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.

Coo is on his way back! Locations recieved during the evening of 16 April showed him close to a large lake, Hassi el Morra Tahtania, in the northeastern Algerian desert. However, since then we have received three poor quality locations that show he didn't stay here long. The poor locations place him close to Los Menas in southern Spain. We will have to wait for good quality locations to confirm this but it does look like he has crossed the desert and the Mediterranean.

A location received during the morning of the 31 March showed that Coo had flown 401km (249 miles) west and was in Ivory Coast. Another location received from him during the evening of 2 April showed that he was still close to the area he arrived in a few days earlier and was just south of the town of Boussikouamikro-Bongue and in an area of quite wet forest. It might not be too long before he attempts his desert crossing.

Since arriving in Ghana on 5 March Coo seems fairly settled, presumably resting and feeding up for the next leg of his journey home. We last heard from him during the early morning of 24 March, showing that he had moved 52km (32 miles) east and back towards Lake Volta. He is currently close to a large tributary on the northwest edge of the lake.

Coo has moved another 403km (250 miles) west. A series of locations received from him in the evening on 5 March show that he is in Ghana, 78km (48 miles) northwest of Lake Volta.

After going missing for fourteen days, Coo has popped up again. We received a good quality location from him mid-afternoon on 27 Febraury that showed he was in Benin, and on his way back! Coo is the first of our tagged Cuckoos to make the move into West Africa. He is currently 27Km (17 miles) from the border with Nigeria, and 5.5km (3.5 miles) southeast of Gobe.

We last heard from Coo on 13 Feb, showing that he had moved 161km (100 miles) northwest and crossed into Congo. The information received at the time showed that the charge on the tag's battery was low. This is something that we have noticed from other Cuckoos at this time of the year. We think that they move deeper into cover in search of food as they prepare for the next leg of their journey. Hopefully Coo will 'pop-up' again in the next week or two, as he leaves deeper cover, and be on his way back to the UK.

Coo has moved north and is now 400km (250 miles) north-west of his mid-winter location in the DRC. He is currently just north of Lac Tumba and will be preparing for his next move north and west and the beginning of his long journey back to the UK.

A location received from Coo during the early morning of 16 December showed him settled on the southern edge of the rainfrest, in the area that he has spent the early part of the winter.

Coo was on the move again over the weekend, and by Sunday evening was 120km south west of his location on Friday evening. He is now much closer to the southern edge of the rainforest and only Larry (in Angola) is further south. It will be interesting to see if he heads any further south during the next week or so.

Coo is settled in the area of the Congo rainforest in DRC that he arrived in on 13 September. We last heard from him at 19.23 on the evening of the 3rd November. It is likely that he will stay in this area for the next couple of months.

Since the 10 September Coo has moved 810km (500 miles) further south, flying over Central African Republic.  By 13 September he had made it to northern Democratic Republic of Congo and areas of lowland forest. He is the first of our tagged Cuckoos to make it to the Congo Rainforest this year. 

Since the early hours of the 7 August, Coo has continued on his desert crossing, covering a further 800km (500 miles) to reach the semi-arid Sahel region of central Chad. Here there will be opportunities to rest and feed up in the grassland and savanna, with occasional areas of woodland and shrubland. He is the sixth Cuckoo to successfully complete the desert crossing. 

Coo has been very quiet for sometime and we did wonder where he was but his tag sent a reliable signal yesterday helping us pinpoint him in the Libyan desert approaching the border between Libya and Chad.

Newly named Cuckoo Coo is on his way and is currently in the Po Valley, Northern Italy, 50km (30 miles) southwest of Milan and 1,240km (772 miles) from his tagging location on the North York Moors.
