We collected a database on wintering waterbirds in the Sebkhet of Aures wetlands complex (SAWC), based on surveys during the period 1978–2019 as well as on a bibliographic search of theses, dissertations, and other reports. The main data are from 12 Ramsar wetlands within the SAWC. We found 57 waterbird species from 9 orders and 14 families. The most abundant species were Greater Flamingo, Pied Avocet, Common Crane, and several anatidae. The Gareat El Taref wetland hosted the high- est waterbird diversity, with 31 species and a Shannon index H’ = 3.30. The lowest waterbird diversity was found in Chott Tinsilt (8 species, H’ = 1.56). 77% of the waterbird species were winter guests. Out of 12 biogeographical regions, species classified as Palearctic were the most common (41% of species). Out of six trophic categories, polyphagous species were the most common (44%). Among the 57 species, 21 are protected at a national level. According to the IUCN Red List, 48 species are of «least concern», whereas the Slender-billed Curlew is classified as «critically endangered» species; the White-headed Duck is «endangered»; three species are considered «vulnerable» (Marbled Teal, Common Pochard, Audouin’s Gull); and four species are considered «near threatened» (Northern Lapwing, Red Knot, Black-tailed Godwit, Eurasian Curlew). The collected data should be used as a basis for the conservation of key species and of sites of great ornithological value.
