Wood warblers are green on top, with a wide yellow supercilium. Their throat and breast are whitish-yellow, and the bottom of their body is white. Their long brown wings have yellow edges. Wood warblers are the biggest of warblers. They prefer to live in mixed forests of birches and spruces; they are seldom seen in gardens. They live in tree tops, often on the lower branches, where they anxiously jump while looking for food or hover in one spot above the branches and leaves. Their twittering is very characteristic.
