Another subspecies, shown above centre and right, from Belize (A. o. belizensis), sometimes has just a yellow crown, leading to confusion with the Yellow-crowned Amazon, and a further subspecies (not shown), from Honduras (A. o. hondurensis), has only yellow crown and nape, leading to confusion with the local Yellow-naped subspecies.
