The diet of the lesser sand plover includes insects, crustaceans and molluscs, as well as marine and annelid worms, although it has also been observed eating seeds (5) (6) (7). Foraging either alone or in small, scattered flocks, the lesser sand plover moves about in a characteristic series of short, quick bursts, frequently pausing to lunge at prey (3). During the non-breeding season, flocks of up to 100 or more may form (7).
The lesser sand plover nests in a scrape on bare ground, in bare sand or shingle, sometimes beside bushes or large stones. It has also been known to nest within a cattle footprint (3) (7). The female typically lays three eggs, but it is usually the male that undertakes most of the responsibility for incubating the eggs for the following 22 to 24 days, and is also the primary carer of the young after hatching (3) (5). At the end of the breeding season, migratory flocks form, and depart the breeding grounds from July, returning again from the following February. However, many non-breeding individuals remain in the wintering grounds year-round (5) (7).
