Hybrid Hummingbird? (1 Viewer)

Hello All,
This hummingbird has been around my house for close to 3 weeks now, an dI've only gotten this one photo, but I have had many looks. This is in San Anselmo, California. Our house get's many migrant hummingbirds, and we have had rare ones show up in the past. It's real late in the season for most hummingbirds right now, but I want to put this bird up for question. I belie it could possibly be a hybrid hummingbird. It looks a little off for the normal Anna's, as well as being a good deal smaller. This bird was dwarfed by one of the local female Anna's. It seems to have longer wings, but that could just be of the angles I've been getting, but the big thing making me think this bird is different is it's voice. It has a totally different call than your Anna's, but not one I really recognize. It's kind of similar to a Black-chinned, but not really. I've been trying to get audio, but it shows up so infrequently. I can also find it easily by its behavior. It acts like a Black-chinned, where it is always bobbing its tail when it is hovering. I'm suggesting Anna's x Black-chinned, but who knows, this could just be a weird Anna's.

I've seen that one of a female. Those photos of the males are helpful, as I can see that this hybrid combination can have more of an Anna's like bill, which is more like my bird. I have contacted some experts who should get back to me soon. My only concern is the shape of the primaries.

I doubt that the hybrid BCHu-X-Anna would be significantly smaller than Annas given that one is labeled as 3.75 and the other 4 inches long. Is there a general rule in hummers that hybrids are smaller than parent species? if not, then I would look elsewhere.

True, but size does vary. It was about 3/4 of an inch smaller than the other, which is a big difference in hummingbirds. I should focus more on Anna's x Costa's, which I'm guessing would be smaller.
