According to a recent release, the US Fish and Wildlife Service has listed the hyacinth macaw – the largest species of parrot in the world – as a threatened species under the Endangered Species Act (ESA)
In the last decade the Lear’s macaws have faced increasing competition for their nesting cavities. This competition is not from other birds, or even mammals, but from an insect. The invasive Africanized Honey Bees (AHB) have steadily increased in number and are excluding macaws from cliff cavities, limiting their breeding success. These bees are also promoting habitat destruction, poaching, and they pose a risk to the scientists studying the macaws.
