Identificación

The streak-headed woodcreeper is 19 to 21 cm (7.5 to 8.3 in) long and weighs 23 to 31 g (0.81 to 1.1 oz). It is a slim, medium-sized woodcreeper with a longish, slender, decurved bill. The sexes have the same plumage. Adults of the nominate subspecies L. s. souleyetii have a face with thin whitish buff and dark brown streaks; the sides of the neck are more heavily streaked. They have a whitish buff supercilium and eyering. Their crown and nape are dark brown with bold whitish buff streaks that often extend onto the upper back. Their back and wing coverts are rufous-olive to cinnamon-brown. Their flight feathers, rump, and tail are cinnamon-rufous to rufous-chestnut. Their primaries have brownish edges and dusky tips. Their throat is whitish buff to pale cinnamon. Their underparts are grayish olive to buffy brown with black-edged whitish buff streaks. The streaks are wide on the breast and sides, those on the belly and flanks narrower, and those on the undertail coverts minimal. Their underwing coverts are ochraceous to pale cinnamon-buff. Their iris is pale brown or brown, their bill pale brown or horn with most of the mandible bluish-pink, and their legs and feet grayish olive-green. Juveniles are very similar to adults but with small scattered dusky spots instead of streaks on their underparts.<p>The other subspecies of the streak-headed woodcreeper differ from the nominate and each other thus:

It also locally occurs in mangrove and in arid scrublands. In elevation it reaches 1,500 m (4,900 ft) in Mexico, 1,850 m (6,100 ft) in northern Central America, 1,500 m (4,900 ft) in Costa Rica (though uncommon above 900 m (3,000 ft)), 1,500 m (4,900 ft) in Colombia, and 1,600 m (5,200 ft) in Venezuela.
