Taxonomy
The Golden-collared Macaw was described by American ornithologist John Cassin in 1853. Its specific epithet auricollis meaning gold-collared, from the Latin aurum 'gold', and collum 'neck'. In recent years it has often been placed in the genus Propyrrhura, but this is incorrect as per ICZN rules. Earlier, it had also been placed in the genus Ara.
