Résumé :	The Oued Righ valley, in the northeast of Algerian Sahara, contains numerous salty wetlands which constitute a wintry refuge for a great variety of waterfowl, particulary the Great Flamingo Phoenicopterus roseus. More than 32,000 individuals (adults and immature) were counted during the wintering season 2004-2005 in the eco complex. These birds seem to prefer spacious wetlands, remote from any disturbance such as Chotts Merouane Melghir and Tindla (Fig. 1) which alone accommodated more than 90% of the Greater Flamingos wintering in the valley. On the Chott Tindla, which is the most accessible, a study of diurnal activity showed that the feeding is the dominating activity (approximately 70%), with a rate slightly higher for immature than for adults. In decreasing order, the other activities are walking (12%), which is generally associated with search for food, sleeping (8%), preening (4%), flying was observed exclusively in December and antagonism activities only during the winter. At night, we observed a contingent similar to that during the day, which lets us suppose that these water birds roost at night in our chotts.
