The Gray Flycatcher has a very unassuming and boring name, but this small species caused a lot of confusion until early in the 20th century. A winter visitor to Arizona, including the woodland areas of the Santa Rita Mountains south of Tucson, the Gray Flycatcher looks so much like other species, it took ornithologists a while to discover this one was unique.
Although the name implies the Gray Flycatcher is gray, it really is more olive in color, and has a white eye ring. The upper beak is darker gray, while underneath it is a pale pink. The have dark wings with white bars, and a long dark tail with white on the edges. The Gray Flycatcher looks so much like the Dusky Flycatcher, it will take a lot of practice and a good eye to tell them apart.
