In March UV was very settled in his overwintering spot in northern Senegal. He seldom travelled far from his central area to places such as the canal and Lac Guembeul to the east. Over the month he had a few trips slightly further out to sea.
This was one such trip and as you can see he flew at too high an altitude to have been foraging. Before he set off UV was perched not in water (the red dot to the right of the 13.43 fix) as the Google earth imagery was showing at that time, but on the now extended beach. Paul modelled what the area could look like following some longitude/latitude readings taken on the recent visit to Senegal.
In the last few days Google earth has added new plates which still don’t show the extent of the beach on the right. On 25 March UV travelled up the shoreline of the northern spit of the Langue de Barbarie.
On Google earth UV still looks as though he set off from a perch in the water! Their plate is dated 22 November 2016 so in three months significant amounts of sand had been deposited.
In recent days very hot temperatures – into the low 40’s – have been replaced by cooler conditions. This is why.
By yesterday the dust was spread far and wide.
Thanks to Paul for his graphics of this weather ‘event’, quite remarkable to see.
Thanks also to Vic for sharing his time lapse video of UV flying along the beach in February and thrilling his three admirers! Press the HD button and enjoy.
