18–21 cm (7-8¼ in)

  • back brownish grey
  • underparts white
  • flanks mottled
  • legs dark
  • bill black

Breeding

  • breast, forehead and nape chestnut
  • eye mask black

The female is similar but duller
Winter and juvenile birds lack the chestnut

Similar species

Siberian Sand Plover differ from Tibetan Sand Plover in:

  • Siberian average larger, bill thicker and end blunter, legs shorter
  • flanks are mottled in Siberian but clean in Tibetan
  • in flight: feet protrudes past tail on Tibetan but usually not on Siberian

In breeding plumage

  • Siberian male usually have some white above bill in the "bandits mask" while this is rare in Tibetan
  • female Tibetan rarely have black in auricular area, something usually found in Siberian.

In non-breeding plumage

  • breast band (nearly) unbroken on Siberian, but limited to breast sides in Tibetan
  • pale forehead grades into the crown in Tibetan while demarcation is sharp in Siberian

Compare also with Greater Sand Plover

Greater Sand Plover

Distribution

Is only known to breed within Siberia (the eastern third, also known as Far East Russia. It winters in east Asia from southern Japan and along the eastern coast of [[China} to Greater Sundas, New Guinea, Australia, and in small numbers to New Zealand.
Vagrants have been recorded in Europe, North America, and South America; however, Alaska is likely regularly visited during migration.

Taxonomy

This species and Tibetan Sand Plover were formerly lumped under the name of Lesser Sand Plover (sometimes instead named Mongolian (Sand) Plover).

Subspecies

Clements recognises the following subspecies [1]:

Habitat

Coastal shores, mudflats and fields

Behaviour

Strongly migratory, however, birds in their second calendar year may stay in the wintering grounds.

Breeding

They nest in a bare ground scrape; the clutch consists of 3 eggs.

Diet

Their varied diet includes insects, crustaceans, such as crabs and molluscs and annelid worms on their non-breeding grounds. What they eat during the breeding season is not well recorded.
