It breeds in Australia. The species is closely related to (and sometimes considered conspecific with) the Kentish plover, Javan plover and white-fronted plover.

Description

Red-capped plovers have white underparts and forehead. Their upperpart are mainly grey-brown. Adult males have a rufous or reddish-brown crown and hindneck. Adult females have a paler rufous and grey-brown crown and hindneck, with a pale loreal stripe. The upperwing of Charadrius ruficapillus shows dark brown remiges (flight feathers) and primary covert feathers with a white wingbar in flight. Its length is 14–16 cm and its wingspan is 27–34 cm; and weighs 35–40 g.

Breeding plumage shows a red-brown crown and nape with black margins. Non-breeding plumage is duller and lacks the black margins.[2]

Distribution and habitat

The red-capped plover is widespread in Australia; it is a vagrant to New Zealand, although it bred there for some time in small numbers from 1950–1980.[3] The species occupies a range of coastal and inland habitats, including estuaries, bays, beaches, sandflats and mudflats; inland saline wetlands. It is also found in inland wetland areas with bare ground.

Food
"Nest" with eggs

Mainly small invertebrates, especially molluscs, crustaceans and worms.

Breeding
Female
A chick, adopting a camouflaged position that helps it avoid detection by predators such as gulls and crows.

The red-capped plover is a seasonal breeder on the coasts of Australia, but breeds in response to unpredictable rains inland.[3] The plover nests on the ground close to wetlands; the nest is a small depression in the ground, with minimal or no lining. The clutch of two pale yellowish-brown eggs are speckled with black spots. Incubation period 30 days; incubating is mainly done by the female. Upon hatching, the young are open-eyed, mobile and relatively mature (precocial); and flee the nest (nidifugous).

Conservation

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

gollark: They also have this graph of % in work/study, which is oddly different to the earnings one.
gollark: Possibly. As far as I know medicine courses also are pretty small in size and significantly more government-regulated/managed than other ones.
gollark: Well, sure, the maximum is higher, median is about the same.
gollark: Also, economics isn't MUCH higher, these are box plots.
