This study examined the avifauna diversity of Covenant University Ota South Western Nigeria. The study area was divided into three blocks based on their different land use types. A total of 30 counting stations was used, and10 stations per each study site.Counting bands of 50m radius was used for all the stations.Forty one bird species were recorded in the Developed Area, Sixty six (66) bird species in the Farmland and fifty (98) species encountered in the forest area. In all, a total of104 bird species belonging to 33 families and 13 orders were recorded,The Order Passeriformes had the highest frequency (56 %) of the entire number of birds recorded, while the dominant family was Pycnonotidae, comprising (9.2 %) of the total species One rare bird species, Grosbeak weaver and 3 species of the malimbe were recorded From the result of the relative abundance of bird species obtained Pied Crow has the highest of (0.74) followed by Cattle Egret (0.53) in the Developed Area, Black Headed Weaver has the highest (0.16) followed by Cattle Egret (0.14) in the Farm Land while Common Bulbul had the highest in the Fallow Area. The Developed Area had the highest relative abundance of (1.723), Fallow Area (0.474 and Farmland (0.437).From the result obtained on the bird species diversity index Fallow Area had the highest diversity index in both seasons of the 4.218 in the dry season and 3.893 in the wet season while Developed area had the lowest 3.298 and 2.6. |
