After the breeding season the young and old birds feed together in the pastures, where they unite with other families; and the flocks thus formed, as they increase in size, extend their wanderings over the surrounding country. Like rooks, they have favourite roosting-places, to which they return annually; these are reed and osier beds, thickets of holly and other evergreens, and fir-plantations. But they are not so constant in their attachment to one locality as the rook. They are more vagrant in their habits, and shift their ground, and migrate, and their numbers may vary greatly from year to year in the same district. In a district where they are abundant, they are seen at the end of each day gathering from all directions to the roosting-place; and it is then that the ‘cloud of starlings’ may be seen at its best, and it is certainly one of the finest sights that bird life presents in England. At intervals, after the birds have been steadily pouring in their flocks for a couple of hours, the whole vast concourse rises, and, seen from a distance, the flock, composed of tens and hundreds of thousands, may then be easily mistaken for a long black cloud suspended above the wood. In a few moments it is seen to grow thin, as the flock scatters, until it almost fades away. Suddenly it darkens again; and so on, alternately, the form, too, changing continually, now extending to an immense length across the sky, like a long bar of vapour, and now gathered into a huge oval or oblong black mass; and by-and-by the cloud again empties itself into the trees, and the sky is clear once more. These evolutions are repeated many times, until, as the evening draws on, the birds finally settle down in their places, but not to sleep; for an hour longer the wood is filled with an indescribable noise--a tangle of ten thousand penetrative voices, all together whistling, chattering, scolding, and singing. We have but one starling; an allied species, the beautiful rose-coloured pastor (_Pastor roseus_), which breeds in Western Asia, is an irregular visitor to all parts of England. Chough.
