Waterbird diversity at the Sebkhet of Aures wetlands complex, North East Algeria. – 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 highest 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.
