Subject: Injured Flicker

Hi there. Does anyone know where I can take an injured Flicker (we think
it hit a window)? It is alert and can move its wings, but it is not flying
away. I'm not sure if it can move its legs. We kept it in a box overnight
hoping it would take off in the morning, but no luck.

Thanks,
Nicolle Martin

Subject: Nathan Pieplow talk at Boulder Audubon monthly program
From: Pam Piombino <piombino.pam AT gmail.com>
Date: Tue, 27 Sep 2016 09:04:49 -0600
Tonight!! 7:15 p.m. at the Unitarian Universalist Church of Boulder, 5001
Pennsylvania Ave. (west off 55th St. between Arapahoe and Baseline)

*The Amazing Sounds of Birds*
What bird uses its voice to echolocate inside dark caves? Which bird sings
a duet with itself? Which bird sings over a thousand different songs? In
this presentation, Nathan Pieplow, author of the forthcoming Peterson Field
Guide to Bird Sounds, will share some of his most remarkable audio from
over a decade of recording birds in the field. You will see the sounds as
well as hear them, and learn the stories of the birds that made them, and
what some of those birds are actually saying.

Nathan, in addition to authoring the forthcoming Peterson Field Guide to
Bird Sounds, is the founder of the website Earbirding.com.

 

He is one of the authors of the Colorado Birding Trail, and a former editor
of the journal Colorado Birds. He teaches writing and rhetoric at the
University of Colorado in Boulder.

We hope to see you there!

Thanks,

Subject: Common Tern & Red-breasted Merganser - Mesa County
From: Mike Henwood <mhawkhen AT gmail.com>
Date: Mon, 26 Sep 2016 18:47:28 -0600
On Sept. 24 a Common Tern was seen flying over and around Highline Lake
State Park.
Was an adult nonbreeding bird.  Obvious black patch behind eye with all
gray wings and some black on primaries.  Rare spring & fall migrant on WS.

Today along the Colorado River at the Grand Junction Wildlife Area a group
of us saw a male Red-breasted Merganser.  Uncommon spring and fall migrant
that normally does not show up until  late October.

Subject: Another day, another owl. Bird Conservancy Chico Basin Ranch Banding Report 9/26/16
From: lmkoitsch AT gmail.com
Date: Mon, 26 Sep 2016 12:21:25 -0700 (PDT)
Hiya!

We caught and banded our second *Northern Saw-whet Owl* this morning here 
at Chico Basin Ranch (fee area). This time it was a young male. The *White-eyed 

Vireo* that was banded over a week ago was recaptured again today and this 
time, it had gained significant fat/weight. In fact, it gained over half 
the entire weight of a kinglet (3 grams)! 

There was a large flock of adult *White-crowned Sparrow*s, both *Gambel's* 
and *Mountain*, flying around today and we managed to net and band several 
of them. 

Highest numbers still went to *Hermit Thrush*, which are once again in 
abundance this season. 

Remember, last day for fall banding here at Chico Basin Ranch is this 
Saturday, October 1st.

Subject: Ruby-throated Hummingbird in Bent County
From: Duane Nelson <dnelson1 AT centurytel.net>
Date: Mon, 26 Sep 2016 09:27:41 -0600
Hello Birders,

When it rains, it pours. Ruby-throated Hummingbirds, for me, in Las 
Animas, Bent County. A little more than a week ago, I had a male 
Ruby-throated Hummingbird, seen by many observers. On Saturday evening, 
this immature - female showed up, making erratic visits to my feeder. I 
was finally able to photograph it a few minutes ago. I am pretty 
fortunate because my default hummingbird here on the eastern plains is 
Black-chinned, the most similar hummingbird to Ruby-throated. The key 
field marks are discussed in many guide books. My first clue is the 
overall brightness, sort of a golden-green in RTHU, compared with 
gray-green in a BCHU. Not also the shorter, straighter bill, bright 
green forehead, and black border (almost a mask) between the throat and 
green of the head. It's hard to see in these pictures, but the wing is 
pointy, not paddle shaped as in a BCHU, the tail is more forked.

Birders are welcome to look, provided they notify me in advance. As with 
all migrants, I make no guarantees it will stick around.

Respectfully,

Duane Nelson

Las Animas, CO

Subject: Bird Conservancy Banding Report - Barr Lake Station, 9/25/16
From: meredith.mcburney AT birdconservancy.org
Date: Sun, 25 Sep 2016 15:55:14 -0700 (PDT)
A very slow morning for birds at Barr - We spent most of our time replacing 
nets destroyed by marauding Bambis (lost 5 this morning). 

We did catch our first of the season (and likely only) Blue Jay, our 4th 
Cassin's Vireo, and a few others.  Here's the breakdown:

Cassin's Vireo 1
Blue Jay 1
Ruby-crowned Kinglet 1
Hermit Thrush 3
Orange-crowned Warbler 2
Yellow-rumped Warbler, Audubon's 1
Dark-eyed Junco, Oregon 2

First morning all season that we have not banded a Wilson's.

WE ARE CLOSED TOMORROW, MONDAY. We are open 6 days each week, weather 
permitting, through October 16.We are closed every Monday in September, 
then October 4 and 12. We are opening nets at about 6:30 a.m. and we start 
closing between 11 a.m. and 12 noon. 
We will open later and/or close earlier if it is very hot, very cold, wet, 
windy, etc. There are school groups most weekday mornings, usually arriving 
around 9:30. Best times to visit, if you like lots of birds and fewer 
humans, are early mornings during the week and Sundays.

Subject: Broad-winged Hawk and Bird Conservancy Banding at Chico Basin Ranch Update 9/25/16
From: lmkoitsch AT gmail.com
Date: Sun, 25 Sep 2016 14:49:00 -0700 (PDT)
Hiya!

Today's first net round yielded a young female Broad-winged Hawk, a bird 
that had only been banded once before now and that was all the way back in 
2002. So, another pretty exciting morning here at Chico Basin Ranch!! 

Other than that early morning excitement, it was pretty slow and we banded 
less than a dozen birds before the winds kicked up and we were closed by 
10am. 

This is the final week for banding here at Chico Basin Ranch, so please 
stop by if you're in the area.

Subject: Birds at Baseline Reservoir
From: Jeff Parks <lastimout AT gmail.com>
Date: Sun, 25 Sep 2016 10:46:54 -0700 (PDT)
Hi all -

I went out to Baseline Reservoir outside of Boulder this morning to see if 
the Sabine's Gull was still hanging around, and to see what else was out 
there as well.  The gull was still hanging around the north end of the 
reservoir, moving around from time to time.  There was a Common Loon as 
well, reported a couple of days ago, it was on the southeast part of the 
reservoir diving for food.  While I was on Cherryvale watching the loon, I 
saw Sabine's Gull  down on the south end for a short time, but decided to 
head back to a safer spot when an Osprey started circling above it.  I was 
watching the Osprey to see if it would dive for a fish, and when I went to 
look at the gull again, it had disappeared, presumably back to the north 
end of the reservoir.  

While I was on the north end watching the gull, there was a fairly good 
sized flock of White-Tailed Swifts flying around over the north end of the 
reservoir and the hillside above that.  Ted Floyd was there for a short 
time as well, and he thought they had come from the northwest and were 
moving to the southeast.  It was kink of unusual to see such a large flock 
of swifts out this far from the mountains, but we enjoyed watching them 
anyway.  

There were a few other birds of interest, some Common Mergansers and a 
handful of Western Grebes as well as some Northern Shovelers and a raft of 
coot.

Good Birding -

Boulder, CO

Subject: Sabine's Gull continues at Chatfield SP sandspit, Douglas County
From: Douglas Kibbe <Dpkibbe AT msn.com>
Date: Sun, 25 Sep 2016 16:48:45 +0000
The juvenile Sabine's Gull present yesterday at Chatfield State Park was still 
present this morning. 


The bird alternates between sitting on the end of the sand spit and actively 
foraging between the spit and Plum Creek delta, potentially presenting good 
photographic opportunities for a patient photographer. 



A Long-billed Dowitcher was photographed this morning on the South Platte delta 
(Jefferson County). I saw the photo but did not refind the bird.

Subject: Bird Conservancy Banding Report - Barr Lake Station, 9/24/16
From: meredith.mcburney AT birdconservancy.org
Date: Sat, 24 Sep 2016 17:17:48 -0700 (PDT)
The days we love - enough birds to stay busy, at least one really cool 
thing, and good company to share it with!  No formal groups today, but lots 
of bird enthusiasts dropped by, many staying most of the morning, including 
Hugh and Urling Kingery, sharing their expertise and enthusiasm.  I was 
short one volunteer due to illness, but no matter - Hugh Kingery and Don 
Beltz, veteran recorders from years back, stepped in.  38 new birds plus 1 
return from last year.  The really cool was a Hairy Woodpecker, caught in 
the same run as a Downy.  Great comparison/contrast!  Plus Hugh noted that 
the Hairy had more white on its back and wing coverts, suggesting a more 
Eastern bird, while the Downy was more black, the sign of a Western bird.

Here's the breakdown for the morning:

Downy Woodpecker 1
Hairy Woodpecker 1
Black-capped Chickadee 1, banded 2015
Hermit Thrush 1
Orange-crowned  Warbler 6
Yellow-rumped Warbler, Audubon's 3
Wilson's Warbler 18
Chipping Sparrow 7
Song Sparrow 1

We are open 6 days each week, weather permitting, through October 16.We are 
closed every Monday in September, then October 4 and 12. We are opening 
nets at about 6:30 a.m. and we start closing between 11 a.m. and 12 noon. 
We will open later and/or close earlier if it is very hot, very cold, wet, 
windy, etc. There are school groups most weekday mornings, usually arriving 
around 9:30. Best times to visit, if you like lots of birds and fewer 
humans, are early mornings during the week and Sundays.

Subject: Williamson's Sapsucker in Bent County
From: Duane Nelson <dnelson1 AT centurytel.net>
Date: Sat, 24 Sep 2016 13:37:49 -0600
Hello birders,

At the tail end of our /National Public Lands Day/ work project to 
create nesting habitat for Piping Plovers and Least Terns in 2017, part 
of the group met at the shelter house at the entry to Corps HQ below the 
dam. This is south of the Hasty Bridge on the west side of the road. In 
the scattered trees, I located a male Williamson's Sapsucker, which 
seemed to prefer the two or three scattered juniper trees just east of 
the shelter house, but also spent time in the small elm trees present. 
Williamson's Sapsuckers are casual fall migrants on the eastern plains 
of Colorado, and I think this is a Bent County first. This is outside of 
the locked fence surrounding the main buildings, and birder access would 
be OK, even on weekends.

Where, may I ask, did you see the owl? In the trees by the houses or more 
towards the park? 


Thanks,

Birders in CO,
This morning in El Paso County I hit Sondermann Park for three hours. 
Birding was slow until about 10:00, when I noticed a few empids, some 
flocks of Wilson's Warblers, and a nice sized flock of Orange-crowned 
Warblers. An adult *Tennessee Warbler* was gleaning the willows in with the 
OCWAs. A *Juniper Titmouse* was also a surprise calling in the sagebrush 
hillsides. On my way back from Sondermann, I stopped at the Colorado 
Springs Xeriscape Gardens and Utilities area, and noticed flyovers *American 
Pipit *and *Broad-winged Hawk*. Hanging around the inner parking lot were 
two female Broad-tailed and a Black-chinned Hummingbird, as well as about 4 
*Dusky 

Flycatchers* and an adult male *Williamson's Sapsucker. *I was surprised to 
have so much migration activity between 10:00 and 12:00.

Go Birding,
David Tonnessen

Subject: Northern Saw-whet Owl Banded at Bird Conservancy's Chico Basin Ranch Banding Station 9/24/16
From: lmkoitsch AT gmail.com
Date: Sat, 24 Sep 2016 12:01:53 -0700 (PDT)


 



Hiya!


Well, I knew that the winds were pretty strong last night, but I still 
never expected to find a Northern Saw-whet Owl on the first net round! This 
young female was the first to ever be banded at Chico Basin Ranch (fee 
area) since Bird Conservancy started their migratory monitoring here in 
2002. 

Another slow day otherwise; after two hours with no birds and with the 
winds picking up again, we closed at 1030. Of course, it's pretty hard to 
top an owl, a hawk, and a bat in your first net round. :)

Tonight is supposed to be another night of strong northerly winds, so 
tomorrow might be another interesting day for birds! Of course, with the 
forecast calling for the strong winds to continue through the day tomorrow, 
banding might be cancelled.

Subject: CSR, El Paso Co, Saturday
From: Steven Brown <sbrown37 AT gmail.com>
Date: Sat, 24 Sep 2016 11:31:33 -0600
Hey COBirders,

The wind did bring in some new birds this morning for banding at Clear Spring 
Ranch, but nothing unique. What was unusual was catching many species that I 
thought were gone for the season, having not seen them for 7-10 days. Among the 
catch for today a Hatch-year Dusky Flycatcher, a HY F Lazuli Bunting (last one 
9/15), a HY Savannah Sparrow (last one 9/14), a HY Vesper Sparrow (last one 
9/10), an adult F MacGillivray’s Warbler (last one 9/18), and a recap (from 
8/25) Yellow-breasted Chat (last one 9/16). 


A couple of seasonal milestones - today I banded Chipping Sparrow #900 ! (only 
about 800 more than any other year!). Of those, about 175 were adults, for 
about a 5:1 ratio of adults to juvs. I have 1875 total birds for the season 
(previous high count - 525 in 2015, through 10/31!) It has been an exceptional 
year. Almost every species I catch has much higher numbers than any previous 
fall. The oats across the road were finally mowed, and 12” of stubble left in 
place, but there are very few birds coming out of the field anymore. Why are 
there so many more birds at CSR than in other years? You got me - I’m just 
recording the phenomenon! 


Oh, and I’m not done. I plan to be out there for another month.

more soon,
Steve Brown

While eating lunch, I saw your post, and stopped out there about 1:40 or 
so.  Saw several gulls out on the water, but no sign of this one.  I looked 
up and down the shore, it was standing on the sand fairly close to me just 
across the street from Stearns.  Got a couple minutes of good looks, the 
black bill is distinctive.  I haven't seen one before, It would have taken 
me awhile to figure it out for what it is.  I snapped a couple of quick 
pictures for ID purposes, one is attached.  As I watched it, it headed out 
into the reservoir, and then finally flew towards the south end of the 
res.  It landed on the water, but I didn't watch it much after that.  

Also saw a few Western Grebes, a little flock of Ruddy Duck, and some 
Common Mergansers. No sign of a loon, other than the one standing on the 
shore with binoculars (as my wife always says!).  

Happy Birding -

This morning my brother and I studied at least five Sterna terns at Boyd Lake 
SP (fee) without coming to a firm conclusion on their identification. They were 
mainly in the north end of the lake frequently sitting on a newly emerged 
sandbar.

West Fort Collins has been fairly quiet the past several weeks.  This
morning along the bike path leading out of Spring Canyon Park to the
north there was a nice, active flock of Yellow-rumped Warblers, with a
couple of Wilson's Warblers and an Orange-crowned Warbler or two.  I also
found (and photographed, two attached) a Blackpoll Warbler.

Also nearby was a Long-eared Owl, hunkered down for the day.

Not much competition for all the Sabine's Gulls being seen in northern CO, but 
today(930-945AM) at least 1 Sabine's Gull finally showed in southern CO at Lake 
Beckwith, Colorado City, SW Pueblo County. It was not seen after 945AM, but 
with unsettled cooler weather expected this weekend, Pueblo Reservoir, Lathrop 
State Park, & other large lakes might be worth checking. 



Other Colorado City birds of interest:


2 Golden Eagles regularly on Graneros Ave atop poles 1 mile west of I-25, exit 
71. 


1 Ferruginous Hawk today at Scroggs Canyon, NE of Craver Middle School, 
Colorado City 


1 Gray Flycatcher today at Scroggs Canyon;  present for past 2 weeks

1 Brewer's Sparrow today at Scroggs Canyon

Subject: Bird Conservancy Banding Report - Barr Lake Station, 9/22/16
From: meredith.mcburney AT birdconservancy.org
Date: Thu, 22 Sep 2016 20:55:05 -0700 (PDT)
Never know what will happen......It was cool and foggy early this morning 
and we weren't catching much; we were debating whether the fog was becoming 
mist and whether closing was in order. Then things cleared a bit, and the 
next run was a good one - caught a Cassin's Vireo and a Blue-headed Vireo 
almost side by side.  We also had a Green-tailed Towhee and a Spotted 
Towhee at the same time, making for 2 great photo ops in one morning.  And 
a Nashville Warbler.  And our first two Catbirds of the season.  All in 
all, a great morning, with 37 new birds of 16 species, plus 2 Chickadees 
banded last year:

Cassin's Vireo 1
Blue-headed Vireo 1 (First and perhaps only of season)
Black-capped Chickadee 2, both banded in 2015
House Wren 3
Hermit Thrush 2
Gray Catbird 2 (FOS)
Orange-crowned Warbler 6
Nashville Warbler 1 (FIrst and likely only of season)
Yellow-rumped Warbler, Audubon's 2
Townsend's Warbler 1
Common Yellowthroat 1
Wilson's Warbler 8
Green-tailed Towhee 2
Spotted Towhee 1 (FOS)
Chipping Sparrow 3
Lincoln's Sparrow 2
White-crowned Sparrow, Gambel's 1

We are open 6 days each week, weather permitting, through October 16.We are 
closed every Monday in September, then October 4 and 12. We are opening 
nets at about 6:30 a.m. and we start closing between 11 a.m. and 12 noon. 
We will open later and/or close earlier if it is very hot, very cold, wet, 
windy, etc. There are school groups most weekday mornings, usually arriving 
around 9:30. Best times to visit, if you like lots of birds and fewer 
humans, are early mornings during the week and Sundays.

Buckley Road end.  A nice walk before work.

Love the photos. I have the birding "bug" and I'm not sure how far down the 
rabbit hole I want to go. This is one tick in the need more photo equipment 
category.

Hi Gary, 
   I recently completed a research project that looked at the prevalence of 
rock wrens out on the plains. The results showed a significant cluster of 
rock wren vagrants near the Republican and Smoky Hill Rivers. (Further east 
than Nunn, but interesting nonetheless. I will post the link, but I don't 
think that this format will allow me to attach the article. I am happy to 
email a PDF of the article via e-mail (natwarning AT gmail.com) to anyone who 
would like a copy.    

Best Regards,   Nat Warning

I made a quick run out to Jumbo this evening and got better looks at the 
Jaegers this time.  I was able to identify all 3 as adult PARASITIC JAEGERS.

Other highlights included a Common Loon and at least 4 Sabine's Gulls (1 
adult, 3 juveniles), probably more.

Jumbo is a busy and exciting place, with birds moving around a lot.

Hey COBirders,

It has been pretty quiet banding at Clear Spring Ranch this week - several 
warblers and sparrows before 7:15, then pretty much dead for the rest of the 
morning. Today I caught and banded a Hatch Year Least Flycatcher (FOS) at 7:15, 
then it went dead again, ….until another large flock of Chipping Sparrows 
arrived about 9:30. 


39 birds banded today, with 30 CHSP, 2 Wilson’s, 2 Orange-crowneds, a 
Lincoln’s, a Catbird, and the LEFL, et. al. 


Maybe tomorrow….

Subject: Bird Conservancy Banding Report - Barr Lake Station, 9/21/16
From: meredith.mcburney AT birdconservancy.org
Date: Wed, 21 Sep 2016 15:33:53 -0700 (PDT)
Another day like yesterday - a good number of birds, led by Wilson's. 
 Despite the threat of heat, the cloud cover kept things comfortable and we 
were able to band through most of the morning.  We started with lots of 
recaps (birds banded earlier this season, a total of 33), then moved on to 
newly arrived Wilson's and Orange-crowned, then caught 4 Audubon's Warblers 
on our last run.  We are pleased to see that, unlike earlier in the season, 
our current recaps are showing significant amounts of fat.....a sign they 
are finding plenty to eat and getting the energy they need to continue 
their journey.  Here's the breakdown of the 48 new birds:

Downy Woodpecker 1
House Wren 2
Ruby-crowned Kinglet 3
Hermit Thrush 2
Orange-crowned Warbler 7
Yellow-rumped Warbler, Audubon's 4
Wilson's Warbler 28
Chipping Sparrow 1

We are open 6 days each week, weather permitting, through October 16.We are 
closed every Monday in September, then October 4 and 12. We are opening 
nets at about 6:30 a.m. and we start closing between 11 a.m. and 12 noon. 
We will open later and/or close earlier if it is very hot, very cold, wet, 
windy, etc. There are school groups most weekday mornings, usually arriving 
around 9:30. Best times to visit, if you like lots of birds and fewer 
humans, are early mornings during the week and Sundays.

From: DAVID A LEATHERMAN <daleatherman AT msn.com>
Date: Wed, 21 Sep 2016 22:18:52 +0000
Crow Valley Campground was much birdier today than the last few times I've been 
there but still nothing mega-rare. Pat and Vanna, I'd like to buy an eastern 
warbler. Best birds were at least 4 Broad-winged Hawks, Red-eyed Vireo, 
Tennessee Warbler, Merlin, Blue-gray Gnatcatcher and two Red-naped Sapsuckers. 
Several Western Tanagers, Ruby-crowned Kinglets, Hermit Thrushes, White-crowned 
Sparrows, Lincoln's Sparrows and Townsend's Solitaires. Thought I might have 
heard White-throated Sparrow. About 20 Wilson's Warblers. No empids. 



Many birds were feeding on sod webworm moths, presumably the Vagabond Crampus 
that has been in the news of late. The lingering water puddles in the creek 
channel in the Group Area and to the northeast seem to have the most bird 
activity. Tons of robins. 



Total of 47 species, almost all of them before it got hot (i.e. 8-10am).


A&B#1 Res on Weld CR124 about 1m w of CR77 still has lots of birds. None were 
unusual that I could see. About 7 Long-billed Dowitchers, few Least Sandpipers, 
lots of yellowlegs, few avocets. 



I checked Timnath Res (Larimer) on the way home and could find nothing unusual. 
FYI, roads are blocked from the east. Only way in is from the west, either 
coming south from east of FC on Prospect or north from downtown Timnath. Lots 
of construction equipment working on the south shore "beach" west of the dam. 
Birds don't seem to care, at least for now.

Subject: Golden Eagle Attack Ptarmigan
From: mvjohnski AT gmail.com
Date: Wed, 21 Sep 2016 09:02:35 -0700 (PDT)
I was hiking in the San Juan Mountains recently and doing photography of 
Ptarmigan (Mineral County) when out of nowhere came a Golden Eagle 
streaking down upon about 20 or so Ptarmigan, scattering the birds in all 
directions. This was only 40 feet in front of me and as the eagle seemed so 
focused on the quarry, he completely missed seeing me. It was a chaotic few 
seconds as the eagle flapped and maneuvered in front of me and then flew 
away without catching any lunch. All I could manage was partial photos of 
the rapidly moving, close bird. Anyway, quite the adventure. It was an 
immature eagle.

Speaking of low elevation Clark's Nutcrackers, I had a group of 6 of them
fly overhead, downhill no less, at White Ranch Open Space in Jefferson
County, on Sunday morning while I was trail running. I was probably around
6400 ft at the time, still in pondo land.

Ann Troth and I were also thrilled to find the Parasitic Jaeger still chasing 
gulls at Cherry Creek this morning. Thanks Glenn for finding this amazing bird. 


Ann and I just got back from a houseboating/kayaking trip to Lake Powell. We 
also had a Parasitic Jaeger on Powell about 40 miles up river from Bullfrog. 
That is in SW Utah. So it does seem to be a good year for the species.

Subject: Bird Conservancy Banding at Chico Basin Ranch update 9/20/16
From: lmkoitsch AT gmail.com
Date: Tue, 20 Sep 2016 15:05:48 -0700 (PDT)
Hiya!

Today we banded our 900th bird for the fall banding season here at Chico 
Basin Ranch (fee area). It was a *Blue Jay*! Haha now I know some of you 
were thinking that it might be a *Brown Thrasher* as we have managed to 
catch more of them than I, at least, ever thought possible. In fact, we're 
up to 48 newly banded Brown Thrashers this season, but who's counting. ;)

Another highlight today was a stunning *White-eyed Vireo*, a bird that we 
have not banded here in the fall since 2012. This was the second vireo 
that's usually considered a more 'eastern' bird, the first being the* 
Bell's Vireo*, that we've caught and banded this season. And after the 
*Prothonotary 

Warbler*....and the* Canada Warbler*....and the *Magnolia Warbler*, you'd 
think we'd run out of awesome birds down here at the Ranch, but you just 
never know what's going to turn up next! 

Also of note, we banded two more *Cooper's Hawks* today, bringing our total 
count for accipiters this season up to four. 

We're open every day through October 1st. Please note that this week there 
are large school groups scheduled on Thursday, Friday, and Saturday. 

Hope to see you out on the Ranch!

I was happy to see that the Parasitic Jaeger is still at Cherry Creek SP this 
morning at least from about 9:00 to 10:30 a.m. From a long distance, it looks 
pretty plain to my old eyes, until it flashes its wings. Then cool.

The Parasitic Jagger was still at Cherry Creek State Park this morning. Jamie 
Simo and I observed it from several vantage points today from about 10 am - 12. 
It mostly hung out in the middle of the lake though flew around hassling Gulls 
a few times.

Great photos Glenn, better then the ones I got at Chatfield. Now I see a 
posting that three have been seen at Jumbo, so maybe the one I saw was 
different and we are having a "jaeger invasion"? That would be awesome. Here I 
am planing a trip to 

 San Diego and the Imperil Valley this December and I was hoping to see my 
first Jaeger there in California, I have now seen my first in land locked 
Colorado! Amazing. Truly the joys of birding, you just don't know what will 
show up.

20 September 2016
Mostly cloudy day, fairly cool

On Sunday there were multiple harriers along the trail, today none.  I did 
see Red-tailed Hawks and a Cooper's Hawk to make up for it.  For sparrows, 
the other day it was almost all Vesper's.  Today, there were just two of 
those, but I had White-crowned, Clay-colored, Lark, Lincoln's Song and 
Chipping.  The only warblers were Wilson's and Orange-crowned (just one). 
 Everything else was the usual birds except for a nice Gray Catbird 
skulking about towards the Buckley Road end.  A nice walk before work.

Subject: Upcoming CFO Field Trip
From: William H Kaempfer <William.Kaempfer AT Colorado.EDU>
Date: Tue, 20 Sep 2016 17:10:33 +0000
CFO Members,

Here is an upcoming CFO Trip that might be of interest to you:

Sprague's, Le Conte's, and more
Yuma County and beyond - Saturday, Oct 8, 2016 6:00 AM - Sunday, Oct 9, 2016 
9:00 PM 

SAVE THE DATE! This trip is timed so as to maximize our chances for two 
Colorado desiderata: Sprague's Pipit and Le Conte's Sparrow. We'll start at the 
Fox Ranch for the sparrows, then inch ever closer to Kansas for the pipits. 


Limit 12 participants; CFO members only.


Here are additional details for this trip.


1. The trip is limited to 12 CFO member participants and 3 cars. I will 
organize all participants into shared rides once we have the participants. The 
three cars on the trip will then meet at a designated spot early on Saturday, 
October 8th to proceed out east for some great birding. 




2. Our destinations will include the private Fox Ranch (TNC) where we will 
explore for sparrows and other migrants including a reasonable shot for a 
glimpse of Le Conte’s Sparrow. Then on to the Hale area to try for 
Sprague’s Pipits at “Pipit Hill”. Finally we will continue to Wray where 
we will spend Saturday night. As time permits in Wray we will visit Stalker 
Pond, the Fish Hatchery and some or the surrounding sand sage country. 




3. My plan is to stay that night at the Cobblestone Inn in Wray and enjoy 
dinner at 4th and Main, a fun place for a group dinner in the heart of downtown 
Wray (so to speak). 




4. Sunday we will depart as soon as the breakfast schedule allows us and head 
into….Nebraska! I have come to love a couple of spots in SW Nebraska—Rock 
Creek State Recreation Area and Rock Creek State Fish Hatchery and I think you 
will find the birding great there, too. I hope not to jinx anything, but I 
suspect all of the participants from last year’s trip are still thinking 
about the 55 Greater Prairie Chickens that flushed across the road right in 
front of us (flushed by a Northern Harrier, not by us, I should add). 




5. From the Rock Creek area we will work our way back home with stops dictated 
by recent sightings. 



If you are interested in joining John Vanderpoel, my co-leader, and me, please 
reply by email.

The late summer draw down has left a large mudflat on the west side. Didn't
have time to stop but looks promising. Be careful of traffic.

It's on Nelson Road west of 75th in Boulder County.

Subject: Marston Res -- Common Loon and Sabine's Gull
From: Chris Rurik <chrisrurik AT gmail.com>
Date: Mon, 19 Sep 2016 20:42:39 -0700 (PDT)
Hi all --

I birded Marston from all vantage points around noon today. Heat shimmer 
wasn't much of an issue. The biggest challenge other than the usual Marston 
challenge of standing in awkward places and looking through a chainlink 
fence (see the Colorado County Birding website for instructions on how to 
bird Marston) was learning not to get excited about the dorsal fins of 
carp. They would appear, wave around in circles, then disappear -- kind of 
otherworldly but also pretty annoying in my search for phalaropes.

Bird numbers have been marginal at best at Marston all year. I only saw 
about six Western Grebes today and no shorebirds other than Killdeer (no 
phalaropes). A nice loafing party of American White Pelicans, Ring-billed 
and California Gulls on the west side. One flotilla of ten American Coots 
was visible from every vantage. A party of seven Common Mergansers appeared 
on the east side and went arrowing after something or other.

I saw the previously reported Common Loon within minutes of arriving at the 
west side. It cruised past, close in to shore, peering underwater in the 
loon way, then disappeared for the rest of the nearly two hours I spent 
repeatedly scanning, scanning, scanning, repeating.

I almost didn't make the final stop along Bow Mar Drive. Good thing I did: 
on my second scan I caught a small gull flying out toward the middle of the 
lake. It was a Sabine's, possibly the one reported yesterday. It flew for 
fifteen seconds (majestically) then landed in the middle of the res and 
floated. Distant even with the scope. An awesome bird.

Good birding to all,
Chris Rurik
Denver CO

Subject: Clark's Nutcrackers (low el.) BW Hawk, Boulder 9/16
From: Thomas Heinrich <teheinrich AT gmail.com>
Date: Mon, 19 Sep 2016 11:00:51 -0600
Hi all,
Friday morning I had caught a brief flyby and stopover of three Clark's 
Nutcrackers moving south to north along the Dakota Ridge (approx 5800') at the 
base of Mt. Sanitas (a new yard bird). 


Sunday morning (9/18) I had a light Broad-winged Hawk rising in the developing 
thermals above my yard. Seemed like it had roosted very close Sat night. 


Good birding,

Subject: Fwd: Colorado Osprey Tracking - September 19
From: Jason Beason <aeronautes.saxatalis AT gmail.com>
Date: Mon, 19 Sep 2016 10:27:06 -0600
Greetings,

We are tracking an Osprey from her nest site near the Grand Lake area. We
named her Shadow because her nest was on the shore of Shadow Mountain
Reservoir. We also tracked her in 2013 but the satellite tracking device
fell off just before 2014 spring migration. We were happy to recapture her
again in June of 2016 and see that she is doing fine and now we have
tracked her south to her wintering site again.

We received location fixes for Shadow through noon on September 17th this
morning. She seems happy at Laguna Madre and has moved little since last
report on the 14th.

For fun I added Shadow's location fixes from late September through October
2013 to the map so you can see where she spent time that fall. Many
migration research projects show that birds are faithful to their breeding
sites and also wintering sites as long as the habitat they require remains.

Subject: Bird Conservancy Banding at Chico Basin Ranch Update 9/18/16
From: lmkoitsch AT gmail.com
Date: Sun, 18 Sep 2016 18:09:04 -0700 (PDT)
Hiya!

Things are starting to heat up down here at Chico Basin Ranch (fee area) 
and unfortunately, I don't mean with migration! Temps peaked around 88F 
today and are predicted to go over 90F the next two days. Sadly, the 
combination of high temps and clear skies are not the best for either 
banding or birding as it was almost eerily quiet and still for most of the 
day. Despite the weather, we were still fortunate to band 40 new birds, 
including three 'first of the season' species: *Sharp-shinned Hawk*, *Blue-gray 

Gnatcatcher*, and *Rock Wren*! 

What I find interesting is that every day for the last four days, albeit at 
different times, a flock of *Common Grackles* and *Red-winged Blackbirds* 
make a very noisy appearance/entrance into Holmes Grove, which in turn, 
usually heralds a flurry of activity from other various sized birds as 
well. This is actually proving to be not only the best time to catch birds 
but also to see them. There is a group of four* Red-shafted Flickers* that 
almost always add their own 'antics' to the blackbird commotion in the 
grove and we have now caught all four of them, although only banded three, 
as the female keeps freeing herself from the nets. 

Also, of note, the *Long-eared Owls* made their first appearance today in 
the back area of Holmes Grove where they like to roost in the winter. They 
had been seen elsewhere on the ranch but today was the first day that they 
were spotted by Holmes. The *Prothonotary Warbler *was not seen today nor 
was it recaptured, although he had a decent amount of fat on him both times 
that we caught him so hopefully he has found his way back on track.  

As of today, we have banded 848 new birds and 52 species this fall.  

We will be open every day until October 1st. Please not that this week 
there are large school groups on Thursday, Friday, and Saturday and they 
usually start around 9/9:30. 

Hope to see you out on the ranch!

Subject: Bird Conservancy Banding Report - Barr Lake Station, 9/18/16
From: meredith.mcburney AT birdconservancy.org
Date: Sun, 18 Sep 2016 17:06:24 -0700 (PDT)
When our first run of the morning consisted of 5 recaps and only 1 new 
bird, we knew we were likely in for a slow day.  Apparently little moved in 
over the past 24 hours.  The weather was cool to start, but heated up 
quickly, and we did an early close.  Total new birds for the day was 14 (we 
had 15 recaps):

House Wren 1
Orange-crowned Warbler 4
Wilson's Warbler 9

WE ARE CLOSED TOMORROW - MONDAY.  We are open 6 days each week, weather 
permitting, through October 16.We are closed every Monday in September, 
then October 4 and 12. We are opening nets at about 6:30 a.m. and we start 
closing between 11 a.m. and 12 noon. 
We will open later and/or close earlier if it is very hot, very cold, wet, 
windy, etc. There are school groups most weekday mornings, usually arriving 
around 9:30. Best times to visit, if you like lots of birds and fewer 
humans, are early mornings during the week and Sundays.

The Parasitic Jagger was still at Cherry Creek State Park this morning. Jamie 
Simo and I observed it from several vantage points today from about 10 am - 12. 
It mostly hung out in the middle of the lake though flew around hassling Gulls 
a few times.

Great photos Glenn, better then the ones I got at Chatfield. Now I see a 
posting that three have been seen at Jumbo, so maybe the one I saw was 
different and we are having a "jaeger invasion"? That would be awesome. Here I 
am planing a trip to San Diego and the Imperil Valley this December and I was 
hoping to see my first Jaeger there in California, I have now seen my first in 
land locked Colorado! Amazing. Truly the joys of birding, you just don't know 
what will show up.

Subject: Chatfield 9/16 and Ken Caryl Valley 9/17
From: David Suddjian <dsuddjian AT gmail.com>
Date: Sat, 17 Sep 2016 22:13:31 -0600
Yesterday I spent a short time at Chatfield SP early in the morning,
without finding too much of note. The best for me for the park was a
female *Williamson's
Sapscuker* along the path leading to the Original Heronry Overlook
platform. She flew into some pines there, then after a short time flew out
toward some other trees nearer to the park office. A juv. *Sabine's Gull*
was over the lake off the South Platte delta.

In the last few days Migrant landbirds around my home at Massey Draw in Ken
Caryl Valley have been moderately diverse, but in lesser numbers than on
some of the better recent days. Highlights from the yard perspective
include *Green-tailed Towhee*, *Sage Thrasher* and *Rock Wren*.
*Hummingbird* numbers are thinning notably, *House Wrens* and *flycatchers *are
dropping out. *Wilson's Warblers* remain relatively numerous, but *Yellows*
and *MacGillivray's* are winking out, while *Audubon's* and *Orange-crowned
Warblers *and *Ruby-crowned Kinglets* are increasing. *Townsend's
Solitaires* and *Mountain Bluebirds*, too.

My front porch looks toward the first rise of foothills that is inside the
hogbacks. This morning I spent some time scoping above the upper slopes
there, perhaps leaving my neighbors a little uncertain as I pointed my
scope over and beyond the tops of their homes. And it paid off, as there
was a decent movement of raptors, mostly moving south. I viewed in three
periods from 9:30 to 12:15 totalling 105 minutes. The raptor talley
included 4 *Turkey Vultures*, 12 *Sharp-shinned Hawks*, 7 *Cooper's Hawks*,
11 *Accipiter sp.*, 9 *Red-tailed Hawks*, 1 *Buteo sp.*, 2 *Golden Eagles*,
14 *American Kestrels*, 1 *Merlin*, and 2 *falcon sp*.  I also saw one *Lewis's
Woodpecker* moving south. I was pretty happy with this for an effort from
the front porch!

I'm starting to look at my (low-quality) photos, and I still favor the ID 
we had in the field for Jaegers 1 and 2 at Jumbo:  Adult Parasitic.  I will 
upload some photos soon.

It appears I photographed Jaeger 3 earlier by accident while I was 
photographing another, not realizing yet that we were dealing with multiple 
Jaegers.  Photos of Jaeger 3 are more suggestive of Adult Pomarine, with 
really high contrast markings on the undersides including a dark vent.

I hope others will be able to enjoy these fascinating birds and help firm 
up the IDs.
