Importance of urban water reservoirs for wintering Common Pochards Aythya ferina: the case of lake Minimes (Bois de Vincennes, Paris)
Importance des étangs pour l'hivernage du fuligule milouin Aythia ferina : exemple du lac des Minimes (Bois de Vincennes, Paris)
Résumé
Since several years, a small group of Common Pochard(Aythya ferina), is regularly present in winter on Minimes lake in the Bois de Vincennes in Paris. Since 2002, these birds have been monitored to estimate the size, sex-ratio and the dates of presence of the population. During winter 2006-07, this area was chosen to join the diving ducks research program of the Office National de la Chasse et de la Faune Sauvage(ONCFS). The marked birds bring news information to understand the Minimes lake's organization: fidelity to the winter area, remaining time, changes during winter and especially during cold spell, migratory patterns. With(these?) first results, we could consider Minimes lake first as a wintering area and then a stop-over place.
