The foraging ecology of Peruvian seabirds

Open access
Duffy, David Cameron·1983·The Auk

Abstract

Most feeding by seabirds in the Peruvian Coastal Current, an upwelling of high productivity off the west coast of South America, takes place in groups. The major prey is an anchovy (Engraulis ringens), which occurs in large shoals and is exploited mainly by three species: the Peruvian Booby (Sula variegata), Peruvian Brown Pelican (Pelecanus occidentalis thagus), and Guanay Cormorant (Phalacrocorax bougainvillii). Other foraging situations have different species' compositions, and these appear to be related to the size, depth, and duration of availability of prey. Dominance interactions between species may be important in structuring flocks that are scavenging or feeding on plankton swarms. Interspecific piracy seems unimportant in flocks foraging on fish shoals. Certain species usually arrive first at new feeding situations. These species may be used as guides by other species or merely may be faster and thus reach food sources first. Studies of foraging of seabirds should be a valuable addition to the study of the distribution of birds at sea.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Breeding success is most affected by group composition variables rather than enclosure parameters.

    “Our observation that breeding success is most affected by group composition variables rather than enclosure parameters, supports previous work (Blay and Cote, 2001) and reflects the high degree of sociality expressed by S. humboldti (Duffy, 1983).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
