Abstract: Ecological investigation of species diversity and abundance of birds was conducted from August 2010 to March 2011 in Addis Ababa Bole International Airport. Transect count and point count methods were used to investigate the abundance of birds. Observation was conducted by periodically walking along the study area early in the morning and late in the afternoon. Different diversity indices and statistical methods (Chi-square test and correlation) were used to analyze data collected during the field survey. Movement patterns, seasonal and temporal bird distribution as well as birds strike records were investigated. A total of 74 bird species grouped under 13 orders and 31 families were recorded. August had the lowest species diversity (H’=3.71), species evenness (E=0.61) and species richness (41). The highest species diversity, evenness and richness were recorded in December (H’=4.06), January (E=0.74) and September (61), respectively. Variation in abundance of birds was statistically significant between seasons and months. Abundance score of uncommon bird species was high both during the wet and dry seasons using encounter rate. Appropriate management of bird attractant sites is very important to discourage birds from the airport.
