Hen harriers – an inconvenient truth

Hen harriers – an inconvenient truth

19 Jun 2020

Natural England recently gave the green light
for the controversial hen harrier brood management scheme to go ahead
for a second year. However, has the government been sufficiently open
about events last year near the very first brood management site in a
notorious part of North Yorkshire?

We can reveal that two hen harrier nesting attempts failed in
suspicious circumstances near the brood management site in 2019. To
date, this fact has not been publicly mentioned by Defra or Natural
England (NE), not even in their own brood management report. Why is
Let’s rewind a bit.
In January 2016 Defra launched its Hen Harrier Action Plan,
which included the controversial brood management scheme, to be carried
out by Natural England (NE). This involves removing hen harrier eggs or
chicks from driven grouse moors when pairs nest within 10km of each
other on a grouse moor. The birds are then reared in captivity before
being released into upland habitat. The RSPB does not support brood
management: we believe that illegal persecution must be tackled first
and foremost. The RSPB and Dr Mark Avery are both currently in appeal
proceedings against brood management.
The brood management trial, due to run for five years, started in 2019 on the Swinton Estate in North Yorkshire.
Five chicks were removed from a nest, fitted with satellite tags, and
released elsewhere later that season. Along with another pair on the
estate, this was the first successful breeding of hen harriers in North
Yorkshire since 2007. This area of North Yorkshire, dominated by driven
grouse estates, has an appalling history of raptor persecution and
repeated hen harrier breeding failures due to suspected human
However, in August 2019, Defra and NE announced triumphantly  ‘A Record Breaking Year for Hen Harrier breeding’
with 15 nests producing 47 chicks. In fact, only 12 nests were
successful. In relation to the three unsuccessful nests it stated: ‘The three nests which failed were all in Northumberland – two were lost to bad weather and the third was predated’.
Twelve successful nests is a far cry from the 300 breeding pairs England could support. 
More nest failures
However, the government media release announcing the 2019 breeding
results filed to mention another two failed nesting attempts on grouse
estates in North Yorkshire, within just five kilometres of the brood
managed pair. We don’t know who may have been responsible for these
failures. NE knew all about these, and had spoken with North Yorkshire
Police, so why miss out this part of the story?
One of these failed nests was on the edge of an estate. As well as
on-the-ground monitoring information, we also received disturbing
information from a very reliable source which may – we don’t know for
sure – explain why this nest failed. Our source told us that a
gamekeeper from another nearby estate had shot the male bird and the
nest site had later failed. Whilst this is only an allegation, it did
fit with the events on the ground, which were unknown to the person who
contacted us. This information was passed to the police and the National
Wildlife Crime Unit.

Seeking information
The RSPB made requests under Freedom of Information (FOI) and
Environmental Information Regulations (EIR) to Defra, Natural England,
North Yorkshire Police and the National Wildlife Crime Unit. We asked
for details of any communication exchanges since the start of November
2018 –

  • in relation to hen harrier brood management in North Yorkshire plus
    any suspected, potential or confirmed persecution incidents involving
    hen harriers.
  • with sporting estates in North Yorkshire in relation to hen harrier
    brood management or any suspected, potential or confirmed persecution
    incidents involving hen harriers.

The date (November 2018) coincided with the RSPB filming of a masked man with a firearm in a hen harrier roost on the Swinton Estate in North Yorkshire, and the last satellite transmission from hen harrier ‘River’ from the same estate. River’s body was later discovered on another part of the estate the following spring. She had been shot.
Amongst the material supplied by NE was confirmation they had
received from the police the information, originally from the RSPB,
about the allegation that a gamekeeper had shot the male of one of the
failed nesting pairs.
However, we were surprised to see that there was no Defra or NE
correspondence, either internal or with other government agencies or
sporting estates, concerning the two nesting attempts which had failed
in highly suspicious circumstances.
As part of the brood management scheme there is a requirement ‘To produce an annual report to be assessed by Natural England ornithologists, to assess the progress of the trial’.
We decided to wait to see what was in this report. We understand this
was completed earlier this year so why it has not been published online
is unknown. However, we were recently sent a copy of this report
obtained via an EIR request by a Raptor Worker. The report introduction
states: ‘In 2019 an estate in North Yorkshire had two Hen Harrier
nests on it within 10km of each other. Under the trial parameters this
qualified them to undertake brood management. This report deals with the
experience gained and lessons learnt form undertaking the brood
management intervention on one of these two nests
The report mainly focusses on the technical aspects of brood
management. You would have hoped the suspicious failure of two nesting
attempts so close to the brood management location fell under ‘experience gained & lessons learned’.
Even if NE claim this is outside the remit of the report, then we are
still left asking the question: were NE ever going to publicly mention
these failed nesting attempts? I suspect not.

A lack of openness
This inconvenient truth is not in their joint August 2019 media
release. It doesn’t feature in any of their correspondence supplied to
us, or the 2019 brood management report. It was not even raised at the
last two Raptor Persecution Priority Delivery Group meetings post August
It would seem important for Defra and NE to ensure absolute
transparency about events that are taking place given the exposure the
brood management scheme has received. This does not appear to have
On 22 May this year NE announced that brood management licences were being renewed for 2020. Days later it emerged that all five brood-managed chicks from 2019 are now ‘missing’.
The fact that there has been no update from Defra or NE this year about
these birds, and what information is available had to be requested,
displays a lack of openness. Whether persecution is behind the
disappearance of some, or even all, of these birds, is unknown, though
the decision to use a different, and possibly less reliable, type of
satellite tag has further clouded the picture.
Hopefully, going forward we will all be given real transparency about
the BM process and on the threats still being faced by our hen
