Campylorhynchus megalopterus
The Grey-barred Wren (*Campylorhynchus megalopterus*) is a striking and robust passerine, endemic to the high-elevation montane forests of central and southern Mexico. Averaging 17-19 cm in length and weighing 30-40 grams, it stands as one of the larger wren species, readily identified by its heavily barred grey-brown upperparts and tail, contrasted with whiter underparts that may display faint barring on the flanks. A prominent whitish supercilium above a dark eye-line provides a distinctive...
This species exclusively inhabits high-elevation pine, pine-oak, fir, and cloud forests, typically found between 2,000 and 4,000 meters above sea level, preferring dense undergrowth and epiphytic growth.
The diet of the Grey-barred Wren consists primarily of insects and other invertebrates (e.g., beetles, caterpillars, spiders), which they glean actively from tree bark, moss, and foliage.
Grey-barred Wrens are highly social, diurnal birds typically found in cohesive family groups of three to ten individuals, which cooperatively defend a territory year-round. Foraging involves active gleaning of insects and other invertebrates from tree bark, moss, lichens, and dense foliage, with ...
The Grey-barred Wren is entirely endemic to Mexico, where its distribution is restricted to the high-elevation montane forests. Its primary range encompasses the Trans-Mexican Volcanic Belt (Eje Volcánico Transversal) and extends south into the Sierra Madre del Sur. Specific states within its bre...
