Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

De Filippi's Petrel faces severe threats from introduced predators, particularly cats and rats, on its breeding islands off the Chilean coast. The species' extremely restricted breeding range makes it highly vulnerable to habitat degradation and human disturbance at nesting sites. Climate change poses additional risks through altered ocean conditions that may affect prey availability and breeding success.

Threat summary

Habitat

This seabird breeds exclusively on remote offshore islands along the Chilean coast, nesting in burrows on steep slopes and clifftops. At sea, it forages in pelagic waters of the southeastern Pacific Ocean, typically in areas with upwelling currents rich in squid and small fish.
