The purple-winged ground-dove has a highly specific diet, mainly consisting of bamboo seeds (2) (4). As a result, this species is almost always encountered foraging or breeding in patches of flowering or seeding bamboo, and must undertake seasonal movements to follow bamboo flowering events (2). These events take place simultaneously within local stands of bamboo and persist for a number of years before a mass die-off occurs, after which, another mass flowering may not occur for around 15 to 60 years. Depending on such an unpredictable and ephemeral food supply presents difficulties for this species, especially in terms of meeting the energetic demands of breeding (4). In order to overcome this challenge, when bamboo seed supplies are limited or absent, the purple-winged ground-dove will also take fruit and other varieties of seed (2) (4).
The purple-winged ground-dove appears to breed during the Austral summer, with courtship calls recorded from November to February (2). While little else is known of its reproductive biology, closely related species usually lay a clutch of two eggs, with an incubation period of around 14 days (3)
