Sylviorthorhynchus desmurii
Des Murs's Wiretail (Sylviorthorhynchus desmurii) is a diminutive and enigmatic passerine, a true jewel of the temperate South American forests. Measuring a mere 13-14 cm in length, with a body weight of 7-10 grams, its most striking feature is its extraordinary tail, composed of elongated, stiff rachises that lack barbs, giving it a distinctive "wire-like" appearance. Its plumage is generally rufous-brown above, with a faintly streaked crown and nape, contrasting with buffy-white underparts....
Inhabits dense, tangled undergrowth and bamboo thickets (especially Chusquea species) within temperate forests, often near streams or damp areas, from sea level up to 1800 meters.
Feeds primarily on small arthropods, including insects (larvae and adults) and spiders, which it gleans meticulously from dense foliage, bark, and stems.
This highly secretive bird is primarily diurnal, spending most of its time actively foraging low in dense vegetation, often within thick bamboo stands, making it notoriously difficult to observe. It employs a gleaning foraging strategy, carefully probing leaves, stems, and mosses for small arthro...
