Mountain Wren

The mountain wren (Troglodytes solstitialis) is a species of bird in the family Troglodytidae. It is found in the Andes of northwestern Argentina, Bolivia, Colombia, Ecuador, Peru, and western Venezuela. == Taxonomy and systematics == The mountain wren has at times been considered to include the Santa Marta wren (Troglodytes monticola), ochraceous wren (T. achraceus), rufous-browed wren (T. rufociliatus), and tepui wren (T. rufulus) as subspecies. The South American Classification Committee of the American Ornithological Society (SACC/AOS) considers the five of them to be a superspecies. The mountain wren has five subspecies: T. s. solitarius Todd (1912) T. s. solstitialis Sclater (1859) T. s. macrourus Berlepsch & Stolzmann (1902) T. s. frater Sharpe (1882) T. s. auricularis Cabanis (1883) == Description == The mountain wren is 10.5 to 11.5 cm (4.1 to 4.5 in) long and has a mean weight of 11.8 g (0.42 oz). The adult of the nominate subspecies has a rufous brown forehead and crown, a less reddish brown nape, shoulders, back, and rump, and a rufous brown tail with narrow black bars. The folded wings also appear barred. It has a buffy brown supercilium with a darker brown line behind the eye and warm buff cheeks.…
