species inhabiting tropical America, and one of which 
occurs also in the West Indies. The habits of the 
birds of both these genera partake much of the some- 
what sluggish character of the Buzzards, to which 
they are probably more closely allied than they are to 
the Hawks. 
Two of the American Buzzard-Hawks, Asturina 
natterert and Asturina pucherant, have recently been 
figured by Messrs. Sclater and Salvin in their admir- 
able work, entitled ‘‘ Exotic Ornithology,” from speci- 
mens which are preserved in the Norwich Museum. 
The Hawks, properly so called, which form the 
next group for our consideration, are distinguished by 
their short wings, rather long legs, and large tails, to 
which latter peculiarity they are probably in great 
measure indebted for their remarkable power of turn- 
ing rapidly in their course when pursuing their prey, 
which they are thus able to follow amongst trees and 
shrubs in a manner which the longer-winged Kites 
and Falcons are unable to attempt. 
Many of the Hawks are birds of great courage and 
activity, and very powerful in proportion to their size. 
The family of Hawks is represented in almost all 
parts of the world, and is divided into the following 
genera — Leucospiza, Tachyspiza, Urospiza, Accipiter, 
Lophospiza, Astur, Melierax, Micrastur, and Isch- 
noscles. 
The genus Leucospiza contains but two species, 
Nove-hollande and ray, both natives of Australia, and
