Abstract: Ecological investigation of Bird species diversity of the avifauna recorded during a survey of the Gudekote sloth bear Sanctuary, Bellary District, North Karnataka. The survey was carried out between March 2015 and April 2016. 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 were used to analyze data collected during the field survey. A total of 132 bird species and 50 families were recorded. Terrestrial habitat contributed much in terms of species composition (87%) than aquatic habitat (13%). Shannon's diversity index indicate that terrestrial habitat had higher species diversity (H’ = 3.9996) than aquatic habitat (H’ = 3.0717). The overall bird diversity in both terrestrial and aquatic was (H’=4.2669). Appropriate management of bird attractant sites is very important to discourage birds from the Gudekote sloth bear Sanctuary. A complete checklist of species recorded from the area is also given along with respective relative abundance levels recorded during the survey.
