The term 'Bald Eagle's Nest' is often referred to as an AERIE, which is a five-letter word. An AERIE is the nest of a bald eagle, which is typically built high up in a tree or on a cliff. Bald eagles are large birds of prey that are native to North America and are known for their distinctive white head and tail feathers. The nests are usually made from sticks and twigs and can be quite large, sometimes reaching up to four feet in diameter.
