366 FALCONIDjE. 



Malayan Peninsula and islands as far as the Philippines, Celebes, 

 and New Guinea. In Tenasserim this bird has been found, 

 though not common, as far north as Amherst. Very little is 

 known of the habits, which apparently are similar to those of 

 other species of Butastur. 



Genus HALIAETUS, Savigny, 1810. 



Bill stout ; culmen straight at the base, then greatly curved ; 

 festoon generally well marked but variable. Nostrils rounded. 

 Wings long ; 3rd quill generally longest, 4th and 5th but little 

 shorter. Tail rounded or cuneate at the end. Tarsus stout, of 

 moderate length, its upper third feathered in front, middle third 

 or more scutate in front. Toes scutate above ; claws moderate in 

 size, not very unequal, grooved beneath. 



This genus contains the Sea-Eagles proper, and is found on most 

 tropical and temperate sea-coasts, except those of South America. 

 Three species are Indian, and they differ somewhat in structure, 

 so that each has been made the type of a distinct genus.
