This study was carried out in Lake Hawassa, Tikur wuha riverine habitat and Cheleleka wetland from August 2017 to February 2018. The study aims to investigate species composition, seasonal abundance and distribution of birds. Systematic random sampling techniques at an interval of 3 km were used to select sampling blocks. T-test and one way ANOVA were applied for analysis of the effect of season on the composition and abundance of species. The result showed a total of 103 avian species record belonging to 47 families and 14 orders during the wet and dry seasons. Of the species recorded, (71) bird species (68.93%) were residents, 29 Palaearctic migrants (28.16%) and 3 Intra-African migrants (2.91 %). The overall species composition of birds during the wet and dry seasons was not significantly different, but there was a significant difference within the study sites. There was no significant seasonal difference in the abundance of birds in Lake Hawassa and the riverine habitat. However, dry season had an effect on the avian abundance in Cheleleka wetland. Distributions of bird species were variable in the study areas. The results imply the need to conserve the avifauna of the whole study sites through the conservation of their habitats.

“…Tanzania has reserved about 40% of its land as protected areas [15]; these are distributed throughout the country and are largely located adjacent to rural communities. The majority of these rural communities depend on crops and livestock for their livelihoods; thus, a considerable number of people have settled around buffer zones surrounding protected areas where they believe that the land is fertile and there is sufficient grazing land [9,16,17]. Kideghesho et al [11] showed that there was a 52% increase in livestock from 175,680 to 266,624 from 1990 to 2011, respectively within areas adjacent to the western Serengeti National Park.…”

Agriculture is one of the factors contributing to the global depletion of natural resources. Human activities such as overgrazing, deforestation, bush fires, mining, urbanization and cultivation as well as climate change have aggravated the ability of bird species to disperse into new habitat. This study investigated how agriculture altered the bird community in the Serengeti National Park. This park is structured along a rainfall gradient with highest rainfall in agricultural land northwest of the Serengeti National Park and lowest rainfall on the treeless plains in the southeast of Serengeti National Park. With respect to trophic level in agriculture there was a greater proportional decrease of species (compared to savanna) at the predator trophic level (vertebrate feeders) than at the insectivore and herbivore trophic levels. Therefore, higher feeding levels were less able to tolerate change in habitat structure due to agriculture than species at lower feeding levels.
