[cobirds] Bird Conservancy Banding Report - Chatfield, 5/11/19

[Meredith McBurney]

Not as busy as yesterday, but plenty to keep us going and lots of species.  
Best bird of the day was the first Yellow Warbler of the year that is on 
our longevity chart - 2560-93331 was banded as an adult in 2013, so he is 
at least 8 years old; we have caught him every year.  Here's the breakdown 
of today's 61 new birds:

Dusky Flycatcher 5
Hammond's Flycatcher 1
Black-capped Chickadee 2 new, 1 banded 2017
White-breasted Nuthatch 1
House Wren 1
Blue-gray Gnatcatcher 7 (One of many species that appears to have had a 
great year)
Hermit Thrush 1
Orange-crowned Warbler 3
Virginia's Warbler 2
Yellow Warbler 2 new, 1 banded 2013, 1 banded 2015
Yellow-rumped Warbler, Myrtle 4
Yellow-rumped Warbler, Audubon 22
Yellow-rumped Warbler, Intergrade 1
MacGillivray's Warbler 1
Common Yellowthroat 1
Spotted Towhee 1 new, 1 banded 2018
Lincoln's Sparrow 1
Bullock's Oriole 1 (FOS)

We will be open daily, WEATHER PERMITTING, through May 31, except for 
Memorial Day. We are opening nets at 6:30, and most days will have birds 
back at the station by 7:15. We aim to close by noon most days, earlier if 
it is very hot, very cold, or very windy. Registration is required for all 
weekend visitors; see the Denver Audubon website to sign up. Individuals 
may visit weekdays without registering before the school groups arrive, 
which is usually around 10 a.m. 

Come visit!

[cobirds] Boulder Mt Park and other

[JohnT]

CO-birders:
 For May 11th, Sat. -  mostly shrub-land areas along 
riparian corridors in Boulder Mountain Park.   All sightings are within 
Boulder County.  

Birds of special interest in CAPS

Key:

G = Gregory Canyon and feeder trails + lower Flagstaff Mt. Trail
SK = Skunk Creek and feeder trails
BC = Bear Creek and Bear Canyon trails
SAW = Sawhills \ Walden Ponds
LOU = Louisville

Birds of note:

Cooper's hawk - 4 - G, SK 
Turkey vulture - 6 - G
Red tailed hawk - 1 - SK
Great horned owl - 1 - BC - great horned owl nest site in Bear Canyon, 
previous site was a traditional prairie falcon nest site;  1 immature in 
nest site
Broad tailed hummingbird - 40+ -  G, SK, BC - all males, flight displays, 
chases
Say's phoebe - 1- BC
Plumbeous vireo - 1 - BC
Scrub jay - 1 - SK - lower skunk creek, traditional area to see scrub jays 
year round
Bushtit - 30+ - G, SK, BC - bushtits have become common throughout Boulder 
County year round
House wren - 15 - G, SK, BC - not in numbers as high as last year;  anyone 
else notice this?
Bluegray gnatcatcher - 16 - G, SK, BC - high concentrations at skunk creek
Gray catbird - 1 - SK
Orange crowned warbler - 6 - G, SK, BC - almost always associated with 
blooming wild plum.  Wild plum is already past peak bloom in most areas
Virginia's warbler - 4 - G, SK, BC
Audubon's warbler - 3 - SK, BC
MacGillivray's warbler - 7 - G, SK, BC - all males
Yellow warbler - 3 - SAW
OVENBIRD - 1 - BC - male singing;  traditional area up Bear Creek where the 
trail crosses over Bear Creek and heads uphill;  mixed evergreen and shrub 
habitat;  although not uncommon, its interesting to note 
   certain sections along the Mesa Trail have singing 
ovenbirds from mid-May through the 1st week in August.  
Yellow breasted chat - 8 - G, SK, BC
Spotted towhee - 55+ -  G, SK, BC - all males;  singing, chases, fights
Green tailed towhee - 1 - SK
Chipping sparrow - 100+  -  LOU - migratory flocks
Vesper sparrow - 10 - SK, LOU - mostly Louisville
Lazuli bunting - 6 - SK, BC
Bullock's oriole - 4 - G, SK - all males
Red crossbill - 15 - BC
Black headed grosbeak - 8 - G, SK, BC

Other notes:
Willet - 14 - in Louisville, flyover, Thursday evening
Snowy egret - 1 - Louisville - 1st time I've seen one in Louisville - 
Warembourg Pond
White faced ibis - 25 - Sawhills, flyover
Sora - 1 - Sawhills - calling

The funniest thing I saw today was a house wren attacking a MacGillivray's 
warbler.  Or maybe not so funny for the warbler.  

For Boulder data counts:  visuals on mule deer, raccoon, coyote, fox 
squirrel, pine squirrel, chipmunk ssp, black tailed prairie dog, eastern 
cottontail, bullsnake

Wildflower bloom seems slow and stunted this year, probably due to the 
weather, which is limiting the insects, which is limiting the birds (?).  A 
guess. I'm seeing less neo-tropicals this year compared to last year at the 
same time.  

Cheers,John Tumasonis (aka:  John T),  Louisville CO

Re: [cobirds] Revised RBA May 10: HOODED WARBLER in Crowley County, NOT Lamar CC

['Allison Hilf' via Colorado Birds]

Thx Sam - I already corrected it today when it was posted as “continued”.

I’m not sure why on Thursday it originally posted without your name (there was 
no name on report when I checked before I had gone to bed).  Perhaps e-bird 
made error, or you might want to check your settings and see if they are 
generally public?  It shows up now, but originally didn’t on Thur.

[cobirds] Wheat Ridge Greenbelt Warblers Jefferson Cty

[Tammy and Curt CAMPBELL]

Did a 4 hour loop today from the Youngfield parking lot sifting through 
Yellow-rumps the entire time.  North of Clear Creek about midway of West lake 
was a Black-throated Gray Warbler.  South of Prospect Park and the creek was 
another Black-throated and a Townsend's Warbler, both in the same small 
juniper.  On the southeast corner of West lake there was a Tennessee Warbler.  
From now on I'm always gonna carry a heavy camera with a dead battery, the only 
time I saw the Pink-footed Goose my battery was dead then too.

Yes all,Sam was the original reporter. I had it later in the day (unknown to me 
at the time that it had been seen). We had the bird again today on the FCRP May 
count. 
I certainly do not want any confusion!

Hey, 

I was the original reporter of the el paso county Great Crested Flycatcher. My 
ebird observation is still there and the bird was photographed, photos are on 
my checklist. If you look in the el paso county rarity alerts you can find it. 
Just letting you know so you can include the observation on the RBA!

[cobirds] Re: Possible Field Sparrow at North Shields Pond Natural Area, Fort Collins, Larimer county

Hey everyone,

I'm removing the word "possible" from this post and saying that it was, in 
fact, a Field Sparrow.
Here's the ebird list from this morning:

[cobirds] Mt Falcon - Jefferson County

[John Breitsch]

Since we are right smack in the middle of migration, and this is Spring 
Count weekend, I decided to be completely different and go to the foothills 
and see which breeders had returned.  I ended up with 41 species.  A 
partial list includes, Dusky Grouse, Wild Turkey, Common Poorwill, Canyon 
Wren, Evening Grosbeak, Black-headed Grosbeak, Western Tanager, Spotted and 
Green-tailed Towhees, Virginia's Warbler, and some Yellow-rumped Warblers.  

I walked the Tower Trail and came back on the Parmalee Trail.  DFO trip 
along the same route next week.

[cobirds] EASTERN TOWHEE, Tamarack SWA, Logan County

[cteuton]

This morning, Dan and I stopped by the west side of Tamarack SWA. We heard a 
towhee song that was not typical for Spotted Towhee. The singer was found high 
in the trees, and we identified him as an EASTERN TOWHEE by his song and wing 
pattern, which showed an absence of scapular spotting, with white primary 
bases. A couple of "back of the camera" shots are on the ebird list below.

https://ebird.org/view/checklist/S56131878

We also saw a male Blackpoll Warbler amongst many Myrtle type Yellow-rumps at 
Red Lion SWA (also in Logan county). The birds were feeding in weedy material 
wedged in the creek that crosses under the road there, and low in bushes/trees 
at the edge of the creek.

Re: [cobirds] Barr Lake Walk on 5/10 - PUMA and BEVI (Adams County)

['Andrews Robert' via Colorado Birds]

 
Hello all,

Congratulations to Cathy for the sighting of a female Purple Martin at Barr 
Lake. A great record and always a nice find in eastern Colorado. On April 29, 
1976, I saw a beautiful male Purple Martin along the east side of Barr Lake, on 
a cold, cloudy day and mixed in with hundreds of other swallows. I have not 
entered most of my old records into e-Bird, so it won’t show up there. I may 
have submitted the record to the CFO Records Committee, but I am not sure.

warbler front, with mostly only YRWA present. I did have one Northern 
Waterthrush along the stream below the dam. Best birds of the day were an 
exhausted looking female Purple Martin (first record for Barr Lake and possibly 
first Adams county record) - viewed perched about half way down between dock

flew towards fishing dock). I did not get a solid visual or any photo of the 
BEVI, but felt comfortable with what I heard and briefly saw and I am fairly

[cobirds] Fall out of Gray Flycatchers in Canon City Friday

[SeEttaM]

The socked in weather with rain and snow brought a lot of migrating Gray
Flycatchers down in Canon City.  I saw 25 of them during a one mile walk on
the Canon City Riverwalk.  A similar Gray Flycatcher fall out occurred
several years due to weather.  I got a couple of nice pics of Gray
Flycatchers which I have uploaded to my Birds and Nature blog
.
Fyi, I am especially proud of these as I am sporting a brace on my left
wrist due to a compound fracture 3 weeks ago which has challenged my
photography skills.
