A small nuthatch endemic to a tiny area in northeastern Algeria with a sharply demarcated white eyebrow. Female similar to the male but slightly duller with a dark gray forehead. Somewhat similar to the closely related Corsican Nuthatch, but ranges do not overlap. Breeds in old-growth montane oak and mixed forests. Song is a loud, repeating, and rapid "Kyi kyi kyi kyi kyi kyi…" Call is a tit-like nazal "Dzuuee."
