Control mammalian predators on islands for songbirds Bird Conservation

A before-and-after study on Frégate (210 ha), Seychelles, between 1981 and 1984 (Watson et al. 1992), found that the population of Seychelles magpie robins Copsychus sechellarum (a species confined solely to Frégate at the time) increased from 18 to 25 birds following the removal of at least 56 feral cats Felis cattus in 1981-2 and the probable eradication of cats from the island. The authors argue that a reduction in foraging habitat due to agricultural abandonment hindered further population growth.
