Conservation of the surface-nesting Kermadec Petrel Pterodroma neglecta neglecta in the South Pacific: clarifying breeding ecology and the threat of avian ground predators

Successful management of invasive Purple Swamphens on Phillip Island significantly boosted breeding success of Kermadec Petrels from 25% to 56%, highlighting the critical impact of predator control on seabird conservation. The study identified that these surface-nesting petrels prefer sloping terrain (182–228 m above sea level) within 85 m of the coast, under low scrubby woodland, and exhibit year-round breeding with a peak in late austral spring. Prudent management of this population could support regional recovery efforts, including potential reintroduction to Lord Howe Island, while also aiding island restoration through increased marine-derived nutrient transfers. Adaptive management strategies will be essential to mitigate threats from native avian predators.
