The TAWNY EAGLE (_Aquila fulva_), the largest, strongest, and most
compactly built member of the family, is from two and three-quarters
to three feet in length, and from six and two-thirds to seven feet in
breadth; the wing measures from one foot two inches to two feet, and
the tail thirteen or fourteen inches. The largest of these measurements
applies to the female bird. When the plumage is in its full beauty,
the head and back of the neck are brownish yellow, and the rest of the
feathers of a uniform dark brown; the tail is white, striped, or spotted
with black at its upper portion, the lower half entirely black; the hose
are almost white. Naumann tells that only the two centre tail-feathers
are of equal length, those towards the sides being slightly graduated.
