Abstract.

Diversity of nesting birds in southern Tunisia oases.

Southern Tunisia oases constitute one of the most important habitats for birds along the Black Sea-Mediterranean flyway. Many passerines and non-passerines species depend on this agroecosystem for feeding, resting, and nesting. However, little information is available about the diversity of birds using this agroecosystem during the breeding period. In this study, an extensive survey of birds was carried out between May and June 2021 in 699 plots within 53 oases. A total of 4894 birds belonging to 23 species, 15 families and 4 orders were recorded in the study area. The order with the highest species diversity recorded were Passeriformes (79% of species), Columbiformes (13%), Bucerotiformes (4%) and Galliformes (4%). The most abundant groups were Passeriformes (62% of birds), Columbiformes (34%), Bucerotiformes (3%) and Galliformes (1%). The most abundant species were Laughing DoveSpilopelia senegalensis (n= 894), Rufous-tailed Scrub RobinCercotrichas galactotes (n=874), Western Olivaceous Warbler Iduna opaca (n=874), Turtle Dove Streptopelia turtur (n=695), Common Blackbird Turdus merula (n=256) and Eurasian Hoopoe Upupa epops (n=211), which together accounted for 78% of all birds recorded in the study. The most frequently encountered species in the study were Laughing Dove (recorded at 76% of survey sites), Rufous-tailed Scrub Robin (71%), Western Olivaceous Warbler (69%) and Turtle Dove (51%). Of the 23 recorded species, 21 species are listed as Least Concern. These baseline data on species diversity and abundance will be useful for assessing and interpreting future population trends.
