[cobirds] Bird Conservancy of the Rockies - Barr Lake Banding Report, 10/12/21

[Meredith McBurney]

Today was cool and we started with a net run that suggested it might be 
busier than usual.  But that optimism was short-lived, and we ended the day 
with 17 new birds:

Ruby-crowned Kinglet 2
Gray Catbird 2
Yellow-rumped Warbler 3 (1 Myrtle, 2 intermediates)
Song Sparrow 2
White-crowned Sparrow, Gambel's 8 (this species may come in at about normal 
levels.a seed eating, short-distance migrant)

This season, we increased the Barr banding season by 2 weeks (from 7 to 9) 
to make sure we included the late fall migrants.  So, last Sunday, which 
ended week 7, would normally have been the end of the season.  As of the 
end of Sunday, we had caught a total of 988 individual birds.  The average 
birds caught over the past 15 years is 1362, and 2020 (last year) was 
1939.  These are just raw numbers, not adjusted for number of hours/days 
the station was open, number of net hours, etc., but gives a rough sense of 
how sparse a season it has been.

We are open 6 days a week, weather permitting for about 2 more weeks.  
Closed Mondays.  Click here 
 to register to 
visit - we are offering one-hour slots (up to 12 visitors at a time); 
7:30-8:30 most weekdays, and 8-9, 9-10, and 10-11 on weekends.  Come 
visit!  Even with fewer birds than usual, it is a chance to get a good, 
up-close look at fall birds.

[cobirds] Boulder Audubon Meeting - Meteorological Musings on Migration

[Sydney Rayl]

*BCAS Meeting*
*How Did That Bird Get Here? Meteorological Musings on Migration*

*Join Boulder County Audubon Society and meteorologist Bryan Guarente on 
Tuesday, October 26, 2021* to learn about how the wind influences bird 
migration. You've found or chased vagrant, spring migrants in your many 
birding days on this planet. Those birds got here on the power of their own 
wings, fat reserves, hormones, and no doubt with the help of the wind. The 
relationship birds have with the wind is awe-inspiring. The physiological 
evolution from this relationship helps birds soar effortlessly while 
covering significant distances or float just above the water surface. 
Together with Bryan Guarente, let's take a look at some of those vagrant 
migrants and see how the weather tells us their intriguing migration story. 
We'll explore some of the more intriguing migrants over the past year and 
show you the wind patterns that likely brought them.

Bryan Guarente is a meteorologist and instructional designer who grew up 
birding with his father in southeast Pennsylvania. Bryan now works at the 
University Corporation for Atmospheric Research, training meteorologists on 
all things forecasting both nationally and internationally. He is excited 
to extend his work to help the birding community understand the 
relationship between weather and bird migration. *Visit our website* 

 to 
learn more!

*When*: Tuesday, October 26, 2021.  If the meeting is held in person, 
socializing starts at 7:00 PM with the presentation starting at 7:15 PM.

*Where*: The location of this meeting will be determined at a date closer 
to the event. It may be held online or in person. If held in person the 
location is the Unitarian Universalist Church of Boulder, 5001 Pennsylvania 
Avenue, off 55th St. between Arapahoe and Baseline. We will post location 
updates on the *event page on our website* 

!

*We hope to see you there!*

[cobirds] Gulls and Dowitchers/Weld

['The Nunn Guy' via Colorado Birds]

Hi all

On Sunday at Windsor Reservoir overlook had a "zillion" gulls loafing on 
the exposed bottoms-water is very low.

   - Lesser Black-backed Gull 5-7 all adults
   - Multiple Herring Gull
   - Multiple California Gull
   - Loads of Ring-billed Gull

At Cozzens Lake had about 30 Long-billed Dowitcher. 

Small flock of Greater Yellowlegs at CR 59 marsh. Loloff had dowitchers and 
yellowlegs.

Cozzens Lake had hunters in blind (NE corner of lake) as did CR 61/74 pond 
(south) in Galeton-no birds.

In the yard seven Common Grackle appeared all day-had not seen them in 
months.

Thanks, Gary Lefko, Nunn
