ON A SPECIES. 



coverts, regularly and equally crossed with white and black-brown 

 throughout : irides, orange yellow : cere and orbits, and naked space 

 between the eye and the bill, full clear yellow ; bill, leaden-blue, with a 

 black hook : legs, obscure dirty yellow : habitat, same as the preceding. 



This species is said by the Nipalese to feed on fish. I myself have 

 seen it frequently perched on rocks and trees, overlooking streams that 

 were full of fish. But I never saw it attempt to catch them. I have seen 

 it seize pigeons, and one of my specimens had a small innocuous kind 

 of snake taken out of his throat after he was killed. It ordinarily soars 

 very high : and the male and female are almost constantly together. The 

 female differs from the male chiefly, in having a smaller crest and less full- 

 bodied colours. Proportions, size, and weight as follows :
