Macropygia Swainson. Glass. B., ii, p. 348 (1837).
Type, Columba phasienella Temm.
This is a very well-marked genus, the long tail exceeding the wing in length and being greatly graduated; the tarsus is feathered for the greater part of its length, the toes long with broad arboreal soles; the feathers of the rump are spinous and the tail-coverts elongated. A remarkable feature in this genus is the curious barring on the plumage of the adult male or female, in one species, unchall, the lower plumage is barred in the adult female but not in the male; in rufipennis the barring on the adult sexes is reversed, whilst in ruficeps neither sex is barred when adult.
The genus contains a great number of species and subspecies which extend from Eastern India and the Indo-Chinese countries into South Australia.
