Great green macaw (Ara ambigua)

The great green macaw (Ara ambiguus) has a limited distribution in the Atlantic wet lowlands of Central America, from Honduras south to northern Colombia, with a small isolated population in the Pacific in Esmeraldas and Guayaquil, Ecuador. The world population is about 7.000 specimens. In Costa Rica, this species is currently limited to approximately 600 km2 of tropical very wet rainforest in the northern part of the country, in the area that borders Nicaragua. The species is highly dependent on the Almendro tree (Dipteryx panamensis) both for feeding and nesting. This endangered species, which is listed in Appendix I of CITES, is in serious danger of disappearing from Costa Rica in the near future.
