The Algerian nuthatch (Sitta ledanti) is a small passerine bird which is the only bird species endemic to Algeria, where it is also the only nuthatch. It was first discovered on October 5, 1975, at the Djebel Babor in the Petite Kabylie range in northern Algeria, by a team led by a young Belgian agronomist Jean-Pierre Ledant. The Algerian nuthatch is a resident bird of five areas of mountain forest in northeast Algeria, with the fifth breeding site just discovered in spring 2018. Its range is limited by the availability of woodland, and it occurs only above 1,000m, with the population density increasing with altitude.
