Breeding information

Breeding season: Mar - May Eggs: 6 - 9 Incubation period: 23 - 28 days Fledging age: 21 - 28 days

The breeding season of Magpie Geese depends on geographical latitude and weather conditions. In the tropical North of the continent they breed after the end of the rainy season, in the South-east typically in spring, but possibly any time after substantial rainfall.

Male Magpie Geese can have several females lay eggs in their nests.

Nest building: Male(?) Incubation: Male & females Dependent care: Females & male

Nest

"bungobittah", "malunna" = nest [Aboriginal]

Type: Basket Material: Trampled reeds, grass, sedges, rushes Height above ground: N/A

Nests are trampled platforms above shallow water, with some extra vegetation laid on top.

Eggs

"boyanga", "booyanga", "derinya", "dirandil", "koomura", "ngampu", "nooluk", "pateena" = Egg; "dirundirri" = eggs [Aboriginal]; "gawu" = eggs [gamilaraay]

Size: 74 x 50 mm Colour: Creamy-white, later stained brownish Shape: Tapered oval

Behaviour

Social behaviour: Communal Mobility: Nomadic/dispersive Elementary unit: Flock

Note that Magpie Geese, although mainly aquatic birds, do not rest in water overnight. Instead, they roost in high trees, typically River Red Gums or other eucalypts, often along watercourses.

Food, Diet

Like all other geese, ducks and swans, Magpie Geese are vegetarian. Magpie Geese feed on underwater plants. Note that the chicks seen above were sent out to graze on grassland.
