Glen was in his usual night roosting area in the hills on nights of 15th/16th and 19th/20th and a signal after dawn on 20th suggests that he was heading downhill to hunt on farmland and rough grazings around the edge of the heather moors.
On 8th March, there was a one line signal from Glen’s transmitter – impossible to deduce anything from it except the transmitter is not destroyed. There is just a possibility that as the sun rises higher and gets stronger the battery may get charged enough to show if the transmitter is on the ground or Glen is still alive.
Still no signals from Glen’s transmitter – unable to say if it’s due to the lack of sunlight in December (he has the small solar panel transmitter) or that something has happened to him
The dark days of November can be a problem as very little sun hits the solar array on the transmitter as so we receive no transmissions.
Two very accurate locations came in today and this morning Glen was a couple kms west of his previous position. He was close to the coast near Lagg on the southern coast of the Isle of Arran.
Transmissions coming in this morning, included a highest quality one (less than 150 metres) at 11am. He is still on the Isle of Arran, at the south end at Bennan, just east of Lagg. He was, presumably hunting, in farmland, along a small rough grassland valley, between the moors and conifer plantations and the coast.
Very surprisingly, the five locations on 30th October gave Glen’s position in the southern part of the Isle of Arran, 250 kms back to the NW. We had had such a good response from the Irish hen harrier watchers but now he’s left their study areas.
This morning, 6.06am a class 2 signal showed that Glen was 464 kms SW of Glen Lethnot, Angus (his location on last signal 20th October); four other transmissions gave the same general area. It’s very exciting to check the data and suddenly find that one of the birds has made a big move. He is in an area of low intensive farming, bogs and plantations near Kilglass Lough, Co Roscommon, between the villages of Carrigeen and Barravalley. Brian Etheridge showed with the large scale wing-tagging of hen harrier chicks, that 5% of sightings outside Scotland came from Ireland, mainly young from the north and west Highlands. He believed that the percentage would be much higher than 5% because of the scarcity of observers, during the study, to see and report sightings of wing-tagged harriers.
Glen remains in the same area of hills 15 kms NW of Brechin, overlooking the coastal agricultural plain. Accurate class 3 and 3 locations (dark and light blue dots) in a side glen of Glen Lethnot came in for 9th October.
This evening Glen was again in a side glen of Glen Lethnot. He seems very settled in this general location on the edge of the Angus moors.
