A pioneering trial set up to help rebuild the population of the endangered Hen Harrier in England has reared and released 13 chicks this year.

Hen Harrier numbers have shown continuous improvement over the past six years, coinciding with the introduction of the government-led Hen Harrier recovery plan in 2016 and the availability of the Brood Management trial two years later. The trial has seen 34 chicks from 9 broods take to the wing in total. Five of the brood managed birds have gone on to breed in the wild, adding 17 chicks to the wild Hen Harrier population.

Video footage shows the innovative brood management scheme in action at estates in Yorkshire and Cumbria which have been participating in the trial.

The aims of the brood management trial are to understand if it is possible to rear hen harriers in captivity and then release them to become successful breeding adults in the English uplands and also to investigate the effects of this technique on the perceptions and behaviour of the moorland community. It is one of a suite of actions set out in the Hen Harrier Joint Action Plan, which also includes direct work to tackle persecution.

The trial involves eggs and chicks from wild nests being reared for a few weeks at a specialist bird of prey centre before being transported to pens on grouse moors where they are tagged and monitored before being released into the wild, back into the same general areas that they came from. The trial is conducted under strict licence conditions overseen by Natural England, a Project Board and Scientific Advisory Group.

Jemima Parry-Jones, chief executive of the International Bird of Prey Centre, Gloucester, said: “When I first heard of the brood management scheme, I was sceptical about if and how it would work but I am so happy to see that, year after year, it has delivered, taught us a great deal and given hen harrier chicks the best possible start to their lives.”

Amanda Anderson, Director of the Moorland Association, said: “Everyone involved in the trial has worked hard over the last five years. We have seen some incredibly encouraging results and this will give scientists plenty of evidence as they consider what next steps should be taken. All credit to estates and gamekeepers for stepping up and participating in the trial as part of their commitment to help rebuilding the harrier population.”
