Where does the Dunlin live?

The Dunlin lives in specific habitats and regions. Knowing where, and when, to look improves your chances of a successful sighting.

Biomes

Tundra, coastal wetlands, estuaries, mudflats, sandy beaches, salt marshes, freshwater marshes, agricultural fields (during migration).

Geographic range

Breeds in Arctic and subarctic regions of Eurasia and North America. Winters along temperate and tropical coasts of Europe, Africa, Asia, and North America.

Preferred environments

During breeding, prefers wet tundra with sedges and mosses. During migration and winter, favors intertidal mudflats, sandy beaches, and shallow coastal waters rich in invertebrate prey.

Elevation range

Primarily found at sea level, but can occur at higher elevations in tundra breeding grounds.

Where to look

Field tips

1. Scan large flocks. Dunlins often occur in large, mixed flocks with other shorebirds. Carefully scan these groups for the distinctive bill shape and, in breeding season, the black belly.
2. Observe feeding behavior. Watch how they probe the mud. Their slightly downcurved bill is well-suited for this, and their methodical foraging can be a good identification clue.
3. Check tides. Shorebirds are most active and visible during falling and low tides when mudflats are exposed. Plan your visits accordingly.
4. Use a scope. For distant flocks on large mudflats, a spotting scope is invaluable for picking out individual features like bill shape and plumage details.
5. Listen for calls. Their 'kreep' call is quite distinctive and can help locate them, especially in flight or when obscured by vegetation.

Migration

Long-distance migrant. Breeds in the Arctic and subarctic and migrates south to temperate and tropical coastal areas. North American breeders winter along the Atlantic and Pacific coasts of North America, and occasionally further south. Eurasian breeders winter along coasts of Europe, Africa, and Asia.
