Subfamily TRERONINAE

These are the Green Pigeons of India, and may be at once recognized by their yellowish-green plumage, often with patches of lilac or chestnut on the mantle. There is always a bright yellow band, sometimes two, on the larger wing-coverts ; there are fourteen tail-feathers ; the tarsus is considerably shorter than the middle toe without claw, and has its upper portion covered with feathers. The soles of the toes are much expanded, being considerably broader than the toes themselves. The short tarsus and broad soles are adaptations for perching, and are found in Pigeons that live chiefly or wholly on trees.

This subfamily inhabits the tropical and subtropical regions of the Old World. Five out of seven genera are Indian. All are purely fruit-eating birds, living on trees, and generally keeping in flocks; and all are good birds for the table.
