New Zealand Game Bird Habitat Collection – Grey Duck

The grey duck (Anas superciliosa) is a species native to New Zealand, but due to competition and hybridisation with introduced mallard species, there are no definitive population numbers for pure grey ducks.

The grey duck, which is also known as the parera, is commonly found in remote, shallow wetlands and streams with extensive riparian cover. They tend to be found in singles and in pairs in the wild (although can be found in flocks of mallards too) and are easily spooked.

The male and female are similar in appearance, with the male being slightly larger than the female. Both sexes have brown feathers that range from dark brown to light brown; the head is a lighter brown with a black crown and two distinctive black facial stripes.

The grey duck has a grey beak, khaki legs and an iridescent green speculum with a pale underwing. Both the male and female can be easily confused with the female mallard due to their similarities in appearance.

The grey duck nests from around September through to December and is seasonally monogamous. The females lay and incubate the eggs and raise the ducklings, while the males tend to defend the territories to protect the females.

The females typically lay eight to ten eggs in a season, which incubate for 26 to 29 days. The ducklings accompany the female duck for around seven to nine weeks and can breed in their first year.
