Overview

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

Torrent Ducks face mounting pressure from hydroelectric development across their Andean range, with dam construction fragmenting their specialized fast-flowing river habitats. Mining activities and agricultural runoff degrade water quality in their pristine mountain streams, while climate change alters precipitation patterns that maintain the torrential flows essential for their feeding behavior. Habitat conversion for agriculture and livestock grazing along riverbanks further reduces available nesting sites and increases human disturbance.

Threat summary

Habitat

Torrent Ducks inhabit fast-flowing, rocky mountain streams and rivers throughout the Andes, from Venezuela to Argentina, typically at elevations between 1,500-4,500 meters. They require pristine, oxygen-rich torrential waters with boulder-strewn beds that provide both feeding opportunities for aquatic invertebrates and secure nesting sites in rock crevices.
