This subfamily contains a number of very large Pigeons which somewhat approach the Green Pigeons in their habits generally but in their anatomical characters are nearer the Columbinae. Like the Treroninae they have no cs&ca but like the Columbinae they possess both ambiens muscle and an oil-gland. They are essentially arboreal Pigeons but are not expert climbers like the Green Pigeons and have not got the very broad fleshy feet of those birds, yet they have the soles broader and more fitted for holding than the feet of the Columbinae.
The subfamily is represented throughout India, Burma, East to Polynesia, three genera occurring within our limits.
