Population [top]

Population: It is not a common species, occurring at low densities. Its population was estimated at 2,055 ± 620 animals in 2005 (Gerlach in prep).
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It is an arboreal species in tropical forest, being present in both primary forest and upland rural gardens. It also occurs in secondary forest but only if there is a high plant diversity. Its reproduction on Mahé is associated with introduced pineapple plants as it lays its eggs in these. These pineapples are not used on Silhouette or Praslin. Its natural nesting sites remain unknown but are assumed to be in the endemic Pandanus and palms.
Systems: Terrestrial

Threats [top]

Major Threat(s): The main threat is habitat degradation as a result of the invasion by alien plants species, especially Cinnamomum verum, principally on Mahé and Praslin.

Conservation Actions [top]

Conservation Actions: It is present in the Morne Seychelles and Praslin National Parks. Forested areas where the main population occurs on Silhouette island should receive legal protection. It is included on Appendix II of CITES.
