| Résumé : |
Strong pressure exists on wetlands as a consequence of urbanisation, agriculture, fish farming, industry, hunting, recreation, forestry or military activities. As a result, the birds breeding sites are regularly destroyed or abandoned. However, new colonies can potentially emerge to compensate lost ones. As such, we can identify four critical aspects essential for new colonies formation: 1) Natal or breeding dispersal (De le Court & Aguilera 1997, El Hamoui et al. this volume); 2) suitable new sites that provide protection from disturbance and feeding grounds (Marion, this issue); 3) colony growth and 4) stabilization. Here we focused on the Eurasian Spoonbill Platalea leucorodia Camargue colony located in Southern France that is growing exponentially (Blanchon et al. this volume) to document the process of colonization. Specifically, we quantified early-life demographic parameters and compared them with those from older new born colony from Italy.
