This large form of Black Drongo is resident in the Himalayas from the foot-hills up to at least 5,000 feet, from the North-West Frontier to Eastern Assam, North of the Brahmapootra. Birds resident and breeding in the plains immediately adjacent to the hills in Behar and Northern Bengal are very large and must be included in this race, but the birds breeding in Behar Southwards and in all Bengal except the extreme North are of the preceding race. Even birds taken by me breeding as far North as Dacca and Mymensingh were too small for the present race. On the other hand, birds from East of the Bay of Bengal, the hills of South Assam, Manipur, North Chin Hills, North Kachin Hills and North Shan States all appear referable to the Northern hill race. The limit of its breeding in the Himalayas appears to be about 7,000- feet, at which elevation Dodsworth obtained it in the Simla States.
There is nothing one can add as regards the breeding of this bird to what has been already written of the preceding race except that it is not quite so exclusively an open country, humanity-loving bird. The nest may occasionally be taken in thin forest or in open, well-wooded country at considerable distances from all human habitation or cultivation.
The breeding season is almost exclusively May and June, but I have seen a few nests in the Khasia Mills in April and Osmaston also took a nest in the United Provinces Terai on the 21st of this month.
I have only been able to measure sixty eggs indisputably those of albirictus. These average 27.1 x 19.8 mm. : maxima 29.4 x 21.1 mm. ; minima 23.6 x 18.0 mm.
