Saw this little one in Harmon Canyon. Would normally default to Anna’s female. But… is there any chance this is a female Costa’s? Sibley notes their tail is short with wings extending beyond. From many angles it looks mostly white on it chin and breast. The beak looks pretty straight though, and in Sibley it is drawn slightly curved downward. These West Coast Hummers look all the same when they aren’t adult males! – Dean

Looking at some pics online I would guess Anna’s. Although they are year around in your area, I bet they will become more abundant as summer gets closer. Not to say that isn’t a Costa’s though, just a guess! – David

I have not seen a Costa’s since I started birding, it would be a lifer for the competition! – David
