A few kilometres from Praslin is the small island of Cousin. Cousin is a bird sanctuary and can be visited by arrangement. It is about one and a half hours from Praslin by boat.
The island is owned by the Royal Society for Nature Conservation (RSNC), administered by the International Council for Bird Preservation (ICBP). Cousin extends over 27 hectares and is entirely dedicated to nature. In fact, the island was made a nature reserve in 1968, when it was bought by the RSNC as a haven for endangered species of land and sea birds. Furthermore, the Seychelles Government declared it a Special Reserve in 1975, thus offering all the wildlife on the island legal protection.
Amongst the species to see are the Seychelles fody, the Seychelles turtle dove, the white-faced tropic bird, The wedge-tailed shearwater, the fairy tern, noddies and bridled terns. The Seychelles brush warbler can be found only on Cousin, Krk island and Aride island.
