Tyrant-flycatchers (Tyrannidae)

Royal Flycatcher (Onychorynchus coronatus) - HBW 9, p. 345

French: Porte-éventail roi German: Kronentyrann Spanish: Mosquero Real
Other common names: Crowned Flycatcher; Northern Royal Flycatcher (mexicanus, fraterculus); Amazonian Royal Flycatcher (coronatus, castelnaui); Pacific Royal Flycatcher (occidentalis); Atlantic Royal Flycatcher (swainsoni)

Taxonomy: Muscicapa coronata Statius Muller, 1776, Cayenne.
Thought to be closest to Platyrinchus on basis of cranial and syringeal characters. Despite apparent similarity in voice across range, is sometimes split into four separate species on grounds of plumage variation and allopatric distributions, one in N (mexicanus, fraterculus), one in Amazonia (nominate, castelnaui), one in W (occidentalis) and one in E (swainsoni); further research required in order to determine validity or otherwise of such treatment. Within these groups racial variation doubtful; in particular, birds intermediate between mexicanu.. View all taxonomy...

Taxonomy: Muscicapa coronata Statius Muller, 1776, Cayenne.
Thought to be closest to Platyrinchus on basis of cranial and syringeal characters.

Within these groups racial variation doubtful; in particular, birds intermediate between mexicanus and fraterculus occur in Costa Rica and Panama. Six subspecies recognized.

Subspecies and Distribution:

  • mexicanus ( P. L. Sclater, 1857) - S & E Mexico S to Panama.
  • fraterculus Bangs, 1902 - N Colombia and NW Venezuela.
