It is a job that requires both carefulness and patience, as volunteers and experts put on rings on birds' legs and examined them at the end of August.
They were working for the Sandwich Bay Bird Observatory (SBBOT).
The SBBOT is an accredited bird observatory, monitoring and recording species at the Sandwich Bay reserve, including birds, mammals and insects, notably moths.
