Stripe-backed wren
species of bird
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.
Breeding
The stripe-backed wren has attracted considerable scientific attention because it is a good example of co-operative breeding. It lives in groups ranging from 2 to 10 adult birds. Of these, only one pair breeds, laying eggs at the beginning of the rainy season (May to September). However, all members of the group participate in defence of the territory, and in feeding the young both in the nest and after fledging. They therefore qualify as helpers at the nest.
The non-breeding members of the group are usually offspring or siblings of the current breeding parents. After one or two seasons, females normally leave their natal groups and join another nest as helpers, typically in a neighbouring territory. Males, however, usually remain at their natal nest and if they survive will inherit the position of breeding male (though under some circumstances they too disperse).
“Stripe-backed wren” enters the record as species of bird. Crown Archives preserves that source wording while asking what Stripe-backed, wren and species can confirm, complicate or overturn.
Why this record matters
“Stripe-backed wren” is worth following because a concise public description often conceals a longer documentary argument. Here, Stripe-backed, wren and species provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Oct 5, 2025. The linked authority identifier is Q2667961. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
