An Aberdeenshire estate is appealing for help in locating a sea eagle whose satellite was last recorded in woodland near the River Dee.

Invercauld Estate, near Braemar, said the bird of prey's tag last signalled on Saturday in a native woodland and Scots pine regeneration zone on Invercauld.

Pellets are understood to have been found in the vicinity of the search, which suggest the sea eagle had been roosting there.

Efforts continued to find the bird on Wednesday with another sea eagle and two gold eagles spotted, but there have been no sightings of the absent sea eagle so far.

Estate manager at Invercauld, Angus McNicols, said: "We have spent the last two days trying to locate any trace of the missing sea eagle and we will be continuing our efforts to watch the area in case there has been a technical malfunction of the tag and the sea eagle returns to roost again.

"For several months our ranger has been working with the RSPB's sea eagle project officer to track the movements of the sea eagles in our area and if the tag is no longer transmitting then it is a concern to us.

"Invercauld hosts a vast range of bird species and other types of wildlife and we want to learn if any harm has come to the bird.

"We would ask anyone with information that could aid the search to speak to the RSPB or ourselves immediately."
