“…Higher number of bird species richness and abundance were observed during wet season than dry season, which in line with the reports of many authors who reported that bird species richness and abundance was higher during the wet season than during the dry season in different parts of Ethiopia [ 20 , 57 – 59 ]. However, the present study contradicts the findings of Yrgalem et al [ 12 ] and Amare and Girma [ 60 ] that birds species richness and abundance was the highest during the dry season. The maximum number of bird species and abundance during the wet season compared to the dry season may be due to the presence of high food sources, favorable weather conditions and occasionally high quality of nesting and breeding sites.…”

Background Dumpsites play key role in conservation of birds. A study was conducted to assess the diversity and abundance of birds in dumpsites of Afar region, Ethiopia from August, 2019 to March, 2020, covering both the wet and dry seasons. A total of nine dumpsites that contain domestic wastes found in different towns of Afar region were selected. Point count technique was employed to identify and count the birds. Shannon-Weiner diversity index was used to estimate species diversity and Two-way ANOVA was used to test birds’ species richness and abundance variation across dumpsites and seasons. Results A total of 48 bird species consisting of one endemic and 10 globally threatened species were recorded. Red-billed Quelea, Marabou Stork and Egyptian Vulture were the most abundant species. There was a significant difference in bird species richness and abundance among dumpsites (F = 8.44, df = 8, P < 0.05) and F = 15.507, df = 8, P < 0.05), respectively. Moreover, a significant difference in abundance was also observed between the two seasons (F = 19.339, df = 1, P < 0.05). The highest species diversity (H’ = 3.18) was observed during wet season in Abala and Afambo dumpsites and the highest species evenness (E = 0.86) was observed during dry season in Afdera. Conclusion Bird species diversity and abundance among dumpsites was high, and man-made disturbance are main threats for conservation of birds in the area. Therefore, conservation measures are needed to maintain survival of birds mainly the globally threatened species. Moreover, proper management of dumpsites is vital to support the waste dependent birds.

“…This could be due to the greater detectability of birds in open wetland habitats as opposed to places with dense forest, which results in poor visibility. This is consistent with the findings of Amare and Girma [ 47 ] and Gibru and Biru [ 48 ]. This study indicated that the wetlands support a large number of bird species, including two endemic species, the Thick-billed Raven ( Corves crassirostris ) and the Banded Barbet ( Lybius undatus ).…”

Wetlands are significant habitats for bird populations, and knowledge of the diversity and other ecological aspects of bird species contribute to the management of the ecosystem. The present study was based on comparative studies of the diversity and relative abundance of bird species in the two wetlands of southwest Ethiopia. The point count method was utilized in this study. For the data analysis, the Shannon–Weaver diversity index, independent sample t-test, and similarity index were employed. A total of 36 bird species under 11 orders and 24 families were identified. The species diversity and relative abundance were higher in both wetlands during the wet season. The Loga wetland had the higher diversity (H’ = 3.089), whereas the lowest species diversity (H’ = 2.643) was recorded in the wetland of Hurri. During the dry season, the Loga wetland (H’ = 2.738) and the Hurri habitat (H’ = 2.283) had higher and lower diversity, respectively. Seasonal variations in bird species diversity are not statistically significant (p > 0.05). Although the two wetlands support several water birds, they have received no conservation attention from concerned bodies. Further follow-up studies over a long period will help determine species-specific conservation measures for wetland-dependent birds.

“…The relative abundance of bird species during different seasons may be related to food availability, habitat conditions, and the species’ breeding season. Seasonal fluctuations in bird species abundance are caused by the unique seasonality of rainfall and seasonal variation in the amount of food supplies [ 55 , 56 ].…”

Birds are the most widespread vertebrate group, as they can be found in practically every type of habitat. However, lack of knowledge on bird ecology in Afrotropical highlands and bird habitat degradation are the main problems that is why this research was studied. The study was conducted in Awi zone, Amhara National Regional State with the objective of the diversity and relative abundance of bird species in the two habitat types of Dokima forest in Awi zone, Ethiopia. Between November 2018 and December 2020, the transect method was conducted in both dry and wet seasons. Using one-way ANOVA, the effect of seasons and habitats on species richness and abundance was investigated and compared. In both the dry and wet seasons, a total of 2233 individuals, 47 species belonging to 35 families, and 14 orders were recorded. The abundance of bird species was not statistically differed between habitat types in the dry season, but it was statistically significantly in the wet season. The mean abundance of bird species differed significantly between the dry and wet seasons. In the dry season, the forest habitat type had the highest species diversity index (H’ = 3.18) and the highest evenness (J = 0.94), while in the wet season, the forest habitat type had the highest evenness (J = 0.94). These habitats must be conserved in order to protect the birds that live in the area.
