Curlews: curlews have a long, downcurved bill which enables them to extract prey from the estuary mud. They eat lugworm and ragworm, as well as crabs, shellfish and other prey. They can be seen in fields feeding on earthworms. Their diet can also consist of invertebrates, such as beetle larvae.
Avocets: the avocet can often be seen moving its bill from side to side through shallow water as it feeds. Its diet consists of worms, crustaceans and invertebrates, like midge larvae.
Lapwings: the lapwing, which has a smaller bill, feeds on invertebrates like leatherjackets and beetles. It takes them from the ground or close to the surface of the water.
Turnstones: turnstones feed on mussels, periwinkles, crabs and barnacles, as well as insects.
During the summer our skies fill with the dark silhouettes of migrant birds. It is the invertebrate-heavy diet of these species, as well as the colder temperature, which means they migrate and do not spend their winter in the UK.
