 [350.] Harpy Eagle. TJirasH-tos harpyia. 



Range.— Tropical America; north casually to the Lower Rio Grande Valley in 

 Texas. This accidental straggler to our borders is the largest and most power- 

 ful bird of prey found in America, often reaching a length of nearly four feet. 

 They nest in the highest trees of the largest forests. 

 [35 1]. Gray Sea Eagle. Haliartiis albirilla, 



A common species on the sea coasts of Europe; straggling to southern Green- 

 land, where it nests upon the rocky cliffs. 

 352. Bald Eagle. HaliHCtas Icucoccphalu^. 

 Range. — Whole of North America; most abundant on the Atlantic coast; 



breeds throughout its range. 

 This large white headed and 

 white tailed species is abun- 

 dant in sufficiently wild lo- 

 calities 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 rarelv 

 lay more than two eggs, which are white. Size 2.75 x 2.10. Data.— Mt. Pleas- 

 ant. S. C, nest in top of a pine, 105 feet from the ground; made of large sticks 

 and lined with Spanish moss. Two eggs. Collector, Arthur T. Wayne. 

 352a. Alaska Bald Eagle. Hali^eefufi Icurocrphalus 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 laitl in February and March.
