In order to determine whether Aratinga erythrogenys and Brotogeris pyrrhopterus can formally classified as globally threatened species, their distribution, population sizes and ecological requirements are reviewed, together with national and international trade data from the last decade. The study concludes that, on current data, it is not possible to classify the two species formally, but there are strong indications that, at least locally, the populations of the two species are in decline. The causal factors appear to be a combination of high trade levels and habitat loss. It is essential that trade moratoria are implemented, pending the outcome of further research into the species' population sizes, ecology and breeding success, and further work to determine the extent of trade. Interim recommendations are given and it is proposed that future exploitation of the species should continue only when it has been determined that it has a sustainable basis.
