Just a few miles from Dunfanaghy a wildlife haven called the New Lake is the permanent homes to scores of swans.
It's normally a safe haven, however, now investigations are underway to determine how a number of the swans have died.
In recent days 33 swans have been recovered from the waters of the lake. It's thought they may have died over a four week period.
The dead animals have been collected by the Republic's National Parks and Wildlife Service and samples have been sent to veterinary laboratories for testing.
A number of sick swans have also been rescued by the park service.
