Oops, I had the recordings of the hummingbirds mixed up. I'll have to go over them some more, but it is not the broadtail that I remember hearing in my neighbor's mulberry tree.

I listened to the raven recordings, then the bird that likes my palm tree, and to some of the related bird recordings. I'm almost sure that is a raven up there, and I am now absolutely sure it is not a crow.

There is at least one other raven in the neighborhood, if that is what that bird really is. I understand, from my reading, they do live in the area.
