Black Phoebe

Sayornis nigricans

The black phoebe 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 a separate species, the white-winged phoebe. Source
