The Harpy Eagle is one of the largest and most powerful raptors found in the rainforests of Guyana.  It usually inhabits tropical lowland rainforests in the upper canopy of trees. They can be distinguished from others by their slate black feathers and a white underbelly. The double crest is another majestic feature of the Harpy Eagle. Since the plumage of the males and females are the same, it is difficult to identify the bird by gender. This bird can weigh up to 9 kilograms. With a wingspan of 6 feet, the harpy eagle is able to easily manoeuvre in forested habitats to get to prey like sloths, monkeys, and other mammals. As South America’s largest eagle, it is also known as the ‘flying wolf’. The Harpy Eagle can be found in the central forests of Guyana. Even though they are getting harder to spot, naturalists keep themselves abreast of nesting sites to show birders. Known nests exist at Surama, Rewa, Warapoka and the Kanuku Mountains.
