Striped Woodcreeper Xiphorhynchus obsoletus

A medium-sized woodcreeper, widespread in the lowlands across most of Amazonia. Most obvious feature is the fairly straight, pale bill – however, it is not quite as perfectly straight as Straight-billed Woodcreeper (especially the upper mandible). Also note the buffy streaking on the head, back, and breast. Tends to be confined to riverine and varzea forest, usually in the lower to mid-levels, sometimes following a mixed-species flock. Perhaps most easily detected and identified by voice: listen for the rather harsh ascending trill
