Every year from March to October， Christian Moullec， also known as "Birdman，" flies to the sky aboard his 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（迁徙） paths which the birds can teach future generations．
His deed began in 1995 when he noticed their declining population in the wild． To prevent their numbers from dropping， Moullec tried to get the geese to follow him during migration that would protect them from bird hunters．
However， getting adult geese to follow his lead is challenging． As young geese learn 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 of protecting not just the geese but other birds worldwide as well， 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， can enjoy a variety of crane and geese species as well as breathtaking views of castles and cities．
He often brings his camera along for the flights， taking photos not just for the breathtaking scenery， but for what they convey（传达）． 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 pictures with flying birds should be used to tell this story． "
