Tropical Royal Flycatcher

The tropical royal flycatcher (Onychorhynchus coronatus) is a passerine bird that most taxonomic systems place in family Onychorhynchidae. It is found in Mexico, south through most of Central America, and in every mainland South American country except Argentina, Chile, Paraguay, and Uruguay. == Taxonomy == The tropical royal flycatcher was formally described in 1776 by the German zoologist Philipp Statius Müller under the binomial name Muscicapa coronata. Müller based his account on a hand-colored illustration of the "Tyran hupé de Cayenne" that had been engraved by François-Nicolas Martinet. The specific epithet is from Latin coronatus meaning "crowned". The tropical royal flycatcher is now placed together with Atlantic royal flycatcher in the genus Onychorhynchus that was introduced in 1810 by the German naturalist Gotthelf Fischer von Waldheim. After a complicated history (which see here), the International Ornithological Committee (IOC) and the Clements taxonomy placed the tropical royal flycatcher and the Atlantic royal flycatcher (O. swainsoni) in family Onychorhynchidae. However, the tropical royal flycatcher's taxonomy remains unsettled. The North and South American Classification Committees of the American Ornithological Society (AOS) combine the tropical and Atlantic royal flycatchers as the widespread royal flycatcher (O. coronatus sensu lato).
