The pair are both ‘colour ringed’. You can see the rings on their legs when they stand up in the nest. Tony Cross the project ornithologist ringed these birds and many other curlew at their pre-breeding roost on the River Severn as part of the project work. Please report other colour ring sightings to Tony or the BTO: https://app.bto.org/euring/lang/pages/rings.jsp?country=EN as soon as possible, to help update the much needed research on curlew movement and activity.
Curlew spend the winter in coastal areas and can be found around the UK’s estuaries and mudflats.
