The brown-crested flycatcher (Myiarchus tyrannulus) is a passerine bird in the tyrant flycatcher family Tyrannidae. It is found from the southwestern United States south through Mexico and Central America to Costa Rica; on Aruba, Bonaire, Curaçao, Trinidad, and Tobago; and in every mainland South American country except Chile and possibly Ecuador.
The brown-crested flycatcher has a complicated taxonomic history. Its formal description is credited to Statius Müller in his 1776 supplement to earlier work by Carl Linnaeus and Martinus Houttuyn. He coined the binomial Muscicapa tyrannulus, placing it in the Old World flycatcher family.
As of 2025 the brown-crested flycatcher has these seven subspecies: Subspecies M. t. magister was originally named M. mexicanus magister. Wikipedia →

Possible
About 20% of wildlife watchers report a Brown-crested Flycatcher sighting in Calakmul Biosphere Reserve on a given day, based on 141 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 69th most-seen of the 271 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
March
In that month about 40% of wildlife watchers report a Brown-crested Flycatcher in Calakmul Biosphere Reserve on a given day, against about 10% in January, May, August–September and November, the lowest months. That is one of Calakmul Biosphere Reserve's driest months, with about 20 mm of rain against 130 mm in June.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Brown-crested 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.

GBIF citizen-science records
It is estimated from how often the Brown-crested Flycatcher is recorded against all the birds logged in Calakmul Biosphere Reserve (141 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.
