In this episode, we chat to Simba Chan from the Japan Bird Research Association about the incredible story of the critically endangered Chinese Crested Tern. These seabirds live and breed between the seas between China and Japan, part of what's known as the East Asian-Australasian Flyway, a highway for sea birds and shorebirds that extends from Australia to the Arctic. Conservationists who work in the flyway have dubbed 2022 the Years of the Terns, putting the spotlight on these threatened birds.

And in northern Australia we speak to Dr Mariana Campbell from Charles Darwin University about the recovery of Estuarine Crocodiles, Australia's biggest reptiles. Hunted close to extinction in the 1970s, their numbers have rebounded. Mariana's research is looking at what's behind the recovery.
