UV: Roaming in the gloaming and other times too!

UV has been quite active in the first part of February, shifting his roost point after dark and in the day travelling up to 30 km south of his home territory. As in late January sometimes he has flown for up to three hours or a little more without landing. This image shows his journey south to near a fishing village, Yodi, on 3 February. He made a similar flight on 15 February.

However UV’s focus between 5 and 9 February was north, with quite a few hours perched on the northern part of the Langue de Barbarie or an island east of it. On 8 February he made a late start from his roost area, then spent some time at the outflow from Lake Guembeul before going to the aforementioned areas.

Eagle-eyed readers may note that in the top left of this image the start of the southern part of the Langue de Barbarie seems truncated in a neat line! This is because the Google Earth image pane for the area to the north is dated 30 December 2015 but the pane to the south is still from 19 April 2015. In that time another part of the southern Langue de Barbarie has been eroded – how much we will be able to tell when Google Earth update again. The new pane enables us to be clearer about the reason for UV’s occasional visits to an area near the Ngalam river. It looked fairly arid on the April 2015 view, but since then a canal has been built and the area is now lush. UV visited there on 10 February, a day when there was no data showing him near the Senegal River or Atlantic Ocean.

Since 10 February UV has concentrated on southern coastal areas again and has mostly perched towards the southern end of the Langue de Barbarie. Or further south. On 12 February he was away from his roost before 08.00 and didn’t return until after 19.00, but it wasn’t one of his busy exploring days!

Before the 2003 breach was cut in the centre of the Langue de Barbarie the Senegal River used to flow into the sea where UV was perched at the extreme left of the image.

Earlier we mentioned the new Google Earth pane dated 30 December 2015. As well as showing the new canal from the Ngalam River it has provided evidence of some of the “barrier” planting that is part of the effort to reduce the impact of coastal erosion. You can see the uniform lines in this close up image of the island (and former village) named Doune Baba Dieye.

UV sometimes spends a few hours on the southern part of the island – as shown in the 8 February image.

The village on the island was destroyed in 2011 by the power of the ocean. In the images in the slideshow the unforeseen (by most) consequences of creating the breach to relieve the threat of flooding to Saint Louis are evident.
