Almost all habitats on the planet are home to birds, from the lowest deserts to the highest mountains. Birds have proved to be excellent indicators of biodiversity or productivity as they are easily observed and are relatively well known compared to other animals. Although bird species are distributed across the globe, habitat destruction, fragmentation, and loss have adversely affected their survival and distribution. Therefore, this study is an attempt to prepare a baseline data on avifaunal diversity with their relative abundance and species richness in different habitats within Lewi Mountain Awi zone, Ethiopia from December 2018 to October 2020, including both the wet and dry seasons. The sampling sites were stratified based on land cover features, and transect count techniques were employed. The data were summarized per season and habitat type in the excel spreadsheet throughout the study period. In this study, one-way ANOVA was used to determine the effect of habitat type on species diversity and abundance. T-tests are also use to analyze bird populations among seasons. A total of 1591 individuals, 56 bird species belonging to 29 families and 12 orders were identified during the two seasons. The Wetland habitat had the highest species diversity index (H’ = 3) with high evenness index (J = 0.88) during the dry season followed by the open shrubs habitat (H’ = 2.97) with the highest evenness index (J = 0.95). The settlement had the lowest species diversity (H' = 2.17) and the lowest evenness index (J = 0.8) in the same season. During the wet season, disturbed forests recorded the highest Shannon-Weiner diversity index (H’ = 3.2) with the highest evenness (J = 0.92) followed by Wetland habitat (H’ = 2.97) with high evenness index (J = 0.87). During dry and wet seasons, the abundance of birds' species in different habitat types did not differ significantly (F = 1.91, p = 0.193, dƒ = 3) and (F = 1.579, p = 0.199, dƒ = 3), respectively. From all studied habitats, the overall mean abundance of bird species between dry and wet seasons was significantly different (F = 3642, P ≤ 0.001, dƒ = 1). In conclusion, settlement had the lowest species diversity and the lowest evenness index in the research area for the entire season. The habitats are important to the conservation of birds, so good habitat management is required, such as minimizing agricultural expansion and overgrazing, demarcating the forest habitats for wild species only, and creating awareness among local communities.
Many bird species depend on wetlands and the surrounding habitats. However, the status of these wetlands, as well as their biodiversity, is poorly understood and maintained. From January to February 2021, we assessed the compositions, relative abundances, and distributions of bird species throughout five wetland habitats in the East Gojjam zone. In each study site, systematic random sampling techniques were applied at a 4 km interval along the wetland habitats. Bray–Curtis cluster analysis was conducted using PAST software. During the study period, Simpson’s Index and Shannon–Wiener Index were also used to assess the diversity of bird species at various study sites. As a result, a total of 55 bird species from 20 families and 9 orders were identified. During the study period, 49 species were classified as least concern, two were critically endangered species, two were vulnerable species, two were endangered species, and one was an endemic species. During the study, overgrazing and agricultural expansion were identified as threats to biodiversity. To conserve the biological richness of these ecosystems, a wetland conservation strategy and a sustainable usage system are required.
Understanding local communities’ attitudes towards wildlife conservation is important for policymakers and conservationists in implementing sustainable wildlife conservation strategies. The present study was undertaken to assess local communities’ attitudes towards wildlife conservation and the types of human–wildlife conflict (HWC) in the Konta Special District (KSD). A total of 95 household respondents were randomly selected for questionnaire interviews from two study kebeles. In addition, focus group discussions (FGD) and personal observations were used to collect qualitative data. Descriptive statistics and the chi-square test were applied to analyze the data. Overall, 51.6% of the respondents reported both crop damage and livestock depredation as the main types of HWC. The respondents ranked baboons (95.8%) and monkeys (65.5%) as the principal wildlife responsible for property damage. Habitat loss (75.6%) was reported as the main threat to wildlife existence. A total of 91.6% of the respondents expressed a positive attitude towards wildlife conservation, and there was no statistically significant difference between study kebeles, sex, or education level of respondents. Guarding (75.8%) was identified as the dominant traditional method used to reduce damage. Development activities should not compromise wildlife conservation goals. Employing effective protection methods and providing alternative livelihoods such as ecotourism, beekeeping, and livestock fattening were recommended to ensure coexistence between humans and wildlife and to promote sustainable development in the KSD.

Birds are key indicators of environmental health, providing critical insight into habitat quality through changes in abundance and community structure. This study examined avian assemblages in two wetlands within the Lake Tana sub-basin: Yiganda, a relatively undisturbed site, and Chimba, which is subject to significant anthropogenic disturbance. Using a systematic random sampling approach, we conducted bird counts during both dry and wet seasons. A total of 6,432 individuals representing 95 species were recorded across both wetlands. Seasonal shifts in bird abundance differed between sites: Yiganda showed a smaller decline in abundance and diversity from the dry to wet season, suggesting greater ecological stability. In contrast, Chimba exhibited more pronounced seasonal fluctuations. Notably, significant differences in bird diversity were found between the two wetlands during the wet season, but not during the dry season. These findings underscore the importance of conserving minimally disturbed wetlands and highlight the potential for restoring degraded habitats such as Chimba to enhance regional avian biodiversity.

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 < 0.05. Moreover, in both wet and dry seasons, the Chemoga wetland ( < 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 ( > 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.
