Two Cuckoos to spend Christmas in Gabon? - 23 Dec 2013


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.  

Two Devon Cuckoos still being tracked - 12 Nov 2013

We are still following two of the four Cuckoos tagged in Dartmoor earlier this spring. Tor is in Congo, west of the Téké Plateau and Whortle is in the closed canopy forest in DRC, between Lac Mai and Lac Mumba and is midway between Patch and Waller.

The other two Cuckoos tagged there both perished in August, Ryder struggled to cross the desert once he arrived in Africa, while Dart made it to Mallorca but wa likely affecfed by dry conditions and wildfires there.

Tor in Crystal mountains? - 24 Oct 2013

We hadn't received transmissions from Tor's tag since 10 October when he moved to south Gabon and we were starting to get worried. Early this morning, however, we received some poor quality signals which reveal that he may have moved west and may now be in the Crystal Mountain area of south-western Congo. We will have to wait for better signals to confirm whether this is a real movement but we are relieved to have some received some news. 

Tor moves closer to wintering destination - 10 Oct 2013

By the 28 September, Tor had left the Kano region and was in the Yobe region of Nigeria, 350km (200 miles) to the east. The next (poor quality) signal we received from his tag was 975km (600 miles) further south in Cameroon on 7 October. By the early hours of this morning he had completed a further 700km (430 miles) and was in Gabon, close to the south-eastern border with Congo.  This new position puts him as far south as David.

Tor moving west - 29 Aug 2013

Since the 24 August Tor has been gradually moving westwards. Signals received early this morning show he is now 410km (255 miles) further west than he was 5 days ago. He is now 50km (32 miles) from the city of Kano, the capital of the Kano region, which has the second largest population in Nigeria after Lagos.
