Allen's Hummingbird
Selaphorus sasin
The upper left photo is of an Allen's Hummingbird seen in the Mendocino Coast Botanical Gardens in Mendocino, CA on June 18, 2014. It looks like it had a recent bath. The upper right photo was also taken close to the water at Cesar Chavez Park in Berkeley, CA on April 17, 2014. It shows a male Allen's Hummingbird with green upper back turning rufous toward the rump and a strong throat gorget. The lower left photo also shows an Allen's with the green upper back and rufous lower down; this individual was in my north Berkeley neighborhood and not near water.
