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
