Nene have the longest nesting season of any wild goose species; eggs are laid in the winter months from August to April, although most eggs are laid during November-January (2). Females lay eggs in hollows in the ground amongst vegetation; these nests are often found in a 'kipuka' (an island of vegetation surrounded by barren lava) (8). Hens incubate their clutch (usually three eggs) for 30 days (9). Goslings remain flightless for three months, making them particularly vulnerable to predation (4). Adults feed on grasses and fruits of native and introduced plants and give similar calls to Canada geese (4). Unlike other geese, nene do not require open water although they will swim if there is water near to their nest (8).
