These near-identical parrots prove that birds of a feather flock together. But sometimes that feather is hard to put a name to, especially in the crowded world of amazon parrots. Most amazons share the genus' most visible trait—green plumage. Subtle differences in head, wing and beak colouration, however, result in a spread of about 30 species. That makes it tough to precisely identify amazons in the wild, although we're pretty sure our bird buddies here are yellow-crowned amazons. Would you like to do a little field research and see if you agree?
