Bald Eagles build the largest nests among all birds in the world. Known as eyries, these nests are four to five feet wide and about two feet deep. They weight up to one ton. Some nests can be double this size. They are made by interweaving sticks and branches, while soft material like grass, feathers, and moss are used inside. Nests are generally positioned on top of large trees in the vicinity of water sources. The eggs are a pale white and shaped oval. Both partners share the task of incubating the eggs for about 35 days. The young ones fledge when they are eight to 14 weeks old.

Ibises generally breed in big colonies, except for some species such as the Black Ibis. The nests are usually built on trees using sticks and leaves. However, in the absence of trees Ibises create their nests in bushes or on grasses on the ground. About two to five eggs are laid by an individual Ibis in a nesting season.

Ibis is known as a wading bird. Two extinct species were not able to fly. However, the existing ones can all fly. Ibises stretch out their neck and legs in flight, while also performing flapping and sailing every now and then. They usually fly in groups by forming a V-shape to reduce wind resistance. The birds can keep up a speed of about 23 miles per hour. It has been observed that some species fly over 1,800 miles during migration.
