The conservation status of Tanimbar corella and blue-streaked lory on the Tanimbar Islands, Indonesia: results of a rapid contextual survey

Two parrot species, Tanimbar corella Cacatua goffini and blue-streaked lory Eos reticulata, endemic to the Tanimbar Islands, Indonesia, were regularly trapped and sold into the international wild bird trade prior to 1992. Following concerns about numbers entering the trade, but with little knowledge of the remaining wild population or socio-economic role of bird trapping on the islands, international trade in both species was suspended at the 1992 CITES meeting. This paper reports on a rapid survey conducted on the islands in 1993 as a follow-up to the decision on trade. The survey attempted to determine the status of the wild populations, the distribution and activity of the human population, the interaction between Tanimbar corella and agriculture, and the structure of the local commodity-chain for wild-caught parrots. We found that: (a) both parrot species were widely distributed and present at relatively high densities across the largest island in the group, Yamdena; (b) catching of parrots is geographically limited; (c) in the case of Tanimbar corella, at least, the catching is of birds raiding crops and probably involves mainly immature and non-reproductive birds; (d) the international and domestic ban on catching was generally adhered to locally but the reasons for the ban were not widely understood, contributing to a general mistrust of conservationists that still remains. Although not advocating a lifting of the ban on trapping, we do conclude that in this case invoking the precautionary principle without proper consideration of local context may have been counter-productive to conservation goals.
