The yellow-collared macaw or golden-collared macaw (Primolius auricollis) has a bright yellow patch on the back of its neck/upper shoulders that gives the species its name. It is a small mostly green Central South American parrot ranging from northern and eastern Bolivia, ranging eastwards into Brazil and southwards into northern Paraguay and northwestern Argentina. Its specific epithet auricollis means gold-collared, from the Latin aurum 'gold', and collum 'neck'. This Macaw occurs in varying types of habitat, ranging from humid upper tropical forest at the base of the Andes, through deciduous chaco woodlands. Primarily a bird of the lowlands, it does occur up to about 2,000 feet in northwestern Argentina.
