Police say they believe the deaths of 16 birds of prey in the Black Isle area earlier this year were not the result of targeted poisoning.

They said they now believe the 12 red kites and four buzzards were ‘victims of pest control measures’.

Police Scotland originally said 22 raptors’ bodies had been found near Conon Bridge in Easter Ross in March and April.

A spokesperson said a criminal investigation was continuing and appealed for information and said a significant reward is still being offered.

Detective Superintendent Colin Carey said: “Investigations into the suspicious deaths of wildlife and especially raptors can be difficult and prolonged.

“The areas covered can be vast and it is seldom immediately apparent why a bird may have died.

“We work closely with partners to identify and thoroughly investigate all wildlife crime. The death of the raptors in Ross-shire remains an ongoing investigation during which we are endeavouring to establish all of the circumstances around this crime.

“We would ask anyone who may have further information to come forward.”

The spokesperson said if anyone finds any further dead birds or animals in the area they are asked to make a note of its location and inform the police on 101. Under no circumstances should anyone touch or attempt to recover any dead animal, the spokesperson added.
