The grey-browed wren (Pheugopedius schulenbergi) is a small passerine bird in the wren family Troglodytidae. It is found in northern Peru north of the Río Marañón. It was formerly considered to be a subspecies of the plain-tailed wren.

Taxonomy

The grey-browed wren was formally described in 1985 by the American ornithologists Theodore A. Parker III and John P. O'Neill based on a specimen that had been collected at an altitude of 2,713 m (8,901 ft) in the Cordillera de Colán of the Amazonas region of northern Peru. They considered the specimen to be a subspecies of the plain-tailed wren and coined the trinomial name Thryothorus euophrys schulenbergi where the specific epithet was chosen to honour Thomas S. Schulenberg who had collected the holotype.[2] It is now treated as a separate species based on the distinctive vocalizations and some morphological differences.[3][4]

Description

A medium-sized wren, it is 16–16.5 cm (6.3–6.5 in) in length. The male is larger than the female, weighing 34–38 g (1.2–1.3 oz) and 29.5–34 g (1.04–1.20 oz), respectively. In coloration, it is mostly brown and grey with a black and white face.[5]

Distribution

The grey-browed wren inhabits the Andes in northern to central Peru, at elevations 1,800–3,500 m (5,900–11,500 ft) but more commonly at 2,200–3,200 m (7,200–10,500 ft). It is a resident species, with migration not reported.[5]

Behavior

It forages in pairs or small groups, only occasionally in mixed-species flocks. It likely consumes small invertebrates including beetles and caterpillars. The grey-browed wren forms groups of 2–7 birds, typically a pair and its offspring. Nests and eggs of this species have yet to be formally described.[5]
