FALCON. 47 



informed me of the circumstance, added, that he obtained the bird 

 alive, and had kept it above ten years, and that it was either six or 

 seven before the tail became white. Colonel Montagu had one of 

 these for nine years, when it died ; but observes, that the tail feathers 

 gradually became white, though the base remained dusky black for 

 above one third of the length. This was a male, and weighed 

 seven pounds six ounces.

Lesser White-tailed Eagle, Gen. Si/n. i. 39. 



Length 2ft. 2in.; bill, cere, and irides, yellow; plumage dull 

 rust colour above, beneath chestnut, mixed with blackish ; head and 

 neck ash-colour, with a chestnut tinge; tips of the feathers blackish ; 

 tail white; legs yellow; claws black. 



This is supposed to be the bird in its first feathers. In the next 

 stage of growth, it measures in length nearly three feet, and becomes 

 the Cinereous Eagle ; it is by some authors called the Erne, but the 

 inhabitants of the Orknies call the Golden and Black Eagles, and the 

 Osprey, as well as this, by that name.

This is of a large size; the bill large and black; general colour 

 of the plumage deep brown, paler beneath; the wings much darker; 

 rump aud tail very pale ash-colour, nearly white ; legs black. 



Inhabits New Holland, and, from its make and shape, isprobal^ly 

 a farther variety of the Cinereous Eagle.
