Bird watchers arrive from all over the world in the hope of spotting some of the rarest birds on earth, amongst the 15 endemic species found only in the Seychelles. Several new species have been discovered by visiting bird watchers. The best birdwatching time is in April and May, which is the beginning of the breeding season for most seabirds. October is the best period to observe migrant birds.Virtually all endemic birds in the Seychelles are forest species and can be found on granitic islands, such as Praslin and Mahé. Some of these birds include the Seychelles Kestrel, Seychelles Blue-pigeon, Black Parrot, Seychelles Scops-owl, Seychelles Swiftlet, Seychelles Bulbul, Seychelles Magpie Robin, Seychelles Warbler, Seychelles Paradise-flycatcher, Seychelles White-eye, Seychelles Sunbird and the Seychelles Fody.
There are about 206 registered bird species in the Seychelles archipelago. Some of them, such as the Seychelles Paradise-flycatcher or the Seychelles Scops-owl with a size of 20cm, are difficult even for the most dedicated bird watcher to spot.
