The northern chestnut-breasted wren (Cyphorhinus dichrous) is a species of passerine bird in the wren family Troglodytidae that is found in central Colombia, Ecuador and northern Peru. It was formerly considered as a subspecies of the chestnut-breasted wren (Cyphorhinus thoracicus) now renamed the southern chestnut-breasted wren.
The northern chestnut-breasted wren was formally described in 1879 by the English ornithologists Philip Sclater and Osbert Salvin based on a specimen collected near the town of Remedios in Colombia. They coined the binomial name Cyphorhinus dichrous where the specific epithet is from Ancient Greek meaning "two-coloured".[1] [2] [3] The northern chestnut-breasted wren was formerly considered as a subspecies of the chestnut-breasted wren (Cyphorhinus thoracicus) now renamed the southern chestnut-breasted wren. The species were split based on the significant vocal differences despite the minor difference in plumage color. The species in monotypic: no subspecies are recognised.[4]
