No further transmissions have been received from Kasper, who was last heard from in Algeria. We have heard from Lyster, who has remained in Algeria for a number of days after his Sahara crossing, so hopefully Kasper is doing the same and we will hear from him soon.

We have had no further transmissions from Kasper's tag since the last 8 days ago but he has now been joined by Lyster in Algeria. There is around 350km ( 225 miles) between them.

There was a brief message from Kasper over-night but without any location information. The battery charge was about one third full and it's cool and wet at the moment in the uplands of Algeria so this could explain the lack of signals.

Over the Easter period we had Kasper crossing the Grand Erg Oriental Desert but frustratingly we didn't know if he made it! However on the 9 April we found him in the north-west Atlas mountains in Algeria in the Foret de Charef. This typical Atlas habitat (see http://www.panoramio.com/photo/9456326) looks ideal staging habitat.

After 12 days with no messages from Kasper’s tag, positions received in the morning of 7 April showed he was in northern Algeria, having almost completed his desert crossing. He was moving north across the Grand Erg Occidental Desert, taking a path midway between those taken by Martin and Chris, heading more or less straight towards Algiers. Later today he should become the third of the Cuckoos to complete the northwards desert crossing.
