This time of year, from October through December, Great Green Macaws (Ara ambiguus) return to the
Maquenque National Wildlife Refuge in northern Costa Rica from the Indio Maiz Biological Reserve in Nicaragua. Following their main food source of mountain almond tree fruits that are now in season, the Macaws return to this vital habitat of rainforest and wetlands in Costa Rica.
The Maquenque National Wildlife Refuge preserves nearly 150,000 acres that contain mountain almond trees (Dipteryx panamensis) which endangered Great Green Macaws use for food and nesting. Formed in June 2005, the refuge is one of the biggest habitats for Great Green Macaws in Costa Rica, and is an important part of the Mesoamerican Biological Corridor.
Great Green Macaws are only found in the Atlantic wet lowlands of Central America, from Honduras to northern Colombia, with a small isolated population in Ecuador. Loss of habitat and logging of mountain almond trees has largely caused their population to decline to only between 1,800 to 2,500 mature Great Green Macaws left in the world, according to Bird Life International.
