Parker et al. (1996) lists the research priority for the Ruby-crowned Tanager as "low" compared to other Neotropical birds. More information is needed on their mating system and predators. Their possible partially migratory behavior could be important to understand, for they may be important seed dispersers across forest fragments in the highly disturbed Atlantic Forest (Galetti and Pizo 1996). However, at least for large fruits, they do not eat the fruit in a manner that would disperse the seed (Côrtes et al. 2009).
