Pacific-slope flycatcher facts talk about this bird, its status of conservation, and description.

The Pacific-slope flycatcher (Empidonax difficilis), one of the two species of the western flycatcher along with the other species of Cordilleran flycatcher, lives in the countries of North America. The fact that it is difficult to distinguish the two species is due to their physical similarities.

Pacific-slope flycatcher identification relies on its vocalizations that are slightly different from the other western species, the Cordilleran flycatcher of the order Passeriformes, family Tyrannidae.

Empidonax flycatchers live in the wild habitats of mixed woods including deciduous, coniferous woodlands in southern California, Mexico, Arizona, the Channel Islands, and along the Pacific coast in North America. The harsh cold winter months are spent by these birds in coastal lowlands and the southern part of Mexico.

The species is mostly insectivorous and are found to wait patiently on a tree perch to catch their prey. They mainly eat spiders, moths, bees, bugs, beetles, and wasps.

This bird species has yellowish olive underparts and brownish strokes on the upper part of the wings. They have a broader bill and a large head along with a long tail and grey legs. Their broader bill helps them to catch their prey.
