Birds of prey breeding success

Mar Lodge Estate recorded 32 hen harrier chicks this year, making it the site’s most productive year to date after the species colonised the area in 2016. Since then, the number of breeding pairs has grown year on year reaching a high of 11 pairs in 2023, with eight of these breeding successfully to produce the bumper number of chicks.

In addition to the positive news of the hen harriers, it was also a fruitful second year for the pair of white-tailed eagles that set up home at Mar Lodge last year. After producing one chick, Mar’verick in 2022, this year they changed the location of their nesting site on the estate and produced two chicks that have now fledged successfully.

Shaila Rao, Conservation Manager at Mar Lodge Estate, said: ‘We’re thrilled at the news that the birds of prey which choose to call Mar Lodge home have had such a great breeding year. This amazingly productive season is likely to be a result of a vole population peak that is providing an abundant food supply for hen harriers and other birds of prey which live on the estate.

‘We have worked in partnership with the RSPB to satellite-tag four female chicks to allow us to learn more about hen harrier ecology and it will be great to see where these birds head off to once they have fledged. We were delighted to hear that two female harriers that were tagged on the estate last year as chicks, bred successfully for the first time elsewhere in Scotland.

‘With the bountiful food supply on offer, it’s no coincidence that this year we had many more sightings than normal of the ethereal short-eared owl, and we were lucky enough to be able to confirm this breeding success after finding some short-eared owl chicks nestled in the heather.
