Hutton's Vireo, Vireo huttoni


Hutton's Vireo, 2/20/09, Rancho San Antonio
The Hutton's Vireo, a year-round resident of live oaks in the Bay Area,  closely resembles the Ruby-crowned Kinglet which is a common wintering bird here. The vireo differs in having a larger bill and spectacles rather than an eye-ring, and it lacks the black feathering below the second wingbar.
