Pacific-slope Flycatcher - Empidonax difficilis

The Pacific-slope Flycatcher and the Cordilleran Flycatcher are virtually identical, and were once considered one species, the "Western Flycatcher". In appearance, there's very little to tell the species apart, although the Pacific-slope Flycatcher is said to be very slightly smaller with a slightly shorter bill. The easiest way to tell the two species apart is by voice, and by geographic range.

Habitat

Found in moist forests near the Pacific coast, and while it can be found in areas dominated by conifer forest, they are most commonly found in pockets of deciduous forest.

Diet

Feeds on insects and spiders. They will also occasionally eat berries and seeds.

Behavior

Forages by observing from a perch, and then flying out to capture insects in mid-air, or hovering and gleaning insects from foliage and branches.

Nesting

The nest of a Pacific-slope Flycatcher is an open cup built of mosses, strips of bark, grasses, and leaves, lined with finer vegetative material. The female usually lays 3 or 4 eggs, and she alone incubates them. When the eggs hatch, both parents help to feed the young. The young fledge after about 2 weeks.

Song

Song of a Pacific-slope Flycatcher is a high-pitched series of three phrases... ptsip..seewi...tseet.

Migration

Well-named, the Pacific-slope Flycatcher summers in forests near the Pacific coast. In winter, it is found in western and southern Mexico.
