Subspecies
Polytypic and, in Central America, apparently polymorphic. Often broken down into three species: Yellow-headed Amazon (Amazona oratrix), incorporating tresmariae and belizensis; Yellow-naped Amazon (Amazona auropalliata), incorporating caribaea and parvipes; and Yellow-crowned Amazon (Amazona ochrocephala) incorporating panamensis, xantholaema and nattereri. However, considerable variation and overlap in characters exist in populations in and adjacent to Honduras, such that no very coherent species limits can be set at any point between oratrix to the northern and panamensis to the south. Possibly the clearest-cut step would involve separating oratrix and tresmariae, thus transferring belizensis to the ochrocephala group. On present knowledge, entire complex is probably best regarded as a single species. Patterns of variation remain unclear and birds of extreme eastern Guatemala may be separable as subspecies guatemalensis and those of north-western Honduras as hondurensis. Both of these forms appear closer to oratrix group than to auropalliata group.
Considered by some authors to be a subspecies of Yellow-crowned Amazon (Amazona ochrocephala).
The following 3 subspecies are recognised:
auropalliata (Lesson, 1842) - Southern Mexico south to north-western Costa Rica. Considered by some authors to be a subspecies of Yellow-crowned Amazon (Amazona ochrocephala).
caribaea Lousada, 1989 - Bay Is, Honduras. Considered by some authors to be a subspecies of Yellow-crowned Amazon (Amazona ochrocephala).
parvipes Monroe and Howell, TR, 1966 - North-eastern Honduras and northern Nicaragua. Considered by some authors to be a subspecies of Yellow-crowned Amazon (Amazona ochrocephala).
