The red-spectacled Amazon breeds in the latter part of the year, typically from late September through until January (6). During this time it is seen in pairs, and tends to move about quietly and vocalize less, presumably to avoid attracting attention to the nest site (11). In captivity, incubation periods of between 26 and 30 days have been recorded (11). Nests are made in hollow trees (9), and local people report that between two and four young are raised, fledging by late December (11).
Outside of the breeding season, the red-spectacled Amazon travels in noisy flocks of up to 150 birds, which roost together in large numbers at night (11). Migrating seasonally to feed on the mass-produced seeds of the Critically Endangered Brazilian pine (Araucaria angustifolia) (10), the red-spectacled Amazon also feeds on a variety of other seeds, fruits and flowers (6).
