Northern chestnut-tailed antbird
The northern chestnut-tailed antbird is a species of bird in the family Thamnophilidae. It is found in the Amazon Rainforest in northeastern Peru and far eastern Ecuador.
The northern chestnut-tailed antbird was originally described by the American ornithologist John Zimmer in 1932 as a subspecies of the southern chestnut-tailed antbird with the trinomial name Myrmeciza hemimelaena castanea. A molecular phylogenetic study published in 2013 found that the genus Myrmeciza, as then defined, was polyphyletic. In the resulting rearrangement to create monophyletic genera the northern chestnut-tailed antbird and the southern chestnut-tailed antbird were moved to a newly erected genus Sciaphylax.
