The solitary eagle or montane solitary eagle (Buteogallus solitarius) is a large Neotropical eagle. It is also known as the black solitary eagle.
Range and habitat
The solitary eagle is native to Mexico and Central and South America. It is found in mountainous or hilly forests, at elevations between 600 m and 2,200 m. The frequent reports from lowlands are usually misidentifications of another species, usually the common black hawk or great black hawk; no reports from lowlands have been confirmed. It is rare in all areas of its range and poorly known. Very little is known about its diet, other than that it appears to have often been predating large snakes and one adult pair was seen hunting deer fawns. The remains of a chachalaca were noted in one nest.
The adult solitary eagle is uniformly dark gray, often appearing black, with white markings on the tail. It is 63–76 cm (25 to 30 inches) long, weighs 2.75 kg (6 lbs), and has a 152–188 cm (60 to 74 inch) wingspan. It appears very similar to the common black hawk and great black hawk, but is much larger and has significantly broader wings, extending nearly to the tip of the tail. The exceptionally broad wings are one of the prime distinguishing characteristics of this species. Its body also has quite a thickset appearance.
The juvenile is mottled brown and tan, with markings around the eyes. It otherwise resembles the adult.
