The dunlin is one of the most common and widespread wading birds found in the UK during winter. These small, active birds are often seen in large flocks along the mudflats of the Thames Estuary, including near Southend Pier. In their winter plumage, dunlins have plain grey backs and white undersides, while in the breeding season, they sport reddish-brown feathers and a striking black belly patch. 

Dunlins feed on small invertebrates like worms and crustaceans, which they pick from the mud using their slender, slightly downcurved bills. Their quick movements and synchronized flock behavior make them fascinating to watch as they dart and weave along the shoreline. 

Despite being numerous, dunlins face challenges from habitat loss and climate change, making estuaries like the Thames vital for their survival. Look for their characteristic foraging behavior during low tide for the best chance to spot them.
