Although the research priority is classified as Low for the Brassy-breasted Tanager by Parker et al. (1996), much more data is required to fully understand the behavior and identification of this species. Limited information is available on plumages of the Brassy-breasted Tanager, including detailed information on male and female differences, juvenile plumages, and seasonal molt. More information is also needed on size differentiation between male and female individuals. Unfortunately, the behavior and life history of this species is poorly understood, and additional research on the territoriality, sexual and social behaviors, response to predation, and reproduction is needed.
