A small, brightly colored inhabitant of thickets in woodlands and scrub. Feeds actively, snatching insects from leaves and twigs. It is passingly similar to the Northern Parula, but the parula has yellow-green on its back and the yellow below does not extend onto the belly as it does on Adelaide’s. Its song is series of rapidly given sweet notes that accelerate as the song progresses before sometimes slowing again towards the end. Call is a sweet “chick” with a slight squeaky quality.
