Bar-bellied woodcreeper

The bar-bellied woodcreeper (Hylexetastes stresemanni) is a species of bird in the subfamily Dendrocolaptinae of the ovenbird family Furnariidae. It is found in Bolivia, Brazil, Colombia, Ecuador, and Peru.

The bar-bellied woodcreeper is one of the largest members of its subfamily. It is heavy-bodied, with a shortish tail and a short and massive bill. It is 28 to 30 cm (11 to 12 in) long. Males weigh 114 to 125 g (4.0 to 4.4 oz) and females about 100 g (3.5 oz). The sexes have the same plumage. Adults of the nominate subspecies have brown to olive-brown head, upper back, and wing coverts, with pale streaks on the forehead. Their face is plain but for paler lores. Their lower back, wings, and tail are rufous-chestnut with darker tips on the primaries. Their throat is whitish with heavy dark streaks, their upper breast olive with pale black-bordered streaks, their lower breast plain olive, and their belly and undertail coverts olive with thin blackish bars. Their iris is red-brown to bright brown, their bill dark reddish to reddish brown, and their legs and feet grayish green to dusky. Juveniles have a more rufous back than adults, a mix of streaks and bars on the throat and breast, and a more brownish bill.

The other two subspecies have somewhat subtle color differences from the nominate. H. s. insignis is more olivaceous on its upperparts, has no streaks on the forehead and no black on the breast streaks, has a pale moustacial stripe, and has weaker barring on the underparts. H. s. undulatus is larger than the nominate, has no forehead streaks, is slightly more olivaceous and less reddish on its underparts, and has bolder barring on its belly.
