The latest transmissions from Ken's tag show that he remains in Gabon, having arrived here on 25 October, and it's likely he will spend Christmas here.
This is also the last country from which we received a transmission from Scottish Cuckoo, Chance, in early December. We haven't heard from him since but, there could be a number of reasons for this, including the fact that the dense cover of vegetation could be stopping the solar-powered tag from receiving enough light to charge up and transmit a signal.
Interestingly, Tor, one of our Devon Cuckoos also last transmitted from this area at the end of November, although from slightly further south within Congo, and his tag has also yet to beam another signal to us. Many of our Cuckoos have had periods where they have 'dissapeared' for a period of time before reappearing, often having moved quite substantial distances as part of their migration, having spent time feeding up beforehand. We will have to wait and see whether further transmissions reveal more information.
