Little ringed plover
Template:Short description Template:Speciesbox The little ringed plover (Thinornis dubius) is a small plover native to the Old World. It has mostly brown upperparts, a black neckband and a black mask around the eye with a noticeable yellow eyering. Its forehead, belly and the rest of the breast are white. A migratory species, it breeds in open gravel areas near freshwater, including gravel pits, islands and river edges. Its diet consists mainly of insects and worms, which it forages for in muddy areas.
Taxonomy
The little ringed plover was formally described in 1786 as Chadrius dubius by the Austrian naturalist Giovanni Antonio Scopoli.<ref>Template:Cite book</ref> The specific dubius is Latin meaning "doubtful", "uncertain" or "dubious" since French naturalist Pierre Sonnerat in 1876 had thought this bird might be just a variant of the common ringed plover.<ref>Template:Cite web</ref> The little ringed plover is now one of seven plovers placed in the genus Thinornis that was introduced in 1789 by Johann Friedrich Gmelin.<ref name=avilist>Template:Cite web</ref> The genus name combines the Ancient Greek this meaning "beach" or "sand" with ornis meaning "bird".<ref>Template:Cite web</ref>
Three subspecies are recognized:<ref name=avilist/>
- T. d. curonicus (Gmelin, JF, 1789) – breeds Palearctic from Scandinavia southward to northern Africa, eastward across Russia to Sea of Okhotsk and Ussuriland, southward through Middle East and eastward to Japan and Taiwan; winters to Africa and southern Asia
- T. d. jerdoni (Legge, WV, 1880) – India to southeastern Asia
- T. d. dubius (Scopoli, GA, 1786) – Philippines to New Guinea and Bismarck Archipelago

Habitats and range
Their breeding habitat is open gravel areas near freshwater, including gravel pits, islands and river edges across the Palearctic including northwestern Africa. They nest on the ground on stones with little or no plant growth. Both males and females take turns incubating the eggs.
They are migratory and winter in Africa. These birds forage for food on muddy areas, usually by sight. They eat insects and worms.
Conservation
