The Brown-crested Flycatcher, Myiarchus tyrannulus, is a passerine bird in the tyrant flycatcher family. It breeds in open woodland from southern California, southern Nevada, central Arizona, and southern Texas southward to Argentina and Bolivia, and on Trinidad and Tobago. It is resident in most of its range, but individuals breeding in the United States retreat to Mexico or southern Florida in winter.
Adult Brown-crested Flycatchers are 20.3cm long and weigh 30g, and have heavy bills. The upperparts are olive brown, with a darker head and short crest. The breast is grey and the belly is lemon yellow. The brown tail feathers has rufous inner webs, the remiges have rufous outer webs, and there are two dull wing bars. The sexes are similar.
The Brown-crested Flycatcher is best separated from other confusingly similar Myiarchus species by its call, a rough loud come HERE, come HERE or whit-will-do, whit-will-do.
This species is a rather skulking insectivore which catches its prey by flycatching amongst the undergrowth; in sometimes also eats fruit. The nest is built in a tree cavity or similar natural or man-made hole, and the normal clutch is two or three purple-marked cream eggs.
