Sharp-tailed Sandpiper

A medium-sized shorebird, the Sharp-tailed Sandpiper is distinguished by its rufous-capped crown, streaked breast, and scalloped upperparts that give way to a paler, chevron-marked belly, along with the pointed tail feathers that lend the species its name. It forages by probing and picking at mud and shallow water for invertebrates, seeds, and other plant material, often in loose flocks alongside other shorebirds. As a long-distance migrant, it plays a role in nutrient cycling across the wetland ecosystems it passes through and connects breeding and non-breeding habitats across vast distances.

The species breeds in the Arctic tundra of northeastern Russia and undertakes an extensive migration through East Asia, including China and South Korea, to non-breeding grounds primarily in Australia, with additional records in New Zealand, Indonesia, Papua New Guinea, and occasionally the United States. It relies on a mix of freshwater wetlands, permanent rivers and streams, grasslands, and marine intertidal and coastal habitats, particularly during migration stopovers.

Its decline is driven by the loss and degradation of intertidal staging sites due to coastal reclamation and aquaculture development, particularly along the East Asian-Australasian Flyway. Hunting and trapping in parts of its range, altered water regimes from droughts, and pollution affecting wetland habitats further compound pressures on the population, which is in decline.

Conservation efforts include monitoring of key staging and non-breeding sites, international flyway partnerships aimed at protecting critical intertidal habitat, and site-based protections in parts of Australia and East Asia. Despite these measures, ongoing habitat loss along migratory corridors means the species' long-term trajectory remains uncertain, with continued population decreases expected absent stronger habitat safeguards across its range.
