The greenish tyrannulet is a small tyrant flycatcher of the Atlantic Forest and nearby woodlands, often joining mixed-species flocks as it forages. It is notoriously tricky to identify among similar tyrannulets; voice and subtle facial and wingbar patterns are key. It forages actively in the canopy and edges, gleaning tiny insects from leaves and twigs.
