Overview

Distribution

Range Description

The Thin-billed Prion breeds the Crozet Islands and the Kerguelen Islands (French Southern Territories), the Falkland islands (Islas Malvinas) and Noir Island, Chile. Outside the breeding season it can be found over much of the Southern Ocean, including the coasts of South Africa, Australia and South America as far north as Uraguay and southern Peru1.

Ecology

Habitat

Habitat and Ecology

Habitat and Ecology
This marine species can usually be found over pelagic waters but will feed inshore or in shallow offshore waters during the breeding season. It feeds mostly on crustaceans with a heavy dependance on amphipods (particularly Themisto gaudichaudii). It can also take small fish and squid. It catches prey mainly by surface-seizing, dipping and pattering at night. Breeding starts in October in loose colonies in costal areas with soft or stony soil and low vegetation. It nests in burrows (del Hoyo et al. 1992).

Justification
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is extremely large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
