Control mammalian predators on islands for seabirds
A before-and-after study on the sub-Antarctic Marion Island (290 km2), South Africa (Cooper & Fourie 1991), found that breeding success of great-winged petrels Pterodroma macroptera, increased from 0-21% to 56-60% following 14 years of cat Felis catus control. In addition, no signs of cat predation were found in 1990, but at least 28% of chicks were predated in 1983. Nests were monitored in 1979-80, 1982 and 1984 (between 17 and 53 nests studied) and in 1990 (50 nests). Control consisted of the release of the disease panleucopaenia, shooting and trapping.
