Birds and Birding's Guide to:Watching THE PLOVER-LIKE BIRDSTHE GULLS AND THEIR ALLIESTHE TRUE PIGEONSThe Indian Green Pigeons(Crocopus) of the Indo-Chinese countries agree with the last in the form of the tail and the yellowish leg-feathers, but differ in having the first three primaries more or less pointed. Of the three species the Bengal Green Pigeon (C. phcenicopterus), a bird about twelve and one half inches in length, has the plumage greenish and grayish, with a well-defined green band at the base of the tail. Although found to some extent in various parts of India, it is only at home in Bengal, while the Green-fronted Pigeon (C. viridifrons), a similar but slightly larger species, is found throughout India and Cochin China, being replaced in the Indian peninsula and Ceylon by the Southern Green Pigeon (C. chlorogaster). The Indo-Chinese countries are also the home of another group of these Pigeons (Osmotreron), numbering no less than nineteen species, which are distinguished from the others just mentioned by having the tibial feathers greenish or whitish instead of yellowish. In the three remaining genera of the subfamily the sheath of the upper mandible reaches the feathers of the forehead. Of these Butreron, with a single species (B. capellei), is found in the Mergui Archipelago, Malay Peninsula, Sumatra, Borneo, and Java. Treron with two forms, is widely spread from the southeastern Himalayas to the Philippines ; and Phabotreron, with nine species is confined to the Philippine Islands. The latter, marked by possessing a tail of only twelve feathers, are handsome small birds under ten inches in length, with a plumage mainlyof chocolate-brown. previous bird species next bird species
