Plumbeous Antvireo Dysithamnus plumbeus

Chunky antbird with a slightly hooked bill and a short tail; larger-bodied than most antwrens. The male is slate gray with a black breast and white spotting on the wings. Males also have a concealed white patch on their back. The female is mostly olive-brown with pale wing bars and throat. Inhabits the understory of humid forests where it occasionally follows mixed-species flocks. The song is a loud series of descending melancholic whistles.
