To get rid of these indigestible parts, raptors cast (regurgitate or vomit) a pellet of fur and bones every 1-2 days. Raptors eat whole prey which means that they eat the fur, feathers, bones, and teeth of their animal meal along with the muscle and organs. In addition to hunting live prey, many birds, such as fish eagles, vultures and condors, eat carrion. The most common prey includes: small and medium mammals, birds, fish, reptiles, amphibians and large insects. In general, the larger the hunter the larger the prey, but many medium and large raptors will also choose easier, smaller meals, especially when small prey is more abundant. Some birds hunt animals on the groundand others catch their prey in the air.ĭifferent types of birds of prey eat a wide range of different animals. Silence is beneficial to a raptor since excessive vocalizations could scare off potential prey. Most raptors are nearly silent birds, with only a few calls used in extreme circumstances, such as an alarm call or the dramatic begging calls of young hatchlings. According to a National Geographic TV program, the highest measured speed of a peregrine falcon is 389 km/h (242 mph). The peregrine falcon is the fastest animal on Earth. Easy gliding and soaring can help a raptor find its prey, while powerful dives and swift pursuit is essential to capture each meal. While most birds are adept fliers, raptors have different flight styles that help them hunt. Only in rare circumstances will these birds be seen in large flocks, such as during peak migration periods or at winter feeding grounds. Unlike many birds that gather in flocks, raptors are almost always anti-social to avoid competition for prey. Owls have very large eyes for their size, 2.2 times greater than the average for birds of the same weight, and positioned at the front of the head.Īll birds of prey have hook-tipped beaks and sharp curved claws called talons. TheirĮxtraordinary eyesight can keep three different fields of view in focus at any one time. They can see clearly up to 8 times as far as humans can, allowing them to spot and focus in on a rabbit or other animal at a distance of about 3.2 kilometers (2 miles). The visual ability of birds of prey is legendary, and the keenness of their eyesight is due to a variety of factors. This body shape reduces drag while flying. In general, the bodies of diurnal birds of prey are fusiform in shape (rounded and tapering at both ends). The tallest diurnal bird of prey is the secretary bird with a height of up to 1.3 m (4.3 ft). The largest North American bird of prey is the California condor with a wingspan of up to 2.9 m (9.5 ft). The largest diurnal bird of prey is the Andean condor, which weighs up to 14 kg (31 lbs) and has a wingspan of up to 3.2 m (10.5 ft). It weigh about 120 g (4.2 oz) and has a wingspan of about 0.2 m (0.7 ft). The smallest North American diurnal bird of prey is the American kestrel. One of the smallest diurnal birds of prey is the pygmy falcon of Africa, which reaches a weight of about 60 g (2.1 oz) and has a wingspan of about 0.3 m (1 ft). The sizes of these birds can vary greatly, but they are generally larger and bulkier than most other birds, which allows them to hunt a greater variety of prey. The nocturnal birds of prey are the owls. From frozen tundras and scorching deserts to dense forests and bustling cities, raptors are key apex predators in every environment.ĭiurnal birds of prey include hawks, eagles, vultures, and falcons.
