“…To gather reliable data, the researchers used a geospatial positioning system (GPS72hz to determine the location of the sampling area, field binoculars to determine the clear vision of bird species at a distance, a notebook to register a list of birds before entering to SPSS, and pen to write the checklist of birds), and bird guidebook was used during the study period [ 32 ]. A preliminary survey was conducted in December 2022 to acquaint the study area with the topography, vegetation cover, accessibility, and habitat types [ 33 – 35 ] and, moreover, to observe roosting and nesting sites for birds in the study area [ 28 ].…”

“…Ethiopia's bird checklist thus remains still far from completeness [ 27 ]. Both the continued survival of the species and the enticement of tourists depend on an in-depth comprehension of the diversity and abundance of birds [ 28 ]. However, little attention has been devoted to the species variety and distribution of the local avian fauna, particularly in Legedadi Legetafo and the surrounding farmlands.…”

Exploring avian species diversity and distribution patterns is vigorous for conservation efforts in biodiversity-rich countries such as Ethiopia. Compared to other species, birds are relatively well-known and easily observed, making them great markers of productivity or biodiversity. Although bird species are found all across the world, their survival and range have been negatively impacted by habitat loss, fragmentation, and destruction. Thus, the goal of this study is to provide baseline data on avifaunal diversity in the Northeast of Addis Ababa, including species richness, distribution, and relative abundance in various habitats conducted from January 2023 to September 2023 using a stratified sampling design into three habitat types: settlement, farmland, and abattoir. A fixed-width line transect sampling method was used at the farmland and settlement, and a point transect was employed at the abattoir site to collect the bird data. The data were compared using Mann–Whitney and Kruskal–Wallis statistical tests in both seasons and habitat types. A total of 42 bird species belonging to twenty-three families, and nine orders were recorded during the study period. Of these, blue-winged goose and wattled ibis are endemic to Ethiopia. Hooded vultures and White-backed vultures are critically endangered species. The mean abundance of bird species significantly varied in the three habitat types (χ2 = 13.6, df = 2, p=0.001). The abundance of bird species was nonsignificant difference between wet and dry seasons (U = −0.874, p=0.381). The highest diversity (H′ = 2.74) was recorded at settlement, and the lowest diversity index (H′ = 1.09) was recorded at the abattoir in the dry season. In the wet season, the highest diversity (H′ = 2.66) was recorded in the farmland, and the lowest (H′ = 1.08) was recorded at the abattoir. The highest evenness (J = 0.94 and J = 0.93) was recorded on the farmland in the wet and dry seasons, respectively. In the study area, urbanization is extremely impacting the environment and altering ecosystem services upon which human civilization depends. Most of the avian species observed in the study area are capable and tolerant of human-induced habitats in the city. Therefore, city planners must consider conserving urban bird species’ habitats and feeding sites.

Wetlands and their surrounding habitats are rich in avian communities. However, the desire for human needs has degraded these ecosystems. The current study was carried out in the Chemoga wetland and its associated human-modified landscapes in East Gojjam, Ethiopia, during both the dry and wet seasons from December 2020 to August 2021. The study aims to investigate the species composition and diversity of the bird community. A line transect sampling technique was used in the human-modified landscapes, whereas the total counting method was used to study the wetland habitat. PAST software and Microsoft Excel were used for data analysis. Using a paired diversity T-test, the effect of seasons and habitats on species richness and abundance was compared. In total, 3890 individuals, 76 species, 31 families, and 13 orders were recorded from the studied habitats. Our results showed that the Chemoga wetland with low human disturbance had a greater number of birds and abundance than the human-modified habitats at P < 0.05. Moreover, in both wet and dry seasons, the Chemoga wetland ( P < 0.05) shows significant difference in the abundance of avian species. But, in the human-modified habitat, there is no significant difference in the abundance of avian species ( P > 0.05). The majority of birds scored frequent and common on the ordinal scale in both habitats and seasons. This study confirms that the studied habitats are important for the conservation of birds. Conservation measures are thus required to limit disturbances and foster species survival in the area.
