Yellow HA has migrated on a more westerly track so has picked up a mobilephone mast. He roosted overnight on 17th/18th near Lac d’Guiers and on 18th flew 252 km N then NNNE inland of Nouakchott through Mauritania. On 19th March he flew 232 km NNW and then NNE; his soar and glide path was very pronounced so he was getting great lift over the deserts. At 1427GMT he started to soar from 704 metres and by 1434 topped out at 2329 metres, below gliding north – finally roosting in the desert at 1822GMT
March 18th – 19th
