Invasive mammals, such as cats, rats and mongooses are known threats to seabirds throughout the Caribbean and beyond. Detecting them on remote, offshore, and difficult to access islands is challenging, yet it’s crucial information for conserving these imperiled birds. EPIC and Ocean Spirits Inc. joined efforts to survey seven islands in the Grenadines using trail cameras and baited tracking tunnels to determine if invasive mammals, particularly rodents, were present. These tools allowed researchers to monitor the islands without being there all the time. They also recorded information on other introduced mammals such as rats, cats, and opossum, which can directly injure or kill seabirds by eating eggs or chicks, while livestock can trample nests and cause disturbance and erosion. So far, the team has recorded rats, goats, and even chickens at these remote sites. This information helps us to prioritize conservation actions needed to protect these regionally and globally important seabird nesting areas.
