The southern nightingale-wren (Microcerculus marginatus), also known as the scaly-breasted wren, is a species of bird in the family Troglodytidae. It is found in Bolivia, Brazil, Colombia, Costa Rica, Ecuador, Panama, Peru, and Venezuela.
The southern nightingale-wren forms a species pair with the northern nightingale-wren (Microcerculus philomela) and was in the past considered conspecific with it. It is currently treated as a species in its own right by the International Ornithological Committee (IOC) and the Clements taxonomy, though under different English names.
The southern nightingale-wren has the six subspecies listed below. Subspecies M. m. luscinia is treated by some taxonomists as a separate species. The nominate subspecies M. m. marginatus is also sometimes considered a separate species or even two species divided by the Amazon River.

GBIF citizen-science records
It is estimated from how often the Scaly-breasted Wren is recorded against all the birds logged in Chagres National Park (281 verified sightings from 2019 to 2026), 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.
