In the early morning and at eventide, the crow-pheasants give vent to their owl-like hoot, preceded by a curious guttural _kok-kok-kok_. The young ones, that left the nest some weeks ago, are rapidly losing their barred plumage and are assuming the appearance of the adult. By the middle of November very few immature crow-pheasants are seen. Migration and moulting are the chief events in the feathered world at the present season. The flood of autumn immigration, which arose as a tiny stream in August, and increased in volume nightly throughout September, becomes, in October, a mighty river on the bosom of which millions of birds are borne. Day by day the avian population of the _jhils_ increases. At the beginning of the month the garganey teal are almost the only migratory ducks to be seen on them. By the first of November brahminy duck, gadwall, common teal, widgeon, shovellers and the various species of pochard abound. With the duck come demoiselle cranes, curlews, storks, and sandpipers of various species. The geese and the pintail ducks, however, do not return to India until November. These are the last of the regular winter visitors to come and the first to go. The various kinds of birds of prey which began to appear in September continue to arrive throughout the present month. Grey-headed and red-breasted flycatchers, minivets, bush-chats, rose-finches and swallows pour into the plains from the Himalayas, while from beyond those mountains come redstarts, wagtails, starlings, buntings, blue-throats, quail and snipe. Along with the other migrants come numbers of rooks and jackdaws. These do not venture far into India; they confine themselves to the North-West Frontier Province and the Punjab, where they remain during the greater part of the winter. The exodus, from the above-mentioned Provinces, of the bee-eaters, sunbirds, yellow-throated sparrows, orioles, red turtle-doves and paradise flycatchers is complete by the end of October. The above are by no means the only birds that undergo local migration. The great majority of species probably move about in a methodical manner in the course of the year; a great deal of local migration is overlooked, because the birds that move away from a locality are replaced by others of their kind that come from other places. During a spell of exceptionally cold weather a great many Himalayan birds are driven by the snow into the plains of India, where they remain for a few days or weeks. Some of these migrants are noticed in the calendar for December.
