While the female incubates, the male usually positions himself on a nearby vantage point affording a view of the surrounding area. The family then leaves the nest site and walks to a traditional brooding location, in some cases several miles distant. Currently-utilized brooding grounds are characterized by the presence of alien pasture or lawn grasses, all currently managed to some extent. In most locations, the birds probably also use nearby native shrubs. Families remain on the brooding grounds until the goslings die or fledge.
Adults become very secretive while flightless.
In the summer, Nene congregate in traditional flocking areas. For the Park's population, these include an adjacent golf course, an adjacent cattle ranch, and a cinderfall area whose main attraction appears to be mamaki, a native, berry-bearing shrub. Two of these locations are also brooding grounds. By late summer, distinct pairing reemerges. Although alien grasses grow in both locations, in neither case was there access to actively or passively managed alien grasslands aside from a small area of roadside grasses that appeared to be used infrequently.
