Chestnut-sided Warbler, Boulder

[Nathan Pieplow]

Hi all,

This morning, an active flock of migrants at the west end of the Cottonwood Marsh boardwalk at Walden Ponds included a first-winter female Chestnut-sided Warbler, as well as a Green-tailed Towhee and a bunch of other more common species. The snipe count at the marsh was 88.
