A lively small inhabitant of pine woodlands, typically found fairly high in trees. It is similar to the Yellow-throated Warbler at first glance, but it has a bright yellow-olive forehead and lacks the Yellow-throated’s bold white eyebrow. Also distinctive is the dense, dark streaking on the sides of the chest and upper belly. Its song consists of several sweet notes on one pitch followed by several at a lower pitch; sometimes ending with a single note on original pitch. Call notes include one that is high and sharp and another that is sweet and slightly squeaky.
