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.
In October the annual moult of the birds is completed, so that, clothed in their warm new feathers, they are ready for winter some time before it comes. In the case of the redstart, the bush-chat, most of the wagtails, and some other species, the moult completely changes the colouring of the bird. The reason of this is that the edges of the new feathers are not of the same colour as the inner parts. Only the margins show, because the feathers of a bird overlap like slates on a roof, or the scales of a fish. After a time the edges of the new feathers become worn away, and then the differently-hued deeper parts begin to show, so that the bird gradually resumes the appearance it had before the moult. When the redstarts reach India in September most of the cocks are grey birds, because of the grey margins to their feathers; by the middle of April, when they begin to depart, many of them are black, the grey margins of the feathers having completely disappeared; other individuals are still grey because the margins of the feathers are broader or have not worn so much.
October is the month in which the falconer sallies forth to secure the hawks which will be employed in “the sport of kings” during the cold weather. There are several methods of catching birds of prey, as indeed there are of capturing almost every bird and beast. The amount of poaching that goes on in this country is appalling, and, unless determined efforts are made to check it, there is every prospect of the splendid fauna of India being ruined. The sportsman is bound by all manner of restrictions, but the poacher is allowed to work his wicked will on the birds and beasts of the country, almost without let or hindrance.
