(1843) Ducula badla insignis Hodgs.
THE NEPAL MAROON-BACKED IMPERIAL PIGEON.
Ducula badla insignis, Fauna B. I., Birds, 2nd ed. vol. v. p. 203.
This Pigeon occurs from Nepal in the West to Eastern Assam in the Himalayas between the foot-hills and 6,000 feet, but principally between 2,000 and 4,000 feet, while in Eastern Assam it breeds freely in the plains to some distance from the hills.
In the Khasia Hills, though adjoining the Cachar Hills and South of the Brahmapootra, the form found is much nearer insignia than griseicapilla, whereas that obtained in the Cachar Hills is nearer the latter bird. This is explained by our geologists, who prove that at one time the Khasia Hills were separated by the Brahmapootra from Cachar. In many instances the fauna is consequently found to be more nearly allied to that of the Northern Himalayan than to that of the Southern hills.
In ‘Indian Pigeons and Doves’ (p. 101, 1913) I thus wrote of the breeding of this bird :—“The breeding season of this Pigeon on the north-east frontier of India, from Nepal to Sadiya and in the Khasia Hills South of the Brahmapootra, appears to commence when the rains break and to last through July and August, hut I have seen its nest, containing a young bird, in March, so it is possible they have two broods, the first from February to March and the second during the rains.
“The nest is of the usual description—a rough platform of sticks with practically no depression in the middle, and measuring anything from 9 inches to a foot in diameter by some two to four inches thick. There is no lining of any description whatever, though some of the smaller, more pliant twigs seem to form the uppermost part of the centre of the neat. The majority of the sticks and twigs of which the nest is composed appear to have been tom living from the tree, but there are also a few pieces of twig and stick which were evidently dead long before the bird made use of them.
“As a rule the nest is placed at no great height from the ground some twenty to twenty-five feet—in small saplings, but I have seen nests as low down as 12 feet, and one or two at heights over 40 feet. No attempt is made to place the nest in a concealed position, so that with the sitting bird it can usually be seen from some distance. All the nests I have taken have been in the interior of evergreen forest, but often the site selected is one near some natural clearing or opening and, occasionally, is one by some village track.
“Tbe number of eggs laid is never more than one and, though on one occasion I took two eggs from the same nest, it is probable that they were laid by two hens.”
There is little I can add to this. Like all Imperial Pigeons both sexes incubate and both build the nest, each fetching materials and incorporating them m the nest.
Twenty-two eggs average 46.2 x 33.5 mm. ; maxima 49.1 x 36.1 mm. ; minima 42.4 x 30.3 mm.
