The bird was perched on a tree in my backyard. I could not get a photo, but will try again the next time I see it.

The Black Phoebe (Sayornis nigricans) is a passerine bird in the tyrant-flycatcher family. It breeds from southwest Oregon and California south through Central and South America. It occurs year-round throughout most of its range and migrates less than the other birds in its genus, though its northern populations are partially migratory. Six subspecies are commonly recognized, although two are occasionally combined as separate species, the White-winged Phoebe.
