Distribution

The red-kneed dotterel is native to mainland Australia, Papua New Guinea, and Indonesia, and has occurred as a vagrant in Tasmania, Palau and New Zealand.[2]

Habitat

Mainly margins of shallow ephemeral and permanent freshwater wetlands, occasionally saline wetlands, but rarely tidal wetlands.

Size

The red-kneed dotterel is long-legged and medium-sized (length 17–20 centimetres (6.7–7.9 in), wingspan 33–38 centimetres (13–15 in), weight 40–55 grams (1.4–1.9 oz)).

Food

Arthropods, molluscs, annelids and seeds.

Breeding

The red-kneed dotterel generally breeds from October to January, though it may nest in other months if suitable water conditions exist.[3] It nests on the ground on wetland margins, sometimes using nests of other birds such as hoary-headed grebes.[citation needed] Lays clutch of four cream eggs profusely covered with lines, speckles or blotches. Young precocial and nidifugous.

Conservation

With a large range and no evidence of significant population decline, this species' conservation status is of Least Concern.
