The Egyptian vulture is a rare example of adaptation: it is fond of eggs (mostly ostrich eggs), but has to first break them. They lie in wait on a perch near the water and catch fish that swim up to the surface. Some raptors have evolved to adapt and specialise their diet: sea eagles, for instance, feed on fish, which are more plentiful than rodents. Buzzards and kites: they like some reptiles.Owls: only rodents (field mice, mice, voles, etc.).In theory, a bird of prey can eat any prey smaller than itself however, every species has its own food preferences. While they do have access to water at the aviary, it is to enable them to bathe every day and keep their feathers in perfect condition for flight. Some raptors never drink water in their entire lives. ![]() Moreover, meat is 80% water, so they do not need to drink unless the weather is really very hot. Since they cannot digest bones, feathers, fur or teeth, they spit these out in the form of a small tight ball called a “pellet”. It is almost non-existent, except for three species (out of more than 550): the turkey vulture (Cathartes aura), the Andean condor and the king vulture (Sarcoramphus papa), all of which are new world vultures.īirds of prey find everything they need, and more, in meat. ![]() While sight and hearing are highly developed, that is not true of smell. It allows snowy owls to hear lemmings under the snow. On the other hand, it is essential for nocturnal raptors, so much so that they even have silent plumage to make the most of it. Even though their asymmetrical ears give them excellent hearing, that sense is used very little by daytime raptors. The other crucial sense for locating prey is hearing. In fact, they cannot even grasp a mouse with their feet. If given the opportunity, hunting raptors will readily feed on carrion, but scavengers never hunt. That variety of prey animals could partly explain the variety of raptor species. However, most of them catch mammals (mainly rodents) or birds. Hunting birds of prey feed on all possible sources of meat: kites feed on insects, some eagles eat snakes, sea eagles and osprey feed on fish, while marsh harriers eat frogs. Raptors are divided into two families based on what they eat: hunters and scavengers. If the bird hunts by lying in wait for its prey, it lands on a pole, an electricity line or hovers.įinally, some use hunting flight: these include nocturnal raptors, goshawks and hawks, which have short, rounded broad wings that allow them to fly skilfully through vegetation. Then it stops flapping its wings, keeps going and brakes at the moment of capture. In pursuit, the bird of prey flies fast until it is only a few metres away from its prey. This way of flying is extremely tiring and is used for short periods of time. Those who use flapping flight often have long, pointed wings like hawks. With their wings spread out, they use the lift offered by thermal updrafts by making spiral circles. Those who use gliding are often those with wide wings and long tails such as vultures and eagles, and also buzzards and kites to a lesser extent. others patrol their territory for hours in search of carcasses using gliding flight.they may chase down very fast prey using flapping flight.The oldest known birds of prey are vultures that lived during the Eocene epoch, 60 million years ago.īirds of prey hunt in a wide variety of ways: They feed on small mammals such as rodents. These are solitary birds that hunt at dusk or at night, but some species are also active during the day (like the short-eared owl for example). Their very soft plumage makes their flight silent. Nocturnal raptors also have hooked beaks and talons, but they are best recognized by their broad head and large eyes surrounded by feathers forming two facial discs. They do not have talons, only feet that cannot grip and carry away: they do not need to have such feet, as they do not kill prey. They nest on trees or on rocks and cliffs. They are mostly excellent hunters with piercing eyesight. Raptors include two orders: the Falconiformes or diurnal raptors and the Strigiformes or nocturnal raptors.ĭiurnal raptors are characterized by their short-hooked beak and powerful, clawed feet. ![]() In hawks, the male is known as the tiercel and is smaller than the female (about a third less in weight).
