Résultat principal :

L’effectif, estimé à 12 000 flamants, était réparti principalement dans la partie méridionale du lac où la nidification se déroulait et 4 000 individus environ se nourrissaient dans la partie septentrionale. Au Sud, on pouvait distinguer quatre noyaux comprenant chacun des effectifs de plus d’un millier d’oiseaux alignés sur des ilôts de végétation. Dans ces secteurs rectilignes, des flamants paradaient ou construisaient leurs nids. Certains couvaient. Toutefois, ces derniers (une trentaine) ne représentaient qu’un très faible pourcentage de l’effectif total présent. Tous ces faits nous conduisent à situer un début de reproduction initiée dans les premiers jours de juin 2015.

Le lac se distingue malheureusement des autres zones humides algériennes par sa pollution marquée provoquée par les rejets des villes et villages alentour et d’usines  situées en amont des oueds qui s’y déversent.


Lake Télamine in Algeria, a new breeding site of the Greater Flamingo Phoenicopterus roseus.

For a very long time, the Greater Flamingo Phoenicopterus roseus was deemed to be a wintering species in Algeria. It now breeds in a number of localities in the Hauts Plateaux and the Sahara. A new nesting site, Lake Télamine, located in northwest Algeria, has recently been discovered. This finding reflects the continuous increase in Greater Flamingo numbers in Algeria and underlines the important role of Algerian wetlands in the dynamics of the western Mediterranean metapopulation of the species.

An estimated number of 12 000 flamingos were present and were distributed mainly in the southern part of the lake where the nesting took place, and about 4 000 individuals were feeding in the northern part. In the South, we could distinguish four nuclei each comprising more than a thousand birds lined up on vegetation islets. In these straight sectors, flamingos were parading or building their nests. Some were brooding. However, these latter (about thirty) represented only a very small percentage of the total numbers of flamingoes present. All these facts lead us to situate a beginning of breeding initiated in early June 2015.

Passerine abundance and diversity in a polluted oasis habitat in south-eastern Tunisia

Alaya-Ltifi, L., & Selmi, S. (2014). Passerine abundance and diversity in a polluted oasis habitat in south-eastern Tunisia. European Journal of Wildlife Research, 60: 535–541. doi:10.1007/s10344-014-0817-0

Gabès region, in south-eastern Tunisia, is nowadays considered as one of the most remarkable pollution hotspots in the Mediterranean due to the emissions of the Gabès-Ghannouche factory complex of phosphate treatment. However, because of the lack of detailed studies, the impact of such pollution on the terrestrial wildlife inhabiting this area still remains unknown. In this work, we checked whether the proximity to Gabès-Ghannouche factory complex was associated with a decreased abundance of passerines breeding in the neighbouring oasis habitat. Overall, passerine abundance was found to decrease in the proximity of the factory complex, but this decrease was more pronounced in insectivorous species than in granivorous ones. The latter species seemed to be more dependent on vegetation structure. Moreover, we found that in the sites close to the factory complex, the studied passerine community was dominated by the Sparrow Passer domesticus × hispaniolensis, which seemed to be the less sensitive species to pollution. However, in the more distant sites, passerine abundance was more equitably distributed among species due to the increase in the densities of pollution-sensitive ones. Our findings give support to those reported in polluted European forest habitats and stress once again the usefulness of passerines as reliable biomonitors of polluted terrestrial environments.

Breeding performance of blue tits in relation to lead pollution and nest failure rates in Algeria

Brahmia, Z., Scheifler, R., Crini, N., Maas, S., Giraudoux, P., & Benyacoub, S. (2013). Breeding performance of blue tits (Cyanistes cæruleus ultramarinus) in relation to lead pollution and nest failure rates in rural, intermediate, and urban sites in Algeria. Environmental Pollution 174: 171-178.


The breeding parameters and the egg and nestling morphology of Cyanistes caeruleus populations from rural, intermediate, and urban sites in Algeria and the relationships of those variables with lead contamination were studied during three consecutive years. Breeding success was explained only by predation and vandalism rates. Predation was higher in the rural area, whereas vandalism was higher in the urban site. The other measured breeding parameters and egg characteristics were relatively insensitive to study site. The morphology of urban nestlings exhibited a trend toward smaller body size and mass compared to individuals from intermediate and rural sites. Although lead concentrations were higher in the tissues of urban birds than in intermediate and rural individuals, we did not detect a clear influence of this variable on nestling morphology. We conclude that urbanization influenced blue tit breeding parameters through predation and vandalism and nestling morphology through mechanisms other than lead pollution.


► Life history traits in relation to lead contamination were studied in blue tits from rural, industrial and urban sites.

► The study took place in Annaba, the fourth most populated city of Algeria, during 3 consecutive years.

► Breeding success depended on predation and vandalism, which were high in the rural and urban sites, respectively.

► Urban nestlings exhibited a trend toward smaller body size and mass, which was not explained by lead contamination.

► Urbanization influences breeding success and nestling morphology in blue tits through other mechanisms than lead pollution.
