In the stunning wildlife series Lost Land Of The Volcano, an international team of scientists, cavers and wildlife filmmakers, including Steve Backshall, Gordon Buchanan and Dr George McGavin, venture deep into the heart of the remote tropical island of New Guinea.
Combining remarkable wildlife discoveries, such as the 82cm, 1.5kg Bosavi woolly rat, with high octane adventure they explore the giant extinct volcano, Mount Bosavi.
Here, the amazing finds include the world's smallest parrot and some unusual frogs.
The team push deeper into New Guinea's rainforest, and enlist a tribe to help them find the birds of paradise as they perform their courtship displays.
