Examples of animals that eat protein include alligators, badgers, anacondas, owls, and eagles. Since squirrels feed primarily on the lower levels of the food chain, they have an extensive list of animals that eat them, including hawks, eagles, bull snakes, weasels, cats, crocodiles, small and large fish, coyotes, dogs, etc. Badgers readily eat squirrels of any type, including chipmunks, marmots, and prairie dogs. Squirrels are not alligators' favorite prey, but alligators will eat them if available.

This means that eagles feed on the meat of other animals, including fish, rabbits, snakes, and squirrels. Many eagles feed primarily on fish, although they also eat many different creatures and species. In addition to catching live prey, eagles rely heavily on carrion from fish, birds and mammals, especially during winter. Eagles eat a wide variety of prey, including reptiles, birds, mammals, and fish.
As the name suggests, ospreys prefer to eat fish, but they are very adaptable to food, eating a variety of prey and carrion. Vultures are opportunistic predators, which means that in addition to hunting live prey, vultures steal from other animals (mainly other eagles or smaller fish-eating birds) or feed on carrion. Bald eagles' diet consists mainly of fish, but they also eat small mammals such as squirrels or rabbits and other small birds. Vultures are opportunistic foragers, which means they won't prey on small mammals like marmots, squirrels, and rabbits if given the chance.
In addition to fish (caught or stolen from other birds), bald eagles eat sick and injured waterfowl, muskrats, squirrels, rabbits, marmots, and often carrion and animals killed on the road. However, bald eagles eat live animals, small animals, birds, beavers, blue herons, ducks, geese, bats, carrion, and coyotes. Eagles will not refuse to eat other predators such as hawks and owls. Bald eagles feed on dead animals, ducks, squirrels, foxes, snakes, cats, crocodiles, ants, dead animals, cats, dogs and other birds.
Although the eagle eats road prey, they consume most of it in the winter, when the dead animals freeze and are unlikely to be covered in larvae, so they do not need the featherless vulture heads.
Most species of eagles will eat dead animals during times of food shortage if they can't find anything better. Many species of eagles are carnivorous predators, some have a more specialized diet than other eagles. Yes, eagles are birds of prey (meat eaters), sometimes they eat cats, but their favorite foods are fish, birds and wild birds.
Horned eagles also eat seabirds, squirrels, muskrats, raccoons and other small mammals, reptiles, snakes, crustaceans, and even litter, as well as deer or cow carcasses (if available). In addition to fish and waterfowl, eagles prey on a variety of small mammals and reptiles such as mice, rabbits, squirrels, marmots, snakes, and other similarly sized creatures. Golden eagles also eat arctic ground squirrels, marmots, black grouse and partridges.
In particular, golden eagles feed on a variety of rodents, reptiles, birds, and even larger mammals such as deer and foxes. Golden eagles (also known as Adler birds) may also prey on larger animals such as foxes, young deer, and carrion. Golden eagles prey on many small to medium animals, especially rabbits and squirrels, but are also known for preying on larger animals such as foxes and goats. When food is scarce, the eagle's diet also includes large birds and animals such as deer, livestock, sheep and goats; golden eagles then attack eaglets, hawks and owls.
Golden eagles sometimes prey on deer and pronghorn (mostly deer), waterfowl, black grouse, weasels, skunks and other animals. There are many differences in the food biology of the two species as they feed primarily on fish, sometimes supplemented by waterfowl or other semi-aquatic prey, and obtain more food by searching for dead or injured animals or through kleptoparasitism than do golden eagles. The iconic bald eagle is thought to consume around 400 species, consisting primarily of fish (averaging over 50% of their diet), birds (averaging 25%+ of their diet), and mammals (15%+ of their diet in the media). , the rest is other prey such as lizards.
Given the predatory nature of the bald eagle's diet, bald eagles eat cats and dogs, gray squirrels, lambs, small dogs, sheep, chicks, turtles, turkeys, wild turkeys, and waterfowl. Examples of organisms that eat eagles (at various stages of their life cycle) include raccoons, coyotes, great horned owls, crows, squirrels, foxes, and wolves. Eagles' favorite foods are eel, lamprey, squirrel, hare, bird meal, and so on. The bird feeds mainly on road debris and piles of intestines left by hunters when streams freeze in winter. Although there are regional and seasonal differences in feeding habits, golden eagle prey consists mainly of small mammals such as hares, cottontails, prairie dogs, and ground squirrels.
Eagles obtain food mainly in three ways: by direct capture, by preying on carrion, and by stealing food from other birds and mammals. Mammals also eat smaller birds, the eggs of other birds, and small animals such as rabbits, reptiles, amphibians, and crabs. The goshawk feeds mainly on birds, but also eats rodents, including squirrels.
