UV reaches Portugal

Today’s data arrived very early with UV still at roost, but there is plenty of interesting material for this post. Here is UV’s travel yesterday.

UV flew for around 10 hours and covered 358 km. His average speed was 16 kph (including roost period). Since leaving Northern England (but excluding his stopover in the SW) he has travelled 2187 km.

Yesterday UV flew down an arm of the Embalse de la Almendra, the second largest reservoir in Spain.

Unlike his visit there in May, UV is now in full migration mode. Although he reduced height when crossing the dam, he showed no inclination to explore further. Here’s a fascinating graphic from Paul.

In May UV flew a figure of 8 across Spain and into Portugal. The bottom green track is his ‘out’ route. On 18 and 19 September UV was very close to that route in particular. From 16.43 UTC on 18 September to 10.33 on 19 September he was only a few km away from his May track and his roost was just 7.3 km from the May crossover point.

Yesterday UV started to diverge from familiar territory before he reached the Almendra but he would have recognised it given his elevation.

UV carried on flying SW over hills at first where he was often over 1000m above the terrain. He crossed into Portugal at 13.09 and by 15.19 was in an area with a number of reservoirs, including three sizeable ones, which again he ignored.

About an hour later and still over gently sloping hills the frequent fixes showed UV using the slope-soaring flying technique.

Paul wrote a series of articles in his own blog describing various flying strategies. This one
covers slope-soaring.

UV stopped for the night in a wood in lowlands nearer the coast. By tomorrow he could cross the Atlantic to Africa if he chooses a similar route to his 2014 migration. Or he may stopover in Portugal. ‘Wait and see’ time again!

Many thanks to Paul for the graphics which are more time consuming to produce than the Google Earth images.
