Abstract
Abstract The Greater Flamingo (Phoenicopterus roseus) is listed in the appendices of se-veral international conservation agree¬ments including the Barcelona Conven¬tion. We combined 30 years of data from the International Waterbird Censuses (IWC) across North Africa, coordinated by the Mediterranean Waterbirds Network (MWN), with over 30 years of monitoring by the “The Network for the study and conservation of the Greater Flamingos in the Mediterranean and West Africa” to assess trends of the species in the Mediterranean basin. Wintering bird count data were analysed using a new statistical approach called LORI, while breeding data were sum¬marized through descriptive analyses. The number of breeding pairs in the Camargue, as well as across the broa¬der Mediterranean region, has generally increased over the past few decades. A similar trend has been observed for wintering flamingos in North Africa. In the last five years, both breeding and wintering populations appear to sta¬bilize despite important fluctuations from year to year. Strengthening the link between breeding and wintering moni¬toring networks could provide critical insights into emerging trends and un¬derlying causes of these changes.
