The Flame-faced Tanager, like most Tangara, is omnivorous and eats both insects and fruits. According to Naoki and Taopanta (2001), T. parzudakii spends 71% of foraging time looking for fruit only, 6% looking for insects only, 6% not consuming a suitable food item, and 18% doing some other activity. Out of 197 Flame-faced Tanager observations, 40% involved arthropods, and 59% involved fruits, 1% flower buds, and 1% nectar (Naoki 2007). Prefered fruits include Miconia (35%) and Cecropia (18%) (Naoki 2003). Most fruits are obtained through gleaning (54%), but probing and more acrobatic maneuvers such as hang-side (16%) and reach-down (10%) are also used. Foraging for arthropods occurs almost exclusively on moss-covered (80%) and partially moss-covered branches (15%). Individuals will take arthropods from within this thick moss or pull away pieces of moss (Naoki 2003). Attack maneuvers used to obtain these arthropods include hang-down (30%), reach-down (23%), pull/bite (17%), probe (13%), and glean (9%) (Naoki 2003). Isler and Isler (1987) report the contents of 8 stomachs and all contained vegetable matter, including both fruit and seeds. However, none contained arthropods.
