UV goes sightseeing

How long have you got? The last week has been pretty busy for UV so here are selected highlights!

19 and 21 February were his ‘quiet’ days on his home patch  with much roosting and just a couple of trips to sea. This was him on 21 February with well over 8 hours of roosting. Although he did have quite a long flight to the coast and north past the village of Fas Boue in late afternoon.

In between those two days he was more active. Despite a headwind he travelled past Fas Boue, generally at under 20 kph, until he was only a few km from Rutland Osprey Project’s adult female 30(05)‘s wintering grounds. And we know she is still there from her tracker.

If you click on the image and zoom in you can see in the centre he spent some time exploring near two pieces of water. These are sedimentation ponds, part of a surface mineral sand extraction concession licensed to TiZiR. The double line of UV’s path to the right of the ponds is him flying parallel to the dredging operation.

22 February was another day with little of note although UV did fly quite high – over 200m altitude – when over the sea. He was not hunting because  he could not have seen fish so presumably he was scouting around the area. And that was a hint of things to come!

On 23 February he headed north in light winds past Fas Boue again, at times just under 700m high. This time he kept going but gave 30(05)’s area the respect a mature adult deserves, heading inland some way!

UV spent the afternoon in the area just north of 30(05) and further inland. He roosted in that area overnight, his first night any distance from his ‘home’ territory since he arrived there at the start of the month.

On 24 February UV spent the morning in the same general area but then flew north again. Here is a graphic from Paul which gives a very good idea of how high he flew as he used the thermals to soar.

He travelled about 40 km reaching the lagoon at the southern end of the Langue de Barbarie which he had visited in January as he flew south.

He headed back south in the late afternoon and roosted overnight in the same area as the previous night. He spent 25 February around, but mainly in, the Lompoul Desert, an 18 km² desert.

The circled area is an area of Berber style tents and a small Lodge offering accommodation. UV stayed clear of that but all his day roosts were in the desert area. It is probably a fanciful human reaction to wonder if he is missing the lagoon at Cintra and roosting in the Sahara.

On 26 February he went not north back to the lagoon at the Langu

e de Barbarie but south to his usual area. Again he flew very high, over 800m, as he headed south. And he gave 30 a wide berth! This second graphic from Paul, to whom many thanks for both, shows his behaviour on the ‘out’ and ‘in’ journeys and his relative altitude.

Today’s e-mail has just arrived and so far (just after 16.00 GMT) he has had a very quiet day. So tomorrow may not be!

You can follow 30(05) and many other ospreys in Europe and the US as they migrate north via WOW, a great initiative by the Rutland Osprey Project.
