These birds leave the forest, where they hide during 
day, at 6 p.m. exactly. Usually flying very high they follow 
a valley to seek their feeding places, uttering all the 
time their call note, which can be heard at a great distance. 
’ It sounds like: 
Then they descend to a lower level where they can 
expect a good catch, e.g. above a ricefield, etc. Here they 
flit to and fro, and half an ‘hour later they return to their 
hiding places, their crops being chokeful of insects. Some- 
times they return again in the morning at daybreak. 
‘Their flight is very peculiar and quite different from 
any other birds | know ; very irregular and with many 
zigzags ; from time to time they raise their wings so that 
they form a right-angle and hold them so motionless for 
some time, as they glide through the air. 
Suddenly they interrupt their flight by jerky crochets 
and turns, making it very difficult to hit them, although the 
smallest size of shot will bring them down, just like snipe. 
At Balun I observed every evening some thirty birds coming 
down the valley ; they were so regular in their coming and 
going that I used to set my watch after them. In the time 
of the Mahomedan fasting the villagers, who possess no 
watches, know by the arrival of the birds that it is time 
to break their fast.

The species frequents the neighbourhood of the forest, 
and flies very low late in the afternoon. It is most difficult 
to shoot as it has a very irregular flight.
