Campylorhynchus fasciatus
The Fasciated Wren, *Campylorhynchus fasciatus*, is a striking and highly social member of the wren family (Troglodytidae) found along the arid Pacific coast of South America. Averaging around 18 cm (7 inches) in length and weighing 28-32 grams, its plumage is characterized by a distinctive, heavy barring pattern across its grayish-brown upperparts and creamy white underparts, extending down its flanks and belly. Key identification marks include its prominent broad white supercilium, a dark e...
This species thrives in arid and semi-arid scrub, dry deciduous forests, open woodlands, and often riparian zones within its range, typically found from sea level up to 1,500 meters (occasionally higher to 2,000m).
The Fasciated Wren is primarily insectivorous, consuming a wide array of insects and other arthropods, which it gleans and probes from vegetation and the ground.
Fasciated Wrens are highly social, typically living in stable family groups of 2-8 individuals that cooperatively defend a territory year-round. Daily activities revolve around active foraging, with birds probing crevices in bark, dense vegetation, and leaf litter for insects. Their territorial d...
The Fasciated Wren is a resident species, with its range strictly confined to western South America, exhibiting no migratory movements. Its distribution spans from extreme southwestern Ecuador, particularly in the coastal provinces of Guayas, El Oro, and Loja, southwards through the arid and semi...
Least Concern
- The Fasciated Wren is a cooperative breeder, meaning multiple individuals (often family members) help the primary breeding pair raise their young. - They are known for building multiple dome-shaped nests within their territory; some are used for breeding, while others serve as communal roosting...
