Alfred Edmund Brehm,
Cassell's book of birds; vol. 3
“ The usual roosting-places of these birds are among long grass in deserted fields, or dried stalks of corn, amid the stubble, or among the withered foliage of trees. They will return to favourite roosting-grounds from a considerable distance; but though a whole flock often settles in one locality, they seldom roost very near to each other, and if any one approach, even in the darkest night, will at once rise and take flight. ”
