Dunlin vs Pectoral Sandpiper

The Dunlin is best identified by its distinctive black belly patch during breeding season and its rufous back, while the Pectoral Sandpiper lacks this feature and instead has a streaked breast sharply contrasting with its white belly. In non-breeding plumage, Dunlins are gray and often seen in large flocks, whereas Pectoral Sandpipers maintain their streaked appearance.

Look for the black belly patch on Dunlins during breeding season. In winter, note the gray plumage of Dunlins compared to the streaked breast of Pectoral Sandpipers. Listen for the Pectoral Sandpiper's hollow hoots during displays.
