Conservation status

Internationally, Black-chested Tyrants is currently listed as Least Concern by Birdlife International (2011).

Effects of human activity on populations

The Black-chested Tyrant is projected to lose between 33 and 40% of suitable habitat within its distribution over three generations (11 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). This would result in a projected decline of ≥30% over three generations suggesting that the species should be uplisted from Least Concern to Vulnerable. In a large-scale assessment of biodiversity responses to land use change in the eastern Brazilian Amazon (Paragominas, Pará; A. C. Lees, unpublished data), however, the species was found to exhibit a wide tolerance to different forest types, occupying both undisturbed and disturbed (burnt and logged) primary forest and even young secondary forests. The species was relatively rarely encountered in pristine terra firme forest environments in Paragominas and probably benefits from moderate forest disturbance (but obviously not from total forest loss) as burnt and selectively-logged forests are often vine-dominated in the region. Likewise regenerating forest landscapes also offer a suitably dense understory structure that appears to be to this species’ liking, indicating that this species is less threatened by land-use change than many Amazonian forest-dependent species (cf. Lees and Peres 2008).
