The Thick-Billed Parrot is considered as the lone existing parrot species that is endemic to the south-western part of the United States. This North American psittacine bird is also known as Thick-Billed Macaw or Thick-Billed Conure. Together with Painted Redstart, Varied Bunting, and Violet-Crowned Hummingbird, the Thick-Billed Parrot belongs to a bird group that prefers high mountain ranges or sky islands.
The thick-billed parrot is a medium-sized, bright green parrot with a large black bill and red forecrown, shoulder and thighs. Adult eyes are amber, while juveniles have brown eyes. The rest of the bird is bright green. Thick-billed parrots show red shoulders and leading edge on the underwing, followed by a blackish green stripe, then a yellow stripe, followed by the remaining underwing showing dark green.
As more and more large-diameter trees are targeted by logging companies, there are fewer suitable habitat options for the Thick-Billed Parrot. Lumbering activities either destroy the nests or force the parrots to abandon the area completely. Increasing fire threats and thicker snow due to hotter temperatures also makes it difficult for them to find nesting and roosting sites that are not accessible by predators and poachers.
