Descripción
This pioneering work is the first to document the aquatic avifauna community of the Wadi Djedi in the Ziban region in southeast of Algeria. We present results obtained through the monthly counts of waterbirds conducted from September 2013 to September 2016. On this wetland we recorded36 species of water birds representing 11 families. The Anatidae family was the most numerous, with 11 species. From among all the species, 18 were wintering species, nine were visitors, eight were sedentary breeding species (including the ruddy shelduck Tadorna furruginea and kentish pPlover Charadrius alexandrines ) and one species was migratory nesting (the white stork Ciconia ciconia) Two species (the teal marbled Marmaronetta angustirostris and ferruginous duck Aythya nyroca) are listed as Vulnerable on the IUCN Red List of endangered species.

Cobertura geográfica
The Ziban oasis is located in the east of Algeria, south of the Aurès Mountains (5° 44' 00" N, 35° 51' 00" E). The region is characterized by the arid Mediterranean climate. The average maximum temperature is 41.38 °C in August and the minimum temperature during January is 8.26 °C. Precipitation averaged about 128 mm over the last ten years (2004-2014). Wadi Djedi in the Ziban oasis is one of the largest Saharan rivers. It originates in the Saharan Atlas Mountains at an altitude of about 1400 m and it flows for about approximately 480 km from west to east

Datos del proyecto
North Africa has a great variety of wetlands that are wintering and stopover sites for several Palearctic migratory birds (Fishpool and Evans, 2001). Algeria contains a wide variety of wetlands that are major staging posts and wintering grounds for migrating birds (Stevenson et al., 1988). Waterbirds are an important component of the biotic community of aquatic ecosystems (Green and Elmberg, 2014). In the Algerian Sahara, waterbirds are relatively well known due to data collected by several ornithologists in the past (Heim de Balsac and Mayaud 1962; Ledant et al., 1981; Isenmann and Moali, 2000). These early works were based on observations recorded intermittently in a few wetlands. Since then, most ecological studies of the aquatic avifauna of the Saharan wetlands in the Oued Righ valley consist of ecological monitoring of wintering and breeding populations of rare and endangered species (Houhamdi et al., 2008; Nouidjem et al., 2012, 2014, 2015, 2016; Bouzegag et al., 2013; Bensaci et al., 2010, 2013, 2015). Few studies have been performed to determine the ecological importance and especially the ornithological value of Wadi Djedi. Here we present the preliminary data of our waterbird survey aiming to evaluate the status of species using this wetland.

| Descripción del área de estudio | The Ziban oasis is located in the east of Algeria, south of the Aurès Mountains (5° 44' 00" N, 35° 51' 00" E). The region is characterized by the arid Mediterranean climate. The average maximum temperature is 41.38 °C in August and the minimum temperature during January is 8.26 °C. Precipitation averaged about 128 mm over the last ten years (2004-2014). Wadi Djedi in the Ziban oasis is one of the largest Saharan rivers. It originates in the Saharan Atlas Mountains at an altitude of about 1400 m and it flows for about approximately 480 km from west to east (fig. 1). During the rainy season (winter), the river helps to raise the water level of Chott Melrhir (Ballais, 2010). The flora is dominated by Tamarix gallica, Atriplex halimus, Phragmites australis, Typha elephantina and Juncus maritimus. |
| Descripción del diseño | This study was undertaken through monthly bird counts from September 2013 to September 2016 using binoculars and a telescope KOWA (20×60). Surveys were conducted at three stations on the edges of the Wadi (fig. 2) to obtain consistent data. Individual counts were conducted when the numbers of birds present was small. When more than 200 birds were present, total numbers were estimated by dividing the flock into small equal blocks (50–200 birds according to flock size) and counting the number of blocks (Blondel, 1975). This latter method is that most commonly used in the winter counts of waterfowl (Lamotte and Bourlière, 1969). The bird community was sampled by performing counts of waterbirds from vantage points with unlimited distance (Blondel 1975; Legendre and Legendre, 1979). Three sampling points were chosen for the bird count. |
