Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2012
Date Assessed: 2012-05-01
Assessor/s: BirdLife International
Reviewer/s: Butchart, S. & Symes, A.
Facilitator/s: Symes, A., Calvert, R.
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). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very 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.

Geographic Range [top]

Range Description: The Kermadec Petrel ranges across the southern Pacific, from Lord Howe Island (Australia) and the Kermadec Islands (New Zealand) in the west to San Ambrosio Island, Chile in the east. Outside the breeding season it ranges over much of the tropical and subtropical Pacific, occuring in the north Pacific mainly between November and January (del Hoyo et al. 1992).

Population: Brooke (2004) estimated the global population to number 150,000-200,000 individuals.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: This species is marine and highly pelagic, rarely approaching land except at colonies. Little is known about its diet, though squid and crustaceans have been recorded as prey. The breeding season is variable depending on locality, forming loose colonies on offshore islands, occupying cliffs or slopes with some vegetation (del Hoyo et al. 1992).
