| Résumé : | From 1989-1997 a stable colony of Common Terns Sterna hirundo developed on rafts at a freshwater lake in Mecklenburg-Vorpommern. Up to 28 pairs were breeding on the small rafts of lesser than five m2 (5.18 nests/m2). A mean clutch size of 2,82 eggs/first clutch and 2.30/late clutch, a hatching rate of 65.7% and a mean breeding success of 1, 15 fledglings/pair were found. With the colony growing older predation increased, causing losses of all chicks during the last breeding season. |
