Nests
Bald Eagles have very large nests and require big, sturdy trees to build them in. The nest tree chosen by a Bald Eagle is often one of the tallest around, is close to the water, and must have enough branches in the crown to support the nest.

Medium-sized sticks are used to give the nest most of its shape and structure; softer plant materials such as pine needles, fresh leaves, and clumps of grass are used for covering the top surface of the nest. Bald Eagle pairs usually return to the same nest year after year and often make the nest a little bit larger with each return visit. After several years of use, nests that were 3 to 5 feet across when first built may reach up to 10 feet across and 15 feet deep.

Eggs
Bald Eagle eggs are off-white in color and about twice the size of a chicken egg. The number of eggs laid, or clutch size, can vary from just a single egg to as many as 3 eggs. The nestlings hatch after a 35 day incubation period.
