Impact and control of feral cats preying on wandering albatrosses: Insights from a field experiment
International audience Invasive alien species are a major threat to seabird species, and the number of impacted species is still increasing. A recent study revealed for the first time that feral cats predated a large albatross species and that without cat control, some albatross populations would ma...
