Abstract
All
of the fish identified in stomach contents and regurgitations of breeding and
chick Cape petrels collected during January and February 1996 at Fildes
Peninsula and Harmony Point, both in the South Shetland Islands and at Laurie
Island, South Orkney Islands, were myctophids, a family never reported in the
diet of breeding Cape petrels. Electrona
antarctica was the most important fish prey, followed by Electrona carlsbergi at Fildes
Peninsula, Krefftichthys anderssoni
at Harmony Point and Gymnoscopelus
braueri at Laurie Island. The absence of Pleuragramma antarcticum in the diet of this petrel, which is
considered a P. antarcticum-feeder,
is discussed.
