Scientists have recorded one of the longest bird journeys.
Using satellites, scientists at the Mongolia Cuckoo Project tracked the journey of an ordinary cuckoo called “Onon”, which has been around since 20 October 2015. From 12,500 kilometers from Zambia in southern Africa to Mongolia, it flew about 12,500 kilometers from Zambia in southern Africa to the end of May. In doing so, Onon flew as many as 16 countries and survived a crossing over the Indian Ocean that passed without stopping.
Onon is one of five cuckoos whose journey scientists have followed, but in one and only that they could confirm that it had indeed reached its goal. its counterpart cuckoo Bayan was not so lucky. It went near Mt. Kilimanjaro and made it all the way to the north of China where it died either of exhaustion or ended up preying on another bird.
