Abstract

This study examines the distribution of Wedge-tailed Shearwater Ardenna pacifica along the northwest coast of South America. The species is well known in tropical waters distant from the coast, but it also appears to be a regular visitor to shelf-break waters off Colombia and northern Ecuador; there is no evidence indicating a similar presence within the exclusive economic zone (EEZ) of Peru, where waters are colder. About 50% of Wedge-tailed Shearwater sightings are associated with dolphins and/or large fish. More than 90% of the nearshore South American records are of pale-phase individuals.
