[cobirds] Philadelphia Vireos Barr Lake (Adams Co)

['Dan Stringer' via Colorado Birds]

Today Tom Whitten and I saw Philadelphia Vireos at Barr Lake in Adams 
County, in two different locations.
First one was on the trail that runs from the banding station east then 
north, on the west side of the small pond just off of the boardwalk to the 
viewing blind. A bright bird, tucked in deep in willows, working 4 to 5 
feet above ground.

Second one was no more than 100 yards from the boat ramp parking area going 
towards the banding station. Working low as well, mostly near the ground 
but went up and down. A drab bird, thus it took a bit of time to separate 
from Warbling, although it didn't look right for Warbling from the start. 
Even this paler bird had much more yellow underneath, especially throat and 
undertail coverts. This bird seemed smaller than Warbling overall, mostly 
due to a shorter tail, the head looked less angular, bill even seemed a bit 
smaller, but the most interesting thing separating it from Warbling was in 
addition to the prominent curved white line above the eye, it had small but 
quite noticeable white below the eye (dark lores making it stand out more).

[cobirds] Chico Basin Ranch Banding Report - Week 1

[Aaron Yappert]

Hey all,

The Bird Conservancy of the Rockies banding Station at Chico Basin Ranch has 
wrapped up its first week of banding and we've had some exciting captures. The 
cold front early in the week brought some good birds, but lately, with the warm 
weather, things have generally tapered off later in the day. 

Through 7 days of banding, we've banded 294 individuals of 40 species. 

Highlights: Calliope Hummingbird (1), Red-eyed Vireo (2), Ovenbird (3), 
Bewick's Wren (1), Nashville Warbler (1), and Virginia's Warbler (1). 

The station runs Monday through Saturday, 6:30 am till 12 noon. We love to 
share our birds with the public so feel free to come by. Please make sure to 
check in at the Ranch office before visiting the station. Lastly, be aware that 
the Ranch uses the station as an educational opportunity for a variety of 
school groups or other interested organizations so after 9 am the station may 
be filled with wide-eyed youngsters. 

Good birding,
Aaron Yappert
Volunteer Bander

Re: [cobirds] Montane Birds on the Move

[Peter Burke]

Hi Ted,
Thanks for sharing the NAB article. I'm curious if  the heavy smoke that
blanketed much of the northern Rockies might be partly or wholly to blame?
Are you aware of other instances where heavy smoke, without regional fires,
has generated species movement akin to the effects of other large weather
systems like, say, cat 5 hurricanes?

[cobirds] Bird Conservancy Banding Report - Barr Lake Station, 8/13/17

[Meredith . McBurney]

Slow, hot and weird morning.  There was a Chickadee convention going on in 
the area around the front nets as we made our first run - we caught 8 (1 
new, 6 banded earlier this year, 1 banded last year) and there were still 
many in the willows chickadee-ing.  We also caught a Brown Creeper (an 
unusual capture for us) and a first-of-season Brewer's Sparrow and a few 
Warblers and we thought we were starting a nice, interesting day.  But that 
was pretty much it for the morningOnly 9 new birds today:

Black-capped Chickadee 1 new, 1 banded last year
House Wren 2
Common Yellowthroat 1
Wilson's Warbler 2
Brown Creeper 1
Brewer's Sparrow 1

Maybe we need to put some nets up near the teepee where Ira et al found the 
Bunting and Thrashers!

Come visit! We are open 6 days per week (CLOSED Mondays), 
weather permitting, through October 15. We are opening nets at 6:30 and 
should have birds back at the station before 7:30. We will close most days 
by about 11:30, earlier now when it is so hot. School groups arrive most 
weekdays at about 9:30.

[cobirds] Caspian Terns - Timnath Res.

[marimammoser]

At 11:30 today, there were still two Caspian Terns on the sand spit to the 
north 
at Timnath Reservoir. They flew in as I was scanning the shore where the 
Gulls
and Pelicans and Cormorants roost.

[cobirds] Montane Birds on the Move

[Ted Floyd]

Hey, everybody. Here's coverage at The ABA Blog of the apparent ongoing 
irruption of montane bird species out onto the plains:

http://blog.aba.org/2017/09/happening-now-mountain-birds-on-the-move-but-how-extensively.html

Rank-and-file birders can contribute importantly to our understanding of 
what's going on.
