Black-winged geese breed from November to January, usually near the edges of lakes, rivers, ponds and swamps. Nests are built in rock crevices, or caves with sandy slopes. Male geese are very territorial. The female goose is lined with plants, and when she lays her eggs, she plucks a lot of her own feathers and places them in the nest. Each clutch lays 5-10 white eggs, which hatch for 30 days. The chicks become sexual early, can swim and do activities the next day after hatching, and are sexually mature at 2 years of age.

Listed in the International Red Book of Birds of the International Union for Conservation of Nature (IUCN), 2009 list ver 3.1.
