Very little is known about the diet of Turquoise Dacnis, but fruits, arthropods, and nectar all are likely important components of the diet (Hilty 2011). A male was observed actively gleaning insects from the canopy of Albizzia carbonaria trees, and a female was observed in a tanager flock aggregation at a fruiting Coussapoa sp. (Stiles et al. 1999). It also has been observed feeding on the floral nectar of Erythrina sp. and Calliandra sp. (Cortés Herrera et al. 2014). Unidentified fruit was found in stomach of a male in breeding condition (Hilty and Brown 1986).
