- The young bird, named Reiver, was satellite tagged as a chick earlier this year, allowing scientists to follow her movements after leaving the nest
- Reiver’s tag had been functioning as normal until 17 September – it has not transmitted since
- The tag showed the bird’s last known location was an area dominated by driven grouse moors in Northumberland
- Reiver is the third Scottish satellite-tagged harrier to disappear in England in suspicious circumstances in 2021
Another satellite tagged hen harrier has suddenly and unexpectedly disappeared, strengthening the RSPB’s call for the urgent licensing of grouse moors.
Reiver, a young female, fledged from a nest on Langholm Moor in the south of Scotland this summer. She was fitted with a satellite tag while still in her nest, as part of an RSPB project to help understand the journeys made by these red-listed birds of prey and the survival challenges they face after fledging.
Reiver’s tag was transmitting regularly and as expected, with no sign of malfunction, until it stopped suddenly on 17 September 2021. Her tag’s last fix came from Ninebanks, an area dominated by driven grouse moors in Northumberland, within the North Pennines Area of Outstanding Natural Beauty (AONB).
Reiver is the third Scottish satellite-tagged hen harrier to vanish in identical, sudden and suspicious circumstances in England in 2021. In February this year, Tarras disappeared having been last recorded in an area dominated by grouse moors near Haltwhistle, just outside the North Pennines AONB boundary. Another bird, Yarrow, from the Scottish Borders disappeared in April while heading for the North York Moors. And in 2019, Ada’s last transmission came from an area of grouse moor east of Allendale, Northumberland.
Fewer than 600 pairs of hen harriers breed in the UK. In England there were just 24 successful nests in 2021, despite enough habitat and food to support over 300 pairs. In 2019, the government’s own study found illegal killing to be the main factor limiting the recovery of the UK hen harrier population.
Jenny Barlow, Estate Manager at Langholm said: “There is always such anticipation and excitement for our hen harriers to return each year to the Tarras Valley Nature Reserve here in Langholm. A huge community and volunteer effort goes into monitoring and safeguarding our harrier chicks to make sure they get the best possible start on our reserve. It is extremely sad news for us all that one of our chicks Reiver, won't be making her way back home to us again.”
Howard Jones, RSPB Investigations Officer, said: “It is almost certain that Reiver has been illegally killed. This is more than just a pattern, it is a known fact that hen harrier numbers are so low because of persistent persecution. Satellite tags are highly reliable and will continue to transmit even after the bird’s death. For a tag which has been functioning reliably to suddenly cut out like this strongly suggests foul play. This event is categorised as a ‘sudden stop no malfunction’ and is happening time and again on or near driven grouse moors.
“Hen harriers disappearing on English grouse moors is having a devastating effect on both the English and Scottish hen harrier populations, and needs to be urgently addressed by UK governments. The need for licensing of grouse moors has been accepted in Scotland and this needs to be recognised in England too. This then must be implemented without delay in both countries.”
All birds of prey are protected by the Wildlife and Countryside Act 1981. To intentionally kill or injure one is a criminal offence and could result in an unlimited fine or up to six months in jail.
