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 was originally described with its current binomial Myiarchus yucatanensis.
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... Wikipedia →

Rare
Under 5% of wildlife watchers report a Yucatán Flycatcher sighting in Celestún Biosphere Reserve on a given day, based on 29 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 191st most-seen of the 297 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
June
In that month about 10% of wildlife watchers report a Yucatán Flycatcher in Celestún Biosphere Reserve on a given day, against under 5% in July to May, the lowest months. That is one of Celestún Biosphere Reserve's wettest months, with about 160 mm of rain against 10 mm in February.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Yucatán Flycatcher sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 6
Of the 6 parks where we can rate Yucatán Flycatcher sightings, Celestún Biosphere Reserve ranks 5th at under 5%. The best odds are in Calakmul Biosphere Reserve (Mexico, about 10%), Tikal National Park (Guatemala, about 10%) and Sian Ka'an Biosphere Reserve (Mexico, under 5%).
Same genus: Myiarchus
The closest relatives of the Yucatán Flycatcher that you can see in Celestún Biosphere Reserve (genus Myiarchus, Myiarchus Flycatchers) are Dusky-capped Flycatcher (about 30%) and Brown-crested Flycatcher (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Yucatán Flycatcher is recorded against all the birds logged in Celestún Biosphere Reserve (29 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
