WILDLIFE officers believe attempts are being made to poison a local falcon.
Special Constable Phil Sanderson, wildlife officer for Calderdale, is raising awareness about attempts to illegally poison a Peregrine Falcon in the Ryburn Valley area.
He added: “We have had a number of calls about captive birds being used in traps.
“These have all been investigated and we thank the public for their concern and vigilance but urge people not to take matters into their own hands.
“The use of captive birds is lawful and covered under a licence for the landowner and their agent to catch particular types of pests.
“There are a number of regulations covering these.
“If in doubt then let police know and we will carry out a thorough investigation and take action if any illegal activity has occurred.”
It comes as the officer raised concerns about dogs unleashed in nature reserves.
Witnesses say dogs have run into nesting areas for birds and disturbed them during nesting season.
Special Constable Sanderson said: “For good reason this is an offence under the Wildlife and Countryside Act.
“The vast majority of dog owners act responsibly but there is always the minority who spoil it for the others.’’
