[cobirds] Bird Conservancy Banding Report - Barr Lake Station, 9/24/16

[meredith . mcburney]

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.

Re: [cobirds] Common/Arctic Terns at Boyd Lake (Larimer)

[Nick Komar]

Today I returned to Boyd Lake with my brother Oliver and David Wade, using 
Dave's canoe to get better acquainted with the terns at the north end.  We were 
able to confirm 7 Common Terns.

[cobirds] Williamson's Sapsucker in Bent County

[Duane Nelson]

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.

[cobirds] Blackpoll Warbler, West Fort Collins, Larimer

[Adam Johnson]

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

Thanks,

[cobirds] Migration Movement

[David Tønnessen]

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

[cobirds] Northern Saw-whet Owl Banded at Bird Conservancy's Chico Basin Ranch Banding Station 9/24/16

[lmkoitsch]

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.

[cobirds] CSR, El Paso Co, Saturday

[Steven Brown]

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
