Control mammalian predators on islands for seabirds
A before-and-after study on Isla Isabelle (194 ha), western Mexico (Rodriguez et al. 2006) found that mortality rates of adult sooty terns Onychoprion fuscata fell from an estimated 23-33% of the nesting population over the breeding season in 1991-4 to 5% in 1996 and then to 2% in 2002-4, following the eradication of cats Felis catus through trapping, poisoning (with 1080 sodium monofluoroacetate) and shooting. An attempted eradication of black rats Rattus rattus at the same time, using brodifacoum poisoning failed.
