Genus OSMOTRERON

The Green Pigeons belonging to the present genus scarcely differ from Crocopus, except in having the sexes conspicuously distinct in Coloration, and the first three primaries much less attenuated.

The habits of all these Pigeons closely resemble those of Crocopus. They are found in flocks, are fruit-eaters, and always perch on trees, rarely if ever descending to the ground. They have a peculiar, rather melodious whistle. Their flight is rapid, and they are generally wary birds, but when feeding on a favourite fruit they are easily approached and shot. The breeding habits, eggs, and nests are identical with those of other Green Pigeons.

The genus is found in a great part of the Oriental region and in. some of the Austro-Malayan islands. Seven species out of the 17 known have been obtained within Indian limits.
