Résumé :	Common Pochards ringed in winter in the Camargue and recovered during the breeding season showed that females were found in Europe from 20° E to 40°E (Poland, West Russia and Ukraine) and males from 55° E to 66° E (mostly in westernmost Siberia), both in the latitudinal range between 50° N and 60° N (would this mean that the females breeding with the recovered males winter more to the south or the southwest of the Camargue?). However, this pattern is not so clear cut because three females recovered just after the breeding season have been found far more to the east (61° - 64° E). The overall pattern shown by birds ringed in winter in the Camargue and recovered during the breeding season is in good agreement with that shown by birds ringed in Switzerland (HOFER et al., 2006 and 2010). Compared to Tufted Ducks Aythya fuligula ringed in winter in the Camargue and recovered during the breeding season, this latter species generally breeds in a more northern range (60° - 70° N) than do Common Pochards.
