The WHITE-THROATED PIGEON, Columba vitiensis, also called the METALLIC PIGEON, comes from Indonesia, the Philippines,
New Guinea and islands around northern Australia. As its name indicates, its plumage is a metallic green/purple with a white throat.
Male and female have similar plumage; juveniles are duller. Subspecies vary slightly.
The SQUATTER PIGEON, Geophaps scripta, comes from north-eastern Australia. As the "phaps" in its scientific name indicates,
it is related to the Bronzewing family and has a small patch of glistening metallic green on its wing.
It has a black and white striped face and white belly below its brown bib. Male and female have similar plumage.
The THICK-BILLED GROUND PIGEON, Trugon terrestris, is a terrestrial pigeon found in tropical and sub-tropical
rainforests of New Guinea. Its thick bill allows it to open fallen fruit and seeds.
(This is not the Thick-billed Ground Dove, Gallicolumba salamonis, which became extinct in the 1900s).
The BARE-EYED MOUNTAIN PIGEON, Gymnophaps albertisii, also called the PAPUAN MOUNTAIN PIGEON, lives in mountain forests of New Guinea
up to altitudes of 3,350 metres.
