Overview

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

The Rufous-rumped Seedeater faces severe pressure from widespread conversion of its grassland habitats to agricultural land, particularly cattle ranching and soybean cultivation across its South American range. Habitat fragmentation has isolated remaining populations, while the species' specialized diet of grass seeds makes it particularly vulnerable to changes in grassland composition from overgrazing and invasive plant species.

Threat summary

Habitat

This seedeater inhabits natural grasslands, savannas, and campo rupestre (rocky grasslands) across parts of Brazil, Bolivia, and Paraguay. It shows a strong preference for areas with diverse native grass species that provide the small seeds essential to its specialized diet.
