Taxonomy and systematics

The whiskered wren was at one time treated as conspecific with the moustached wren (Pheugopedius genibarbis). [3] It has eight subspecies: [2]

Description

The whiskered wren is 16 cm (6.3 in) long; a specimen from Venezuela weighed 29 g (1.0 oz). The nominate adult has a grayish-black crown, olivaceous gray nape, bright chestnut shoulders, back, and rump, and a reddish brown tail with dull black bars. It has a grayish white supercilium, a black line through the eye, blackish cheeks with a white line below and a black malar stripe below that. The chin and throat are off-white, the chest gray darkening to olivaceous gray on the belly, and the flanks reddish gray. The juvenile is duller than the adult with less prominent facial markings and a buffy throat. [4]

The other subspecies have small differences from the nominate. P. m. saltuensis has a grayer chest and less distinct bars on the tail. P. m. yanachae has a slate-gray crown. P. m. macrurus' tail is dingy brown. P. m. amaurogaster is much darker with a sooty brown crown and ochraceous tawny underparts. P. m. consobrinus has a buffy tinge to the supercilium and a buffy neck and chest. P. m. tachirensis is darker than consobrinus with a dusky olive crown and white throat. P. m. ruficaudatus has more buff on its face and no bars on the tail. [4]

Distribution and habitat

The subspecies of the whiskered wren are found thus: [4]

The whiskered wren inhabits dense undergrowth such as is found at the edge of humid forest and in regrowing clearings. It shuns the forest interior. In elevation it generally ranges between 1,200 and 2,400 m (3,900 and 7,900 ft) but can be found as high as 2,800 m (9,200 ft) and in Ecuador almost down to sea level. [4]

Behavior

Feeding

The whiskered wren forages in pairs as high as 10 to 12 m (33 to 39 ft) above ground. Its diet has not been described. [4]

Breeding

The whiskered wren appears to have a long breeding season; nest building has been observed from December to May. The nest is a large ball of roots and grass with a side entrance, usually placed in the fork of a small tree or in ferns. [4]

Vocalization

Both sexes of whiskered wren sing in duet, "a splendid series of loud gurgling whistles" . The call is "a deep throaty 'bong bong'" . [4]

Status

The IUCN has assessed the whiskered wren as being of Least Concern. [1] In much of its range it is quite common and it is found in several protected areas. [4]

The montane foliage-gleaner is a species of bird in the family Furnariidae. It is found in Bolivia, Colombia, Ecuador, Peru, and Venezuela.

Fairly common and generally widespread in canopy and borders of montane forest; the most frequently seen foliage-gleaner in many subtropical Andean forests. Relatively easy to watch, the Montane Foliage-gleaner forages actively, sometimes even acrobatically, at middle and upper tree levels, clambering along branches, often hanging upside down or moving out onto terminal twigs, pausing to inspect epiphytes and dead leaves. One or 2 regularly accompany many mixed flocks. Not very vocal, but foraging birds give an occasional sharp "peck" call; dawn song is a series of tyrannid-like, irregularly paced "pik" or "peck" notes.
