Locally fairly common, Carmiol’s Tanager occurs in humid foothill and lower subtropical forest. They seem to especially prefer wet valleys and densely-foliated stream edges. There, they travel in small groups through the understory and mid levels. They also join with other species in mixed flocks. They forage on invertebrates by hopping and rummaging through the foliage, though they also frequent fruiting trees. This dull tanager is indistinctive and easily confused with many other species. Note the short tail, olive color above and yellow-green below, yellow throat contrasting with the greener head, and thick black bill. Flocks are generally quite noisy, giving incessant, repeated churring calls.
