I saw an active discussion on <eBird-alert...> concerning a reported sighting of a Costa’s Hummingbird in Alameda.
Back a week ago go took a photo at Meeker Slough next to some Pride of Medeira of a humming bird shown below. After looking at a lot of photos and consulting Sibley I can to the conclusion it was probably an Anna’s although in the photo, the gorget is somewhat unusual. Not dark purple though. Anyway, I am now curious what the expert view of this is. One thing is the Costa’s seem to have more white below the gorget.
