The genus, Anodorhynchus Spix, 1824 [5] is one of six genera of Central and South American macaws in tribe Arini of macaws, parakeets and closely related genera. The macaws and parakeets comprise the clade of long-tailed parrots which with sister clade the short-tailed Amazonian parrots and allies make up subfamily Arinae of Neotropical parrots in family Psittacidae of true parrots.
It also contains the largest flighted parrot in the world, the hyacinth macaw. Some species, such as the blue-and-yellow macaw and sun conure are popular pet parrots. Molecular studies have dated the divergence of the Arini tribe from the ancestral neotropical parrots to late in the Paleogene period about 30–35 million years ago.

Many animals regularly visit mineral licks to consume clay, supplementing their diet with nutrients and minerals. In tropical bats, lick visitation is associated with a diet based on wild figs (), which have very low levels of sodium, [3] [4] and licks are mostly used by females that are pregnant or lactating.
Reported sightings of tool use in wild parrots go as far back as 1863. Examples of tool use that have been observed usually involve a chewed leaf or pieces of wood. Macaws often incorporate these items when feeding on harder nuts. Their use allows the nuts the macaws eat to remain in position (prevent slipping) while they gnaw into it.
