Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

The Greater Ani faces significant population declines primarily due to widespread deforestation and habitat fragmentation across its Amazonian range. Agricultural expansion, particularly cattle ranching and soy cultivation, has eliminated vast areas of the riparian forests and woodland edges this species requires. Climate change compounds these pressures by altering precipitation patterns that affect the wetland ecosystems where Greater Anis forage for insects and small vertebrates.

Threat summary

Habitat

Greater Anis inhabit riparian forests, woodland edges, and gallery forests along rivers and wetlands throughout the Amazon Basin. They prefer areas with dense canopy cover near water sources, where they forage cooperatively in small flocks for insects, small reptiles, and amphibians.
