A SECOND satellite-tagged hen harrier has gone missing just weeks after the transmitter of another bird stopped responding.

North Yorkshire Police is appealing for information after the young female bird, released in the Yorkshire Dales in July as part of a brood management scheme, has disappeared off radars.

It is known from satellite tag data that the bird had the bird stayed in the Hawes area since her release, with one excursion to the Sedbergh area on September 16, then south to the West Pennine Moors near Horwich September 17 to 19 before returning to land near Semerwater where she had remained for at least a fortnight.

The last transmission from the bird’s satellite tag was received on the 29 September on Thornton Rust moor, 3.37km east of Semerwater but since then no further transmissions have been received from the tag.

A spokesperson from North Yorkshire Police said: "Natural England field staff have carried out checks with a hand-held scanner and monitored the area with no findings and North Yorkshire Police have also searched the area with colleagues from the Yorkshire Dales National Park Ranger team, as well as making extensive local enquiries.

"The bird is a juvenile female, brown in colour and ringed with the BTO ring number FJ48404.

"This appeal for information sadly follows the disappearance of another satellite-tagged hen harrier in the area, this one a juvenile male known as 183704 who was last known to be in the area of Askrigg Common on 19 September.

"At this time North Yorkshire Police are keen to locate both birds safe and well, but if found deceased the birds can be subject to post mortem to establish if the cause of death was from natural causes or if criminal activity was involved.

"If you find the bird or have any information please contact North Yorkshire Police on 101 and quote reference number 12190186540."
