Lesser Woodcreeper

Xiphorhynchus fuscus

Small22 gForest

The striped woodcreeper is a small, slim member of its genus, with a longish, slim, slightly decurved bill. The species is 15 to 18.5 cm (5.9 to 7.3 in) long and weighs 15.5 to 25 g (0.55 to 0.88 oz). The sexes have the same plumage. Adults of the nominate subspecies have a mostly dusky face with a wide creamy to yellowish buff supercilium and often a pale eyering. Their crown and nape are blackish brown with small yellowish buff to cinnamon spots on the crown. The spots become streaks on the nape and sides of the neck and weakly continue onto the upper back. Voice: The lesser woodcreeper's song is a "fast, sharp rattle, stuttered at end"; the nominate subspecies' song also stutters at the beginning. It has been put into words as "chit, chit, chit, chee-ee-ee-ee-ee-ee-ee, chit, chit-chit." Its calls include a "very high, sharp 'fieet fieet' " and "doubled 'peep, peesp' and single 'speel' or 'wik' ".

Small46 gForest

The olive-backed woodcreeper is 19.5 to 25 cm (7.7 to 9.8 in) long, males weigh 40 to 52 g (1.4 to 1.8 oz) and females 32 to 48 g (1.1 to 1.7 oz). It is a medium-sized member of genus Xiphorhynchus, with a slightly decurved bill. The sexes have the same plumage. Adults of the nominate subspecies X. t. triangularis have a finely streaked face with a buffy supercilium and eyering. Their crown and nape are blackish brown with pale buff elongated spots. Their back, wing coverts, and rump are bright olive to brownish olive. Their upper back has scattered buff streaks. Voice: The olive-backed woodcreeper appears to be less vocal than many others of its genus. Its song is "a series of hard notes that accelerates then slows, 'we we we-we-we-we-we-WE-WE-We-we-wa' ". It also has a fainter song, "a weak and somewhat nasal series that accelerates into a slow trill, 'quee, quee QUEE-que-que'e'e'e'e'.
