Wilson's Warbler

Wilson’s Warbler (Cardellina pusilla) is a small, yellow and green bird native to North America. The SF Bay Area is part of the Wilson’s Warbler’s winter range, and the Pacific coast populations even have the brightest foreheads and faces. Keep an eye on the trees in the springtime -- these birds have little fear of humans and often begin nesting in early March. Otherwise, you can often find them feeding on insects or foraging through shrubs.
