Cape gannets Morus capensis are predatory seabirds in
the coastal waters of southern Africa where they feed
on commercially important fish species. Using a
combination of intensive monitoring at nest sites,
tracking of radio-tagged birds and diet sampling, we
determinedthe foraging ranges and foraging areas used
by breeding gannets,and whether links existed between
the broad-scalespatial distribution of foraging birds and
the distribution of prey or the predominantwind regime.
