What is "thick-billed parrot"

The thick-billed parrot (Rhynchopsitta pachyrhyncha) is a medium-sized green and red parrot found in Mexico, that formerly ranged into the southwestern United States. Its position in parrot phylogeny is the subject of ongoing discussion; it is sometimes referred to as thick-billed macaw or thick-billed conure. In Mexico, it is locally called guacamaya ("macaw") or cotorra serrana ("mountain parrot"). Classified internationally as Endangered through IUCN, the thick-billed parrot's decline has been central to multiple controversies over wildlife management.
