“…The presence of large numbers of the two endangered species, the black scaup (Aythya nyroca) and the white-headed duck (Oxyura leucocephala), which nest in very few areas at the national level (Boumezbeur, 1993;Houhamdi and Samraoui, 2002;Metallaoui andHouhamdi, 2008, 2010;Aissaoui, 2009;Lazli et al, 2011aLazli et al, , 2011bChettibi et al, 2013) make these areas important sites for their conservation. Of particular note, we point out that most Algerian wetland complexes are frequented by 15 species of Anatidae (Chalabi and Belhadj, 1995;Mettallaoui and Houhamdi, 2010;Baaziz et al, 2011;Seddik et al, 2012;Boudraa et al, 2014;Elafri et al, 2017), which is similar to the number of species recorded at our sites. Besides the species richness, the studied sites harbored a large number of waterfowls, reaching a maximum number of 1,002 winter individuals.…”

Ecology, phenology and wintering behavior of Anatidae in the wetlands of Souk–Ahras (north–eastern Algeria)

Understanding the spatial and temporal niche of waterfowl is essential for effective management and conservation. To determine the ecology and phenology of Anatidae in North Africa, we carried out a 12–month study (2019–2020) in three wetlands that constitute a winter refuge for waterbirds in the Souk–Ahras region in north–east Algeria. We surveyed species richness, the seasonal pattern of the number of Anatidae, and their wintering diurnal behavior using regular counts and scans. We recorded thirteen species: six wintering species (Anas clypeata, Anas penelope, Anas strepera, Tadorna tadorna, Aythya ferina, and Anas crecca crecca) and three sedentary nesting species (Anas platyrhynchos, Oxyura leucocephala, and Aythya nyroca), the latter two having national and international protection status. The survey showed that the wintering behavior of all these species is dominated by sleep, which on average accounts for almost half of the total time (48.91 %). Our results indicate that the three wetlands host a complex waterfowl community that includes species of conservation concern and that these sites likely play an essential role in providing the essential resources for wintering.

“…Two methods are applied, an individual count when the group of birds is small, does not exceed 200 individuals and is less than 200 meters away) or by visual estimation in the opposite case (Lamotte and Bourliere, 1969;Blondel, 1975;Legendre and Legendre, 1979;Tamisier and Dehorter, 1999). The margin of error of this method is estimated among professionals between 05 and 10% (Houhamdi, 2002;Seddik et al, 2010Seddik et al, , 2012Boudraa et al, 2014). This Method Is The Most Commonly Used In Water bird Censuses (Aissaoui et al, 2011;Houhamdi and Samraoui, 2001, 2002, 2003Seddik et al, 2010;Houhamdi, 2008, 2010;Metallaoui et al, 2009;Bensaci et al, 2011).…”

The habitats and ecosystems of the Mediterranean Sea are of prime strategic interest both ecologically and economically. The Ferruginous duck, a species widely distributed in Africa, Europe and Asia, these numbers have experienced declines and changes in distribution in recent decades. The primary reasons for these declines are mainly due to habitat degradation and loss and hunting for local consumption .

“…Counting of the species across the sites was carried out systematically. Swamps less than 200 individuals clustered within a distance less than 200 m (close to the observation point) were enumerated individually whiles visual estimation was considered for the opposite (Girard et al, 1998;Seddik et al, 2010). Monthly averages of the species abundance were used for statistical analysis.…”

Variations in physico‐chemical parameters of water as abiotic factors affect the spatio‐temporal distributions of the organisms that live in it. The present study aims to determine the influence of physico‐chemical properties on Ardeidae spatio‐temporal variations in the wetland of Ramsar site 1018 in Benin. To reach this goal, transect enumeration techniques and stationary counts lasting 15–30 min were used to count Ardeidae species once a month at different sites such as Nokoué Lake, Sô River, Porto‐Novo Lagoon, Ouémé River and ancient Lagoons from January 2015 to December 2016. Water physico‐chemical parameters were measured at three stations per site during the bird counts. Five of the 12 species recorded monthly were significantly influenced (p < 0.05) by water physico‐chemical parameters. It was then revealed that pH influenced Ardeidae spatial variation. Such information is relevant to the management of Ramsar Site 1018, which hosts migratory waterbird species from Palearctic (Eurasia) every year.
