This species was endemic to the island of Rodrigues, Mauritius, but it has not been recorded since 1875 and is now Extinct. It is thought that hunting and habitat loss were major contributors to its decline, and that the final blow may have been dealt by vicious storms in 1876.

Geographic Range [top]

Range Description:Psittacula exsul was endemic to forests on Rodrigues, Mauritius (Cheke 1987). It was said to be abundant by Leguat in 1691 (Cowles 1987), but Pingré noted that it was scarce by 1761, and the last record was a bird collected in August 1875 (Forshaw 2010). It seems probable that the last few were wiped out later that year, when the island suffered 'the worst cyclonic season of the 19th century' (Cheke 1987). Two complete specimens survive, plus various subfossil bones (Cowles 1987).
