The mountain caracara (Daptrius megalopterus), (Spanish: corequenque) is a species of bird of prey in the family Falconidae. It is found in puna and páramo in the Andes, ranging from northern Ecuador, through Peru and Bolivia, to northern Argentina and Chile. It is generally uncommon to fairly common. It resembles the closely related carunculated caracara and white-throated caracara, but unlike those species, its chest is uniform black. Juveniles are far less distinctive than the red-faced pied adults, being overall brown with dull pinkish-grey facial skin.
The mountain caracara was formally described and illustrated in 1834 by the Prussian naturalist Franz Meyen under the binomial name Aquila megaloptera based on specimens collect in the Cordillera of Chile. The specific epithet combines the Ancient Greek μεγαλως/megalōs meaning "exceedingly" with -πτερος/-pteros meaning "-winged". The species is monotypic: no subspecies are recognised. The mountain caracara was formerly placed in the genus Phalcoboenus. Molecular genetic studies found that the genus Milvago was polyphyletic with the chimango caracara sister to the genus Phalcoboenus and the yellow-headed caracara sister...
