Dunlin

Calidris alpina

NT · Near Threatened

Identification

A compact wader with a slightly downcurved bill. Breeding birds show a dark belly patch; winter birds are much plainer grey above and white below.

When to look

Romanian wetlands offer passage and non-breeding observation opportunities. Plumage and flock composition change as different age groups move through.

Where to look

Mudflats, shallow lagoons and coastal margins provide non-breeding feeding areas. Its breeding habitats lie much farther north.

Behaviour and ecology

Food and nutrition

It searches soft wet substrates for small invertebrates, using its bill to pick and probe. Exposed feeding edges can change quickly with water levels.

Breeding and life cycle

Nesting occurs on northern tundra, wet grassland and related habitats, depending on population. A coastal flock in Romania should not be labelled a local breeding colony.

A closer look

Seasonal plumage can make summer and winter Dunlins look very different. Comparing structure with nearby waders helps bridge that change.

Global conservation assessment

NT · Near Threatened

Global category recorded from the linked assessment; it does not describe local abundance. Least Concern does not mean absence of threats.

Observation and photography

Scan mixed flocks for bill shape, leg length and body proportions. Leave both feeding areas and high-water resting places undisturbed.

Sources and further reading

Keep a distance that allows birds to feed and rest normally. Do not enter colonies, approach nests, flush roosts or use playback for photographs. Never publish precise nest locations of sensitive species. Follow reserve rules and your guide's advice.
