As previously reported, the young male Osprey named Perky (PY2) migrated as far as Switzerland before halting his journey at the Lac de Joux, writes Diane Bennett, Tweed Valley Osprey Project Officer.

His tracking data revealed daily visits along the north shore of the lake, with occasional crossings to the far shore and a roost site north of the lake, near to a chalet beside a forested track.

We received news from Wendy Strahm, the osprey coordinator responsible for the reintroduction of ospreys in Switzerland, that all of the captive bred Swiss ospreys had left the area and had migrated and so she was surprised that Perky was still in the area and generously offered to go and have a look for him. She had great success and this is the report of her visit along with the photographs of a healthy looking Perky flying above the Lake.

Wendy wrote: “Perky (PY2) let me discover a bit of forest in Switzerland (that was quite clearly Osprey heaven) that I had never been to before.

"The expedition started at 8am on September 15 when Stephen Rytz, Loïc Oswald and myself set off for the Vallée de Joux, armed with the latest GPS readings (sent to us by Tony Lightley and Diane Bennett) of where Perky had spent the night, and where he had been fishing during the past few days. When we arrived we were greeted by cool temperatures (4°) and cloud, with a thick layer of mist covering the lake and lower forested slopes. Far from ideal conditions to see any bird, much less a Scottish Osprey that was making a break in his migration in our Swiss lake.

"I thought that I knew the Vallée pretty well, but I had never walked in the beautiful forest where apparently he had spent the last two nights.

"However, GPS is amazing and from Google Earth we were pretty sure that we had found the actual tree where Perky had roosted – a nice dead pine on a slope near a forest clearing. Thank you Forestry Service for leaving dead trees!

"We then retired to the Hotel de la Truite (appropriately named after Osprey food) for a coffee, as it was hopeless looking for anything. There we were joined by Olivier Jean-Petit-Matile, an excellent naturalist and photographer who knows the Vallée de Joux better than almost anyone.

"After we finished our coffee at 10am, the fog was beginning to lift so we returned to the lake shore where PY2 had been recorded a lot, and were suddenly greeted by brilliant sunshine and clear views over the lake. We took a few real postcard photos, but still no Osprey…

"Suddenly, at 10.55, we spotted Perky flying towards us. He then dived twice into the shallow water by the edge of the lake but both times his fishing trip was unsuccessful. So, we had seen PY2 and were delighted, even though he had been too far away to take a decent photo. He then disappeared around a bend and out of sight.

"We walked a little closer to where he had been fishing, hoping that he would return. And we were lucky, since at 11.45, he again flew into sight, and then perched in a tree. Again too far away for a decent photo, but we got one through the telescope.

"Suddenly at 12.10, he soared up high over our heads and Olivier managed to take a great photo – you can even see his blue ring on the left leg.

"He then proceeded to fly to the southern end of the lake, where we saw him hovering over the little nature reserve located here, but it was a long way away. We jumped in the car to get to the end of the lake, but by the time we got there he had gone, so we don’t know if he had managed to catch a fish or not. We hope that Perky heads off soon as it is definitely getting colder”.

Since Wendy and her friends spotted Perky, he then took a tour the next day, all the way down to Geneva where he was reported on the Swiss birding site as being spotted spiralling high above the town with two buzzards. He didn’t stay long and doubled back to the Lac de Joux and he is still in the region and doesn’t seem to be in any hurry to move on south just yet.

His sister, Pinky (PY1), is still in Spain and, like Perky, she has ventured further south only to double back north to the Rio Agueda where she is making the most of this rich habitat for good fishing.

You can now follow all of the tracked Scottish ospreys from 2017 on the Movetech website which is updated every 30 minutes to show their movements in progress as they migrate. The Tweed Valley birds are numbers 631 (Perky) and 632 (Pinky). Follow this link http://movetech-telemetry.com/
