Blue-throated Macaw
The Blue-throated Macaw is endemic to the Bolivian Beni savanna ecoregion, also known as Los Llanos de Moxos. This Macaw is Critically Endangered and only 200-250 individuals are expected to survive in the wild. It inhabits hyper-seasonal flooded savanna habitat, interspaced with Motacu dominated palm forest islands and gallery forest, which it uses to forage and roost. The species experienced severe population declines and local extirpation due to illegal pet trade and habitat loss.
