Crowned Solitary Eagle

Harpyhaliaetus coronatus

Description

Crowned Solitary Eagles are all gray, except for a black tail that has a single white band and a white tip. The crest is bushy and prominent. The wings are long and broad, and the tail is short. The legs and cere are yellow. Juveniles are brown from above with a buff head and underparts, and brown streaks on breast. The lower belly and legs are heavily barred, and the tail has a clear white subterminal band. Their call is a long, high-pitched whistle, which can be heard from a distance of 2 kilometers. They have a length: 75-85 cm and a weight: 2.9 kg. Crowned Solitary Eagles habit is a semi-open dry country, such as savanna, grassland, sparse woodland, and bushy steppes. They have also been found in hilly areas, gallery forest, and cattle ranches, 0-1,200 meters above sea level. They are semi-crepuscular—crepuscular animals are active during dawn and dusk.

Threats of Endangerment

Harpyhaliaetus coronatus has a very large range in Brazil, Bolivia, Uruguay, Paraguay, and Argentina. Their trends are difficult to detect because they have a low density populations but, given the severity of its threats, it seems likely that a significant loss of numbers is occurring. In Paraguay it appears to be most numerous in the Cerrado of Concepción department; it also continues to be recorded in humid Chaco habitat. They threats include habitat destruction and being hunted are the most pertinent threats. For example in Brazil, campo cerrado habitats are being rapidly destroyed by mechanised agriculture, intensive cattle-ranching, afforestation, invasive grasses, excessive use of pesticides and annual burning. The increasing colonisation is destroying wooded areas and grassland as well.
