VY explores the Casamance area

VY has stayed along the northern side of the Casamance River since her arrival in the area on 19 September. The last post described her change from ‘full on’ migration into an apparent search for a winter home. In the late afternoon of 19 September she had a couple of stops as she explored the wetlands and generally she was flying at fairly low elevations. Her roost area is typical of the habitat.

The southern most fix by the watercourse was at 18.18 UTC but by that time fixes are too far apart to tell if she had tried to catch supper. The latter part of the night was in the western trees.

On 20 September she moved away around 07.00  and for about 90 minutes was stationary by a larger stream. She moved a few km early in the day during her more active migration so although foraging is a possibility it can’t be confirmed.

The next image shows her overall travel during 20 September.

She had a short day of activity with several stops. Whilst consistent with her behaviour on 19 September the weather may well have had an influence – Paul’s graphic follows.

She perched by the Atlantic Ocean for nearly 30 minutes before cutting inland rather the following the coast. Quite a few fixes are visible near Blue XD’s territory.

Until the last 4 minutes VY was approaching the area too high to be hunting so unless she scooped up a catch in her talons as she came down to land a fish was not involved! When she flew away she gained altitude for a short time before continuing at under 100m above the terrain for the rest of the day, which effectively ended soon after 13.30 when she reached the area she roosted in. She was still at the roost (yellow fix) this morning when an early data download arrived. The two fixes SSE of her initial stopping point were around 16.00 for about 30 minutes; yet again there are too few fixes to determine whether she was trying to fish. The salty water channels are known as bolongs.

Paul has made an animation of the last couple of days showing the frequent stops and slower speed of her travel – our thanks to him. VY has now covered 6010 km since leaving Kielder.
