The Philippine Eagle hunts mostly Flying Lemurs and Palm Civets and, to a lesser extent, small monkeys, squirrels, bats, and rats. Like the Harpy Eagle, the magnificent Philippine Eagle also lives in dense tropical forests and hunt arboreal mammals, but its average prey size is smaller. The Philippine Eagle comes in third place. Overall, the Steller’s Sea Eagle does not use its size as a tool to subdue its prey. On rare occasions, Steller’s Sea Eagles have been observed killing small birds that are injured or unable to fly. The average length and weight of the Pacific Salmon are 40.6 cm (16″) and 1.8 kg (lb), respectively. The similarly heavy female Steller’s Sea Eagle feed mainly on dead or live fish, especially Pacific salmon, and to a lesser extent, carcasses found near the coastline.

The average prey size of a Harpy Eagle prey is 5.3 kg (11.6 lb). Females Harpy Eagles have been reported to attack monkeys in the canopy, followed by a struggle as both the eagle and prey fall and fight on the ground. The female Harpy Eagle regularly hunts for sloths, monkeys, and other medium-sized arboreal mammals. When it comes to strength and power, the female Harpy Eagle is in a league of her own. In a more distant third place comes the Philippine Eagle. The Harpy Eagle is the world’s heaviest eagle, followed closely by the Steller’s Sea Eagle. It is believed that the female Harpy Eagle chooses small males to make sure she can protect herself, the egg, or chick from the attack of smaller but aggressive males. Male Harpy Eagles have a reputation of having sudden bursts of aggression towards females. The larger female can protect the eggs and chicks, even from large predators such as monkeys.īecause there is a greater amount of smaller prey in nature, the smaller male may be better equipped to consistently hunt and feed the female and chick in the nest. During this period, the male provides food for the female and the growing chick in the nest. The female Harpy Eagle does most of the incubation and stays on the nest during the first months after the egg hatches, protecting the young chick.

Different roles of males and females during breeding.

Body size is then regarded as a measure of power and strength. The smaller male can hunt smaller and faster-moving prey while the female is better equipped to prey upon larger but less agile prey. Some ornithologists propose that the difference in size among raptors allows them to hunt prey of different sizes, therefore not competing for the same prey. Some ideas that may help explain such difference include: The reason for such size disparity between sexes has not been determined with certainty. But in some birds of prey, the female can be half as heavy as the male.

In most birds, the male is larger than the female.
