Blue-necked Tanager is widely distributed and is fairly common across its range. Nonetheless, most aspects of its natural history are very poorly known. There is no information on such topics as age at first breeding, life span and survivorship, dispersal, population regulation, molts, territoriality and population density, sexual behavior, and responses to predators. There also is very little information regarding the reproductive biology of Blue-necked Tanager. Genetic information from individuals in the isolated parts of this species distribution could also clarify the nature of intraspecific variation in this species.
