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 Saguaro National Park on a given day, based on 1,431 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 35th most-seen of the 220 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
July
In that month about 70% of wildlife watchers report a Brown-crested Flycatcher in Saguaro National Park on a given day, against under 5% in September to March, the lowest months. That is one of Saguaro National Park's wettest months, with about 55 mm of rain against almost none in May.
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.
12th of 47
Of the 47 parks where we can rate Brown-crested Flycatcher sightings, Saguaro National Park ranks 12th at about 20%. The best odds are in Santa Rosa National Park (Costa Rica, about 50%), Las Baulas Marine National Park (Costa Rica, about 30%) and Rincón de la Vieja National Park (Costa Rica, about 30%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Brown-crested Flycatcher is recorded against all the birds logged in Saguaro National Park (1,431 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.
