3. A pair of bald eagles from Florida is credited for building the largest nest that measures six meters deep, four meters wide and weighs nearly three tons.
4. The bald eagle is not actually bald. It got its name from “piebald” meaning spotty or patchy which aptly describes the bald eagle with its brown body and white head and tail. In addition, the word bald is actually derived from an Old English term “balde” meaning white.
5. Did you know that bald eagles have remarkably good eyesight? They can see four to seven times better than people. They can see things from a very far distance of up to one mile. This characteristic enables them to search for their food high up in the sky or from a perch in a tree or cliff.

7. Bald eagles breathe with their lungs and air sac system. They breathe through the openings on the side of their beaks called “nares.”
8. Eagles do not have vocal cords. They make a high-pitched, shrill squeaking and screeching sounds via the air that passes the bones in their neck. Specifically, the sound is created the area where the windpipe is separated going to the lungs. The eagle’s calls are made to deepen the bond between married eagles or to warn predators not to pass their territory. The screaming sounds of eagles you hear in the movies are actually those of the red-tailed hawk used to provide a dramatic effect.

The bird’s beak has a hook at the tip with an upper mandible behind it used to slice through thick skin. The beak has other uses apart from eating. Though a strong and sharp weapon, it can take care of its mate’s feathers or feed an eaglet.
