  Selas-4275c-72.jpg - Allen's/Rufous Hummingbird ( Selasphorus  sp.) in Claremont Canyon Regional Preserve on Apr. 21, 2015.  Photo taken by John Colbert.  (KHL comment:  this is an excellent example of the difficulty in separating Allen's from Rufous hummingbirds.  Both species are being seen in here this month; the amount of green on the back suggests the bird could be the female of either species, or could be an Allen's male.  Without a tail spread or a view of the throat, I think it is not possible to identify further.)
