Olive-sided Flycatcher

Contopus borealis - Fairly common in northern coniferous woods, locally in aspens, birch, maple, and eucalyptus. Resembles Eastern Phoebe, but the head and bill are much larger and the tail is shorter. The white throat and breast streak contrast with the dark olive sides. White tufts under wings often protrude. Habitually returns to same perch at the top of a dead snag. Song is a loud melodious whistle, whip-three-beers, 6-10 minutes; call, pip-pip-pip.
