What Do Birds of Prey Eat?

What Do Birds of Prey Eat? Birds of prey are those that feed wholly or mainly on meat taken by hunting. They catch other birds, and small animals, for their food.

There are two chief families, the hawks and the falcons. The hawks include eagles, such as the bald eagle (symbol of the United States) and the golden eagle. The falcons are smaller but share the same general characteristics-hooked beaks, keen vision and outstanding powers of flight. Owls, also, feed on flesh.

Besides being fast fliers, many birds of prey are expert at gliding and hovering. Their principal strategy of attack is the ‘stoop’, when from a great height they sight their prey, close their wings and swoop upon the victim. This maneuver calls for a combination of speed and last-second braking unique to this type of bird.

Different types of birds of prey eat a wide range of different animals. In general, the larger the bird the larger the prey, but many medium and large raptors will also choose easier, smaller meals. The most common prey of raptors includes:

Large Insects: Grasshoppers, praying mantises, beetles and other large insects are the preferred prey of small raptors such as American kestrels, merlins and Mississippi kites. Raptors that spend a large amount of time on the ground, such as burrowing owls, also eat a lot of insects.

Fish: Birds of prey that live along coastlines or near large bodies of water often hunt fish, in some cases poaching it from other predators such as bears, raccoons and mountain lions. Fish is the majority of the diet for bald eagles and osprey, and the snowy owl will also occasionally eat fish.

Small Mammals: Small mammals such as mice, voles, shrews and gophers are the most popular prey for medium and large raptors. Red-tailed hawks, northern harriers, Cooper’s hawks, barn owls, merlins and many other species hunt small mammals, either by perching and scanning fields or by soaring to spot prey.

Small Birds: Many small birds including finches, sparrows and songbirds are prey for larger birds. Depending on the raptor species, they may surprise the smaller birds on the ground or catch them in mid-flight, either through diving or after an acrobatic aerial chase.

Large Birds: Larger birds such as pigeons, doves, ducks and grouse often become prey for larger raptors. Fierce predators such as the northern goshawk and the swift diving peregrine falcon feed frequently on larger birds.

Medium Mammals: Medium-sized mammals such as rabbits, raccoons and large squirrels are regular parts of the diet of large birds of prey. Red-tailed hawks, ferruginous hawks, northern goshawks and golden eagles hunt these bigger mammals.

Carrion: Dead animals and rotting carcasses are the primary diet of scavenging raptors such as the turkey vulture and the California condor. Other large raptors, including golden and bald eagles, will also choose an easy meal like carrion if it is available.

Reptiles: Snakes and lizards are popular prey for desert-dwelling raptors such as the crested caracara. The barred owl is also known to feed frequently on reptiles.

Amphibians: Smaller birds of prey and those that prefer habitats near water often feed on amphibians such as frogs and salamanders. Red-shouldered hawks and American kestrels often include amphibians in their diet.

In advanced countries birds of prey have suffered severely from the effects of poisonous agricultural sprays which have polluted their food sources. This has threatened their survival. But the danger has now been recognized, and in many areas their numbers are slowly recovering.
