Black Phoebe
The Black Phoebe is a medium-sized flycatcher with sooty-black plumage except for a white belly and vent, and a characteristic erect, upright posture. It is found throughout western North America south through Central and South America to Argentina, invariably near permanent water such as streams, ponds, and coastal areas. It feeds on flying insects caught in low, acrobatic sallies over water or ground.
