It is often gregarious and will associate with other waders of its own and different species, even when nesting. It is nomadic and sometimes irruptive. DescriptionAdults distinctively marked: black cap or hood from bill, extending below eyes, merging at nape to grey-brown of back. White chin and throat. Broad black band on breast joining nape and also extending to flanks as chestnut stripe. Belly and vent white. Back and mantle grey-brown, mainly black upperwing with white trailing edge. Upper leg, including tarsal joint or “knee”, red. Bill red with dark tip. DistributionThe 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] HabitatMainly margins of shallow ephemeral and permanent freshwater wetlands, occasionally saline wetlands, but rarely tidal wetlands. SizeThe red-kneed dotterel is long-legged and medium-sized (length {{convert|17|–|20|cm}}, wingspan {{convert|33|–|38|cm}}, weight {{convert|40|–|55|g}}). FoodArthropods, molluscs, annelids and seeds. BreedingThe 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|date=October 2010}} Lays clutch of four cream eggs profusely covered with lines, speckles or blotches. Young precocial and nidifugous. ConservationWith a large range and no evidence of significant population decline, this species’ conservation status is of Least Concern.
