Spotted Woodcreeper

The spotted woodcreeper is 19 to 24 cm (7.5 to 9.4 in) long. Males weigh 40 to 54 g (1.4 to 1.9 oz) and females 40 to 46 g (1.4 to 1.6 oz). It is a medium-sized member of genus Xiphorhynchus, with a longish, slightly decurved and gradually tapering bill. The sexes have the same plumage. Adults of the nominate subspecies X. e. erythropygius have dusky lores, a buff supercilium and eyering, and dusky olive ear coverts with buff streaks. Their crown and nape are dark olive to brownish olive with small buff spots and a narrow dusky edge. Voice: The spotted woodcreeper is rather vocal. It mostly sings at dawn and dusk and less frequently during the day. Its song is "a series 4–6·5 seconds long of 2–5 (usually 3–4) long descending whistles, each at progressively lower pitch, and sometimes followed by 1–2 additional notes at same pitch".
