BIRDS OF PREY 
[351.] Gray Sea Eagle. Haliceetus albicilla. 
A common species on the sea coasts of Europe; straggling to southern Green- 
land, where it nests upon the rocky cliffs. 
352. Bald Eagle. Haliceetus leucoceplialus 
leucocephalus. 
White 
Bald Eagle 
Range. — Whole of North America; most abundant on the Atlantic 
coast; breeds throughout its range. This large white-headed and white-tailed 
species is abundant in sufficiently wild localities along the Atlantic 
coast. It only attains the white head and tail when three years old, 
the first two years, being blackish. It is about 34 inches in length 
and expands about seven feet, never over eight feet, and only birds of the second 
year (when they are larger than the adults) ever approach this expanse. 
Their food consists of fish (which they sometimes capture themselves, but 
more often take from the Osprey), carrion, and Ducks, which they catch in 
flight. Their nests are massive structures of sticks, in the tops of tall trees. 
They very rarely lay more than two eggs, which are white. Size 2.75 x 2.10. 
Data. — Mt. Pleasant, S. C., nest in top of a pine, 105 feet from the ground; 
made of large sticks and lined with Spanish moss. 
352a. Northern Bald Eagle. — Haliceetus leucocephalus alascanus. 
Range. — Alaska. This sub-species averages slightly larger than the Bald 
Eagle, but never exceeds the largest dimensions of that species. Its nesting 
habits and eggs are the same, except that it more often builds its nests on rocky 
cliffs than does the Bald Eagle. The eggs are laid in February and March.
