A prolonged period of strong wind meant that we were pretty late in the season to catch our last bird. The number of potential sites in Broadland was drying up and at least 2 of the birds previously tagged had moved more than 10km from where they were tagged so we were worried the birds might have finished breeding. A recce in Thetford Forest soon located a singing bird which reacted strongly to a tape and on 1 June we set nets around a low bush. The resident male was there immediately but kept high in the trees. After making us wait for an hour and a half, a young male came in and the resulting chase ended with the young male in the net. We had captured our final bird. Hear the excitement of how we caught Chris in the BBC Radio 4 series Saving Species.

Chris is third Cuckoo to complete crossing - 14 Apr 2014

Chris remained in the east of Ivory Coast until at least 6 April.  In the late afternoon of the 11 April, a series of transmissions revealed he was on the move and was in Mauritania, flying over the El Djouf Desert at the western edge of the Sahara, having already covered 1525km (950 miles) from his previous location.

Just north of the El Djouf Desert, he then changed course to head north-east, arriving in northern Morocco in the early hours of the 14 April, shortly after Waller also arrived in Morrocco having completed his crossing. This makes Chris the third of our Cuckoos to cross the desert successfully and is the third return desert crossing over which we have eagerly followed his progress. This year, he seems to have ended up much further west than after any previous crossings. He was tagged in the first year of the project and is the only remaining bird from the original five tagged. Over the three years, he has helped us to learn amazing new things about Cuckoo Migration and we hope that he continues to do so! 

Chris in Ivory Coast - 24 Mar 2014

Chris is the most recent Cuckoo to have joined the five others in Ivory Coast! Having been in Ghana until at least the 18 March, he then flew 215km (130 miles) which took him over the border and into Ivory Coast by the 21 March. He is now only 75km (45 miles) from Skinner's location and 70km ( 42 miles) from Ken's location. 

Chris is in Ghana - 17 Mar 2014

By the early hours of 14 March, Chris had left Central African Republic and signals showed he was in the south of Nigeria. The next signals received on 16 March revealed he had contined on and was in Ghana. He had travelled a total of 1900km (1180 miles) from his location within Central African Republic to Ghana in no more than five days at most! In previous years he has arrived in Ghana between the 13-17 March, so once again he is on schedule!  

Chris heads to edge of rainforest - 25 Feb 2014

On the afternoon of the 20 February, Chris's tag sent tranmissions from southern Congo but, by early morning on 25 February, he had travelled 930km (580 miles) to reach a location in the  south-west of the Central African Republic. He has now flown right over the block of Congo rainforest, and is very close to it's northern edge. Its the first time we have seen him do this, largely because in previous winters he hasn't travelled so far south, instead choosing the swamp forests of eastern Congo.  He is just 80km (50 miles) south of David, the most northerly tagged Cuckoo, who moved to the edge of the forest at the very end of January. 

It's amazing that we are still gathering data for Chris having first tagged him in spring 2011. We now have three southward autumn migrations and two northward spring migrations for him.  Having taken up a different wintering location this year, it will be really interesting to see whether this changes his return strategy. We are keeping our fingers crossed for his safe return once again to the UK.  

Chris starts his northward migration - 22 Jan 2014

On the 17 Janaury a series of poor quality locations indicated Chris had left his previous position and was heading NNE. A signal on the 20 January revealed he had crossed the border into Congo and had traveled 550km (345 miles) almost due N to a location in the region of Pool, about 80km ( 50 miles) north-west of the capital of Brazzaville.

This is likely to be the first stage of his northward migration. Having wintered so far south this year in Angola, it will be interesting to see if he continues to the north of the Congo Rainforest, as we have seen our British Cuckoos do each winter or whether he will remain to its south for a while, like the Scandinavian birds have after wintering in Angola.
