Advisor: Gutama Jira (PhD) The present study was conducted from August 2019 to March 2020 to investigate avian species composition, relative abundance and distribution in Jorgo Wato Protected Forest (JWPF). The study area was divided into natural forest, plantation forest and mixed forest habitats based on the vegetation type’s cover and topography identified during the reconnaissance survey. Data were collected by using Stratified sampling method and it also employed for point count and line transects methods. The data were collected in the morning (6:30-10:00 a.m.) and late afternoon (3:30-6:00 p.m.).The species diversity of each habitat in the two seasons was analyzed using Shannon diversity Index (H’) and Species evenness was evaluated using Shannon-Wiener Evenness Index (E).Analysis of variance (ANOVA) was used to see the effect of habitat association of avian in a given season and mean species richness was seen by using Chi-square in terms of season. A total of50species of birds were identified during the whole study period. Out of 51 bird species 22 species were observed during dry season, 13 species during the wet season and 16 species in both dry and wet season. The Taxonomic analysis grouped 51 avian species belonging to 35 families and 16 orders. During the wet season, the highest species diversity was recorded in the Natural forest habitat (H’=2.59) followed by the mixed forest habitat (H’=2.45). Both during the wet and dry seasons, avian diversity was highest in Natural forest habitat (H’=3.25) followed by mixed forest habitat (H’=3.205). During the wet season, high species similarity was seen between Natural and mixed forest habitat (SI=0.42) followed by mixed and plantation forest habitat (SI=0.23).The lowest similarity was observed between natural and plantation forest habitats (SI=0.167). The mean abundance of species between habitats and seasons showed (F=3.263, p=0.002, df =2 and (F=31.617, df =1, p=0.005. p 0.05) significant difference in avian abundance. Hunting, grazing by livestock and illegal human activities were the main anthropogenic threats in the area. The study area harbors considerable birds that are threatened by interacting anthropogenic factors. To decrease the impact of anthropogenic activities on wildlife of the study area, community education and participation play principal role for sustainability of wildlife in Jorgo-Wato Protected Forest. Key words: Avian abundance, species composition, species similarity and richness.
