Hen Harrier disappears in Northumberland
Northumbria Police and the RSPB have issued an appeal for information following the sudden disappearance of yet another satellite tagged Hen Harrier – a female known as Ada.
Ada hatched on a nest on the Scottish Borders this summer. She was fitted with a lightweight satellite tag as part of the RSPB’s Hen Harrier LIFE project, to learn more about the journeys made by these rare birds of prey and the survival challenges they face.
Ada was only a few months old when she disappeared in an area of grouse moor in Northumberland (RSPB).
Ada was the first of the chicks tagged this summer to leave her nest and proved to be naturally adventurous. After fledging she flew north, spending some time on a disused golf course near Dunbar, then she headed south to the North Pennines.
On the morning of 10 October 2019 she sent her last transmission from an area of grouse moor east of Allendale, Northumberland. Her tag showed no signs of malfunction and there were several satellites passing over, so it was expected to continue to provide data. RSPB staff were in the area at the time the tag would have transmitted, but neither the bird nor her tag could be found nor have been heard from since.
Her disappearance is being treated as suspicious and was reported to the police. Evidence shows that Hen Harriers continue to be killed, or disappear in suspicious circumstances, particularly on or near land managed for driven grouse shooting.
Scientific research published in March 2019 showed that 72% of the satellite tagged Hen Harriers in their study were killed or very likely to have been killed on British grouse moors, and that Hen Harriers were 10 times more likely to die or disappear over areas of grouse moor relative to other land uses.
Dr Cathleen Thomas, Senior Project Manager for the Hen Harrier LIFE project, said: “Over 30 chicks were tagged this summer and we’ve watched with interest as they’ve grown up and flown around the country. We’re absolutely gutted that Ada has disappeared in suspicious circumstances at just a few months’ old.”
Emma Marsh, Director for RSPB England, added: “Hen harriers have become a rare breeding bird across the UK mainly due to illegal persecution by humans. Our own tagging work has shown that survival of young birds post-fledging is very low.
“This won’t change until something is done about illegal persecution. The Government’s own data has highlighted a loss of 72% of their tagged birds in suspicious circumstances, and we are calling on them to take vital measures to address this appalling situation.”
If you have any information relating to this incident, call Northumbria police on 101.
