Red-tailed Amazon are usually found in pairs or flocks, which may reach heights of over 400 individuals in winter (2) (5). Daily migrations allow the red-tailed Amazon to feed on the abundant mainland, while roosting and breeding on the coastal islands (5). From mid morning until dusk, this bird forages primarily for fruit, although it also feeds on seeds, leaves, flowers, nectar and insects within the fruit (2) (5).
The breeding season takes place from September to February, with up to four eggs per clutch laid in nests in natural tree cavities (4) (5). Eggs are incubated for 27 to 28 days, and the fledging period is thought to last from 50 to 55 days (2) (5).
