The initial journey of an endangered penguin: implications for seabird conservation
Open accessAbstract
Seabirds can disperse widely in search of prey, especially during non-breeding periods. Conservation measures predominately focus on protecting breeding colonies, but juvenile survival and recruitment can have critical impacts on population dynamics. We report the first deployment of satellite transmitters to track the dispersal of fledgling African penguins Spheniscus demersus, a step towards determining the at-sea behaviour of post-fledging birds and identifying the key non-breeding habitats for this species. Five hand-reared fledglings dispersed from their release sites in the Western Cape, South Africa, in a north-westerly direction. Birds moved >100 km within 6 d and reached a mean distance of >1000 km from their release sites. Two key foraging areas were identified in regions of high and reliable primary productivity, one around Swakopmund, Namibia, and one north of Lambert’s Bay, South Africa. Neither site has protected status, underlining the importance of adaptive strategies to preserve key foraging hotspots and the need for further information on post-fledging dispersal to improve seabird conservation.

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.
