Résumé :	Searching for the Eagle Owl in non-rocky areas has shown the occurrence of breeding birds which were far to be expected in such areas. Three nesting sites are described : 1) ground nest at the foot of a tree in a formerly grazed grassland, 2) ground nest on a small rocky outcrop in an open oak woodland close to cultivations and to a road, 3) open wooded lowland near an inhabited farm. This area is further occupied by other ground nesting pairs using woodlands or small rocky outcrops. The population is probably in a phase of recolonization of deserted habitats following persecutions in former time. Owing to their ecological plasticity, cryptic plumage and nocturnal life, Eagle Owls are able to find suitable nesting sites and accessible food resources in areas where they are not expected. Bird observers are invited to search for this species in such unexplored areas. The monitoring of these birds should allow a better understanding of their more or less regular reproduction, their dispersal and finally their survival rate.
