This week BirdLife International and Nature Seychelles (BirdLife in Seychelles) are celebrating the anniversary of one the world’s greatest conservation success stories. In 1968, Cousin Island was purchased by the International Council of Bird Preservation (ICBP now BirdLife International) to save the last remaining population of Seychelles Warbler Acrocephalus sechellensis from extinction. Forty years on, warbler numbers have risen by 300%, and the island has been transformed from a coconut plantation to a profitable Nature Reserve which greatly benefits local people and global biodiversity.
Cousin Island – a small island in Seychelles - is today home to a wealth of globally important wildlife. It is the most significant nesting site for Hawksbill Turtle Eretmochelys imbricata in the Western Indian Ocean, and supports over 300,000 nesting seabirds of seven species. Cousin also hosts five of the Seychelles’ eleven endemic land-birds including: Seychelles Magpie-robin Copsychus seychellarum (Endangered), Seychelles Sunbird Nectarinia dussumieri, Seychelles Fody Foudia seychellarum and Seychelles Blue-pigeon Alectroenas pulcherrima.
Until 1968 Cousin was a coconut plantation which had lost most of its native vegetation. The Seychelles Warbler was almost extinct and fewer than 30 birds remained in the world; being confined mostly to a mangrove swamp on Cousin. In response, ICBP launched a world wide campaign and bought the island with the aim of saving the warbler. That year Cousin was declared a legally protected Nature Reserve by the Seychelles Government.
“Seychelles Warbler population was so small that a single severe climate, disease or man made event could have caused their extinction”, said Dr Mike Rands – BirdLife’s CEO and Director. “Transformation from a coconut plantation to an ecologically-restored island was achieved through careful habitat management and preventing alien predators - such as rats - from arriving”.
