  1. Control mammalian predators on islands for parrots

    A before-and-after study on Raoul Island (2,938 ha), Kermadec Islands, New Zealand (Ortiz-Catedral et al. 2009) found that the island was recolonised by Kermadec red-crowned parakeets Cyanoramphus movazelandiae in 2008, following the eradication of goats Capra hircus by hunting (in 1986) and cats Felis cattus, brown rats Rattus norvegicus and black rats R. rattus by poisoning and hunting (between 2002 and 2004). In 2008 the parakeet population was at least 100 individuals, of which 44 were born in 2008. Before this, parakeets had been absent for 172 years.
