Breeding ecology of the northern shoveller ( Spatula clypeata) in Tiffech Lake (Souk Ahras, Northeastern Algeria)
Abstract The breeding behavior of Northern Shoveler ( Spatula clypeata ) was studied from January 2019 to March 2021 in Tiffech lake, an artificial wetland, in Souk Ahras Province, Northeastern Algeria. On this ecosystem, egg-laying occurred from earlier January to mid-March. In this study, there wa...
