Behavior & Characteristics

Knowing the behavior and characteristics of Bald eagles will help you understand them better. Bald eagles show the following behavior and characteristics:

Body & Feathers

The body of a female bald eagle is almost a quarter bigger compared to its male companions.

Nests

Bald eagles love to stay near their food source. That’s why most of their nests are found near open water bodies. This is also the reason why you might encounter bald eagle nests in some unusual places.

The nest of a bald eagle tends to be quite big. The width is somewhere between 4 to 6 feet, and it can weigh over tons. The total weight changes over the years as new layers get added each year.

These nests consist of sticks, leaves, and some occasional rocks and stones.

Mating

They begin to breed when they are 4 years old. It begins in early winter and ends in late spring. Bald eagles choose their partners for life and spend their life with each other unless one dies.

When their mating season starts, they will start to isolate themselves and only go out of their nests when they are hungry.

Calling Sound

You can expect to hear them call out during the mating seasons or when they are facing any sort of threats or when they are feeding their children.

Hunting Style

Bald eagles have superior eyesight, which allows them to notice their prey from a large distance. Once the target (fish) is acquired, they strike swiftly and grab their prey with their talons.

Their preferred attacking option is with their talons, but they will use their beaks if the prey is small or they are hunting on low water bodies.

Aggressiveness

Bald eagles are extremely social compared to other species, like the white-tailed eagle. They only hunt fishes that get closer to the surface, so unless they are provoked, they won’t attack people or animals.
