A before-and-after study from September 1988 to January 1993 in the Seychelles (Komdeur 1997) found that all 29 Seychelles warblers Acrocephalus sechellensis translocated from Cousin Island to each of Aride Island (in September 1988) and Cousine Island (in June 1990) were alive in 1991 and that populations had grown from before translocations to 210 on Aride Island and 53 on Cousine Island. A further census on Aride Island in January 1993 estimated a population of 239 warblers. Prior to translocation, potential introduction sites were identified according to food availability, the absence of feral cats Felis catus and black rats Rattus rattus, and a sustained commitment to conservation management from the land owners. Translocation was in well-ventilated cardboard cages (15 × 15 × 20 cm) with a stick trellis 1 cm above the floor of each box allowing birds to perch, and the entire process of capture, translocation and release took on average little more than three hours, with no mortalities.
