Abstract


This research was conducted on avian species in the vegetation cover of Federal College of Forestry Jos, Plateau State, North central Nigeria, in order to determine the effect of different habitat types on the abundance and diversity of birds, the influence of vegetation variables on the abundance and diversity of birds and to prepare a checklist of
birds that utilize the vegetation cover of the college. A total of 15 transects of 200m each were laid in the three habitat types for bird survey. The data collected was analyzed using R Console software version 3.2.2. One way
analysis of variance (ANOVA) was used to compare mean abundance of birds across habitat types and as well as vegetation variables. A total of 1215 individual birds belonging to 12 families across 56 species were recorded in the study during the study period. The abundance of bird species in relation to habitat types showed no significant difference (F27 = 1.158, Adjusted R2 = 0.01075, P = 0.3293) but was higher in riparian forest. The abundance of birds from the pooled data in relation to vegetation variables also showed no significant difference (F8 = 0.7926, Adjusted R2 = -0.09754, P = 0.6005) but number of trees and shrubs were important variables. Richness was higher in the riparian while diversity index was higher in farmland and the Riparian forest (H=3.0) followed by the human settlement (H=2.7). This suggest that matrix of human settlement with natural vegetation can serve as a refuge or repository for birds.
