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/Compiler(s): Ekstrom, J., Butchart, S., Calvert, R.
Justification:
This species has a very 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 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.

Habitat and Ecology [top]

Habitat and Ecology: The Blue-footed Booby is strictly marine, feeding in adjacent inshore waters, tending to exploit cool, rich waters in areas of upwelling. It specialises in catch fish by plunge-diving, often in unison, catching sardines, achovies and mackerel, but also flying-fish and squid. It has been seen fishing in the company of dolphins and the Peruvian Booby. Breeding is seasonal in places and otherwise opportunistic, nesting on cliffs and islets in areas with little or no vegetation (del Hoyo et al. 1992).
Systems: Terrestrial; Marine
