Identification

16cm. Upperparts are brown above, dull yellow underparts, with cinnamon rump and tail, and a small, whitish patch marks the throat. It has a spectacular crest, vivid scarlet in males, yellow in females, and ornately decorated with splashes of black and steel-blue tips, which usually lies flat, protruding from the rear of the head. When fully extended it forms a large and impressive, forward-facing fan.

Distribution

From Mexico south through Central America to Panama ("Northern" RF), and in South America in several non-overlapping populations: Northern RF in Colombia and western Venezuela, "Pacific" RF in Ecuador and northernmost Peru, Amazonian RF in estern Venezuela, The Guianas and Amazonian Brazil and "Swainson's" RF in south-east Brazil.

Taxonomy

Six subspecies are recognized[1]:

  • O. c. mexicanus
  • O. c. fraterculus
  • O. c. occidentalis
  • O. c. castelnaui
  • O. c. coronatus
  • O. c. swainsoni

These have in the past been viewed as four species: Northern Royal Flycatcher O. mexicanus including fraterculus, Pacific Royal Flycatcher O. occidentalis, Amazonian Royal Flycatcher O. coronatus including castelnaui, and Swainson's (or Atlantic) Royal Flycatcher O. swainsoni. SACC states that a proposal is needed to clarify the status of these four.

Gill and Donsker (2010) recognise the four-way split and further place this genus in family Tityridae.
