Ash, Emsworthy and Derek move to forest edge - 4 Feb 2015

It looks like a few of our Cuckoos are setting off on their first spring migration movements. Ash and Emsworthy have both joined Stanley in making a move northwards to the Congo rainforest edge while Derek has been in the area for a few days but only transmitting low quality signals, until now, which hadn't registered on the maps. 

Sherwood Cuckoos move west - 21 Jan 2015

Fred and Jake, two of our Cuckoos tagged in Sherwood Forest, have moved westwards and are now in Congo. Fred recently left the Mbandaka area and has moved about 270km (165 miles) west from his previous location in Democratic Republic of Congo, while Jake, who is about 70km (45 miles) further south, travelled a shorter distance of 155km (95 miles). 

Interestingly, Derek who is slightly further north, had been moving east, the opposite direction to Jake and Fred, until recently but he has backtracked around 65km (40 miles). Emsworthy has also moved, but northwards to the area not long vacated by Fred. These movements may indicate changing conditions which are encouraging the Cuckoos to seek more favourable areas. 

Emsworthy and Derek move west - 18 Dec 2014

Derek and Emsworthy have recently moved westwards and are now south-west of  the Site Lac Tele-Likouala Aux Herbes area. Chris had also been in the area before moving south to Angola, possibly due to dryer conditions in that area this year. 

Derek in swamp forests - 2 Oct 2014

Derek has moved south to Congo and is now deep in the swamp forests where fellow East Anglian Cuckoo Chris has previously spent some of the winter months. 

Derek moves east - 22 Sep 2014

Derek has moved 175km (110 miles) east and is now in the Central African Republic. As suggested in a previous blog this may be down to it being slightly drier than average in Northern Cameroon as Dudley and Emsworthy have also left that area.
