Similar Species

Resembles the Band-backed Wren which can be identified by the buff underparts, longitudinal bars on the upper back. The Stripe-backed favors drier habitats.

Diet / Feeding

They mostly feed on insects.

Breeding / Nesting

Most breeding occurs between May and September during the rainy season when their main food, insects, are readily available.

They have a highly developed system of cooperative nesting that involves one principle pair and "helpers" (often previous offspring or siblings of the breeding pair). The group defends a territory and jointly raise the young produced by the dominant pair. Two up to 14 "helpers" have been recorded.
