Dunlin

The dunlin (Calidris alpina) is a small, plump, migratory shorebird belonging to the sandpiper family (Scolopacidae).

It's characterized by its slightly drooping bill, short legs, and variable plumage that changes dramatically between breeding and non-breeding seasons.

In breeding plumage, adults display a distinctive black belly, rusty back, and patterned head. Outside of breeding season, they are generally a greyish-brown above and white below. Dunlins are commonly found in coastal wetlands, mudflats, and salt marshes worldwide. Their diet primarily consists of invertebrates, such as small insects, worms, and crustaceans, which they find by probing in the mud or sand.

They are known for their characteristic flocks and complex flocking behaviour during migration and feeding.

The dunlin’s conservation status is generally considered of 'least concern', although some populations face threats from habitat loss and climate change.

Dunlin meaning with examples

• The flock of dunlins wheeled over the mudflats, a swirling cloud of grey and white feathers against the overcast sky. They were seeking the rich buffet of invertebrates below the surface, which are their primary food source.
• During the winter, the dunlins' plumage becomes a muted grey-brown, making them blend seamlessly with the coastal landscape, however a keen eye can spot their unique shape when scanning for wildlife.
• The young bird, in its juvenile plumage, diligently probed the shoreline with its bill, alongside the older, more experienced dunlins. They are creatures of habit.
• The researchers carefully monitored the dunlin's population numbers, noting any declines related to the degradation of the salt marsh habitat, which the dunlin calls home.
• Watching the mass of dunlins take off into the sky was quite beautiful, with the collective motion and timing of their movements truly an exceptional spectacle for the viewer.
