Abstract

 

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 of
 104 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.

 

Key words: Home Range, Urban
Development, Avian Species, Agricultural intensification and Habitat
