  • Order: Falconiformes
  • Family: Falconidae
  • Monotypic
  • Authors: Courtney Davis and Sean McCann


Distinguishing Characteristics

Red-throated Caracara is a large, long tailed raptor. The plumage is primarily black, with white lower underparts (belly, flanks, and undertail coverts). The face and throat of this caracara are bare; the exposed skin usually is red but may also appear rosy or purple. The cera is bluish gray, and the stout tarsi and toes are bright orange.

Similar Species

Red-throated Caracara has very distinctive appearance and behavior, and is unlikely to be confused with other species. Black Caracara (Daptrius ater) of northern South America is somewhat similar, but is smaller and more slender, is all black, has bright orange or yellow (not red) facial skin, and has a white band across the base of the tail.

Detailed Description

The following description is based on Blake (1977); see also Friedmann (1950) and Wetmore (1965):

Adult: Sexes similar. The plumage is mainly black, glossed with steely blue or greenish. The belly, undertail coverts, and tibial feathers are white. The skin of the face and throat is bare(see Bare Parts), with a few black bristles on the throat. The sides of the head are obscurely streaked with grayish white.

Immature: Plumage similar to adult, but lacking the grayish streaks on the auriculars.


No information is currently known about this species' molting strategy.
