Translocate songbirds Bird Conservation

A before-and-after study on Cousin Island, Seychelles (Lopez-Sepulcre et al. 2008), found that the population of Seychelles magpie-robins Copsychus sechellarum increased from five individuals, translocated from Frégate Island in 1994-5, to 46 individuals in 2006, before declining to 31 birds in 2007. Two males and two females were originally moved, plus a replacement female following the death of one of the original females in early 1995. The birds were kept in individual holding aviaries for two days before translocation. Cousin Island was identified as a suitable introduction site based on its status as a nature reserve, the absence of invasive predators, and the availability of large areas of native forest and food resources.
