From December 1973 to March 1975, the food of feral cats (
Felis catus) was studied at Macquarie Island; during the 1974-75 and 1975-76 summers, the food of Great Skuas (
Stercorarius skua lonnbergi) was also partly studied. Data were obtained on the numbers, species and locations of remains of burrow-nesting petrels left by these two predators. Seven species of burrow-nesting petrels were identified from the remains found. These results when considered with previous records of burrownesting petrels at Macquarie Island indicate their status, relative abundance and distribution.
