Hilty (2003) described the foraging behavior of Tangara parzudakii as moving outward “quickly and systematically” along inner braches leaning “down first to one side then the other” eating small fruits and berries. The primary foraging strata is the canopy.
Courtship feeding of berries observed in February (Ridgely and Gaulin 1980, Hilty and Brown 1986).
Social and interspecific behavior
Flame-faced Tanagers are often located in pairs or in groups of 3 to 7 individuals. However, this species often joins mixed-species flocks (Restall et al. 2007), with other tanager species most often making up the rest of the mixed species flocks (Isler and Isler 1987, Fjeldså and Krabbe 1990). A study by Bohórquez (2003) in southwestern Colombia showed that there is usually only one individual representing the Flame-faced Tanager in a flock. On average, 7 other species were found in flocks that had a Flame-faced Tanager.
