Verhalten

The thick-billed ground pigeon usually forages alone, but is sometimes seen in pairs. It is generally shy, staying mainly on the ground and running away into the undergrowth when disturbed, but launching itself vigorously into the air with rapidly beating wings when it feels threatened. It flicks its tail downwards frequently as it walks. It feeds on fruits and seeds that have fallen to the ground. It picks up fruit with its beak and hammers it on the ground to split it, exposing and eating the seeds. Small items are swallowed whole. It sometimes visits the display arenas of the magnificent bird-of-paradise in order to forage for regurgitated seeds.<p>This bird roosts at night on low branches. Breeding seems to take place at any time of year, with nests having been found between February and October. The nest is a hollow in the ground, perhaps concealed between the buttress roots of a large tree. It may be unlined or may incorporate a few twigs or leaves, or may be rather more elaborate. A single white egg is laid and is incubated by both parents, the male routinely sitting during the daytime. The fledged chick stays in its parents' territory for about a month.
