Résumé :	The history of the population trend of this species in Burgundy can be divided in 6 time-periods: before 1940 (no known breeding record), 1950-1960 (first breeding records and spreading), 1961-1978 (decline), 1978-1984 (stagnation), 1984-2003 (a slow colonization process at the beginning and afterwards a rapid one), 2003-2008 (slowing down). Protection measures played in some ways a role in the overall trend: they consisted in raptor protection laws, nest guarding, site protection and rock climbing regulation. It is not easy to predict the future of this population: slowing down or decline? Since 2003 slowing down in breeding numbers and decreasing productivity are the rule but these values are hardly significant. The observed trend should be the consequence of habitat saturation, the best habitats being all occupied. Moreover, some pairs breed outside rocky areas and predation by Eurasian Eagle-Owl Bubo bubo has been recorded.
