Eriolarynx iochromoides

Declining

Overview

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

Eriolarynx iochromoides faces severe population decline primarily due to extensive deforestation and habitat fragmentation across its limited montane forest range. Mining activities and agricultural expansion have eliminated critical breeding territories, while climate change is shifting suitable habitat zones to higher elevations beyond the species' adaptive capacity. The species' highly specialized ecological requirements and small population size make it extremely vulnerable to any further habitat disturbance.

Threat summary

Habitat

This species inhabits humid montane forests and cloud forest edges at elevations between 1,500-2,800 meters in the Andes. It requires dense canopy cover with abundant epiphytic vegetation and maintains territories near permanent water sources in steep-sided valleys.

Frequently asked questions

Why is Eriolarynx iochromoides classified as Critically Endangered?
Eriolarynx iochromoides is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Eriolarynx iochromoides faces severe population decline primarily due to extensive deforestation and habitat fragmentation across its limited montane forest range. Mining activities and agricultural expansion have eliminated critical breeding territories, while climate change is shifting suitable habitat zones to higher elevations beyond the species' adaptive capacity. The species' highly specialized ecological requirements and small population size make it extremely vulnerable to any further habitat disturbance.
Where does Eriolarynx iochromoides live?
Eriolarynx iochromoides occurs in Argentina. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Eriolarynx iochromoides?
The main threats to Eriolarynx iochromoides are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
