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.
