Feeding bread crumbs to a hungry little bird in China Town (San Francisco)
This is a red-winged bicolored Blackbird (Agelaius phoeniceus gubernator).
For more info about this species, go to en.wikipedia.org/wiki/Red-winged_Blackbird.
Remember, birds are in fact flying dinosaurs, the only survivors from this extinct prehistoric animal family that had ruled the world, so they deserve some respect!
