5 Tundra Swans, Sombrero Marsh, Boulder County + Prairie Falcon

[Maureen Blackford]

Hello, 

 

At 10:30am on Monday 11/25, there were 5 Tundra Swans on Sombrero Marsh, Boulder County.   One was adult, with the yellow lores.   The other 4 didn't have the yellow, but had the same bill size, with the rounded border at the top of the bill, and curve at the gape.   (They look like the "1st Summer" pictures in Sibley's Guide.)    The pond is starting to ice up, so they swim back and forth at the southeast section of the pond.  

 

Sombrero Marsh is 1 block south of 63rd & Arapahoe in Boulder.

 

There was a prairie falcon (adult) sitting in the cottonwood tree over Naropa, at the northwest corner of 63rd & Arapahoe.
