Scientific name: Calidris alba
Profile last updated:
13 Oct 2021
Description
An active, pale wader reaching 20 cm long. The non-breeding adult is pale grey above and white below, with a black patch at the angle of the wing. It has a short, straight, broad-based black bill, blackish-brown wings with broad, white wing-stripes, and short, black legs. In flight, it shows the widest white wing-bar of any sandpiper, on a very dark wing. The forehead and eyebrows are white; the rump and tail have a brown centre and white sides. Elements of the rufous breeding plumage may be visible in some birds just after their spring arrival or before their autumn departure, and in some overwintering birds.
Distribution
A regular summer migrant from Siberia and other Arctic breeding grounds to most of the Australian coastline. It is uncommon to locally common, arriving from September and leaving by May (some may overwinter in Australia). Sanderlings occur along the NSW coast, with occasional inland sightings.
Habitat and ecology
- Often found in coastal areas on low beaches of firm sand, near reefs and inlets, along tidal mudflats and bare open coastal lagoons; individuals are rarely recorded in near-coastal wetlands.
- Generally occurs in small flocks, however may associate freely with other waders.
- Individuals run behind receding waves, darting after insects, larvae and other small invertebrates in the sand, then dart back up the beach as each wave breaks.
- Also feeds on plants, seeds, worms, crustaceans, spiders, jellyfish and fish, foraging around rotting heaps of kelp, at the edges of shallow pools on sandspits and on nearby mudflats.
- Roosts on bare sand, behind clumps of beach-cast kelp or in coastal dunes.
- Breeding occurs in the Northern Hemisphere.

Threats
- Hydrological changes to estuaries and waterbodies may modify or remove important areas of suitable habitat.
- Disturbance to feeding and roosting sites.
- Pollution of estuaries and coastal areas.
- Tourism or agricultural developments reducing coastal and inland habitat areas.
Recovery strategies
A Saving Our Species conservation project is currently being developed for this species and will be available soon. For information on how you can contribute to this species' recovery, see the Activities to assist this species section below.
Activities to assist this species
- Control dogs on beaches and in estuaries.
- Raise visitor awareness of the presence of this and other threatened shorebird species; provide information on how visitors' actions will affect the species' survival.
- Conduct searches for the species in suitable habitat in proposed development areas.
- Manage estuaries and the surrounding landscape to maintain the natural hydrological regimes.
- Protect coastal areas from pollution.
- Protect and maintain known or potential habitat; implement protection zones around recent records.
- Protect foraging and roosting areas from disturbance or inappropriate development.
- Assess the importance of sites to the species' survival, including linkages provided between ecological resources across the broader landscape.
