Press release from RSPB Scotland:
Hen harrier numbers have fallen by 9% in Scotland since 2010, according to the latest national survey of these birds, with the total population now estimated to be less than 500 breeding pairs.
The fifth national hen harrier survey was carried out in 2016 by the RSPB, Scottish Natural Heritage (SNH) and the Scottish Raptor Study Group, along with a range of other UK partners, and covered the whole of the United Kingdom and the Isle of Man.
In Scotland the results revealed a drop in breeding pairs to only 460, compared with 505 pairs from the previous survey in 2010. The UK population is now estimated at 545 breeding pairs.
This is the second successive decline in the Scottish hen harrier population revealed by national surveys, signalling a worrying trend. In the longer term, over the last 12 years, the number of breeding pairs has dropped by 27% in Scotland.
Known for their majestic skydancing ritual, hen harriers are one of the most threatened birds of prey in the country. Independent research has identified illegal killing as one of the main constraints on this species, along with a changing climate and the loss of heather moorland and other suitable nesting habitat to commercial afforestation and overgrazing.

Scotland is still a major stronghold for hen harriers, with 80% of the UK population. However, having a breeding population of fewer than 1000 birds makes this species vulnerable to the effects of habitat degradation and, in some areas, wildlife crime. The west Highlands continue to provide a home for the majority of Scotland’s breeding harriers (estimated 175 breeding pairs), while Orkney and the Hebrides were the only areas of the country to show a slight increase in the number of these birds.
According to the survey, similar hen harrier declines have been witnessed in all other parts of the UK as well. In England, these birds are on the brink of extinction as a breeding species, with the population falling from 12 pairs in 2010 to only four pairs last year. Meanwhile, Wales saw the number of pairs fall by more than a third over the past six years, from 57 to 35, and Northern Ireland recorded only 46 pairs in 2016 compared with 59 in 2010.

Duncan Orr-Ewing, Head of Species and Land Management at RSPB Scotland, said: “The hen harrier is an indicator of the health of our upland environment, and the fact that its population continues to decline is of major concern. The hen harrier is a high priority for our conservation work and urgent steps need to be taken to tackle illegal killing of this species and to improve their moorland breeding habitats.”
Eileen Stuart, SNH’s Head of Policy & Advice, said: “While Scotland remains the stronghold for hen harriers in the UK, the continuing decline is a serious concern particularly the low numbers found in parts of the mainland. We’re committed to continuing to work with a wide range of partners to tackle wildlife crime through PAW Scotland, including initiatives such as Heads up for Harriers, and General Licence restrictions where evidence supports such action. Scottish Natural Heritage and Forestry Commission Scotland have set up a joint Raptor Working Group to identify and promote the opportunities of forestry for raptors, including hen harriers, to sustainably deliver Scottish Government environmental and forestry policy.”
Wendy Mattingley, from the Scottish Raptor Study Group, said: “There is a very concerning trend of a long term decline in the number of breeding hen harriers in Scotland. For the population to begin to recover and expand over all suitable habitat, the intensively managed grouse moors of east and south Scotland must produce successful breeding hen harriers again. The hen harrier is a wonderful spectacular raptor and more action must be taken to ensure that its future is secure.”
Tim Baynes, Director of the Scottish Moorland Group, said: “Scotland is still the UK stronghold for the hen harriers by a huge margin. However, it is disappointing to see any indication of decline in Scotland – and much larger drops in Wales and Northern Ireland – even though the decline is regarded by the survey team as statistically insignificant. Harrier breeding fluctuates annually for many reasons – not all associated with wildlife crime. For example, 2016 was a poor year largely due to low vole numbers in Scotland with weather and predation shown to have played their part. Fifteen of our members, covering an area of 325,000 acres, will be working with the Heads Up for Harriers project again this year to better to understand the reasons for poor harrier breeding and to help rebuild the harrier population.”
Simon Wotton, lead author of the study, said: “This survey required a monumental effort from a number of different funders, organisations and volunteers – without their help, dedication and expertise we wouldn’t be able to build up this accurate picture of these magnificent birds of prey. We hope these results will convince everyone in a position to help hen harriers to take positive steps to ensure their protection and rebuild the country’s population for people to enjoy for generations to come.”

If there’s anybody still wondering why approximately 2,000 pairs of hen harriers are ‘missing’ in the UK uplands, here’s a short yet instructive video which explains everything:
And let’s not forget, just two weeks ago Tim (Kim) Baynes of Scottish Land & Estates claimed that illegal persecution of hen harriers was an “historical controversy” and that “a better idea of current numbers [of hen harriers] will emerge when the results of the 2016 UK harrier population survey are published, but the overall picture is expected to be broadly the same in Scotland“ (here).
We’re thinking of changing his name to Duplicitous Tim.


As regular blog readers will be aware, the Crown Office & Procurator Fiscal Service (COPFS), the public prosecutors in Scotland, have, in the space of two months, either dropped or refused to prosecute five cases of alleged wildlife crime. These include:

Public prosecutors from Scotland’s Crown Office have dropped yet another case of alleged wildlife crime.
As a brief interlude from what’s going on in Scotland, we thought we’d turn our attention back to England and the Government’s bonkers Hen Harrier brood meddling scheme….
