How big is an eagle nest?
Nests are refurbished each spring before the eggs are laid, but other material may be added after eggs are laid and even when the chicks are still in the nest. Nests therefore grow through the years. Most nests are about four feet wide and three feet’ or more deep. Nests can get so large that they often bring down the tree they are built in — a record nest made it to twelve feet wide and fifteen feet tall and weighed over 1000 pounds!
