Siberian Sandplover

Charadrius mongolus is a small, compact shorebird with a short bill, orange-washed breeding plumage across the face and breast, and pale grey-brown winter plumage. Like other plovers, it forages with a characteristic run-stop-peck pattern, feeding on invertebrates such as small crustaceans, molluscs, and insects found in intertidal sediments. As a migratory species, it plays a role in coastal and mangrove ecosystem food webs, both as a predator of invertebrates and as prey for larger birds and mammals.

The species breeds in parts of Russia and China and migrates along the East Asian-Australasian Flyway, wintering and staging across an extensive range that includes Japan, the Koreas, Taiwan, Southeast Asia, Indonesia, the Philippines, New Guinea, Australia, New Zealand, and numerous Pacific islands. It relies on coastal supratidal zones, marine neritic waters, and subtropical/tropical mangrove habitats for feeding and roosting during migration and winter.

The population is declining, driven by hunting and trapping in parts of its range, coastal habitat alteration linked to dam construction and water management, broader ecosystem modification from land reclamation and development, and disturbance or predation from invasive species at breeding and stopover sites. Habitat shifting associated with coastal development compounds these pressures, particularly at critical staging areas along the flyway.

Conservation efforts include protection of key intertidal and mangrove stopover sites, flyway-level monitoring and tracking studies, and international coordination among range states to manage shared wetland habitats. Some countries have implemented hunting restrictions and habitat protections within coastal reserves.

Given continued loss and degradation of intertidal stopover habitat across its migratory route, combined with ongoing hunting pressure, the species' population trajectory remains negative, and its Endangered status reflects sustained conservation concern.
