Rarely taking to the air, the St Helena plover is most commonly found in pairs, or occasionally in small groups of non-breeders, foraging in grassland or in semi-desert areas for invertebrates such as beetles and woodlice (3) (4).
Breeding takes place throughout the year, but the majority of breeding activity occurs during the dry season, from late September to January. The exact timing of this breeding peak may vary considerably from year to year, according to environmental conditions (4). The nest consists of a simple scrape in the ground, where a clutch of two eggs is laid, although single-egg clutches are occasionally seen. The eggs and nestlings suffer from high levels of predation from introduced species such as feral cats, rats and the Indian myna (Acridotheres tristis) (4), hence this species commonly lays a replacement clutch if the first clutch is lost (2). After leaving the nest, juvenile St Helena plovers disperse throughout the island in small flocks (2).
