RSPCA Cymru is appealing for information after 12 dead doves and pigeons were found in Flint.
A member of the public contacted the RSPCA on 24 September after finding the dead birds on a flat roof in the Church Road area.
RSPCA inspector Tim Jones said: “We are not sure what has happened, but we believe they were poisoned and are now trying to find out where any poison could have come from. There were around three doves and the rest were pigeons.
“We have no way of telling whether this was a result of a deliberate act or because of poisonous substances not being safely stowed away, but what is concerning is the number of birds that were found dead. We don’t want this happening again.
“Anyone with information about this incident to call the RSPCA on 0300 123 8018 in confidence.”
It is an offence to injure or kill a wild bird under the Wildlife and Countryside Act 1981 except under licence and offenders can face a fine of up to £5,000 and/or six months imprisonment.
