It is 13 to 16 cm (5.1 to 6.3 in) long and weighs 10.5 to 21 g (0.37 to 0.74 oz). The sexes are alike. The nominate subspecies G. s. spirurus has a grayish forehead, a rich brown to russet-brown crown and nape, light buff lores, a thin buff to buff-white supercilium, a buff eyering, sooty-brown auriculars, and a brown malar stripe. Voice: The wedge-billed woodcreeper sings mostly at dusk and dawn, though occasionally during the day as well. The subspecies in the pectoralis group of Central America into Colombia sing "a rapidly ascending, accelerating and somewhat slurred series of c. 25 bubbly notes...'twee-lee-lee-le-le-ee-ee-eeeeeé' ". It is also described as "weet-weet-WEEET-WEEET-weet-peet-peeet't't't't't't'teu".
