| Résumé : | The underparts colouration of 318 breeding Barn Owls was investigated. In the 9, the distribution among 5 colouration types is non spectacular and has its predominant peak at the type "guttata" In the male, not only the lighter types ("alba") are more frequent but there is a second peak in the very light type. The authors speculate that this could reflect immigration from the west. English text see www.kniprath-barnowl.de |
