Unique, medium-sized antbird with a spectacular heavy and markedly upturned bill. Male is slate gray with a black throat, breast, and tail, and black dotted wings. Female is chestnut with a darker tail and buffy spotted wings. Rare, local, and hard to see, typically skulking in the dark understory of second growth and mature forest in foothills, often in areas with dense bamboo. Best found by voice; song a series of short notes accelerating “deeu-deee-dee-dee-eet-et.”
