Tanimbar Corella Cacatua goffiniana



Justification

Justification of Red List Category
This species has a very small range, but its population is not severely fragmented or restricted to a few locations. Despite suffering heavy trapping pressure it appears to have maintained a large population. However, habitat degradation, continued trapping and persecution are likely to be causing a moderately rapid population reduction and it therefore qualifies as Near Threatened.

Population justification
The global population has been estimated to number c.100,000-499,999 (BirdLife International 2001), while the population in Taiwan has been estimated at < c.100 introduced breeding pairs (Brazil 2009).

Trend justification
There are few data on population trends; however, the species is suspected to be declining at a moderately rapid rate, owing to trapping and habitat degradation.

Distribution and population

Cacatua goffiniana is restricted to the Banda Sea Islands of Yamdena and Larat (Tanimbar) with an introduced population on Kai, Indonesia. In the 1980s the numbers of birds entering trade annually exceeded 10,000 in some years and there were fears for its security, but the total population is estimated to number 300,000-400,000 individuals.

Ecology

It inhabits forest and agricultural land, feeding on maize crops and roosting in the forest.

Threats

Habitat loss continues apace in the south of Yamdena and this, combined with continued trapping, must be producing a decline. It may be persecuted as a crop pest or hunted for food in some areas.

Conservation actions

Conservation Actions Underway
CITES Appendix I (1992).

Conservation Actions Proposed
Regularly monitor at certain sites throughout its range to determine population trends. Investigate the extent of trapping and persecution and take appropriate measures, including the use of awareness campaigns, to address these issues. Protect significant areas of suitable forest on all islands where it occurs.
