In 1969, a Peruvian farmer called Gustavo Del Solar received an unusual assignment - finding a bird called the white-winged guan that had been regarded as extinct for a century.
After years of searching, he found the bird deep in Peru’s wilderness in 1977. He then made it his life’s mission to save the species, setting up a zoo in his family home.
Thanks to Gustavo's discovery, the Peruvian government protected the white-winged guan and its population continued to grow. His son, Rafael Del Solar, tells Ben Henderson about his dad's love for the 'chicken-sized' birds.
