When we last heard from Coo on 3 May, everything seemed OK with him. He had arrived back on his breeding grounds and was moving around quite widely. The information from his tag was also indicating that everything was fine but then everything stopped and we have received nothing since. Of course we don't really know what happened but with the failure being so catastrophic and sudden we have to consider that Coo has been predated.

A host of signals received from Coo's tag aroung breakfast time on 1 May showed that he was back at RAF Fylingdales, completing a round journey of almost 15,000km (9,500 miles). Since his arrival he has been flying all over the RAF Fylingdales area, presumably in search of female Cuckoos.

A signal received from Coo's tag early this morning showed that he had travelled a further 260 miles from his last location in France. He has now crossed the channel and is near Battle in East Sussex. The next map update should show us whether he is hanging around in East Sussex or pushing straight on back to the North York Moors.

On the 19 April Coo was still in Spain but by the early morning of 24 April a location received from his tag showed that he had crossed the Pyrenees and was in France, 520km (323 miles) north of his last position in Spain.He is currently in Centre region in an area of woodland just west of Marigny-Marmande.

Since the last update we have received better quality locations from Coo's tag which show that he is now in norther Spain, just south of the Pyrenees and within 10 miles of Vigilamus.
