Conservation Status

Southern Bristle-Tyrant is considered Near Threatened at the global level (BirdLife International 2016). However, it is possible that its threat category is underestimated.

Effects of human activity on populations

Like other species of forest bird, Southern Bristle-Tyrant is vulnerable to habitat loss and fragmentation. A comprehensive analysis of the distribution of Southern Bristle-Tyrant was conducted by Tonetti (2015), who used ecological niche models to analyze the effects of habitat fragmentation and climate changes on the species potential distribution up to the year of 2070. Results indicated that Southern Bristle-Tyrant may lose 40% of its potential distribution under scenarios of global warming.
