MINK could be to blame for Henley’s dwindling swan population, say conservationists.
The Henley Wildlife Group is to carry out a survey to find out whether the predators are living on the area’s waterways.
It wants to reintroduce water vole, an endangered species, but fears mink have set up habitats locally and will kill them.
Sally Rankin, the group’s chairwoman, said the mink might also be taking swans’ eggs. She said the group would set up three “mink rafts” on the Thames in Henley. These are small wooden floats lined with wet clay, which attract mink.
Members will check the clay for the animals’ footprints. If they find some, they will set traps.
