Résumé :
|
In 2001, after strong evidence rising from sightings made a few years before, the breeding of Purple Heron Ardea purpurea was confirmed on the marsh known as Vy-le- Ferroux in the Haute-Saône (70) (Franche-Cornté region, eastern France). These records constitute the first recorded breeding case of this heron in the area since the 19th century, at least. Although older breeding cases cannot be completely excluded, the few data collected on the breeding biology seem to validate the hypothesis of a recent recolonisation. The species bred successfully in 2002 and 2005 at least. In the context of the species critical decline, this breeding provides the Vy-le-Ferroux marsh with a great interest.
