Dog owners from across Mansfield and Ashfield are being warned to keep their pets on leads after a swan was killed at King’s Mill Reservoir.
It is the third time a bird has been killed at the nature reserve this year.
An adult swan was killed by a dog off a lead earlier in the year and a further two birds, a gosling and a duck, have been killed by dogs this month.
There are signs around the area asking people to keep their dogs on leads while they are near the boatyard to ensure the safety of the wildlife - but some owners are apparently ignoring the signs.
Coun Warren Nuttall, portfolio holder for Environment, public health and community protection, said: “Ashfield District Council is reiterating the message by placing stakes around the area and asking members of the public to contact them if they witness dogs off a lead in this area.
“Community Protection Officers (CPOs) also routinely patrol the area.”
We have previously reported other incidents in Ashfield where wildlife has been harmed by loose dogs.
Last year, a swan was viciously attacked by a Staffordshire Bull Terrier and a rottweiler. The swan, which also had contracted lead poisoning after swallowing a fishing line, weight and hook, later died
