The Seychelles parakeet (Psittacula wardi) occurred in the Indian ocean islands of the Seychelles group. It resembled the Alexandrine parakeet but was smaller and lacked the pink colour in its collar. The species is suspected to have become extinct due to intense persecution by farmers and coconut plantation owners.
Phylogenetic studies suggest that the species diverged from the Alexandrine parakeet through isolation of populations that dispersed through the Indian Subcontinent into Seychelles about 11 million years ago when sea levels were much lower.
It was endemic to Mahé and Silhouette and was once sighted on Praslin. It was rare when described even in 1867. The last specimens were collected by Warry in 1881, and the last birds recorded in captivity on Silhouette in 1883. Ten specimens exist today. The species was extinct by 1906.
Behaviour and ecology
The Seychelles parakeet had a diet of bugs found in the bushes or trees.
