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. 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). If the current breeding male dies or is removed, the next oldest male in the group normally takes... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Stripe-backed Wren is recorded against all the birds logged in Barranquilla (101 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
