Pseudobulweria macgillivrayi
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Pseudobulweria macgillivrayi faces severe threats from introduced predators, particularly cats and rats, which prey on eggs, chicks, and potentially adults at breeding colonies. Habitat degradation from human development and agricultural expansion has reduced available nesting sites on Pacific islands. Light pollution from coastal development disrupts the species' nocturnal behavior and navigation, leading to disorientation and mortality of fledglings.
Habitat
This seabird inhabits tropical and subtropical Pacific Ocean waters, coming to land only to breed on remote islands with suitable nesting habitat. Breeding occurs in burrows or crevices on forested slopes and clifftops of oceanic islands.
