Curlew, a Near Threatened species, are a major feature of The Wash where they occur in nationally important numbers. They are declining throughout their range and, in the UK: the 25-year (to winter 2019–20) population trend for Curlew is -33% and the 10 year -18%. We see them feeding on both the tidal mudflats and on the inland fields, where they eat earthworms.

Curlew are declining so alarmingly that they are now ‘Red-Listed’ as birds of conservation concern. The Wash is one of the two main UK sites for both passage and wintering Eurasian Curlew (the other being Morecambe Bay – WeBS data).

Some birds will move on to smaller sites around the Norfolk coast, the southwest of England, and northwest France. Here they will spend the winter before returning to their breeding grounds. The majority of Curlew using the Wash breed in Finland and Sweden, a migratory journey of over 1,000 miles. There is more background information on our Curlew page.

The crew came out with us early on a beautiful sunny Saturday morning when our target was Sanderling, one of our 11 study species, which we were able to catch.
