Kakīānau/Black Swan Cygnus atratus

Native. Not threatened.

 

A large black bird (1.3m in length), the Black Swan has white wingtips which can be seen when flying. The red beak has a white band near the tip. It flies with slow wing beats, its neck outstretched, landing heavily on water and needing a good, splashing runoff to get airborne again.

 

The Black Swan is vegetarian and feeds mostly on aquatic plants, by reaching down into the water with its long neck. When water levels are too high for it to reach the plants it normal feeds on it resorts to pasture and causes problems for farmers. It's usually found on lakes and other wide areas of fresh or brackish water, but non-breeders also inhabit estuaries. It's usually seen in flocks, the members of which communicate with low honking sounds.

Females are smaller than males while juveniles are grey with black feathers coming through as they age. Parents are fiercely protective of their grey fluffy bundles so be warned.

Kuihi/Canada Goose Branta canadensis

Introduced, Not assessed.

 

This large North American goose was first introduced to Aotearoa New Zealand in 1905 and soon spread throughout.

As these geese are grazers they are frequently seen in pastoral areas but also inhabit lakes, rivers and coastal areas, especially after the moult as these provide much security as they are unable to fly for several weeks. They are considered pests in some areas.

Males are much heavier than females weighing up to 8.5 kg with females several kg lighter. Their plumage is quite distinctive with the neck and head coloured black with a white cheek patch which stretches to just under the chin. Upperparts are brown while underparts are either white, a lighter shade of brown or a mixture of both. Juveniles lack the intensity of colour while goslings are a yellowish grey colour. They are noisy birds, especially when flying in the classic V formation.
