The Bald Eagle is an opportunistic feeder which subsists mainly on fish, which it swoops down and snatches from the water with its talons. It builds the largest nest of any North American bird and the largest tree nests ever recorded for any animal species, up to 4 meters (13 ft) deep, 2.5 meters (8.2 ft) wide, and one metric ton (1.1 tons) in weight! Full adult plumage is attained during it's fifth year molt. Sexual maturity is attained at the age of four to five years.
There were two Bald Eagles in this nest before my spotting partner spooked one away. Over a two day period we counted 220 Bald Eagles! The sheer sizes of the nests blew me away. 11:30am, Klamath Basin.
