The forest empidonax is a small bird from the tyrant flycatcher family. It inhabits North America in damp alder and willow thickets, where it catches insects on the fly.
The forest empidonax differs from the similar willow empidonax by its sharp song cry. It is beneficial for nature because it regulates the population of insects in forest and swampy areas.
