@plantladylin They're beautiful! I'm just learning but apparently Allen's get confused with Rufouses which look similar. Also looks quite possible to spot Ruby-throated hummers in southern California, particularly as you were in San Diego, so close to Mexico.

And Lin, you know that gorgeous Bird of Paradise is the official flower of the City of Los Angeles?
Just the one hummingbird, pictured here last January!
