Field Notes
Description:
"The nest is the largest of any bird in North America; it is used repeatedly over many years and with new material added each year may eventually be as large as 4 meters (13 ft) deep, 2.5 meters (8.2 ft) across and weigh 1 metric ton (1.1 short tons);[2] one nest in Florida was found to be 6.1 meters (20 ft) deep, 2.9 meters (9.5 ft) across, and to weigh 3 short tons (2.7 t). This nest is on record as the largest tree nest ever recorded for any animal. Usually nests are used for under five years or so, as they either collapse in storms or break the branches supporting them by their sheer weight. However, one nest in the Midwest was occupied continuously for at least 34 years without interruption."
Habitat:
Top of a tall tree outside town. "The nest is built out of branches, usually in large trees found near water. When breeding where there are no trees, the Bald Eagle will nest on the ground, as has been recorded largely in areas largely isolated from terrestrial predators, such as Amchitka Island in Alaska."
