Camera-trap footage has revealed that the world's smallest and rarest pigs are "thriving" following their release into the wild last year.
Conservationists say this film and other surveys suggest that the captive-bred pygmy hogs have adapted well to their new home in the grasslands of Assam in India.
The team now plans to reintroduce more of the little pigs to this habitat.
Pygmy hogs stand just 25cm-tall (10in) and weigh only 6-9kg (13-20 lbs). Few are thought to exist in the wild.
