Overview

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

The Rufous Casiornis faces severe pressure from widespread deforestation and agricultural expansion throughout its range in South America's Atlantic Forest and Cerrado regions. Cattle ranching and soybean cultivation have eliminated vast areas of the dry forests and woodland savannas this species requires for nesting and foraging. Climate change compounds these threats by altering precipitation patterns in already fragmented habitats, while the species' specialized insectivorous diet makes it particularly vulnerable to ecosystem disruption.

Threat summary

Habitat

The Rufous Casiornis inhabits dry forests, woodland savannas, and gallery forests across South America's Atlantic Forest and Cerrado biomes. It prefers semi-open areas with scattered trees and dense understory vegetation where it can hunt for insects and establish territories.
