Description
Plate 11 of Birds of America by John James Audubon depicting Bird of Washington. Though ornithologists generally consider that Audubon's "Bird of Washington" was a misidentified juvenile Haliaeetus leucocephalus, a few authors have thought he might have been right to call it a different, significantly bigger, already very rare species http://books.google.com/books?id=jyTEgs1jJpAC&pg=PA159#v=onepage&q&f=false.
Date 1827-1838
