quite close. At other seasons it is never heard to call, except

 Pulchook I flushed a covey of eight or ten, which flew widely 

 scattered, all alighting on the highest trees." 



Eggs. — Said (no doubt correctly) to be pure white, and six to 

 eight in number.

 which are scattered about the district. They feed on insects, 

 for which they scratch amongst the decaying leaves that carpet 

 the ground, seeds and berries of various kinds, and on young 

 shoots.
