Sussex is the most southerly Cuckoo03 Sep 2013
By the 31 August, Sussex had left Chad and headed south, revealing his new position in the Central African Republic. The excitement at Whortle and Patch's movements over the weekend meant this new movement was slightly overshadowed but he has actually travelled 450km (280 miles) and is now further south than Nick, making him the most southerly of all our tagged Cuckoos! Only David is also in the Central African Republic, in the very north tip, about 550km (340 miles) away from Sussex's location.
