Pachyramphus validus
The crested becard is 17 to 18.5 cm (6.7 to 7.3 in) long. The species is sexually dimorphic. Though its crown is somewhat shaggy it does not have an obvious raised crest.

They have a smoky gray spot above the lores on an otherwise grayish face. Their throat is whitish gray and their underparts pale smoky grayish with a cinnamon tinge. Voice: The crested becard is not highly vocal. It sometimes makes an "unstructured series of extr./very high, sharp rolling and strident see notes". Its song has also been described as "a low, clear, vibrating, descending series of 6–8 dui whistles" and its call "a shrill tsree whistle".
