Résumé :	An ecological study of the Northern Shoveler, Anas clypeata, was conducted during two consecutive wintering seasons (2013/2014 and 2014/2015) in Garaet HadjTahar, a wetland complex of Guerbes-Sanhadja, Northeast Algeria. This species winters steadily in sizeable numbers, reaching up to 1523 individuals in January. Individuals are distributed in small groups in areas with no vegetation in the middle of the water body. The diurnal activity budget is dominated by sleeping which represents almost half (49%) the total time budget. This is following by swimming (32%), feeding (10%), preening (5%) and finally flying (4%). The last two activities are carried out at the beginning and end of the rainy season. This study shows that the Garaet Hadj-Tahar serves as a diurnal roost for the species.
