the top of the ridge, turn left, head through
the gate, and walk to the clearly-visible, flat area at the crest of the
ridge.

Subject: Dr. George Archibald, co-founder of the International Crane Festival, presentation
From: taarmstr AT adams.edu
Date: Tue, 3 Mar 2015 18:58:18 -0800 (PST)
The keynote speaker for this year’s spring Crane Festival in Monte Vista, CO, 
is Dr. George Archibald from the International Crane Foundation. Dr. Archibald 
has studied cranes for over 45 years since he worked on the vocal behavior and 
evolution of cranes for his Ph.D. at Cornell University. He has devoted his 
life to the conservation of cranes and the habitat on which they depend. Since 
he co-founded the International Crane Foundation in 1973, Dr. Archibald has 
studied the ecology of eight species of cranes in Australia, Bhutan, China, 
Iran, India, Japan, Korea, Russia and the US. Dr. Archibald has published 
dozens of research articles and book chapters on cranes and their conservation, 
and he has organized more than 900 researchers in 64 countries to study cranes. 
His more notable awards include a MacArthur Award in 1984, a Gold Medal from 
the World Wildlife Fund in 1985, the Audubon Society’s distinguished 
conservationist award in 1993, and the Aldo Leopold Award for Distinction in 
Environment and Conservation in 2007. Dr. Archibald is planning to reduce his 
speaking engagements to begin work on his memoirs, so this may be one of our 
last opportunities to hear one of America’s leading conservationists discuss 
his life’s work. Dr. Archibald will be speaking at 7:30 p.m. at the Vali 3 
Theatre at 139 Adams Street in Monte Vista, Colorado on Saturday, March 14th.

Pygmy Nuthatch - pair     at feeder



Walked outside to get closer look with handful of live mealworms hoping to
get their attention

one of the Pygmys perched on my fingers, grabbed a mealworm; and left

Subject: Rosy-Finches - Golden - Jeffco - Only a couple
From: Ira Sanders <zroadrunner14 AT gmail.com>
Date: Thu, 5 Mar 2015 07:29:31 -0700
Birders,
I've seen only a couple of Rosy's this am.  There is a Sharp-shinned Hawk
sitting on the north side of the house and a mule deer eating their seed.
I really doubt there will be many today with all the sunshine.
On a sad note, I believe that one of the "fluffy" Rosy's met it's end
yesterday or last night.  We returned last night to a lot of feathers on
the front porch.  Looked to be the right color.  Maybe the one I almost
picked up yesterday.

Subject: Monte Refuge Filled with Birds
From: <cougar AT gojade.org>
Date: Wed, 4 Mar 2015 10:04:32 -0700
The Monte Refuge has bountiful numbers of Sandhill Cranes, Canada, Cackling, 
Snow and Ross’ Geese, Mallards, Pintails, Ring-necked Ducks and many Bald 
Eagles watching them closely. The refuge still has snow cover which has 
affected usual feeding and roosting patterns. Best place at the moment is on 
Hwy 15, 1 mile south of the Headquarters at the turnouts. 


One particular bird caught my attention yesterday was a leucistic Cackling 
Goose. This bird has the normal head and neck of the Cackling, but the body is 
white. A few tail feathers are dark. This bird was likely the same one I saw 
about 3 years ago. So be on the lookout. 


Monte Vista Crane Festival is March 13-15 and there should be plenty to see. 
Google the Crane Festival for a schedule of events.

There are Rosy-Finches here today.  There are now 3 who are fluffy and

From: Thomas Heinrich <teheinrich AT gmail.com>
Date: Wed, 4 Mar 2015 07:30:57 -0700
The Northern Cardinal was here this morning just after 7:00. The cardinal has 
been visiting my feeders much more frequently for the last 4-5 weeks. It had 
been coming in bursts of a few days with prolonged absences. Perhaps the 
extended cold and snowy weather has been a factor. 


Also at the feeders over the last couple of days:
Spotted Towhee
Cassin's Finches (up to a dozen)
Pine Siskins (up to 5)
Pine Grosbeak (one yesterday)

Subject: Birding trip to Brazil
From: Norm Erthal <nerthal AT comcast.net>
Date: Tue, 3 Mar 2015 10:12:12 -0800 (PST)
 I have a birding trip planned for the southeast Brazil rainforest and the 
southern Brazil state of Rio Grande do Sul. It will be about $6,000 plus 
airfare that I have found for less than $1,400. This is higher than I was 
hoping for but still $1,400 to $2,000 less than comparable trips. We would 
leave the US on October 20, arriving in Rio on October 21 and leaving 
Brazil for home on November 7. If you are interested, please contact me for 
a detailed itinerary and additional information. The possible species list 
totals 730 species of which nearly 400 are Brazil or regional endemics.

Good catch. In the dying light I clearly missed the thicker bill that does 
indeed, make this bird a ruddy duck. Sorry for the missed ID.

Hi All,

I am currently looking at a fairly worn male Ruddy Duck in City Park (Denver). 
I 

believe that this is the bird reported yesterday as a Black Scoter. There are 
currently no accepted eBird records of Black Scoter in either February or 
March.

Birders,
There are at present, about 40 Rosy-Finches at the house.  They were so
fixed on food this morning that they stayed on the fire pit feeding while I
was still spreading seed on the patio.
It is starting to snow  so that may account for the behavior.

Subject: Glaucous Gull - Boyd Lake, Larimer
From: David Wade <davespeedbump AT gmail.com>
Date: Mon, 2 Mar 2015 21:02:36 -0800 (PST)
Greetings All,

Following a hot tip, Ken Pals, Nick Komar and I found a third cycle 
Glaucous Gull at Boyd Lake in Loveland today (March 2). Nick (of course) 
first spotted the large, white-wing- tipped gull flying towards the north 
end of Boyd Lake today around 4 pm. It landed on the ice where it preened 
and rested long enough to get some distant digiscoped shots. It was last 
seen flying south over the lake. Boyd Lake is a state park and requires a 
pass to enter.

There are 5 shots in the photostream, here is first 
one: https://www.flickr.com/photos/122221383 AT N05/16700887935/

Observation start time: 09:30:00 
Observation end   time: 14:00:00 
Total observation time: 4.5 hours

Official Counter:        Joyce Commercon

Observers:        

Visitors:
A few hikers were out on the snowy trails--perhaps five in total. Two
hikers, one with a dog, took in the view briefly at the HawkWatch site.


Weather:
The day was sunny and cold (just above freezing) with clear blue skies
through the morning, with small cumulus and thin translucent clouds rising
up in the west and south in the early afternoon. Wind was light and mostly
from the east. Visibility was not as good as usual, but acceptable (>10 km)
above the valleys, which held a haze that reduced visibility somewhat
(maybe to 7 km). The haze was noticeably brownish to the northeast and over
the I-70 corridor. Solid snow cover in the area made it easy to see
anything that moved.

Raptor Observations:
There were few active locals and no active migrants observed today. The
highlight of the day was an adult, light-morph Harlan's Hawk that was
spotted flying low and slow in Rooney Valley, heading south. Not migrating
today, but probably soon. One local adult Red-tailed Hawk was observed
perching and hunting, mostly in Rooney Valley. A local Prairie Falcon
perched on the power pole directly north of the HawkWatch site then headed
east to Green Mountain where it circled low, presumably to hunt.

Non-raptor Observations:
A group of Bushtits made their way north along the west side of the Ridge
in the morning; a few hours later over twenty-five bushtits (accompanied by
a few individuals of a Chickadee species) bustled back south along the same
section of Ridge. Also seen or heard were Black-billed Magpie, Raven,
Townsend's Solitaire and House Finch.
========================================================================
Report submitted by Rocky Mountain Bird Observatory (jeff.birek AT rmbo.org)
Dinosaur Ridge information may be found at:
http://www.rmbo.org/


Site Description:
Dinosaur Ridge is the only regularly staffed hawkwatch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Dinosaur
Ridge may be the best place in the country to see the rare dark morph of
the Broad-winged Hawk (a few are seen each spring). Hawkwatchers who linger
long enough may see resident Golden Eagles, Red-tailed Hawks and Prairie
Falcons, in addition to migrating Swainson's, Cooper's and Sharp-shinned
Hawks, American Kestrels and Turkey Vultures. Peregrine Falcons and
Ferruginous Hawks are uncommon; Northern Goshawk is rare but regular.
Non-raptor species include Rock Wren, and sometimes Bushtit, Western
Bluebird, Sandhill Crane, White-throated Swift, American White Pelican or
Dusky Grouse. Birders are always welcome. 
The hawkwatch is generally staffed by volunteers from the Rocky Mountain
Bird Observatory from about 9 AM to around 4 PM from the first week of
March to the first week of May.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow small signs from
the south side of lot to hawkwatch site. The hike starts heading east on an
old two-track and quickly turns south onto a trail on the west side of the
ridge. When the trail nears the top of the ridge, turn left, head through
the gate, and walk to the clearly-visible, flat area at the crest of the
ridge.

Eagle perching on a tall pole over a prairie dog field; and then soaring 
across the field-- a disappointment for us both, it would seem (he failed 
to catch anything, and he flew before I could try a digiscoped picture).  
Still- always a treat.
 
The location was Roxborough Park Road, the unpaved section bewteen Titan 
road and Sharptail Ridge open space.

Subject: Around Boulder County, 2/28-3/1
From: Ted Floyd <tedfloyd57 AT hotmail.com>
Date: Mon, 2 Mar 2015 09:06:22 -0800 (PST)
Hello, Birders.

Sat. afternoon, Feb. 28, Hannah Floyd and I were delighted at *Erie 
Reservoir*, Boulder County, by two of the most challenging taxa for 
Colorado birders: *Larus* gulls and *Streptopelia* collared-doves. In the 
decently large gull flock on the reservoir proper, we saw two definitive 
alternate ("spring adult") *California Gulls* and a *Hot Pink Ring-billed 
Gull*. I'm not aware of too many reports in recent years of these hot pink 
Ringers, but they were legion a dozen years ago in the Front Range metro 
region. Back then, all these pink Ring-billed Gulls were coming from fish 
farms in the Pacific Northwest. There's a great article about this in 
*Birding* by Lisa Hardy: "The Peculiar Puzzle of the Pink Ring-billed 
Gulls," Oct. 2003, pp. 498-504. We also saw a flock of tricky 
*collared-doves*. Here's a photo, and it shows why we need to scrutinize 
practically every collared-dove we see in Colorado, even the superficially 
"normal" ones:

http://tinyurl.com/Strepto-2015-02-28

At daybreak on Sat., I looked for gulls at the *Valmont Reservoir complex*. 
It was swarming with gulls! But I couldn't really see them because of the 
thick steam rising from the surfaces of all three reservoirs. The *Common 
Merganser* flock there was fantastic: hundreds of males gathered near the 
south shore of Valmont Reservoir proper, and engaged in a frenzied chorus 
of wild woofing calls. It was magical, bacchanalian, like cranes or 
prairie-chickens in the morning mist.

And over at Walden Ponds on Sat. morning, Cottonwood Marsh was frozen over, 
but *Wally Toevs Pond* had a bit of open water and around 150 ducks, of 
which more than half were *Redheads*, almost all males, and they were 
chorusing. But their chorusing is very different from that of the 
mergansers, a soft wailing, whistled and melancholy. A beautiful *Harlan's 
Hawk* sailed right over, catching the rising sun just right. 
*Nuthatch=nelsoni.* *CalGull=albertaensis.*

Sat. afternoon, at the *Kenosha Road Boulder Creek crossing*, a pair of *Great 
Horned Owls* sat in a cottonwood, one large, one larger, so I'm guessing 
male and female, respectively, mated up and ready to go. And a *"Mountain" 
Downy Woodpecker* (*leucurus* subspecies-group) was highly industrious. 
Here's video of the bird: http://tinyurl.com/DoWo-2015-02-28

Over at *Waneka Lake*, there remains a small patch of open water, kept 
ice-free at night by the splish-splashing of the several thousand 
*white-cheeked 

geese*. All the geese go away during the day, but a lone hen *Hooded 
Merganser* hangs on. Here's a photo from Sat. evening: 
http://tinyurl.com/HoMe-2015-02-28. Meanwhile, at least two phenotypically 
"good" *African Collared-Doves* are hanging out nearby, in and around the 
yards along Salina Street. And one of the *ravens* there continues to 
impress with its quacking calls, small size, and somewhat crow-like 
proportions; still need the definitive photo (or dead bird?) for eBird... 
;-)

Sun. afternoon, Mar. 1, I explored *beautiful Gregory Canyon* and its 
various "tributaries." I came upon two Red Crossbill flocks (*n*=9, *n*=10), 
both of them confusing: seemingly small-billed birds going to town on 
spruce cones, but giving typical Type 2 flight calls. I guess that makes 
them *Type 2 Red Crossbills*, yes? Audio: http://tinyurl.com/ReCr-2015-03-01

And down along *Boulder Creek* Sun. afternoon, there was an *American 
Dipper* doing the dipper thing just upstream from bridge at the Boulder 
Public Library. Also, another flock of Red Crossbills (*n*=10), again in a 
spruce, but silent, so untyped. And a *Great Blue Heron* impersonating a 
plastic owl. Video: http://tinyurl.com/GBHe-2015-03-01

The feeders will not be up the rest of the day in the front of the house as
the elk got 2 of them 2x and 2 others already this morning.
Sorry.

Hi all

My wife and I ventured out for the owls yesterday.  In the AM no luck.  At 
6:10PM-ish there were six cars waiting for the owls in various places along 
Buckeye Road.  A few of us, headlights off, agreed to flash headlights if 
seen--that system worked.  They appeared in their normal place 2086 Buckeye 
Rd--a birder acquaintance of mine lives there--one jumping up from the 
field.  As that one flew east to slight ridge near Rawhide Plant wind break 
another one appeared interacting with it.  

Note:  That birder acquaintance of mine also mentioned during the third 
week of April these same fields bring many (dozens+) Long-billed Curlews 
during spring something to keep in mind.

Also, two Lapland Longspur continue at Weld CR 33 in Nunn btw WCR 100/WCR 
98--walking the area is best to hear and find them.

Thanks Gary Lefko, Nunn

Birders,
With the sunny weather the number of Rosy's have dropped significantly.
This morning there is only about a dozen birds.
The numbers will probably go up tomorrow with snow coming.

Subject: Buckeye Road (LCR 82) 3/1
From: "Mark Miller" <snowy.owlets AT gmail.com>
Date: Sun, 1 Mar 2015 21:49:49 -0700
Hi Everyone-

 

This evening 3/1, Marcia Marvin and I decided to try for the Short-eared
Owls that have been reported along Buckeye Road. We watched and waited at
the west end of the field with the hunting blinds. Several other cars were
parked at intervals toward the east and the power plant. There were three
harriers working the field until about 5:45 pm, then quiet. By about 6:15, I
had not seen any owls, so I drove back toward the power plant. At the
entrance, I talked to some people who said they had seen two birds fly east
over the rise, so I drove another 200 yards or so east and saw two birds in
near darkness on a telephone pole on the north side of the road (the spot is
closer to the railroad tracks than to the power plant). One was divebombing
the other. As the one swooped past the other, the perched one let out a
squawk. The squawk resembled a short version of a Short-eared Owl call. I
have not seen this behavior before in either Great Horned Owl or Short-eared
Owl, so I was left a bit confused. Could Short-eared Owls be getting feisty
for the breeding season now, or did I just see two feisty Great Horned Owls?

Subject: Black Scoter- Denver
From: "'Norm Lewis' via Colorado Birds" <cobirds AT googlegroups.com>
Date: Sun, 1 Mar 2015 22:31:03 -0500
I went out on a circle around nearby sites this afternoon, mostly to scout a 
route for an upcoming museum birdwalk, but certainly keeping an eye open for 
anything notable. There were a few birds of interest here and there, but the 
most interesting things I found were assemblages- who was present, and who 
wasn't. 

I started at the South Platte at 78th Ave., where most of the usual suspects 
were present, including zillions of shovelers, bazillions of goldeneye, and 
unlikely-sounding numbers of the regulars. The male Barrow's goldeneye was 
hanging out with commons in the customary spot near the big water tank. There 
were also good numbers of pintails, which seemed somewhat restless. A flock of 
a half dozen flew continuously up and down the river while everyone else mostly 
just hung out. Of note: I saw not a singer ring-neck, redhead, canvasback or 
hooded merg. 

From there it was on to Rocky Mountain Arsenal. An open area at the north end 
of Lake Ladora had approximately four hundred redheads, sixty ring-necked 
ducks, eight hooded mergs and one canvasback. Apparently I had discovered the 
Land of Missing Duckage. A small open area on nearby Lower Derby Lake had 
thirty canvasbacks and not much else. Go figure. 

The most interesting bird there was an odd red-tail. There always seem to be a 
few dark red-tails along the road out to the east part of the refuge, and today 
I saw at least two. I got a mediocre look at one of the birds as it flew away 
at some distance. It was an overall dark bird, and had a white tail with a red 
margin. This doesn't fit any of the morphs/races of red-tail that I am familiar 
with. Unfortunately, no chance for a picture. It was either an unusual bird or 
I was hallucinating, which is certainly not out of the question. Maybe it's 
time for my monthly meds adjustment..... 

After a quick look at Bluff Lake/Sand Creek, I circled back in the direction of 
the museum and decided to have a quick look at the lakes there. Ferril Lake was 
frozen and empty, so I popped over to Duck Lake to check on the cormorant 
colony. At least fifty birds are back on nests. There is a very small patch of 
open water at the northeast corner of the lake, and upon taking a quick peek in 
the dying light, I spotted a female black scoter swimming with a few coots. 
With another frigid night coming up, the open puddle may be gone by tomorrow. 
Unfortunately, it was almost dark by the time I found the bird- too late to do 
a quick post. If the water stays open at all, the bird may still be there in 
the morning.

This morning during a CSU Field Ornithologists field trip, Megan Miller and 
I spotted a female Barrow's Goldeneye at Windsor Lake. The bird was first 
found yesterday. 
No sign of the adult male Long-tailed Duck that I found 
originally...although it was seen yesterday. All the waterfowl at Windsor 
Lake is concentrated where the only open water is at about the middle of 
the lake. 

Check out us on faceook "Field Ornithologists of Colorado State University"

Subject: Purple and Cassin's Finch update, Bent County
From: "Duane Nelson" <dnelson1 AT centurytel.net>
Date: Sun, 1 Mar 2015 14:28:29 -0700
Birders,

 

I thought today might be a no-show for Purple and Cassin's Finches at my
feeders in Las Animas, but the Cassin's Finch finally appeared at 12:40 p.m,
and the Purple Finch at 1 p.m. I must have captured lightning in a bottle,
because both posed "side by each" (an old Upper Peninsula of Michigan term)
on my platform feeder at 2:20 this afternoon. If present, the birds are
never the first birds of the day, or the last birds of the day to leave, and
may be most reliable between noon and 3 p.m.

 

Duane Nelson

Las Animas, Bent County, CO

Subject: Rusty Blackbird(s) Sandstone Ranch, Weld County (3/1)
From: "'Chris Knight' via Colorado Birds" <cobirds AT googlegroups.com>
Date: Sun, 1 Mar 2015 11:53:31 -0800 (PST)
Hi All,
 
I just returned from birding at Sandstone Ranch east of Longmont (Weld 
County side) and noticed one (possibly two) Rusty Blackbirds along the St. 
Vrain at the far SE border of the park. This is about a half mile 
downstream (I believe) from where a small flock of Rustys was reported 
recently by Steve Mlodinow.
 
Other birds at the "ranch" today were a nesting Great Horned Owl and a Barn 
Owl at the usual roosting location. Otherwise it was pretty slow.
 
Good bidring!

The one owl seen from CR82 appeared south of the road at about 6:05 pm. This 
was in the field with the hunting blinds, west of the power plant entrance 
(BTW, visitor overlook was still closed). The bird was very far away and landed 
a few times on short posts along a private roadway. It got closer as light 
faded. Bring a telescope.

A small group of us were able to see short-eared owl in the same general 
vicinity that they have been seen over the last few days. It was off County 
Road 82 near the Rawhide plant, a few miles west of I 25. The address that 
Rachel Hopper gave, 2086 Buckeye Rd. , is close to where it was sited. 

 I admit my directions are not very complete but they're the best I could come 
up with right now. Nick Komar was there as well as several others of whom I 
can't whose name I can't recall. Drat! 

 My friend, Ed Secor, and I saw two furuginous hawks and a bedraggled Redtail 
hawk on the way to see the owls.

Hi CoBirders
I was able to see two American Dippers in Clear Creek< east of Lowell 
Blvd.(Adams). One was about half way to the I 76 bridges. The other was at 
the I 76 bridges. I didn't see any interaction or vocalizations between the 
birds, but they were near enough that sound would have carried. I've found 
one dipper regularly throughout the month.

Date: Sat, 28 Feb 2015 22:33:37 -0700
We have had a few inches of snow this past week and temperatures in the
teens and twenties in Lamar (Prowers). The Yellow-bellied Sapsucker found
by Dave Leatherman earlier in the year is still in the southern most pine
trees on the Parkview Avenue (west) side across from house numbers 1305 and
1305A.  Willow Creek Park, Lamar Community College, Fairmount Cemetery and
Willow Valley Subdivision are all hosting Red-bellied Woodpeckers,
White-breasted and Red-breasted Nuthatches, and other expected winter
visitors in good numbers. Yesterday, 27Feb2015, a lone Brown Creeper was
busy foraging on cottonwood trunks near the feeder across from the college
library. (For those interested,the Northern Cardinals are being seen
regularly on the south end of LCC near the housing development.)  A bit
farther south of LCC, along Willow Creek, a Northern Mockingbird was found
in some tamarisk, but the Brewer's Blackbirds and the lone Common Grackle
seen by Jane Stulp and myself, respectively, have not been there for a
while.  The Russian olives at the Prowers Medical Center Campus host Cedar
Waxwings, several Red-winged Blackbirds and American Robins.  A few
beautiful Eastern Bluebirds often line the fence on the east (prairie) side
of the PMC Drive.

Subject: Purple and Cassin's Finches in Bent County
From: "Duane Nelson" <dnelson1 AT centurytel.net>
Date: Sat, 28 Feb 2015 20:12:43 -0700
Birders,

 

I've had infrequent sightings of single female-plumaged Purple and Cassin's
finches at my feeders in Las Animas (Bent County) since early January.
Purple Finch is a review species in Colorado, and Cassin's Finch is rare so
far from the mountains. Until today, I'd never seen both species at the same
time. This afternoon, I finally had both birds on the feeder seven feet from
my family room window at the same time, and actually nailed photos of them
interacting with each other. I'll gladly send photos to those interested.

 

I welcome visitors, but of course there's a caveat. They are unpredictable,
often disappearing for days or weeks on end. They may be more reliable in
bad weather. And, I've got a problem with Red-winged Blackbirds. If I fill
my feeders, I will have hundreds around, and they drive off other birds. For
the past few days, I've only been able to put a small amount of seeds on the
tray feeder nearest the window on the west side of my house, as blackbirds
are more shy than finches, and will fly off if they see me inside. When the
blackbirds leave without successfully feeding, I put out more seed, and hope
the finches take advantage of these brief opportunities to visit. So far,
this has worked, but I can't always be around to do this drill.

 

I went to John Martin Reservoir today. The lake, completely open last
Thursday, is currently mostly iced over. Some early migrant American White
Pelicans stand stupidly on islands surrounded by ice, waiting for it to
melt.

Subject: Williamson's Sapsucker and Aggressive Dusky Grouse, Heil Ranch Boulder County
From: "Bob Spencer, the younger" <bspence4430 AT gmail.com>
Date: Sat, 28 Feb 2015 18:56:48 -0800 (PST)
Sondra and I had a very nice snow shoe hike today in Heil Valley Ranch, 
Boulder County Parks. A highlight was when we stopped near the Ponderosa 
Loop overlook to view a Townsend's Solitaire, and a male Dusky Grouse 
sauntered up to us through the snow. We were thinking that it was amazingly 
tame, when all of a sudden it started attacking our snow shoes, and then 
jumped up and pecked at my day pack (I might have vocalized an octave 
higher than usual). As we continued on, congratulating ourselves for being 
treated to such a special unique close encounter with nature, we came upon 
a pair of signs that said "Please Stay Clear of Aggressive Grouse". I see 
that there are posts on Facebook concerning this Grouse for at least a year 
now. Nevertheless, it was fun to see its subtle but striking markings so up 
close. On the way back down the trail (2 miles from the southern trail 
head) we were surprised to see a female Williamson's Sapsucker working a 
trunk of a Ponderosa pine tree by the trail.

Several birders watched about 30 rosy-finches swirl from treetop to treetop
around Ira and Tammy Sanders home from about 10:30 to noon today.  We found
at least one black, one brown-capped, and the rest gray-crowned.  One or two
gray-crowned landed on a tray feeder in front, but the flock was kept at bay
by a Sharp-shinned Hawk that persisted much of the time in the neighbor's
tree.  The Gray-crowned Rosy-Finch with puffed-up feathers photographed
yesterday that appears to be sick fed on the pavement right in front of us
for a while.  Thanks, Ira and Tammy!

On our S. Platte duck walk (hard on the knees to do that for miles), we had
a Dunlin and a Amer. Pipet at the S. Platte Bridge on McKay Rd (about 9300
N) north of 88th St.

The Dunlin last seen flying hard upstream (SW) but was actively flying
around sand bars and low water spots for a while.

We did NOT see any Barrow's Goldeneye or any Mergansers, but did see a
female N. Harrier.

I wonder if the increased numbers of Cooper's Hawks is a reason for the 
decline of both Sharp-shinned Hawks and American Kestrels.  I presume 
the kestrel numbers have declined over the years do to a few things, one 
being trichinosis, but are Cooper's Hawks taking their toll on these 
little raptors as well?

I just talked to Davis and he tells me he is planning on leading the group
tomorrow.  Details below,

*Saturday, February 28, 8:30 a.m. - 1:30 p.m.*
"Ducks Along the Platte with 'Davis'!"
We’ll drive down to 88th and Colorado (can meet there at 9:20). Walk along
the South Platte river trail for 2-3 miles. If it’s good and cold (dress
warmly), we may see 17 species of waterfowl, including Barrow’s Goldeneyes
and the occasional Long-tailed Duck! Great for beginners, as most male
ducks have obvious fieldmarks. Meet at East Boulder Rec Center at 8:30
a.m., plan to be back to Boulder by 1:30 pm. Contact Davis at
303-823-5332.   No reservations necessary.

I swung by Ira's today to admire the rosy-finches. As I parked, a kestrel 
came zipping toward his front porch, pursuing a puffed brown rosy. It 
missed and smacked into the front door. It wasn't hurt and Ira came out to 
see what the fuss was. Apparently the kestrel hangs out in the same tree 
with the rosies and leaves them be. Ira guessed it was after this one, 
which has been acting sick and is continually puffed up: 
http://i.imgur.com/fk3Ll0b.jpg. (Is that a white-winged junco keeping it 
company?)

Thanks for shoveling that path, Ira, that was very kind of you. It was 
lovely watching 115 finches descend on your bird seed. Thanks for being a 
great host to both birds and birders!

My count on Rosy-Finches: 9 Hepburn's Grey-crowned, perhaps a Brown-capped 
(I'm unsure: http://i.imgur.com/tbPGrss.jpg), and the rest were 
Grey-crowned (interior form). I didn't spot any Black.

Having worked on the Cape May Raptor Banding Project this past fall, I had
many discussions with a variety of people about the diminishing Sharpie
populations.  It's been a noticeable trend in the capture data and the
hawkwatch count data that Sharpies have been decreasing steadily over the
last decade or so while Cooper's Hawks have been steadily increasing.  One
of the major theories for this among everyone I talked to was the
increasing fragmentation of forested habitat.  It might be that Sharpies
are more reliant on dense vegetation and canopy cover to catch their
unwitting prey, while Coops have been able to adapt to an increasingly
urbanized environment.  This is just a theory and I'd be interested to see
whether any data has been collected to back this up, but there has
definitely been a noticeable shift in the proportions of these two
Accipiters in the east.  That being said, we did have Sharpies make
multiple passes at the pigeons we used as lure birds.  They commonly landed
on starlings (even the tiny males would go for a starling), but I believe
we only ever had one female land on a pigeon long enough for us to trap
her.  There was a relatively recent discussion on the weight-carrying
capacity of Sharpies on the CFO Facebook page if anyone is interested.

From: William H Kaempfer <William.Kaempfer AT Colorado.EDU>

Nick,

I went to CBC data for Colorado to see what it says. From the early 1990s up 
through about 2005 or 2006 both Sharp-shinned and Cooper’s Hawk numbers 
increased steadily: up 125% for Sharp-shinned and 135% for Coopers. Since then, 
however, Sharp-shinned have gone back to about where they were while Coopers 
have doubled again. During the period from the 91st CBC (which if I recall 
means the actual end year is one before, so 1989-90) to the 105th CBC, 
Cooper’s numbers grew fairly steadily from just under .01 per party hour to 
just over .02. in 15 years. But then things really took off, for every year 
since count number 106, Cooper’s Hawk counts have been between .03 and .04 
with a high of .0418 on the 111th count. 


What about Eurasian Collared-Doves? Their numbers have grown 12 fold in the 
last decade. My conclusion is that Cooper’s Hawks are an even greater 
beneficiary of all of that food source that is now available and they are 
prospering. But, more Cooper’s Hawks might mean fewer Sharp-shinned Hawks.

Sharpies take Eurasian Collared-Doves on a regular basis. The dove is almost 
50% larger than the hawk by mass. This brings up a question: why are there not 
more Sharp-shinned Hawks around? There must be more influential constraints on 
the hawks population than winter food supply. Any thoughts on what those 
constraints might be?
