Canada Goose

Branta canadensis is an introduced goose widespread in New Zealand open country. It differs from greylag goose through its black head and neck with a bold white cheek patch. The body is brown with a pale breast and black neck. The white chinstrap is visible at long range.

It is widespread on South Island lakes, rivers and pasture and occurs locally in the North Island. Canterbury high-country basins hold especially large flocks. It grazes pasture and crops and feeds on aquatic plants. Birds form large flocks and travel between feeding and roosting sites.

New Zealand classifies Canada goose as Introduced. Lake Tekapo and Lake Ellesmere Te Waihora commonly support visible flocks.
