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. Its larger and darker-plumaged sister species, Forbes's plover, replaces it in West Africa and in the moist tropics. The two species have largely

breeding ranges. Both species present a distinctively elongated profile, due to their proportionally long tail and wings.


Description

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

extending from the white forehead to meet on the back of the neck, and a grey face becoming brown on the neck. The orbital ring is orange-red, and the base of the otherwise black bill is rosy red in colour. The Malagasy 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. The sexes are similar with respect to plumage and size. Juveniles of the nominate and Malagasy subspecies also resemble the adults, although the forehead is brownish for a short time, and the wing coverts show buff fringes. This species is distinguished from the larger and darker Forbes's plover in that the latter has a brown forehead and lacks a white wingbar.


Breeding

Its nest is a bare scrape on shingle. Egg laying occurs from March to June in the tropics, but mainly (over 70%) from July to October (i.e. late winter to early spring) in southern Africa.
