Nutting's flycatcher (Myiarchus nuttingi) is a passerine bird in the tyrant flycatcher family. It breeds in semi-arid desert scrub and tropical deciduous forest from western Mexico to northwest Costa Rica. It is normally a year-round resident, but has been known as an occasional vagrant to southern California and Arizona - (southeastern, central, and western), in the United States. It is named for the zoologist Charles Cleveland Nutting.
Nutting's flycatchers build their nests in a tree cavity or similar natural or man-made hole, and the normal clutch is three to five eggs.
Adult Nutting's flycatchers are 18–19 cm long and weigh 21-23 g. The upper parts are olive brown, with a darker head and short crest. The breast is gray, and the belly is a softly colored yellow. The brown tail feathers are extensively rufous, the wings have rufous outer webs, and there are two dull wing bars. The sexes' markings are similar.
A Nutting's flycatcher may be distinguished from other very similar Myiarchus species by its call, a sharp .
Although this species is primarily an insectivore, catching flies in undergrowth, it will also eat berries.
