UV’s Spring 2018 migration route
UK sites of significance to Kielder
Kielder Ospreys in Autumn/Winter 2017/18
Two juveniles were fitted with GSM/GPS transmitters. Blue 7L/Aln from Nest 2 migrated using a ‘staging post’ strategy, with some short and one long staging posts. She is overwintering on the Mauritanian coast.
In contrast, Blue 9L/Archer from Nest 4 took a direct route which included some long days of travel. She appeared to have settled in a wetland area near Ross Bethio in NW Senegal when transmissions ceased.
Another view of the route.
Blue UV successfully completed Spring and Autumn migrations, both with staging posts. The map allows easy comparison of his routes over the years.

Detailed information about VY’s migration is on the blog; search under ‘abroad’. ‘migration’ and ‘Blue VY’ for all relevant posts.
VY left Kielder on 3o August and made steady progress through Europe.
After crossing to Africa VY travelled considerably further than the 2014 tracked Kielder juveniles, reaching the far south of Senegal in late September.
After a few days exploring the Casamance River, the winter home for some other UK tracked ospreys, VY went south to Guinea Bissau for a few days before returning to the Casamance.
2014/5: summary autumn migration maps for tracked juveniles
Detailed information about the migrations is in regular posts on the blog main page.
The map below shows Nest 2 female 7H’s migration from 7 September until mid October when she was on stopover in Morocco. She remains in the same area.
The map below shows Nest 1 male UV’s migration path from 2 September to mid October. He had been at stopover in SW Portugal since 15 September.
The next map shows his onward journey to the Western Sahara, where he remained until 21 January 2015.
From 21-25 January UV flew south, mainly very near the coast, as far as just north of Dakar in Senegal. He then started re-tracing his route. The map below shows his journey from Cintra to his location in northern Senegal until late April.
This map shows UV’s location from late April to date and his previous Senegalese site.
The map below shows the migration route of Nest 1 female VV from 31 August to 11 September when data uploads ceased. She was on the edge of the Atlas Mountains and probably perished trying to cross them or in the Sahara beyond.
