|Campylorhynchus fasciatus||Order: Passeriformes||Family: Troglodytidae (Wrens)|
Found only in Peru and Ecuador, this fairly large wren is found mostly in arid and semi-arid landscapes such as thorny scrublands, though in Ecuador is is found in some more humid environments. It also occurs in citrus orchards and other areas that humans have heavily modified.
The Fasciated Wren is a cooperative breeder, groups of up to 8 individuals helping a dominant pair. Its nest is a dome with a side entrance, constructed of grass and lined with feathers. It is sited in several species of trees and cactus. It also frequently uses an old mud nest of the pale-legged hornero. It sings in duets or groups.
