Fears that a red kite could have been illegally killed in the North Pennines have been raised by wildlife experts.

The young bird had been fitted with a satellite tag at Rowlands Gill in June 2019 and had since been monitored by the RSPB.

The bird, nicknamed ‘KK’, toured northern England, making it as far as the Peak District, then returned north and has been faithful to the Derwent Valley region ever since.

KK’s tag had been functioning normally until it suddenly and unexpectedly stopped transmitting. The last fix came from an area of driven grouse moor near the Derwent Reservoir on April 17. It has not been heard from since.

The North Pennines AONB Partnership, Durham Police, the RSPB, and Friends of Red Kites have launched an appeal for information following the bird's disappearance.

Emma Marsh, RSPB England director, said: “If you’ve seen a red kite wheeling high overhead you’ll know that they’re splendid birds. They enrich our landscapes and bring joy to many.

“When a tag which has been functioning reliably suddenly cuts out, this gives us immediate cause for suspicion. The additional fact that the tag’s last data fix came from an area dominated by driven grouse shooting rings serious alarm bells."

Red kites are specially protected under the Wildlife and Countryside Act (1981) which makes it an offence to deliberately kill or injure this species. Those found to have done so could be given an unlimited fine and/or a prison sentence.

Harold Dobson, spokesman for the Friends of the Red Kites, said: “It’s 15 years since the first red kites were re-introduced in the Lower Derwent Valley. They are faring well in the valley itself and we enjoy watching these impressive, majestic birds of prey.

“As mainly scavengers, the red kites are of no threat to anyone. However, we fear that human persecution is preventing them from naturally expanding their range, since 2010, seven red kites have been found poisoned or shot near the Derwent Gorge and surrounding Durham Moorland. We fear that this may be the tip of the iceberg and that many more persecuted kites are never found.”

Inspector Ed Turner, the lead for wildlife and rural crime for Durham Constabulary said: “The fate of this red kite is not yet clear, we are working with the RSPB to establish what has happened since its transmitter unexpectedly stopped on April 17, 2020. Until we can rule out the possibility that a crime has not been committed, then we will be taking this matter very seriously and if anyone has any information please contact the police quoting 22042020-0078.”

Chris Woodley-Stewart, director of the North Pennines AONB Partnership, added: “Though the fate of this bird isn’t certain, the fact that it was carrying two reliable trackers means this looks very like a crime may have been committed. This is an area where a significant number of kites have been shot or poisoned and we’d really appeal to anyone who knows anything that might help shed light on this incident to come forward.”
