8 THE BIRDS OF THE LUCKNOW CIVIL DIVISION. 
38. —Circaetus gallicus, Gm. Native name—Jal- 
lar (?) 
8th November, Male.—Length, 29°; expanse, 72°; wing, 
22:50; tail, 12°50; tarsus, 3°50; bill, from gape, 2°25 ; weight, 
23 lbs. Irides bright yellow. 
The Common Serpent Eagle is a permanent resident and 
fairly abundant. It frequents open country, and like 4. vindhiana 
may often be seen seated on some solitary tree in its favorite 
resort—low scrub or dhak jungle. Ihave also seen it on the 
open plains, seated on babool and other low trees. 
From the open nature of the country which it frequents, it is 
often difficult to approach, especially in the morning; but after 
it has breakfasted well, and during the heat of the day, it seems 
loath to fly, and may then be easily shot. 
39.—Spilornis cheela, Lath. 
The Indian Harrier Eagle is very common during the cold 
weather, but does not, that I know of, remain all the year round. 
It appears to leave for the hills, or humid submontane tracts, 
about the beginning of April, returning again about October. In 
well-wooded and jungly districts it may be noticed in the morn- 
ings and evenings sailing slowly over the trees and fields, often 
at a great height; but during the heat of the day it generally 
remains inactive, seated near the top of some tall tree, pretty 
well concealed from view. 
40.—Pandion haliaetus, Lin. Native name—Wacha- 
riya and Machi-mar. 
The Osprey is, I believe, a permanent resident, though of this 
I am not quite sure. I have frequently seen it hawking over 
large jhils, but along the Ganges, Gogra, Chowka and Goomti 
rivers it is fairly abundant during the cold weather. It may 
breed in the vicinity of these rivers, though I have never 
found its nest, and possibly it retreats to the rocky torrents of 
the outer Himalayas to breed. During the cold weather it 
may often be seen fishing in the Goomti at Lucknow. 
41.—Polioaetus ichthyaetus, Horsf. 
The Ring-tailed Fish Eagle, like the Osprey, may be met with 
occasionally on large jhils, more frequently on rivers ; but it 
is by no means abundant, and is a wary and difficult bird to 
approach. I have only seen it during the cold weather, and 
then only on two or three occasions.
