Found in humid lowland forests from Mexico to Bolivia, they are highly intelligent, long-lived — up to 75 years — and form lifelong pair bonds. They travel long distances to clay licks where they consume mineral-rich soil to detoxify seeds. Listed as Least Concern but locally threatened by habitat loss and the pet trade.
