Until now, the Algerian Nuthatch (Sitta ledanti) is known only in four sites, namely the forests of Babor, Guerrouch, Tamentout and Djimla (see map below). All sites are close to each other but separated by unsuitable habitats, and are located in what’s known as ‘Petite Kabilie’ or Kabylie of the Babors, north-east Algeria…
The breeding pairs of the Algerian Nuthatch have been censused in the Guerrouch forest (Taza National Park, Jijel, Algeria). A decrease in numbers was assessed when comparing with data collected in the early 1990s. The main reason is the habitat degradation by human activities. First data were obtained by studying a nest located in a Zeen Oak. The clutch size was of 6 eggs. Incubation time was estimated to last 17 days and the nestling period likely to last 21 days. The breeding season stretched from April to early June. No evidence of second clutch.

Svensson, L. 2015. A new North African subspecies of Common Chaffinch Fringilla coelebs. Bulletin of the British Ornithologists’ Club 135: 69–76.
In this recent taxonomic paper, Lars Svensson described a new subspecies of Common Chaffinch from north Cyrenaica, Libya: Fringilla coelebs harterti subsp. nov. Until now, the birds breeding in this region were generally included in Fringilla coelebs africana.
A new subspecies of Common Chaffinch Fringilla coelebs in North Africa is described. It is restricted to northern Cyrenaica in north-east Libya. Differences from the other North African subspecies, F. c. africana and F. c. spodiogenys, are discussed, the main ones being that males invariably possess a prominent white patch on the central nape, a hint of a white post-ocular supercilium, a more yellowish tinge both above and below, stronger yellow fringes to the tertials and wing-coverts, and a less clean blue-grey head. Reasons for not recognising the subspecies F. c. koenigi are reconfirmed. There is some variation in size and in saturation of male plumage within the range of africana, making separation of koenigi untenable.

The Double-spurred Francolin Francolinus bicalcaratus ayesha is a critically endangered galliform subspecies in Morocco. To improve the viability of this threatened population, 300 captive-bred francolins were released into the Didactic Lot of the Royal Moroccan Federation of Hunting, and post-release monitoring was conducted. In this study, we used playback call counts to assess differences in habitat use and temporal variations in vocal activity of Double-spurred Francolins. The number of male calls per point count was significantly higher in the wooden matorral (WM) than in the non-wooden matorral (MT). The male responses per point count also increased depending on date, reaching a maximum in the first 10 days of March. The pattern was similar in the two habitats, although the maximum average call rates were significantly different [WM = 1.575 (95% CI: 1.394–1.780), MT = 0.481 (95% CI: 0.393–0.589)]. We suggest that call counts collected during this period could be used to index the annual change of the released population in that area. Further researches are, however, needed to (1) estimate the current population size of the released francolins and (2) characterize the habitats used within this protected area.
RAC/SPA-UNEP/MAP, 2014. Monitoring Mediterranean Lesser Crested Terns Thalasseus bengalensis emigratus. By Baccetti N. and Zenatello M. (Ed.), RAC.SPA, Tunis. 26p + Appendices. PDF
The Mediterranean Lesser Crested Terns, Thalasseus bengalensis emigratus, is a Mediterranean endemic seabird, potentially vulnerable to many sources of threat. In 2012, within the framework of the MedMPAnet Project, a study was conducted on this species in Libya, especially in Garah, a potential future MPA where the largest fraction of the seabird global population is concentrated.
Actions and methods are described to monitor the breeding population of the Mediterranean Lesser Crested Tern, which is currently confined to Libya. The aim is providing a tool which will allow a coherent and safe approach to a population of extremely high conservation value, which is potentially vulnerable to many sources of threat, not least monitoring itself.
Assessing changes in population size, distribution and breeding success is crucial for conservation. We attempted to gather recent experiences carried out under the RAC-SPA umbrella to produce a document available for further sharing, that may ensure a correct continuation of activities in the next future. The monitoring guide of the Mediterranean Lesser Crested Tern population is now available on-line at the RAC-SPA website.

Ecological analysis and patrimonial value of the breeding birds in the western Babors range in North-East Algeria.
The composition and patrimonial value of the breeding birds across the different available habitats were studied in the Western Babors range (North East Algeria). In this area, 90 point counts were carried out between 4 April and 31 July 2011. Among the 62 species recorded, 19 are of high patrimonial value (including 4 endemic species, the most famous being the Algerian Nuthatch Sitta ledanti). The species with the highest patrimonial value are linked to woodland habitats. Nevertheless, the oldest woodlands (Cedrus atlantica and Quercus afares) harbour the lowest number of species with high patrimonial value. The mean total species richness is higher in open areas than it is in woodlands (except in riparian forests).

Some considerations on the morphological features that differentiate Alectoris barbara barbata from A. b. barbara are exposed, and are also reported the results of a genetic investigation performed on historical specimens. Results showed a considerable genetic distance (0.06), certainly enough to consider it an ESU (Evolutionary Significant Unit), but most likely a separate species.

The new phylogenetic study was inconclusive regarding the split of the Maghreb Wheatear (Oenanthe halophila) from the Mourning Wheatear complex. However, it should be split by applying the integrative approach toward species delimitation as was applied in other cases including in the genus Oenanthe.
La nouvelle étude phylogénétique n’a pas été concluante en ce qui concerne l’élévation au rang d’espèce du Traquet halophileOenanthe halophila (c’est-à-dire le “split” entre ce taxon et le Traquet deuil Oenanthe lugens). Cependant, il devrait être “splité” en appliquant l’approche intégrative à la délimitation des espèces, comme cela a été appliqué dans d’autres cas, y compris dans le genre Oenanthe.
The morphologically inferred Oenanthe lugens complex comprises nine taxa of open-habitat chats which occur in rocky and/or mountainous areas adjacent to the Saharo-Sindian desert belt. It has traditionally been divided into the lugubris group of north-east Africa, the lugentoides group of the southern part of the Arabian Peninsula and the lugens group of North Africa and the Middle East. Previous molecular phylogenetic studies have shown that the O. lugens complex might not be monophyletic. However, it remained unclear how this result might have been affected by incomplete taxon sampling, as the lugentoides group and two out of three taxa of the lugubris group have not been analyzed so far. In this study, we present a phylogenetic hypothesis of the O. lugens complex based on two mitochondrial genes and one nuclear intron using, for the first time, a complete taxon sampling. The application of a multispecies coalescent approach allowed us to simultaneously estimate the sequence and timing of speciation events.
The O. lugens complex was consistently revealed as a polyphyletic assemblage and the traditionally recognized groups should be treated as at least three different species: O. lugens, Oenanthe lugubris, and Oenanthe lugentoides. While O. lugubris and O. lugentoides were revealed to be sister groups, O. lugens was found to be closely related to the species pair Oenanthe chrysopygia/Oenanthe xanthoprymna. The latter differ quite strongly in morphology and have traditionally not been associated with members of the lugens complex. We thus corroborate the results of previous studies, which demonstrated that morphology seems to be a poor predictor of phylogenetic relationships in Oenanthe. In contrast to the mtDNA markers analyzed, it was revealed that differences among taxa were not fixed in the nuclear intron. In the case of the taxa persica of the lugens group, an influence of introgression in autosomal markers cannot be excluded and deserves further study. The three species O. lugens, O. lugubris, and O. lugentoides and their associated taxa comprise a comparatively young radiation, which started to diversify in the Pliocene with major diversification events during the Pleistocene. The different taxa seem to have evolved during periods of increased aridity in isolation in rocky mountainous areas adjacent to hyper arid regions.
