Nature Seychelles carries out seabird censuses and breeding success surveys annually. Recording changes provides insight into how each species is coping. The hardest impacted seabirds seem to be the Shearwaters; steep downwards trends have been recorded for both species. Despite all the threats facing seabirds they continue to arrive each year and each year a fresh set of fledglings takes to the sky, filling the air with their cries and acrobatics.
