Hugo Ferreira is a PhD student at the University of Aveiro in collaboration with Tour du Valat Research Institute. His project aims at assessing the processes influencing population dynamics of a migratory bird species throughout the annual cycle, and in doing so, gather a comprehensive overview of the mechanisms beyond the inter-individual variation in migration tendencies. His model species is the Eurasian Spoonbill (Platalea leucorodia) and the study will be focusing in the dynamics of the spoonbill colony in Camargue (South of France).
