  • Large, conspicuous black patch on underside during breeding season
  • In winter, chest is dully streaked with brown and underside is a dusty off-white
  • Bill is long, black, and droops downward at the tip
  • White eye-stripe usually visible, though not always well-defined
  • Black legs
  • Juvenile:  dull rusty wash predominates above, chest buffy, underside faintly spotted

Similar Species: The winter spotted sandpiper is browner, with yellow legs and a pale-based bill.

Voice: The dunlin’s only note is a highly nasal dreezp!

Habitat: Dunlins are usually found only at the seashore, where they frequent tidal flats and breakwaters.  In the far north of their range, they breed on the open tundra.

Range: The dunlin can be seen along most of the Atlantic coast during the winter, and they breed in the far north of Canada near the Arctic circle.

Interesting Facts: Dunlins who breed in Alaska have been known to move west when they fly south for the winter, sometimes arriving in Japan or eastern China.
