Black-tailed humble coin, also blacktail (Latin Oenanthe melanura) is a species of passerine birds from the flycatcher family. Found in desert areas in North Africa, the Middle East and the Arabian Peninsula. It is a sedentary bird throughout its range.
Described by the Dutch zoologist Konrad Jacob Temminck in 1824 under the name Saxicola melanura... In 1856, the French ornithologist Charles Lucien Bonaparte took the species as typical for describing the genus of humble mints (Cercomela). According to the results of molecular phylogenetic studies published in 2010, the genus Cercomela is polyphyletic, and the type species, the black-tailed modest coinage, belongs to the genus Kamenka (Oenanthe). A more detailed study published in 2012 confirmed earlier findings. To create monophyletic genera, the black-tailed humble coin was moved to Oenanthe.
