The Yucatan flycatcher (Myiarchus yucatanensis) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Belize, Guatemala and Mexico. The Yucatan flycatcher is 17.5 to 19 cm (6.9 to 7.5 in) long and weighs 19 to 23 g (0.67 to 0.81 oz). The sexes have the same plumage. Adults of the nominate subspecies have a crown whose feathers have dark brown centers and wide rufescent edges; the feathers form a crest. They have grayish lores and half ring under the eye on an otherwise darker gray face. Their upperparts are olive-green with a rufous tinge on the uppertail coverts. Their wings are mostly brown with wide rufous outer edges on the primaries and pale grayish white outer edges on the other flight feathers. Their greater and median wing coverts have pale gray tips that form indistinct wing bars. Their tail is mostly brown with rufous inner webs on the central feathers and sometimes the others as well. Their throat and breast are gray and their belly and undertail coverts yellow with an olive-green wash on the flanks. Subspecies M. y. lanyoni has little or no rufous on the crown, almost blackish upperparts, and paler yellow underparts than the nominate. M. y. navai has upperparts intermediate between the nominate and lanyuoni and lighter yellow underparts than the nominate. All subspecies have a dark blackish iris, bill, and legs and feet. It is a typical Myiarchus flycatcher and is similar in appearance to the dusky-capped flycatcher (M. tuberculifer), brown-crested flycatcher (M. tyrannulus) and the great crested flycatcher (M. crinitus). However, none of them have a rufescent crown.
