The black phoebe is a beautiful passerine bird belonging to the tyrant-flycatcher family. It breeds from southwest Oregon and California south through Central and South America, where it can be found year-round.

The adult has mainly dark grey upperparts with a white belly; juveniles may show brownish tones instead of grey ones on their back.
Its main diet consists of insects which it catches by hovering over water or flying out after them from perches near rivers or streams – hence why they’re often seen around these places.
