Dusky-capped Flycatcher

Myiarchus tuberculifer

The mournful whistle of the Dusky-capped Flycatcher is a common sound in woodlands almost throughout the American tropics. This bird reaches its northern limits in Arizona and New Mexico, where it is common in summer in canyons and pine-oak forest. There are places in the lower canyons of Arizona where it can be found side by side with two close relatives in the crested flycatcher group, the Ash-throated and Brown-crested flycatchers.

Conservation status	Numbers in Arizona vary from year to year, but no obvious long-term trend.
Family	Tyrant Flycatchers
Habitat	Oak slopes, pine-oak canyons, junipers. In United States, usually found around tall oaks or pine-oak woods in the mountains. Also found along streams at middle elevations among tall cottonwoods and sycamores. In the tropics, inhabits many types of forest.

Nesting

Nesting behavior is not well known. Male defends nesting territory in spring with conspicuous calls and song. Nest site is in hole in tree (often oak or sycamore), either a natural cavity or an old woodpecker hole. Height varies, 10-60' above the ground, but usually fairly high. Nest built inside cavity is a bulky mass of weeds, grass, twigs, strips of bark, plant fibers, leaves, and feathers, with a lining of softer material such as animal hair or plant down.
