Bald eagle nests are not made of rocks and mud. Instead, they are constructed primarily from sticks and branches. These massive structures are usually built high in tall trees and can measure up to 10 feet wide and 6 feet deep.
Bald eagles often reuse the same nest year after year, adding new material each breeding season. Over time, these nests can become enormous, weighing hundreds of pounds as generations of eagles continue to expand and maintain them.
