Empidonax wrightii (Grey Flycatcher; Gray Flycatcher)

Language: Spanish

Wikipedia Abstract

The American gray flycatcher, or just gray flycatcher (Empidonax wrightii) as it is known in North America, is a small, insectivorous passerine in the tyrant flycatcher family. It is common in the arid regions of western North America, especially the Great Basin. From sagebrush steppes to pinyon-juniper woodlands and ponderosa pine forests, this flycatcher forages for insects from shrubs or low tree branches.
