Julien was born in France in 1964 and he lives near Paris. He is an amateur ornithologist and he has been interested in birds since 1996. He enjoys tape-recording bird voices with his Telinga, especially birds’ calls, and afterwards looking at the sonagrams. He possesses quite a large collection of calls and songs of his region’s birds. However, since 2006, Julien has also been catching images of birds, in digiscoping mode. He is an active member of a local nature conservation association, NaturEssonne, whose aim is to study birds and to protect interesting biotopes in the south of Ile- de France, near Paris.
