Townsend's Warbler
Dendroica townsendi
Townsend's Warblers can be observed in my neighborhood of north Berkeley, CA from fall through spring, like the one on the left side seen on Dec. 22, 2014. The Townsend's Warbler on the right was observed at Lake Anza in Tilden Regional Park, CA on Oct. 12, 2013. (Click on images to see enlarged versions.)
