The data on UV today was only until lunchtime, but by then he was nearly as far south in Senegal as he has been to date.
Yesterday he spent the afternoon in the Langue de Barbarie area, travelling north mainly up the eastern side of the long peninsula. Just after sunset UV was roosting inland in the wetlands created when the peninsula was breached as flood prevention for St Louis to the north. But that wasn’t his final roost; he flew about 35 km south in decreasing light, arriving at an overnight roost at about 20.00 GMT.
Today he was on the move at daybreak flying over the sea but stayed in the vicinity of his roost until after 11.00 when he headed…. south.
He flew past Rutland Water 30(05)’s area late morning, again avoiding it.
He carried on down the coast often at speed which was helped by a variable tail wind – N at 12-14 knots (that is 22-26 kph) – and at altitudes of up to around 500m ASL at times.
By the last fix at just after 13.00 he was about 60 km north of his most southerly overnight roost near Lake Retba on 25 January.
The comparison of the ‘ups and downs’ of UV’s recent travel is difficult to illustrate, but Paul has made a valiant effort which is as clear as can be achieved. Thanks to him for this graphic. Click to enlarge it and see the helpful arrows.
Juvenile ospreys tend to meander about to establish a territory but actually until now UV has not exhibited this. He arrived in SW Portugal and stayed in one small area albeit with some day trips. At the Gulf of Cintra he remained near at the north end with one excursion for a few days to the south of the bay. Now he is back and forth. One could speculate that possibly he is in good habitat a few weeks too early. 30(o5) will not be the only experienced osprey along the stretch of coast. Although there is no evidence that he has been ‘chased off’ from anywhere. Maybe he is looking for something more like a Portuguese reservoir and he won’t find that!
The prevailing winds need to change direction before the breeding ospreys will leave for Europe and those same winds will constrain UV’s options. Whatever he does next it won’t be flying back to Portugal.
