Record-breaking Cuckoo returns to Suffolk

One of the BTO’s satellite-tagged Common Cuckoos Cuculus canorus has returned to his Breckland breeding territory for his fifth successive summer. ‘PJ’ was fitted with his tag in June 2016 in King’s Forest, Suffolk, and has been providing researchers at the BTO with valuable data ever since. His arrival back in Suffolk sees him complete his fifth annual migration cycle to, from and within Africa since being tagged, having travelled well over 50,000 miles in the process. He’s the only satellite-tagged Cuckoo to have achieved such a feat since the project began in 2011.
