The drama unfolds on the shore often over food. Sanderlings feed on little invertebrates, worms and shrimps at low tide. The Black-headed gulls have worked out it is easier to steal a meal rather than catch their own.

A Sanderling weight is 50 -60 grams and a Black-headed gull’s weight is 200-400g so the gull is the bully but the Sanderling is extremely fast so they do not give up their meal that often.
