Despite widespread degradation of cerrado habitat, the population of Collared Crescentchest is believed to be relatively stable throughout its large range. The IUCN Red List assesses this species as one of Least Concern (BirdLife International 2013).
Effects of human activity on populations
Collared Crescentchest is vulnerable to habitat loss, which is affecting many cerrado species in central Brazil, although this species is not yet considered to be at risk.
Melanopareia is said to have 'very delicately flavored and palatable flesh' (Krabbe and Schulenberg 2003). It is unlikely that the thought of crescentchests as tasty morsels has an impact on their populations.
