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.  

A period of recovery - 12 Sep 2014

With most cuckoos now in the Sahel region, we're entering a fairly quiet period in the annual cycle of the tagged cuckoos with less movement than during the migration season.

Birds who completed their desert crossing will spend time in the Sahel recovering their body condition, and some may stay quite a long time. In previous years, cuckoos have stayed in this area for as much as several months, while others spend a shorter amount of time before moving south into the humid zone forests.

The eastern Sahel in Chad and south Sudan has received plenty of rain recently, and thus conditions are likely good for cuckoos. Northern Cameroon was slightly drier than average in August, and so cuckoos such as Derek, Dudley, Stanley, and Emsworthy may be moving on if foraging conditions aren't suitable.

Derek heads east - 1 Sep 2014

Since the 27 August Derek left Burkina Faso and headed east. By the 29 August he was in Nigeria and by 31 he was in Cameroon, close to its border with Chad. He has covered over 1800km (1120 miles) in this time and is now one of the more southerly Cuckoos.
