Thermal cameras are being used to map where birds are nesting on the Somerset Levels, as part of a project to protect declining species like snipe and curlew.

The RSPB hopes the new technology will help them better understand where the nests are, and in turn keep them safe.

Traditional methods of locating curlew and snipe nests just by observation from vantage points has been very time-consuming and difficult, so conservationists hope the new technology could be the answer.
