Parker et al. (1996) list the research priority for the Blue-and-gold Tanager is a “medium” level compared to other Neotropical birds. Slud (1964) indicates that the Blue-and-gold Tanager is a rare bird, difficult to find it in the wild, and thus little information is known. It is possible that the sporadic records near the Panama / Colombia border, including Darien and extreme northwestern Colombia represent isolated populations and perhaps independently evolving lineages. These populations may be of conservation concern, and ascertaining as much should be a research priority. Along these lines, molecular divergence between the two subspecies of B. arcaei has not been tested, and species limits within putative races and isolated eastern populations should be a moderately high research priority. Information such as sexual reproduction, molts, predation, and many aspects of its general life history are not known. The population of this species is declining, so it will continue to become difficult to study this species.
