" Though generally spread over India, the Kupasee is by no means 
common. It is most frequent in woody districts. Its general food 
is insects (chiefly grasshoppers and locusts), lizards, and mice. I 
shot one in Groomsoor, which was devouring the carcass of a dove ; 
this, however, appeared to have been dead some time, and I doubt 
if it was killed by the Kupasee. It often frequents long grass and 
grain-fields, over which it may be seen to hover like the Kestril." — 
(Jerd., Madr. Journ. L. S. X. p. 71.) 
Mr. Hodgson gives the following notice of the manners of this 
bird. " The Chanwa, or Black-wing, quests chiefly in the morning 
and evening, feeding upon small birds, insects, and mice. It does 
not usually seize upon the wing, though its hunting be, for the most 
part, by continuous questing. Commonly, it is seen skimming the 
cultivation like a Circus, occasionally poising itself on the wing for 
the purpose of getting a distincter view of some mouse, small bird, 
or insect which has stirred on its beat, and upon which, when clearly 
perceived, it stoops perpendicularly with the speed of lightning. After 
a while, it will resort to some low roost, and, when relieved, com- 
mence another excursion, or, perchance, sit and watch there for its 
prey. Its forward flight is easy, low, and silent, but very effective 
in evolution when exertion is required to capture such nimble game 
as mice, which constitute its ordinary food. It frequently whips oft' 
insects from the stalks of standing grain, and this feat is, of course,
