Article summary

Careful survey of the 265 nests of the Hensies colonies, one of Belgium's most important breeding nuclei of Great Cormorants (Phalacrocorax carbo), was undertaken in spring 2005. This study involved frequent visits to fixed observation points, and the completion of a detailed colony map. In total, 313 nesting attempts were recorded, leading to the production of 1.7 fledglings per nesting attempt. This breeding success, although slightly lower than recorded in 1999 in the same location, is still higher than the success observed in bigger colonies inside the main Great Cormorant breeding area in North-Western Europe. Among these 313 nesting attempts, 62 were apparently second attempts in re-used nests, beginning mid-May.
