Diet:

Fruit such as: apple, pear, orange, banana, cactus fruits, pomegranate, forming about 30% of the diet; fresh vegetables such as: carrot, celery, green peas, beans, fresh corn, green leaves; spray millet and limited mixed seed, cooked beans and pulses, complete kibble.

IUCN Red List Status:
Least Concern

CITES Listing:
Appendix II

As congener of Amazona autumnalis

Threat Summary:

This species’ population is expected to decline due to ongoing deforestation in the Amazon basin. It is also susceptible to trapping for local trade. Remote-sensed data shows four percent of forest with at least 50% canopy was lost within the species’ range between 2001 and 2019. Assuming a similar rate over the past three generations, this would equate to a reduction of around 8% habitat loss over 35 years.

Range:

Amazon basin of Brazil between Río Negro and Río Solimões.

Habitat:

Recorded in humid forest and forest margins.

Wild Diet:

Feeds mainly on wild and cultivated fruits (including Tetragastris), nuts and seeds.

Ecology and Behaviour:

Assumed to be similar to Red-lored Amazon: Found in loose flocks or in pairs, are gregarious when feeding (often found with macaws or other parrots). Occupies nocturnal roosts.

Clutch and Egg Size:

2-3

Breeding Season:

Assumed to be early in the year: January-March
