Satellite-tagging Hen Harriers

"We know that a number of these birds have vanished, and we know from the tags exactly where they've vanished - we know what the land use is on the ground where they've vanished - and what we're basically doing here is putting pieces in the jigsaw and at the end of this project we'll be able to look at it in its entirety and produce a scientiific paper that shows exactly what has happened to our tagged harriers..." Mark Thomas, May 2018 Hen Harriers, a protected species of bird of prey,routinely disappear in 'suspicious circumstances' around grouse moors – a pattern that’s becoming increasingly evident and impossible to dispute now that large numbers of Hen Harriers are being satelllite-tagged, which means their movements can be accurately tracked. Charlie Moores talks with Mark Thomas, an RSPB Investigations Officer and Dr Cathleen Thomas, the RSPB's Hen Harrier Life Project Manager, about 'disappearing' Hen Harriers and the work the RSPB does to help the public understand more about these magnificent but hugely persecuted birds.
