Marsh Sandpipers are medium-sized waders with long needle-like bills and very long greenish legs. They are often mistaken for Greenshanks.

Marsh Sandpipers eat mainly worms, insect larvae and bivalve.

wading in water foragingTo find their prey, Marsh Sandpipers may wade up to their bellies in shallow water, walking briskly and steadily, pecking off titbits on the water surface, or sweeping around on the bottoms with their bills. They appear to prefer soft mud.

Wary birds, Marsh Sandpipers usually hunt alone, but on rich feeding sites may gather in co-ordinated groups, or join other waders.

However, they roost in large groups, often with other waders such as Greenshanks. Marsh Sandpipers do not regularly roost in mangroves but are attracted to open clearings in mangroves.

Breeding (April-August): Marsh Sandpipers breed in temperate zones from Southeastern Europe through Russia to Western Siberia and Ussuriland. The courtship song is a repeated tu-ee-u. On breeding grounds, the alarm call is a sharp chip.

Marsh Sandpipers nest around grassy and muddy shores of freshwater pools in steppes and boreal wetlands with lush grassy vegetation. But they may also tolerate brackish water. Nests may be solitary or in loose colonies with the nests about 10m apart. Both parents incubate and raise the young.

Migration: Most Marsh Sandpipers winter in sub-Saharan Africa and in India; others in Europe. Fewer winter in Southeast Asia and Australia. Marsh Sandpipers tend to fly long distances and don’t stop often at passage sites. They usually arrive late and leave early. Non-breeders may stay at the wintering grounds all year, or summer at intermediate sites. They prefer to winter on inland wetlands, both fresh and brackish, sometimes in large numbers of several hundred. In Singapore, they are found on mudflats, sandy shores, ponds, reservoirs and canals.

Status and threats: Marsh Sandpipers are particularly threatened by the overuse of insecticides and herbicides because they tend to forage in cultivated wetlands such as ricefields.
