B Every year from March to October, Christian Moullec, also known as “Birdman,” takes to the skies aboard his adapted light aircraft. However, the 58-year-old Frenchman’s daily 30-minute flight is not just to enjoy the impressive views, but to guide flocks ( 鸟群 ) of lesser white-fronted geese( 小白额雁 ) through safe migration paths which the birds can teach future generations. His deed began in 1995 when he noticed their declining population in the wilds of Lapland Sweden. To prevent their numbers from dropping further, Moullec tried to get the threatened species to follow him along migration routes that would protect them from bird hunters. However, getting grown geese to follow his lead proved challenging. As young geese imitate and follow whomever they view as their parent, Moullec decided to raise the geese from birth. To help raise funds and awareness of his job to protect not just the geese but birds worldwide, Moullec often allows paying tourists to join him on the 30-minute-long flights aboard his aircraft. In addition to the trained birds flying alongside them, visitors, who come from as far as a 15-hour plane flight away, are treated to a variety of crane and geese species as well as breathtaking views of castle sand cities. He often brings his camera along for the flights, capturing photos not just for their beauty, but for what they describe. Moullec believes the use of agricultural chemicals has done harm to wild. European birds, with more than a third disappearing in the last 30 years. “It's a disaster,” he said. “My beautiful images with flying birds should be used to tell this story.” 24.
