Introduced and native vertebrates in pink-footed shearwater (Ardenna creatopus) breeding colonies in Chile
Biodiversity conservation planning requires accurate, current information about species status and threats. Although introduced mammals are the greatest threat to seabirds globally, data on introduced species is lacking for many seabird breeding islands. To inform conservation planning, we used trai...

Biodiversity conservation planning requires accurate, current information about species status and threats. Although introduced mammals are the greatest threat to seabirds globally, data on introduced species is lacking for many seabird breeding islands. To inform conservation planning, we used trail cameras to document the presence, relative abundance, and seasonal and diel attendance of introduced and native vertebrates within pink-footed shearwater ( Ardenna creatopus ) breeding colonies on Isla Mocha (five colonies, 2015–2020) and Isla Robinson Crusoe (Juan Fernández Archipelago), Chile (one colony, 2019–2020). The most commonly detected species were pink-footed shearwaters and introduced rats ( Rattus spp.) on Isla Mocha, and European rabbits ( Oryctolagus cuniculus ) and pink-footed shearwaters on Isla Robinson Crusoe. Introduced mammals observed, in order of greatest catch-per-unit-effort, were rats, cats ( Felis catus ), dogs ( Canis lupus familiaris ), and European hares ( Lepus europaeus ) on Isla Mocha and European rabbits, cats, cattle ( Bos taurus ), rats, dogs, mice ( Mus musculus ), and southern coati ( Nasua nasua ) on Isla Robinson Crusoe.
