Golden-Crowned Warbler

This small warbler stays low in the understory of tropical and subtropical forest from Mexico to South America, gleaning insects from leaves and often joining mixed-species foraging flocks. Its plain olive plumage and bright yellow crown stripe are easiest to see when it pauses on an exposed twig, and its thin, buzzy song helps locate it in dense vegetation. Forest edges and second growth are as productive as mature forest, and activity peaks in the cooler hours of early morning.
