[2] The Duida woodcreeper is 17 to 19 cm (6.7 to 7.5 in) long; males weigh 24 to 25 g (0.85 to 0.88 oz).

Their breast and belly are grayish brown to olive-brown with bold, blackish-edged, pale buff to creamy white streaks.

Juveniles have darker upperparts than adults, a grayer crown with some spots, and whiter, somewhat reduced, streaks on the underparts.

[7] The Duida woodcreeper is found in the northwestern Amazon Basin of southern Venezuela, eastern Ecuador, northeastern Peru, and Brazil north of the Rio Solimões (upper Amazon River) and west of the Rio Negro.

[7] Worldwide taxonomic systems also include eastern Colombia in its range, but the South American Classification Committee of the American Ornithological Society lists it as hypothetical there, because all of the reports are undocumented sight records.

It hitches along branches, often on their underside, mostly in the forest's sub-canopy and canopy, occasionally in the middle levels, and rarely if ever in the understory.

[1] Because it is primarily a canopy specialist it is not well known; it is thought to be uncommon to fairly common throughout its range.
