Eagle
Steppe eagle (Aquila nipalensis).
Bald eagle nests, also known as eyries, are among the largest nests built by any animal. These massive structures are made of sticks and can be augmented annually by the eagles, growing larger over time. While the exact dimensions can vary, bald eagle nests can reach impressive sizes, with some recorded as being up to 2.5 meters (8.2 feet) in diameter and 4 meters (13 feet) deep, weighing over 1 metric ton (2,200 pounds). These enormous nests are typically built in tall trees or on cliffs.1
