Subfamily CARPOPHAGINAE

This subfamily contains the largest Indian species of the order, known in India as Imperial Pigeons. Like the Treroninae, they are fruit-eaters and live entirely in trees, and they have similar feet; but they differ greatly from the Green Pigeons and approach the Columbines in plumage and also in anatomy, as they have an oil-gland and an ambiens muscle. They are also distinguished by laying in general only a single egg, a peculiarity repeated, as will be noticed presently, by a genus of the Columbine subfamily. The tail-feathers are 14 in number.

The bill is proportionately larger than in Treroninae, and the gape very wide, enabling these pigeons to swallow fruits of considerable size. All are forest birds; and the whole group, which ranges from India to Polynesia, is chiefly insular in its Distribution. Even of the six species here included, two are found, within our area, only in the islands of the Bay of Bengal.
