Census of Little Owls Athene noctua in Île-de-France (Paris region). Updated data. To improve our knowledge of the badly known distribution of the Little Owl in Ile-de-France, the CORIF started a regional standardized census in 2010. This census was based on the cartographic modelling of the species' distribution. The study highlighted the major importance of grassland areas, buildings and intensive agriculture in shaping the occurrence of this species. The most favourable areas were the north-west of the Yvelines, the west and east of the Val-d'Oise, the extreme north-west and north-east of the Seine-et-Marne regions. At the saure time, the study showed one pair over five years or more. In 2015 some that 89% of the favourable sites were used by 490-750 pairs were estimated to occur
