A Bald Eagle's Diet and Feeding Habits

eagle eating a fish   The bald eagle (Haliaeetus leucocephalus) is a member of the sea and fish eagle group. Its closest relatives, similar in appearance and habit, are found in Africa and Asia. Bald eagles live along the coast as well as by major lakes and rivers. Even though they are fish eaters, they will take ducks and birds or whatever prey is available and easiest to obtain. They fish in both fresh and salt water.

   Because of their size, bald eagles sit at the top of their food chain. This makes them more vulnerable to toxic chemicals in the environment, since each link in the food chain tends to concentrate chemicals from the lower link.

   A bald eagle's lifting power is about 4 pounds. They do not generally feed on chickens or other domestic livestock, but they will make use of available food sources. Bald eagles will take advantage of carrion (dead and decaying flesh), giving it a scavenger image, which causes some people to dislike eagles. Other people do not care for powerful and aggressive birds; while some object merely on the grounds that it is a bird of prey which kills other animals for food.
   Once an eagle spots a fish swimming or floating near the water surface, it approaches its prey in a shallow glide and then snatches the fish out of the water with a quick swipe of its talons. Eagles can open and close their talons at will; although, a hungry eagle can be dragged into the water when refusing to release a heavy fish. Unfortunately, the eagle might drown during the encounter with the fish; eagles are strong swimmers, but if the water is very cold, the bird might be overcome by hypothermia. If an eagle falls into the water during an aerial fight over food with another eagle or accidentally falls into the water, they are able to take flight from the water surface.

   For a scavenger like the bald eagle, a seal or deer carcass would be an unexpected large food supply. Rich in protein, the bodies will feed a group of eagles for days. Though many calories will be obtained, they will be lost in fighting over the food.
   Because of the energy expended during hunting, an eagle has to spend a lot of time resting quietly. It's estimated that only one out of eighteen attempts at attacking its prey is successful.
   Though not as fast as falcons, bald eagles are fast fliers; when diving, where lift is less important than reaching drag, the eagle pulls in its wings to minimize their surface area.
   Bald eagles have been seen hunting in pairs.

   An eagle protects its food by partially opening its wings or tenting. Eagle eating during flight   An eagle can consume one pound of fish in about four minutes; the eagle holds its prey with one talon, holds onto its perch with the other, then tears off each bite with its beak.
   Being opportunists, a bald eagle will steal food from other bald eagles as well as other species. Chasing another raptor is usually enough to persuade it to drop its kill, but occasionally a bald eagle will attack.   Bald eagles do not have to eat every day, but if the bird goes too long without food, it may not be able to hunt effectively enough to survive.
   Eagles have an out pouching of the esophagus, called a crop, where they can store food when the stomach is full. The crop also separates indigestible substances, such as feathers, fur, and scales from the meat. The indigestible substance is mixed with mucus and formed into a mass. After the meal, the eagle eventually regurgitates the mass as a casting.
