First data on bird species composition of Djebel Aïssa National Park, Southwestern Algeria

Algeria has a diverse bird fauna, yet data from arid and semi-arid regions are scarce. To fill this knowledge gap, we conducted a study on the composition and conservation status of bird species of Djebel Aïssa National Park in the Naama province of Southwestern Algeria between September 2021 and September 2023. We collected data by using progressive frequency sampling (PFS) and line transects, which allowed us to systematically assess bird species across different habitats within the park. We recorded 94 species of birds belonging to 11 orders and 27 families. Passeriformes was the most abundant order, comprising 16 families and 67 species. The bird species detected were predominantly sedentary (50%) or wintering (39%), and some were visiting (8%) or migratory (3%). Most species were insectivores (45%), followed by granivores/insectivores (24%), carnivores (13%), omnivores (7%), granivores (6%), and carnivores/insectivores (5%). Most bird species were classified as “Least Concern” by the IUCN Red List, two species were “Near Threatened”, and one was “Vulnerable”. In addition, 29 species are protected under Executive Fiat 12–235 of 24 May 2012. Our study provides a baseline for future monitoring efforts and a basis for the development and implementation of conservation strategies in Djebel Aïssa National Park and the surrounding regions.
