Last year we brought you a story about the swift parrot – one of Australia’s most charismatic birds, but also one of its most endangered. Each year every swift parrot in the nation flies south to Tasmania to breed. Logging and land-clearing have decimated their habitat but conservation biologist Dejan Stojanovic also made the startling discovery of why the parrot numbers were plummeting so rapidly – a very unlikely predator – the deceptively sweet sugar glider was eating them. In a race against time, Dejan and his team raised thousands of dollars through social media to save the parrot. Mark Horstman returns to Bruny Island in Tasmania to witness their remarkable recovery.
