Russet-naped Wren Campylorhynchus humilis

Large wren usually found in small groups, less often in pairs. Mainly found in thorn forest and dry scrubby habitats. Note boldly barred wings and tail and russet nape patch. At most only limited overlap with the formerly conspecific Rufous-backed Wren; in Russet-backed the barring and spotting on the upperparts is more prevalent, and whatever rufous coloration is present is generally not as bright. Often detected by its marvelous loud song, often given by multiple birds at once, which consists of various nasal and whistled notes, with some harsh elements mixed in.
