Taxonomic status of the Atlas Long-legged Buzzard revisited

A new study showed that ‘Atlas Long-legged Buzzard’ is composed of individuals with admixed genomes of Long-legged Buzzard (rufinus) and Common Buzzard (buteo + vulpinus), but with closer relationship with the latter. The study thus suggested that cirtensis should be treated as a subspecies of Common Buzzard.

New breeding site of the endemic Algerian Nuthatch discovered last spring

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…

Status and breeding biology of the Algerian Nuthatch (Sitta ledanti) in the Guerrouch forest (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.

Hivernage de l’Erismature à tête blanche (Oxyura leucocephala) en Algérie

New data on the wintering of White-headed Ducks Oxyura leucocephala in Algeria

Abstract:

Winter census of the White-headed Duck in the wetlands where this species may occur allowed us to update the numbers present in winter in this country. A certain stability in winter numbers (around 1,000 individuals) was observed. Within the 240 censused sites, only some 20 harboured the species. The highest numbers were counted in the wetlands of Northeastern Algeria. In the west, increasing numbers were detected.

First breeding data on the Black-headed Gull Chroicocephalus ridibundus in Central West Morocco.

Abstract:

This study presents the first data on a breeding colony of the Black-headed Gull on islets of the Al Massira reservoir in central west Morocco from 2002 to 2008. Laying phenology, nesting site selection, clutch size, egg size and breeding success were investigated. These data provide new information at the southwestern limit of the species’ breeding area (32° N).

Breeding records of the Tree Sparrow Passer montanus in Algeria.

Abstract:

Until recently the Tree Sparrow was rather an accidental visitor to the country. New observations show that it is a resident breeder at least at Annaba in Northeastern Algeria.

Premières données sur le régime alimentaire des jeunes Pics de Levaillant (Picus vaillantii)

Henine-Maouche, A., Bougaham, A.F., Moulaï, R. & Nicolau-Guillaumet, P. 2017. Premières données sur le régime alimentaire des jeunes Pics de Levaillant Picus vaillantii. Alauda 85: 152-154.

Résumé:

Le suivi d’une nichée de Pic de Levaillant nous a apporté des résultats préliminaires qui méritent d’être approfondis. Les espèces de fourmis reconnues dans des sacs fécaux de ses jeunes, à la fois de petite taille (autour de 3 mm) et communément rassemblées en fourmilières de plusieurs milliers d’individus (CAGNIANT, 1997) sont, et de loin, les plus présentes sur ses zones de chasse dans les Babors comme elles le sont dans d’autres localités en Algérie. Le régime alimentaire de ce pic, comme son très proche parent, le Pic vert, pratique à l’évidence une myrmécophagie presque exclusive et Le choix des captures à l’attention de ses poussins, peut être qualifiée d’opportuniste.

First data on the diet of young Levaillant’s Woodpecker Picus levaillantii

Abstract:

At the study site, the fragments analysis of preys species found in fecal bags of Picus vaillantii, enabled us to say that Levaillant’s Woodpecker is myrmecophagy (99,93%) with a clear preference for the Tetramorium biskrensis ants (87,03%). The other species are weakly represented such Aphaenogaster testaceopilosa (3,81%) and Pheidole pallidula (2,96%). However the terrestrial preys, with a 3mm size, are the most appreciated by this woodpecker (92,34%). The results obtained with SORENSEN index (24,71%) and IVLEV index reveal that the preys consumed by P. vaillantii appear dissimilar enough with the environment preys and there’s little common species between the food mode and the preys availability. On other hand, there is a some similar between preys ants found in fecal bag and those from environment (SORENSEN index equivalent 61,11%). We can conclude that Levaillant’s woodpecker is selective in food search.
