UV received a few brief mentions in early November – he was mainly loafing in his wintering grounds in coastal northern Senegal. Since then, he has had a couple of trips inland to a canal he visits occasionally. He turned round and flew back to the coast after, at most, a few minutes there. On one journey he was flying at over 1000m ASL for several fixes, and over 400m ASL for much of his excursion. Some high flying offshore has been a feature of his recent days.
The cluster of fixes near the 13.45 dot is over an area UV has favoured of late. The water will be shallow there – you can see sandbars on the Google Earth image above – so fish should be easily spotted. But UV has also been making repeated trips to just past a shelf in the Atlantic Ocean.
Where the shallow water meets deeper ocean the ample food sources at such current margins are likely to support plenty of fish. UV may be watching birds, or even marine creatures, foraging there. But, for the most part, he seems to catch his own meals nearer shore.
UV may have changed his preferred foraging area over the last couple of days. A ‘health warning’ first. There are few fixes until about noon at the moment. The weather has been partly cloudy and UV’s relative inactivity also reduces the frequency of ‘pings’ to satellites. He could have exhibited similar behaviour to that shown in the above images during the mornings. But he has concentrated on the river in the afternoons.
The satellite imagery on Apple maps is slightly more recent than the April 2017 Google Earth pane.
UV had been foraging just below the northern part of the Langue de Barbarie (left on the image) until 23 November. Yesterday, as on 23 November, he was attracted to the area arrowed. This photograph shows the view of the river from the edge of the trees on the island of Doune Baba Dieye.
UV would have been over the river at the left hand edge of the photo.
Unless there is news meriting a post, there will be one or two updates a month over the winter.
