1. Wedge-tailed eagle. Wedge-tailed eagles are Australia's largest birds of prey, with a massive wingspan of between 1.8 and 2.3 metres. The females are larger than the males and both sexes start off as a light reddish brown, darkening with age to almost black.
Fast Facts. The Wedge-tailed Eagle is Australia's largest living bird of prey and one of the largest eagles in the world.
1. Andean Condor. The Andean Condor, an endangered species, is considered the largest bird of prey with an enormous wingspan measuring 3 meters (9.8 feet) and weighing up to 15 kgs (33.1 lbs.). They primarily live in mountainous regions where there is an abundant amount of wind to help their massive body in flight.
Between 80 and 90% of a wedge-tailed eagle's diet is made up of ground-dwelling animals, including mammals and reptiles. Rabbits, wallabies and small kangaroos form the main part of their diet, although they will also eat snakes, lizards, large birds, possums, foxes and feral cats.
Kangaroos have few natural predators: Dingoes , humans, Wedge-tailed Eagles and, before their extermination, Tasmanian Tigers . Introduced carnivores, such as wild dogs and foxes prey on the young, and introduced herbivores compete with kangaroos for food.
Golden Eagles are one of the largest birds in North America. The wings are broad like a Red-tailed Hawk's, but longer. At distance, the head is relatively small and the tail is long, projecting farther behind than the head sticks out in front.

The western tragopan (or jujurana, which means “king of birds”) is one of the most vulnerable pheasants in the world; just 3,300 survive in the wild today. This species can be found only in the western Himalaya and is most protected in the state of Himachal Pradesh, India.
“Australia's rarest and most important bird, it is a living fossil, the sole survivor of its genus and family. “With only 1000 plains-wanderers alive today, any extra pressure may drive the species to extinction, especially from a population as large as the wedge-tailed eagles.”
Provides the first complete overview of the biology of the Australian bustard, Australia's heaviest flying bird.
Red goshawks – unusual, strikingly colorful birds of prey endemic to Australia – have been rapidly vanishing from the continent for decades.
The cassowary is a large, flightless bird most closely related to the emu. Although the emu is taller, the cassowary is the heaviest bird in Australia and the second heaviest in the world after its cousin, the ostrich.

The Harpy Eagle (Harpia harpyja) is considered to be the most powerful eagle in the world. Its thick tarsi (legs), strong toes, and sharp talons make this species a formidable predator.
Other than the harpy eagle, the black wheatear is arguably the strongest bird worldwide. Male birds of this species may carry up to 3 kg or 6.6 pounds of stone at all times to prove their strength to their mates.
The eagle is called the "King of Birds", but this title has also been given to the Philippine Eagle.
Generally a male can lift about 1.5 pounds and a female up to 2.5 to 3 pounds — the latter if there is a good headwind. However, this is not even lifting this weight for more than a few 100 yards and not necessarily up to a nest. On the other hand, many a small cat, or parts of a road killed cat, can be lifted.
The Andean condor is the largest living bird of prey.
The black eagle (Ictinaetus malaiensis) is a bird of prey. Like all eagles, it is in the family Accipitridae, and is the only member of the genus Ictinaetus. They soar over forests in the hilly regions of tropical and subtropical South and Southeast Asia, as well as southeastern China.
Considered the largest eagle in the world in terms of length and wing surface, the giant Philippine eagle averages one meter in height (3 ft) from the tip of its crown feathers to its tail. Only the harpy and Steller's sea eagles outweighs the Philippine eagle in terms of mass.
