|A Scarlet macaw in flight|
Macaws, like all parrots, are unusually intelligent birds. The usual thing for parrots is to pair for life. They stay together even out of the mating season. They often fly in formation, one above the other.
Diet and clay licksEdit
Macaws eat a variety of foods including seeds, nuts, fruits, palm fruits, leaves, flowers, and stems. Wild species may forage widely, over 100 km (62 mi) for some of the larger species such as Ara araurana (blue & yellow macaw) and Ara ambigua (great green macaw), in search of seasonally available foods.
The clay eating behavior of parrots was studied at clay licks in Peru. Apparently, macaws and other birds and animals prefer clays with higher levels of salt. Sodium is a vital element which is scarce in environments over 100 kilometers from the ocean.
