Translocate rails
A review of a translocation programme for white-throated (Aldabra) rails Dryolimnas cuvieri (formerly D. aldabranus) on Aldabra atoll, Seychelles, in 1999-2001 (Wanless et al. 2002) found that all 18 birds successfully released survived from November 1999 until at least April 2000, with 17 being seen again between December 2000 and April 2001 (the remaining bird was recorded in an inaccessible part of the island). An estimated 15-16 chicks fledged in 1999-2000, with all known mortality (30%) occurring within three weeks of hatching. In 2000-1 at least 20 chicks were fledged, leading to a minimum population of 51 birds, an increase of 183% in 18 months. Birds were transported from Île Malabar during pair formation and transferred to Île Picard within three days. There, birds were held in 30 m2 enclosures near good quality habitat and provided with shelter, fresh water and food for six or 14 days before release. Food was provided to birds that stayed in or around the cages after release.
