Fish in the Bald Eagle Diet

The bald eagle’s affinity for fish is well-known, with fish comprising the majority of their diet. These birds are skilled hunters and prefer to catch live fish instead of scavenging.

Fish species consumed by bald eagles

Common Fish SpeciesDescription
SalmonOne of the primary species of fish consumed by bald eagles. They swim upstream in large numbers during spawning season and make for an easy and abundant food source.
TroutBald eagles are known to target both rainbow and cutthroat trout, which are found in many of the same rivers as salmon.
HerringFound in coastal areas, herring are a small, oily fish that are a common prey item for bald eagles.
CatfishThese bottom-dwelling fish are found in rivers and lakes across North America and are often targeted by bald eagles.
EelWhile not a particularly common prey item for bald eagles, they have been known to consume eels in coastal areas.

Bald eagles are also capable of catching larger fish, such as sturgeon, using their powerful talons to grip onto the fish as they fly away.

Importance of fish in the bald eagle diet

Fish are an important part of the bald eagle’s diet due to their high nutritional value. They are an excellent source of protein, fat, and other essential nutrients that are necessary for the eagle’s survival and overall health.

In addition to their nutritional benefits, fish are also a readily available food source for bald eagles. This is especially true during salmon spawning season, when large numbers of fish are concentrated in rivers and streams, making them easy for eagles to catch.

Waterfowl and Seabirds

Bald eagles are not just fish eaters; they also hunt for waterfowl and seabirds in their natural habitats. These birds are opportunistic predators, meaning that they take advantage of any available food source. They have been known to feed on ducks, geese, and various seabirds, including gulls and puffins.

When hunting for waterfowl, bald eagles use their sharp talons to snatch the birds from the air or water. They are incredibly skilled and can catch and kill birds twice their size. Bald eagles also scavenge for carcasses of waterfowl, often stealing them from other predators or feeding on already dead birds.

Seabirds are another important part of the bald eagle’s diet. These birds are often found in large colonies, making them an easy target for the eagles. They use their powerful wings to soar above the water and then dive down to catch their prey. Bald eagles have been observed chasing after Common Murres, scoters, grebes, and other seabirds.


While the bald eagle’s diet primarily consists of fish, they also prey on a variety of other animals. Shorebirds are one such group of prey that bald eagles occasionally target. These birds can include sandpipers, plovers, and even larger shorebirds like oystercatchers.

Bald eagles typically hunt shorebirds by flying low over the shoreline and swooping down to grab their prey with their talons. They may also ambush shorebirds by hiding behind rocks or vegetation and waiting for an opportunity to strike.

Shorebirds play an important role in coastal ecosystems and their predation by bald eagles is a natural part of the food chain. However, loss of habitat and other threats to shorebird populations can have a cascading effect on the ecosystem as a whole, highlighting the importance of conservation efforts to protect both prey and predator.

Bald Eagle Diet: Small Mammals

Bald eagles are primarily known for their preference for fish, but they are opportunistic eaters and will consume a variety of prey if available. This includes small mammals.

While not their primary food source, bald eagles will hunt and consume small mammals such as rabbits, squirrels, rats, and even small rodents. They typically capture these animals by swooping down from their perch and grabbing them with their talons. Once captured, they use their sharp beaks to tear apart the prey and consume it.

Small mammals make up a small portion of the bald eagle’s diet, but they can be an important food source during times when their preferred prey is scarce. Additionally, consuming a diverse range of prey can be beneficial for maintaining a healthy diet and avoiding over-reliance on a single food source.

Bald eagles are skilled hunters and capable of adapting their diet to the availability of prey in their environment. This flexibility, combined with their preference for fish, allows them to survive in a variety of habitats across North America.

Carrion and Scavenging

Bald eagles are opportunistic feeders, meaning they will consume a variety of food sources, including carrion. They are known to scavenge for food, feeding on dead animals they come across.

Roadkill is a common food source for bald eagles, as they can easily spot the carcasses while soaring above. They also scavenge around landfills and garbage dumps, feeding on discarded food.

When feeding on carrion, bald eagles will often tear off chunks of meat using their sharp beaks and talons. They have been known to feed on a variety of animals, including deer, rabbits, and even other birds.

Impact on Bald Eagle Diet

While scavenging for food can provide an alternative food source for bald eagles, it is not their preferred method of obtaining food. Pollution and habitat loss can have a significant impact on the availability of their primary food sources, making scavenging a necessary but potentially unreliable option for survival.

In addition, consuming contaminated carrion can have negative health effects on bald eagles, leading to illness or death. Therefore, it is important to maintain a healthy ecosystem for the bald eagle’s survival.
