The stripe-backed wren (Campylorhynchus nuchalis) is a bird found in the savannas of northern Colombia and central Venezuela. It lives in dry, riparian woodland, or farmlands, and is found at heights up to 800 m. Some of the calls of stripe-backed wrens show individual variations that are consistent from father to son. This is a potential example of the formation of a dialect in bird song. The distinctive family calls seem to be used to maintain social contact between members of the co-operatively breeding group.
