Myrtle Warbler, Sawhill Ponds, Boulder County

[Paula Hansley]

Birders,

Here is a picture of one of the Myrtle Warblers that I saw this morning:

It was in a small flock of Yellow-rumped Warblers by Boulder Creek at dawn. There was one Audubon's Warbler in the flock.  Some of the warblers were softly singing despite the 33 degree temperature!
