The long-billed woodcreeper (Nasica longirostris) is a sub-oscine passerine bird in subfamily Dendrocolaptinae of the ovenbird family Furnariidae. It is found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Peru, and Venezuela. The long-billed woodcreeper is one of the largest woodcreepers, with a slim body, small head, long neck, long tail, and an exceptionally long, slightly decurved, bill. It is 34 to 36 cm (13 to 14 in) long and weighs 78 to 92 g (2.8 to 3.2 oz). The sexes are alike. The adult's crown, nape, and auricular area are blackish brown with whitish buff streaks. It has a white supercilium, throat, and foreneck. Its back, rump, wings, and tail are bright cinnamon-rufous to rufous-chestnut. The tips of its outermost primaries are dark brown. Its breast and sides are streaked black and white; the rest of its underparts are olive-buff with spots and bars. Its iris is yellowish brown, reddish brown, or dark brown. Its bill is ivory to light gray or yellowish gray, often with a dusky base to the mandible. Its legs and feet are gray to brown. Juvenile birds have paler underparts than adults, sometimes with faint barring on the belly, and with paler and less distinct streaks on the breast.
