Description wikipedia

The spot-crowned woodcreeper (Lepidocolaptes affinis), is a passerine bird in the subfamily Dendrocolaptinae of the ovenbird family Furnariidae. it is found in Middle America from Mexico to Panama. The spot-crowned woodcreeper is 19 to 22 cm (7.5 to 8.7 in) long and weighs 28 to 38 g (0.99 to 1.3 oz). It is a slim, medium-sized woodcreeper with a slim, moderately decurved bill. The sexes have the same plumage. Adults of the nominate subspecies L. a. affinis have a dusky face and sides of the neck with a black malar stripe. Their crown and nape are dark brown with conspicuous buffy spots or diamonds that sometimes extend as thin streaks onto the upper back. Their back and wing coverts are plain brown, their rump rufous-cinnamon, and their wings and tail rufous-chestnut. Their flight feathers have brown edges and the primaries have dusky tips. Their underparts are olive-brown with wide black-edged buffy streaks beginning on the lowest part of the throat that fade on the flanks and undertail coverts. Their underwing coverts are ochraceous buff. Their iris is dark brown and their legs and feet lead-gray to dull green. Their bill is bluish pink, pale gray, yellowish, or dark brown; its base is often darker and the tip a pale silvery horn. Juveniles are darker overall than adults, with less conspicuous spots on the crown, less distinct borders on the underside streaks, and a shorter and darker bill. Subspecies L. a. lignicida is similar to the nominate but much paler overall. L. a. neglectus is browner (less olivaceous) than the nominate, with a deeper buff throat and wider and paler, almost whitish, streaking on its underparts. The spot-crowned woodcreeper is quite similar to the streak-headed woodcreeper (L. souleyetii) but is distuished by its spotted, not streaked, crown. In addition, their ranges only minimally overlap.
