A bald eagle is a carnivore, primarily consuming meat. This allows them to thrive in various ecosystems across North America. This article explores the classification of carnivores and the specific dietary habits and hunting strategies that define the bald eagle as a predatory bird.
Defining Carnivores
Carnivores are animals whose diets are composed mainly or exclusively of animal tissue, or flesh. The term “carnivore” originates from Latin, meaning “meat eater.” These animals typically possess adaptations such as sharp teeth or talons for capturing and consuming prey. Carnivores can be further categorized based on the proportion of meat in their diet. Obligate carnivores, also known as hypercarnivores, rely on meat for at least 70% of their diet, while mesocarnivores depend on meat for at least 50%. Bald eagles fit the description of a carnivore, primarily consuming animal protein to meet their nutritional and energy needs.
What Bald Eagles Eat
Fish constitute the largest portion of a bald eagle’s diet, often making up between 70% to 90% of their food intake. They prey on a variety of fish species, including salmon, catfish, herring, and shad. Bald eagles are also opportunistic eaters, consuming other available prey if fish are scarce or easier to acquire.
Beyond fish, their diet includes various waterfowl such as ducks, geese, and coots. Small mammals like rabbits, squirrels, prairie dogs, raccoons, and muskrats are also common prey. They may also consume reptiles like turtles and snakes, as well as amphibians and crabs. Bald eagles also readily eat carrion, the remains of dead animals, especially during winter months when live prey might be harder to find.
How Bald Eagles Find Food
Bald eagles employ diverse strategies to acquire their food. One common method involves watching from a high perch, then swooping down to snatch prey, particularly fish, from the water’s surface with their powerful talons. They can also hunt by flying low over land or water, surprising their prey. When fish are abundant, such as during spawning runs, bald eagles may even wade in shallow waters to pursue them.
Their opportunistic nature extends to scavenging, where they feed on dead animals like roadkill or other carcasses. Bald eagles also engage in kleptoparasitism, the act of stealing food from other animals. They are known to harass other raptors, such as ospreys, until the victim drops its catch, which the eagle then retrieves.
