Conservation
CITES: Appendix II
IUCN STATUS CATEGORY: Critically
Endangered
CURRENT POPULATION Around 25
birds survived in the wild in the mid 1990s, with another introduced population,
based on captive-bred birds, numbering around 52. Captive population over
220 in 1996
PREVIOUS GEOGRAPHICAL SPREAD
Formerly more widespread in Mauritius.
REASONS FOR DECLINE The species
seems always to have been local, but decline is attributed to habitat
loss, food shortage, nest predation and natural disasters, particularly
cyclones. Now also greatly
at risk because small population size itself increases the likelihood
of chance factors affecting the species.
CONSERVATION PROJECTS Between
1987 and 1992, a total of 51 captive-bred birds were released into apparently
suitable habitat at Brise Fer. Supplementary feeding and rat control around
both the wild and introduced populations have much improved the species'
status. By May 1994 the introduced population stood at 52 birds, half
born in the wild, and the original wild population at around 25. The release
programme is being extended. The Cryptomeria grove used by the wild population
is now within the Black River National Park.
