The harpy eagle (Harpia harpyja), the Philippine eagle (Pithecophaga jefferyi), and the Steller's sea eagle (Haliaeetus pelagicus) are the largest and most powerful living eagles, and the first two also have a similarly reduced relative wing-length as an adaptation to forest-dwelling. It is very common in the Northern hemisphere and the most widely found eagle species. It has a pale beak, white feet and dark brown color around the eyes. The Philippine eagle, also known as the great monkey-eating eagle, has a wingspan of between 184-220 cm and a body mass of 4.5kg-8kg. Several of the largest extant Old World vultures, if not in mean mass or other linear measurements, probably exceed Haast's eagle in average wingspan as well. The biggest and most powerful birds of prey The world’s largest predatory birds. With a wingspan of up to 2 meters, it’s a good navigator across Central and South America. [17][20][21], The talons of the Haast's eagle were similar in length to those of the harpy eagle, with a front-left talon length of 4.9 to 6.15 cm (1.93 to 2.42 in) and a hallux-claw of possibly up to 11 cm (4.3 in). It is the most powerful bird of prey in North America and known for its swiftness and strength. Based on numerous analyses related to these birds’ prey size, their aggressiveness and the proportion of the bird’s body size in relation to the prey size, we have appointed the winner and the whole list in that category. Below are some of the biggest eagles in the world in terms of total length, wingspan and body mass. [26] However, it has also been argued that the "Hakawai" and "Hokioi" legends refer to the Coenocorypha snipe—in particular the extinct South Island species.

Harpy Eagle is largest and most powerful birds of prey in the world,inhabits tropical lowland rainforests. Southern cassowary is probably the most dangerous living bird in the world. [11] Female eagles were significantly larger than males. In the avian kingdom, eagles can be found at the very top of the food chain. [14], They had a relatively short wingspan for their size. Considering the size, Southern Cassowary is the second largest bird in the world – weigh between 75 – 80 kg and upto 5.1 in height. [8], Early human settlers in New Zealand (the ancestors of the Māori arrived around the year 1280) preyed heavily on large flightless birds, including all moa species, eventually hunting them to extinction by around 1400. Australian Wedge-Tailed Eagle, 230 cm (90.55 inches) 5. The Blakiston’s Fish Owl is the largest owl in the world. with a wingspan of 2 meters (6.5 feet). The species was the largest eagle known to have existed, with an estimated weight of 15 kilograms (33 lb) nearly double that of the Harpy eagle at 9 kilograms (20 lb). One study estimated the total population at 3,000 to 4,500 breeding pairs, so the Haast's eagle would have been very vulnerable to changes in the number of moa. The largest eagles in the world – Top 10 The heaviest eagles 1. Harpy eagle (Harpia harpyja) average weight: 5.95 kg (13.1 lb) [18], Some wing and leg remains of Haast's eagles permit direct comparison with living eagles. The Eurasian Eagle Owl is found in the mountains and forests of Europe and Asia weighing up to 4.2 kgs (9.2 lbs.) It feeds on small mammals such as jackrabbits and can sometimes attack large mammals such as lambs, goats and other domestic animals. As the name suggests, it is endemic to the rainforests of the Philippines. [12] Total length is estimated to have been up to 1.4 m (4 ft 7 in) in females, with a standing height of approximately 90 cm (2 ft 11 in) tall or perhaps slightly greater. [citation needed] Due to the absence of other large predators or kleptoparasites, a Haast's eagle could easily have monopolised a single large kill over a number of days.[1]. It is covered with black feathers for the most part except on the wings in the shoulder area and the legs and lower body which are much brighter. Birds occupied or dominated all major niches in the New Zealand animal ecology. This eagle is currently faced with the danger of extinction due to habitat exploitation. This bird of prey is among the largest and most powerful owls in the world. The harpy eagle is a powerful bird of prey and one of the largest in the world. Unlike the other large flying birds on this list, the female Eurasian Black Vultures are larger than the males.

Fish is the major diet while mammals such as fox, sheep roe deer have been recorded as regular prey. [13] The Philippine eagle might be a particularly appropriate living species to compare with the Haast's eagle, because it too evolved in an insular environment from smaller ancestors (apparently basal snake eagles) to island gigantism in the absence of large carnivorous mammals and other competing predators. In some Māori legends, Pouakai kill humans, which scientists believe could have been possible if the name relates to the eagle, given the massive size and strength of the bird. They are very successful birds in terms of hunting down prey and weathering the harshest environmental conditions. White-tailed Eagle, 244 cm (96 inches) 4. 1.
