As it walks to and fro, it frequently flirts the head and tail, but not so markedly as the Pea-dove. If flushed, it betakes itself to a low tree not far off, whence, if unmolested, it is soon down again. Often when seen in the woods, it runs a few yards, and then rises to fly, but as if trusting less to its powers of flight than to those of running, alights again immediately, and runs swiftly off among the bushes. It has no regular roosting-place, often spending the night on a stone, or a log, or a low bush that happens to be near the spot where it was feeding at nightfall. This is not the case with the other Doves. The aspect and air of the Whitebelly are unlike those of its kindred. Its round head, the prevalence of light hues, and its height upon the legs, contribute to this peculiarity. Essentially a ground-pigeon, its length of tarsus enables it to run with ease and celerity; perhaps more rapidly than any other of the family. Unlike the tree-doves, the Whitebelly usually builds in rather a low situation; often a logwood, a favourite tree with this, and the Whitewing. If in the large woods, one of moderate height is chosen. The nest consists of a few loose sticks, with some leaves in the centre; the eggs are white.
