Bald eagles need huge nests so that they have enough elbow room: bald eagles have an average wingspan of between 6 ft. and 7 1/2 ft.
German biologist Carl Bergmann discovered a rule regarding the size of various species and their habitat. Called Bergmann’s rule, it stipulates that members of a species are larger the further they are away from the equator.
Bergmann’s rule holds true according to our bald eagles facts, with the largest bald eagles living in northern climates. Bald eagles with wingspans as large as 8 ft. across have been found in Alaska!
Bald eagles are found throughout North America and Mexico. There are two separate subspecies. The first smaller southern subspecies was discovered by Westerners in 1766, and the second larger subspecies which lives in the north was discovered in 1827.
Cultural bald eagle facts reveal that in native cultures, the large size of the bald eagle reflects its importance for many tribes. Bald eagle feathers are often used as an important part of rituals for native tribes in North America.
