Today: The travelling cuckoo

May 5th, 2015

Episode 334 of 1744 episodes

Over the past four years Chris the cuckoo has visited twenty eight different countries, crossed the Sahara Desert eight times and reached speeds of up to 60mph. He’s just returned again to Suffolk after his annual migratory trip to Southern Africa. He was fitted with a satellite tag in May 2011 which means scientists now have four years’ worth of very detailed information which they describe as "unparalleled" and a "massive contribution to science". Cuckoos are in huge decline, with almost three quarters wiped out since the late 80s. Chris Hewson is the lead scientist on the project at the British Trust for Ornithology.
