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 →
