We've previously reported that Senan's tag battery has been low for a while and not charging properly. After a long period of silence, we were pleased to receive the locations from Algeria, and later from Spain, to show he was migrating. However, with no further signals since the 5 May, it looks like we may finally have lost contact with him. Similarly, Tennyson's battery has also experienced charging issues and we had hoped we would receive signals at some point during his northward movements, when the solar panel was exposed to longer periods of sunshine. However, we've not heard from his tag since early April. In both these cases it appears we have lost the tag signal rather than the bird and we hope both these Cuckoos return to the UK safely - even if it's unlikely we'll be able to update you. Do keep your eyes peeled if you are on the Norfolk/Suffolk border though!

Northwards movements from Tennyson
At the end of March, Tennyson moved north-west within Liberia. A further update on 6 April showed he had continued north 290km (180 miles) along the border of Liberia and Ivory Coast. His current location remains just inside Liberia. Tennyson has been in Liberia since mid-March and this northward movement could be a sign he is getting ready to leave, though PJ was the first to move into West Africa.
