Bird Island, famous for its population of dugongs or sea cows, was once referred to as Îles aux Vaches. The island is home to a massive population of sooty terns. The migratory birds increase their numbers to exceed one million during their breeding season from May to October. Needless to say, Bird Island is a top destination for bird watchers and nature photographers. In addition to sooty terns, the island is also home to giant land tortoises, cardinals, noddy terns, mynahs, ground doves, plovers and crested terns. Travellers can also enjoy big game fishing at the nearby Seychelles Bank.
