AQUILINE. 



The species of this genus are found in India, its archipelago, Australia, and South America. They are generally 

 noticed in the neighbourhood of the sea or inland lakes, over which they fly at a great elevation, seeking their prey, 

 which chiefly consists of fish. Their flight at first, after rising, is heavy, but when once fairly on the wing easy and 

 powerful, rising to a great height by large and graceful sweeps.

Helotarsus Smith.* 



The characters in common with Haliaetus ; but the Tail is exceedingly short and truncated. Tarsi 

 short, covered entirely with small scales, those posteriorly the largest. Toes long, the bases of all covered 

 with small scales, and the tips with transverse ones. 



This singular-looking bird is peculiar to Southern Africa, where it is usually seen in pairs, feeding on all sorts of 

 carrion, and will attack young antelopes and weakly sheep. It possesses a remarkable habit of flapping its wings whilst 

 in the air, so as to be heard at a great distance.

Haliastur Selby.f 



Most of the characters are similar to those of Haliaetus ; but the Tarsi are covered in front with 

 large obliquely placed scales, posteriorly with large irregular scales, and the sides with small ones. 



Australia and tbe continent of India are the countries of the few species of this genus. They are much on the wing, 

 sailing in the neighbourhood of water, at a moderate height, seeking various kinds of prey, as fish, reptiles, crabs, birds, 

 and even carrion, which they pounce upon in the same manner as the birds of the foregoing genera. The typical 

 species has been observed to seize insects off trees or standing grain ; these, and its food generally, if not heavy, it often 

 devours in the air.

* Dr. Andrew Smith established this genus in April, 1830; while, in November of the same year, M. Lesson proposed Terathopius 

 for the same type.
