An ecological survey of Laro-limicolae in Northeastern Algeria

We conducted an inventory and characterization of Laro-limicolae settlement at three Ramsar sites located in Eastern Numidia (Lake Tonga, Lake Oubeira and El Mellah lagoon) between 2014 and 2016. We identified 27 species belonging to six families, dominated by Scolopacidae (10 sp.) and Laridae (9 sp.) followed by Charadriidae (4 sp.), Recurvirostridae (2 sp.) and for Glareolidae and Haematopodidae families (1sp.) Inventoried species exhibited different phenological status: resident (26%), wintering (44%), migratory breeders (19%) and wintering/breeding (11%). Population analysis showed the presence of protected species such as black-tailed godwit and Northern lapwing. Bird counts showed monthly variations in total abundance and richness, peaking during winter. Highest numbers were recorded in January and lowest numbers in August. Analysis of diversity and equitability indices indicated that maximum values (H? = 3.01 and E = 0.94) were noted at El Mellah lagoon in November and at Lake Oubeira in June. Our study provides recent and unpublished data on a group of birds that are little- documented for North Africa, particularly for Algeria. Our findings open the way for further, more detailed work on the subject, and may serve to develop action plans for the management and conservation of these bird populations and their habitats.
