In Important Bird Areas in Costa Rica, about 2,500- 3,900 mature individuals of Blue-and-gold Tanagers are present, suggesting there are fewer than 10,000 mature individuals for the entire species. The overall population for immature and mature Blue-and-gold Tanagers has been estimated to be between 3,700- 15,000 individuals (Sánchez et al. 2009).
Parker et al. (1996) categorize Bangsia arcaei as uncommon relative to other Neotropical birds with a center of abundance in the Hill Tropical Zone. No information is available on the age at first breeding, life span, survivorship, parasitism, or population regulation.
