About the White-rumped Sandpiper

The White-rumped Sandpiper is another small, long-winged "peep" that rewards a careful eye, distinguished at rest by wingtips that project past the tail and, most reliably, by a clean white band across the rump that flashes when the bird flies — a mark shared by no other regular peep in Michigan. Gray-brown above and streaked on the breast and down the flanks, with black legs and a slightly drooped bill showing a reddish base, it forages steadily on mudflats and marsh edges, often wading into shallow water.

It is a champion long-distance migrant, breeding on the high Arctic tundra and wintering at the southern tip of South America, one of the longest migrations of any bird, and it tends to pass through Michigan late — often lingering into late spring and returning in a protracted fall window. Never common in the state, it is a regular migrant that turns up among flocks of other small sandpipers. Catching the white rump as a bird flushes is the surest way to confirm this subtle but rewarding shorebird.


Diet

Aquatic insectsSmall invertebratesSeeds

Feeds on aquatic insects, small invertebrates, and some seeds, probing and picking on mudflats, marsh edges, and shallow water, often wading in to forage. It gathers energy for its very long migration by feeding steadily at stopover wetlands and shorelines.

Questions birders ask

What is the best mark for a White-rumped Sandpiper?

A clean white band across the rump, visible when the bird flies — no other regular Michigan peep shows this. At rest, long wingtips projecting past the tail and streaking down the flanks also help.

Why does it migrate so far?

It breeds on the high Arctic tundra and winters at the southern tip of South America, one of the longest migrations of any bird. This extreme journey passes through the continental interior, including Michigan.

When does it come through Michigan?

It is a relatively late migrant, often lingering into late spring and returning over a protracted fall window. Never common here, it turns up among flocks of other small sandpipers on mudflats and marsh edges.
