A crepuscular bird, the Australian painted snipe has an omnivorous diet, feeding on vegetation, seeds, insects, worms, molluscs, crustaceans, and other invertebrates. While it will occasionally forage over mudflats and other open areas, it generally remains in dense cover while feeding. During the day, the Australian painted snipe rests quietly under dense cover, such as grass and reeds (7).
The Australian painted snipe is generally seen singly or in pairs, although flocks may form during the breeding season, when adults sometimes congregate in loose gatherings around a group of nests (7). Breeding is thought to occur in response to weather conditions rather than during a particular season, as there are records of the Australian painted snipe breeding in every month (7). However, in southern Australia breeding is typically recorded between August and February, while it is usually earlier in the north (6).
The female Australian painted snipe is thought to mate with more than one male. Three to four eggs are laid, and it is the male that is responsible for incubating the eggs and caring for the chicks (6).
