The three-banded plover, or three-banded sandplover (Charadrius tricollaris), is a small wader. This plover is resident in much of eastern and southern Africa and Madagascar, mainly on inland rivers, pools, and lakes. Its nest is a bare scrape on shingle. This species is often seen as single individuals, but it will form small flocks. It hunts by sight for insects, worms and other invertebrates. Three-banded plovers have a sharp whistled weeet-weet call.

Description[edit]

Female incubating
Nest with two eggs

The adult three-banded plover is 18 cm in length. It has long wings and a long tail, and therefore looks different from most other small plovers in flight, the exception being the closely related Forbes's plover that replaces it in west Africa.

The adult three-banded plover has medium brown upperparts, and the underparts are white except for the two black breast bands, separated by a white band, which give this species its common and scientific names. The head is strikingly patterned, with a black crown, white supercilia extending from the white forehead to meet on the back of the neck, and a grey face becoming brown on the neck. The eye ring and the base of the otherwise black bill are red.

The Madagascan subspecies C. t. bifrontatus has a grey band between the bill and the white forehead, and the sides of the head are grey. A genetic study reported genetic differentiation between Madagascar and the mainland population.[2] The sexes are similar, and the juveniles of the nominate and Madagascan subspecies also resemble the adults, although the forehead is brownish for a short time. This species is distinguished from the larger, darker Forbes's plover in that the latter species has a brown forehead and lacks a white wingbar.
