The Dusky-capped Flycatcher is often confused with the Dusky Flycatcher since their names are so much alike, but they are different species and yet both are recorded visitors to the Santa Rita Mountains south of Tucson just outside of Green Valley.
This is a small species of flycatcher, with olive to brown on the upperparts and pale gray throat and breast. The stomach is pale yellow. The wings have white and red edges while the tail is plain brown.
Despite its name, the Dusky-capped Flycatcher does not rely on insects for food. It will also eat berries and fruits. When it does choose insects, it snatches them mid-flight.
In the Santa Rita Mountains you would most likely find this species of flycatcher in the oak woodland areas in elevations of around 5000 feet. Some birds will breed here in Arizona, while others will cross down into Mexico.
