The Great Green Macaw mainly inhabits humid forests below 600 meters. The mountain almond tree is the key to the species, and selective logging has contributed greatly to the rapid and continuous decline experienced in wild populations of this bird, which has become scarce in four of the six countries in which it is distributed.
Conservation status: EN (Endangered) on the IUCN Red List
Wild population: 3,700 declining.
Captive population: Number unknown
Discover new aspects of the biology and ecology of the species in south-eastern Nicaragua and northern Costa Rica, and promote the protection of the species and its habitat.
This is a research project integrated into other work for the conservation of this area of great ecological wealth, which is at a critical juncture of the Mesoamerican Biological Corridor and has two important protected areas: the Indio-Maiz Reserve, Nicaragua and Braulio Carrillo National Park in Costa Rica. The study of the migration of this species is considered fundamental.
The work has included the study of reproductive activity through observation and monitoring of nests, and banding and monitoring of adult individuals to improve knowledge of the migration range. Although in general the species faces a difficult situation, the censuses show that the population is increasing in the project region. The life cycle of the preferred trees of the Great Green Macaw and the training of young biologists in the field of conservation have been other courses of action. The project has also conducted an awareness campaign with this bird as the emblem.
