Language: French; Spanish

Wikipedia Abstract

The alder flycatcher (Empidonax alnorum) is a small insect-eating bird of the tyrant flycatcher family. The genus name Empidonax is from Ancient Greek empis, "gnat", and anax, "master". The specific alnorum is Latin and means "of the alders". Their breeding habitat is deciduous thickets, often alders or willows, near water across Canada, Alaska and the northeastern United States. They make a cup nest low in a vertical fork in a shrub. These birds migrate to South America, usually selecting winter habitat near water. This bird's song is a wheezed ree-BEE-a. The call is a quick preet.
