(1840) Sphenocercus apicaudus apicaudus (Blyth).
THE HIMALAYAN PIN-TAILED GREEN PIGEON.
Sphenocercus apicaudus apicaudus, Fauna B. I., Birds, 2nd ed. vol. v, p. 100.
This large Green Pigeon is a resident bird from the Murree Hills and Kuman to Eastern Assam in the Himalayas up to at least 8,000 feet, and also in the plains at their feet, whilst it also straggles rather further into and breeds in the plains of Assam and Bengal, In Burma it extends to Tenasserim but, according to Robinson and Kloss, its place is taken in the Malay Peninsula by its near relative seimundi.
The breeding habits of the birds of this genus are the same as those of the birds of the preceding ones, Treron and Dendrophassa, but they are, perhaps, more strictly confined to actual forest and they ascend higher up the mountains. They occasionally place their nests in high hushes or bamhoo-clumps and, still less often, high up in big trees. Their favourite site is in among clusters of branches and twigs in small saplings at heights between 15 and 25 feet and, if these are on the banks of a stream or at the edge of some glade, so much the better.
They are, I think, rather late breeders, though the season is very protracted and many birds have two or three broods. Most eggs are laid in April, May and June, but many breed again in July and August, while I have taken fresh eggs in practically every month of the year.
One hundred eggs average 31.7 x 23.8 mm. : maxima 35.0 x 24.1 and 34.1 x 26.1 mm. ; minima 27.6 x 23.0 and 30.7 x 22.1 mm.
Both sexes incubate and the male does most of the incubation by day. Nest-building seems to take a little longer than it does with Dendrophassa, for though I have seen nests completed in three or four days, most take about a week and some, probably when the female is not ready to lay, take even longer than this.
I believe incubation takes fifteen or sixteen days but have never been able to determine this exactly. It does not take more, however, and may take one or two days less.
