On 26 November, transmissions from Chris's tag revealed that he had moved from his position in the Western Congolian Swamp forests and become the second of all our tagged Cuckoos to travel as far south as Angola! He had covered almost 800km (500 miles) and was just inside the border, in the region of Uige.
What's even more interesting than this movement south is that we have been tracking Chris for two and a half years and so know that he has spent the two previous winters in the swamp forest from which he recently moved. So what has prompted him to move? We know that rainfall has been a bit higher than usual over the past month in the area that he came from but we aren't sure whether that will have impacted conditions for him. Could food be more scarce in the area this year? If so, we may well see Derek who is in the swamp forests move on too. Keep an eye on the blog to see whether Chris decides to spend the winter in his new location or whether he returns to the swamp.
