Within its range, the Kabyle nuthatch cannot be confused with any other bird. The closest nuthatch geographically is the Eurasian nuthatch (Sitta europaea) which inhabits Europe widely and some localities in the Moroccan Rif mountains;{{cite journal |last=Burnier |first=Eric |journal=Nos Oiseaux|title= Une nouvelle espèce de l'avifaune paléarctique: la Sittelle kabyle, Sitta ledanti|trans-title=A new species of Palearctic avifauna: the Kabyle Nuthatch, Sitta ledanti|date=December 1976|volume=33|issue=8|pages=337–340|language=fr}} this species is larger than the Algerian, has no black on the crown and has orange-buff (or white for some subspecies) {{birdgloss|underparts}} tending to orange around the rump. The Kabyle nuthatch strongly resembles the Corsican nuthatch (Sitta whiteheadi), but the black crown differs in the males; that of the Algerian species covers the front of the head, as opposed to the whole head in the Corsican nuthatch. The underparts are of a warmer pinkish buff in the Algerian species. It is phylogenetically very close to Krüper's nuthatch (Sitta krueperi), with the front of the crown dark in the male and the supercilium marked white, but Krüper's nuthatch has pale grey underparts and a large russet-brown pectoral patch.

The Algerian nuthatch was discovered in Algeria by Jean-Paul Ledant, a Belgian naturalist and ornithologist, on 5 October 1975. Identifying it as quite different from other nuthatches, he wrote to the Academy of Sciences to report his discovery. Working on a revision of Sittidae, they encouraged Ledant to return to the site. He tried several times during the winter, but the mountain was too snowy to allow exploration. Ledant was finally accompanied by Jacques Vielliard in mid-April 1976 to observe nesting, which actually occurred later in the year due to the massif range's difficult climatic conditions. They had to wait until July to observe feeding behaviour and a few fledglings, as well as to make recordings and call trials with songs of Corsican and Krüper nuthatches. Only a dozen pairs were observed, but on the 5–6 July, Vielliard killed a pair of adults that had finished feeding their chicks to be used as type specimens.{{cite journal|last=Balsac|first=Henri Heim de|title= Commentaires sur la découverte d'un élément imprévu de la faune paléarctique |language=fr|trans-title=Comments on the discovery of an unforeseen element of the Palearctic fauna|journal=Alauda |volume=44|issue=3|date=1976|pages=353–355|url=https://www.biodiversitylibrary.org/page/61349494|access-date=30 September 2024}}{{cite journal|last1=Dubois |first1=Alain |last2=Nemésio |first2=André |url=https://www.mapress.com/zt/article/view/zootaxa.1409.1.1|title=Does nomenclatural availability of nomina of new species or subspecies require the deposition of vouchers in collections?|journal=Zootaxa |volume= 1409|date=2007|pages=16|doi=10.11646/ZOOTAXA.1409.1.1}} Kept in the describer's house, these specimens (the holotype and paratype) were seriously damaged after 2005 by insects, and were finally given to the National Museum of Natural History, France in 2015.{{Cite journal |last=Vallotton|first=Laurent |date=2015 |url=https://www.researchgate.net/publication/297716482|title= The Altai Nuthatch: a missing link? |journal=9th International Meeting of Bird Curators|place= Darwin State Museum, Moscow |via=ResearchGate}}

The Algerian nuthatch was formally described in the journal Alauda by Jacques Vielliard in 1976 under its current name of Sitta ledanti. This discovery greatly surprised the ornithological world, as the bird seemed to come from a "lost world" that has withstood the test of time, the Babor Mountains. A species of bird endemic to the Mediterranean had not been discovered for nearly a century since the 1883 discovery of the Corsican nuthatch.

In December 1976, the Swiss ornithologist Eric Burnier announced in the journal Nos Oiseaux that he had discovered the species independently on June 20 of the same year, before learning from a July 28 article in Le Monde that he had been preceded in his discovery and that the species had just been named.{{cite journal|last=-JB|first= J.|title=Un oiseau inconnu découvert en Algérie |language=fr|trans-title=An unknown bird discovered in Algeria|journal=Le Monde|date=28 July 1976|url=https://www.lemonde.fr/archives/article/1976/07/28/un-oiseau-inconnu-decouvert-en-algerie_2951235_1819218.html|archive-url= https://web.archive.org/web/20190916023836/https://www.lemonde.fr/archives/article/1976/07/28/un-oiseau-inconnu-decouvert-en-algerie_2951235_1819218.html|access-date=30 September 2024|archive-date= 16 September 2019}} He published a few drawings and field notes, explaining that he had spotted birds that he had judged to have the characteristics of the Corsican nuthatch and Krüper's nuthatch by song and then approached them only a few meters away. The only nuthatch in the Maghreb then known being the Eurasian nuthatch, which occurs in some localities of the Moroccan Rif and Atlas Mountains about 900 km from the Babor Mountains, he knew he was dealing with a new species.

The Algerian nuthatch is placed in the subgenus Micrositta, described by the Russian ornithologist Sergei Buturlin in 1916,{{cite book | last=Matthysen | first=Erik | title=The Nuthatches | publisher=A & C Black | publication-place=London | year=2010 | isbn=978-1-4081-2870-1 | oclc=727646681 | page=}} and has no subspecies.{{cite web | title=Nuthatches, Wallcreeper, treecreepers, mockingbirds, starlings, oxpeckers – IOC World Bird List | website=IOC World Bird List – Version 11.2 | url=https://www.worldbirdnames.org/bow/nuthatch/ |archive-url=https://ghostarchive.org/archive/20220130/https://www.worldbirdnames.org/bow/nuthatch/ |archive-date=2022-01-30 |url-status=live| access-date=24 January 2022}}{{cbignore}} American ornithologist Charles Vaurie had grouped in 1957 the Corsican nuthatch, the red-breasted nuthatch (Sitta canadensis) and the Chinese nuthatch (Sitta villosa), which he considered to be very similar, in the "Sitta canadensis" group.{{cite journal|journal= American Museum Novitates|last= Vaurie|first= Charles|issue= 1854|year=1957|pages=1–26|title= Systematic notes on Palearctic birds. No. 29, The subfamilies Tichodromadinae and Sittinae|hdl= 2246/3596|url=https://digitallibrary.amnh.org/handle/2246/3596|issn=1937-352X|oclc=47720325}} In his 1976 description of the Algerian nuthatch, Vielliard devotes a portion of his paper to the possible relationships of the different species and their evolutionary history. He suggests that Vaurie stopped at a "superficial morphological similarity" to bring the Corsican nuthatch closer to the red-breasted nuthatch, and that the Corsican species should rather form with Krüper's nuthatch a group known as the "Mesogean nuthatches", "where Sitta ledanti providentially fits in". He considers it "tempting" to identify the fossil species Sitta senogalliensis (whose membership to the genus Sitta is discussed) described from the Upper Miocene in Italy as the ancestor of the Mesogean nuthatch group.

In 1998, Eric Pasquet studied the cytochrome b gene in the mitochondrial DNA of about ten nuthatch species, including the various species of the Sitta canadensis group,{{cite journal | title=Phylogeny of the nuthatches of the Sitta canadensis group and its evolutionary and biogeographic implications| first=Eric | last=Pasquet | name-list-style=amp | journal=The Ibis | volume=140 | issue=1 | pages= 150–156|date= January 1998| doi=10.1111/j.1474-919X.1998.tb04553.x }} which he defined as comprising six species, corresponding to those reported in the subgenus, Micrositta: S. canadensis, S. villosa, S. whiteheadi, S. yunnanensis, S. krueperi and S. ledanti. Pasquet concluded that the Corsican nuthatch is phylogenetically related to the Chinese nuthatch and the red-breasted nuthatch, these three species forming the sister group of a clade including Krüper's nuthatch and the Algerian nuthatch. The first three species would even be close enough to constitute subspecies, rejecting the "Mesogean" theory of Vielliard and thus confirming the conclusions of Charles Vaurie. For the sake of taxonomic stability, however, all retain their full species status.{{cite book |last1=Thibault |first1= Jean-Claude|last2=Seguin |first2= Jean-François|last3=Norris |first3= Ken|url=https://archive.wikiwix.com/cache/index2.php?url=http%3A%2F%2Fwww.developpement-durable.gouv.fr%2FIMG%2Fpdf%2FPNA_Sittelle_corse.pdf%2Findex.html#federation=archive.wikiwix.com|title= Taxonomic status and biogeographic origin |location=Regional Natural Park of Corsica|date=2000|page=52 }} In 2014, Eric Pasquet and colleagues published a phylogeny based on nuclear and mitochondrial DNA of 21 nuthatch species and confirmed the relationships of the 1998 study within the "Sitta canadensis group", adding the Yunnan nuthatch, which was found to be the most basal of the species.{{cite journal|doi=10.1007/s10336-014-1063-7|url=https://link.springer.com/article/10.1007/s10336-014-1063-7|title=Evolution within the nuthatches (Sittidae: Aves, Passeriformes): molecular phylogeny, biogeography, and ecological perspectives|journal=Journal of Ornithology|date=April 2014|author1=Eric Pasquet |author2=Keith F.

The conclusions of these studies are in agreement with the morphology of the species, the red-breasted nuthatch, Corsican nuthatch and Chinese nuthatch sharing as a derived character the entirely black crown only present in males, a unique trait among the nuthatches and related families. The second clade, which includes Krüper's and Algerian nuthatches, have the front of the crown black in males, with this sexually dimorphic trait absent in juveniles.

The simplified cladogram below is based on the phylogenetic analysis of Packert and colleagues (2014):

In 1976, the Swiss ornithologist Paul Géroudet suggested that the Mesogean nuthatches once inhabited a fairly continuous belt of conifers around the Mediterranean, which had become fragmented, leaving only a few hard-to-reach refuges where these different species were able to evolve in isolation.{{Cite journal |last=Géroudet |first=Paul|title= À propos de la Sittelle kabyle |trans-title=About the Kabyle Nuthatch|journal=Nos Oiseaux|date=December 1976|volume=33|issue=8|pages=340–342|language=fr}} In 1998, his phylogeny having been established, Pasquet concluded that the paleogeographic history of the group would be as follows: the divergence between the two main clades of the "Sitta canadensis group" appeared more than 5 million years ago, at the end of the Miocene, when the S. krueperi and S. ledanti clade settled in the Mediterranean basin at the time of the Messinian salinity crisis; the two species making up the clade diverged 1.75 million years ago. The other clade split into three, with populations leaving Asia from the east and giving rise to the North American red-breasted nuthatch, and then, about a million years ago, from the west, marking the separation between the Corsican and Chinese nuthatches.

It is a repetition of seven to twelve phrases lasting for two to four seconds. The bird may also produce a rapid trill in di-du-di-du-di-du, and when agitated, it emit a harsh and repeated chèèh comparable to the call of a jay.

The Algerian nuthatch's diet has not been extensively studied.{{cite journal |last1=Gatter|first1=Von Wulf |last2=Mattes |first2=Hermann |journal=Journal für Ornithologie|title= Zur Populationsgröße und Ökologie des neuentdeckten Kabylenkleibers Sitta ledanti Vielliard 1976|date=1979|volume=120|issue=4|pages=390–405|doi=10.1007/BF01642912 |bibcode=1979JOrn..120..390G |s2cid=46065939 }}{{cite journal |last1=Mayache |first1=MEA|last2=Temagoult |first2=L.|last3=Bara |first3= M.|last4=Moulaï |first4=R. |journal=Studia Universitatis "Vasile Goldiş", Seria Ştiinţele Vieţii|title= Diversity and dynamics of potential prey of the Algerian Nuthatch Sitta ledanti during the breeding season |date=10 November 2020 |volume=30|issue=3|pages=136–144|issn= 1584-2363}} It varies according to the season. In summer, it feeds mainly on insects (mainly caterpillars and beetles) and spiders that it finds by surveying the trunks and branches of oak trees. In winter, insects are scarce and the Algerian nuthatch feeds on coniferous seeds which provide a constant supply.{{cite book |last=Harrap |first=Simon |others=Illustrated by David Quinn |title=Tits, Nuthatches and Treecreepers |date=1996|editor=Christopher Helm |publisher=Helm|isbn=0-7136-3964-4}} They generally feed alone, but may form mixed feeding flocks outside the breeding season.File:Sitta ledanti - Karim Haddad - at nest.jpeg

The breeding season occurs from May to June in Tamentout and Mount Babor, earlier or later depending on weather conditions and food availability; at higher altitudes it may start later. In Taza National Park, the breeding season ends in late June. The nest is built in a tree hole, perhaps excavated by a great spotted woodpecker (Dendrocopos major), in a dead fir tree or in holes in an oak or cedar tree, and is usually placed between {{convert|4–15|m|ft|abbr=on}} from the ground. The bottom is lined with plant debris (wood chips, dead leaves) or animal material such as western barn owl (Tyto alba) feathers or wild boar (Sus scrofa) hair. While incubation is carried out by the female alone (the male does not have a brood patch), both parents feed the young. Clutches have three or four fledglings. After the breeding season, adults undergo a full post-nuptial moult and young undergo a partial post-nuptial moult.

The Algerian nuthatch is the only bird endemic to Algeria. It inhabits certain areas of Kabylia, where it has been recorded in five localities isolated from each other by deforested areas unsuitable for its survival.{{cite journal |last1=Moulaï|first1=R.|last2=Mayache|first2=Mayache|url=https://magornitho.org/2018/10/new-breeding-site-algerian-nuthatch/|title= A new breeding site for the Kabyle Nuthatch, Sitta ledanti|journal=Alauda |date=2018|volume=86|pages= 73–74}} It was first discovered on Mount Babor, only about {{Convert|20|km2|sqmi|abbr=on}} from the Mediterranean coast.

Smaller numbers were discovered in 1990 in two other localities near this park, in Tamentout and Djimla. In the spring of 2018, a new breeding site was discovered in Ghabet Ezzen, between the communes of Chahna and Oudjana in the Jijel province. On 24 September of the same year, two amateur ornithologists, Karim Haddad and Larbi Afoutni, went to the site; about twenty individuals were observed and photographed in the Lerabaa forest.{{cite web |url=https://www.ornithomedia.com/magazine/voyages/observation-sittelle-kabyle-dans-nouveau-secteur-septembre-2018-foret-lerabaa-algerie-02794/|title=Observation of the Kabyle nuthatch in a new site: the Lerabaa forest|website= Ornithomedia.com|date=22 October 2018|access-date=24 January 2022}}{{cite journal|last1=Haddad|first1=Karim|last2=Afoutni|first2=Larbi|url=https://www.researchgate.net/publication/346970647|title=The Kabyle nuthatch Sitta ledanti: new locality, distribution and habitat|journal= Ornithos 26-2|date=2019|pages=83–94 |via=ResearchGate|access-date=24 January 2022}} The bird could be present in other oak groves of Petite Kabylie, but has not been documented yet.{{cite book|last1=Isenmann |first1=Paul|last2=Moali |first2=Aïssa |title= Birds of Algeria|publisher= Society for Ornithological Studies of France|date=2000|page=336}}

The Algerian nuthatch lives in oak forests between {{convert|350|m|ft|abbr=on}} and {{convert|1,120|m|ft|abbr=on}} altitude and in mixed forests of oak, Italian maple (Acer opalus subsp. obtusatum), and mixed coniferous forests up to the {{convert|2,004|m|ft|abbr=on}} summit of Jebel Babor.{{cite journal |last1=van den Berg |first1=Arnoud B. |title=PhotoSpot 11.

At lower altitudes, such as Tamentout, forests are dominated by cork oak, and stand densities are lower than at higher altitudes (above {{convert|1,000|m|ft|abbr=on}}), where this species is replaced by deciduous oaks such as Algerian oak (Quercus canariensis) and Afares oak.{{cite journal|last1=Monticelli |first1=D. |last2=Legrand |first2=V. |title= Identification of Algerian Nuthatch|journal=Birding World |volume=22|issue=8|date=2009|pages=333–335}} A study conducted in Mount Babor between the summers of 1981 and 1982 showed that the factors apparently favourable to the Algerian nuthatch in this massif were "the diversity of tree species, the size (or age) of the trees and indirectly the climate at altitude".

When the Algerian nuthatch was discovered, ornithologists estimated that the species numbered only a dozen pairs and it was feared that "its rarity would attract collectors" and that the announcement of its discovery would cause its disappearance. The discovery in 1989 of the much larger population of the park of Taza shows that the species is less threatened than it seemed, and that its endemism is not limited to Babor Mountains.{{Cite journal |last1=Bellatrèche |first1=Mohamed |last2=Chalabi |first2=Bouzid |title=New data on the distribution area of the Kabyle nuthatch Sitta lendanti |journal=Alauda |date=1990|volume=58|issue=2|pages=95–97}} The current distribution of the Algerian nuthatch seems to be limited by that of the forests that support it, and the fragmentation of populations may indicate that the species was once more widespread, before deforestation isolated it in the small islands of greenery that it populates today. The Algerian nuthatch has a small population: its numbers may not exceed 1,000 individuals. The bird is placed in the category of species with 250–999 mature individuals, which corresponds to 350–1,500 individuals in all. Although there are no precise figures to confirm this, these numbers are considered to be declining due to the reduction in habitat that the species is experiencing. The Algerian nuthatch has been considered "endangered" by the International Union for Conservation of Nature since 1994.

The main threat to the Algerian nuthatch is the destruction of its habitat. Fires, in particular, are destroying the old mixed forests on the top of Mount Babor, which are being replaced by poorer vegetation dominated by cedars. Cattle grazing and illegal deforestation (Mount Babor and Tamentout) are another threat to the habitat, even in Taza National Park. The construction of a motor road in the 1970s, which led to soil erosion and an increased risk of fire, or the fight against terrorism in the region, which is a source of disturbance for the species. The Algerian nuthatch may have several predators during incubation, such as the weasel (Mustela nivalis), the garden dormouse (Eliomys quercinus) and the great spotted woodpecker.

The species is protected in Algeria as one of 32 species listed in Decree No. 83-509 of 20 August 1983 on protected non-domestic animal species.{{cite journal |last=Bendjedid |first=Chadli |url=https://cites.org/sites/default/files/eng/cop/14/inf/E14i-23.pdf|journal=Official Journal of the Algerian Republic|title= Decree No. 83-509 of 20 August 1983 relating to protected non-domestic animal species|date=20 August 1983}} The nuthatch was included in a 1980 petition by the BirdLife International requesting that the U.S. federal government add 60 foreign species to the federal endangered lists.{{cite journal |author=Department of the Interior - Fish and Wildlife Service, Endangered and Threatened Wildlife and Plants|url=https://www.govinfo.gov/content/pkg/FR-1995-01-12/pdf/95-832.pdf#page=1|title=Addition of 30 African Birds to List of Endangered and Threatened Wildlife|journal=Federal Register|volume=60|issue=8|date=12 January 1995|pages=2899–2905}} This request was published in the official gazette of the United States. The petition was published in the Federal Register the following year,{{cite journal |author=Department of the Interior - Fish and Wildlife Service, Endangered and Threatened Wildlife and Plants|url=https://archive.wikiwix.com/cache/index2.php?url=https%3A%2F%2Fecos.fws.gov%2Fdocs%2Ffederal_register%2Ffr538.pdf|title=Addition of 30 African Birds to List of Endangered and Threatened Wildlife|journal=Federal Register|volume=46|issue=91|date=12 May 1981|pages=26464–26469 }} but these species, including the Algerian nuthatch, were not added to the endangered species lists until 1995.

The largest population is found in a protected area, the Taza National Park. To safeguard the species, it is important about the size of the existing populations and their ecological preferences. However, protective measures have already been put forward, including habitat restoration or preservation through reforestation, planting of firewood outside of existing forests, and fire prevention. The Algerian nuthatch is a flagship species for the preservation of the Babor Mountains forest.{{cite book|title=Save the birds|date=1989|author1=Anthony W. Diamond |author2=Rudolf L.
