Bald eagles are well adapted to their lifestyle. They possess sharp, pointed beaks designed for ripping and tearing prey into bite-sized pieces. Eagles have powerful legs and feet that are equipped with large talons used for killing their prey.

Bald eagles are opportunistic foragers but prefer fish as their primary food and are found in great densities where fish are abundant. Eagles will also eat sea birds and ducks or hunt over grasslands and marshes for small mammals such as rabbits, squirrels, prairie dogs and muskrats. Bald eagles eat carrion willingly and are notorious for robbing osprey of their catches. Eagles wait on a favorite perch for an osprey to return to its nest with a fish in its talons for its own young, and then harass the smaller raptor until it is forced to drop its prey for the eagle to retrieve. When hunting for fishes, Eagles do not usually dive into the water like the osprey but instead searches for fish near the surface.
