Hypomasticus thayeri

Declining

Overview

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

Hypomasticus thayeri faces significant pressure from deforestation and habitat fragmentation across its range in the Amazon Basin. Agricultural expansion, particularly cattle ranching and soy cultivation, has reduced available forest cover in key areas. The species' dependence on specific forest microhabitats makes it particularly vulnerable to logging operations that alter forest structure and canopy composition.

Threat summary

Habitat

This species inhabits lowland tropical rainforests of the Amazon Basin, typically found in the understory and middle canopy levels. It shows preference for primary forest areas with dense vegetation cover and appears to require specific microhabitat conditions within mature forest ecosystems.
