Bay-breasted Warbler
Dendroica castanea
June 2 Pt. Reyes, Marin Co., Calif: 1 ♂ at lighthouse (where
present since at least yesterday). The flanks weren't as dark
bay as the breast and crown and weren't solidly-colored - probably
a first-yr bird. All field marks seen well at close range
as the bird foraged in bushes at eye-level in good light.
