Daptrius is a genus of birds of prey in the family Falconidae comprising most of the caracaras. All members are endemic to South America, except for the yellow-headed caracara, which is also found in Costa Rica and Panama. The genus includes species previously placed in the genera Milvago and Phalcoboenus.

Taxonomy

The genus Daptrius was introduced in 1816 by the French ornithologist Louis Vieillot to accommodate a single species, Datrius ater Vieillot, the black caracara. This is the type species.[1][2] The genus name is from Ancient Greek δαπτης/daptēs meaning "bloodsucker" or "eater", from δαπτω/daptō meaning "to devour".[3]

This genus now includes species that were formerly placed in the genera Milvago and Phalcoboenus. Molecular genetic studies found that Milvago was polyphyletic with the chimango caracara (Milvago chimango) sister to the genus Phalcoboenus and the yellow-headed caracara (Milvago chimachima) sister to Daptrius.[4][5] As the genetic divergence was relatively shallow, the polyphyly was resolved by expanding the genus Daptrius to include the two other genera.[6]

The genus contains seven species:[6]

Image Common name Scientific name Distribution
Yellow-headed caracara Daptrius chimachima
(formerly in Milvago)		 Costa Rica to north Argentina
Black caracara Daptrius ater Amazonia
Chimango caracara Daptrius chimango
(formerly in Milvago)		 southern South America
Carunculated caracara Daptrius carunculatus
(formerly in Phalcoboenus)		 Ecuador and southwest Colombia
Mountain caracara Daptrius megalopterus
(formerly in Phalcoboenus)		 Peru to central Chile
White-throated caracara Daptrius albogularis
(formerly in Phalcoboenus)		 south Chile and south Argentina
Striated caracara Daptrius australis
(formerly in Phalcoboenus)		 Tierra del Fuego, Isla de los Estados (Staten Island), Navarino Island, and Falkland Islands

Fossil species

D. c. readei, a larger and stouter paleosubspecies of the yellow-headed caracara from the Late Pleistocene of Florida and possibly elsewhere, is also known.
