More than 150 species of birds around the world are considered "lost" with no confirmed sightings in the past decade, conservationists say. A bird last seen more than 170 years ago in the rainforests of Borneo has been rediscovered, amazing conservationists who have long assumed it was extinct. The Black-browed Babbler has only ever been documented once — when it was first described by scientists around 1848 — eluding all subsequent efforts to find it. But late last year, two men in Indonesian Borneo saw a bird they didn't recognise and snapped photos of it before releasing the palm-sized creature back into the forest, according to Global Wildlife Conservation.
