OPEN ACCESS 1 cdp08indiagmail.com (corresponding author), 2 neosacongmail.com Abstract: An atempt has been made to understand the extent of ornithophony (vocalizaton of birds) in the soundscape of Anaikaty Hills. The study was limited to 13 hours of daylight from dawn to dusk (06.00–19.00 h) between January 2015 and October 2016. Six replicates of 5-minute bird call recordings were collected from each hour window in 24 recording spots of the study area. Each 5-minute recording was divided into 150 2-sec’ observaton units for the detailed analysis of the soundscape. A total of 78 recordings amountng to 390 minutes of acoustc data allowed a preliminary analysis of the ornithophony of the area. A total of 62 bird species were heard vocalizing during the study period and contributed 8,629 units. A total of 73.75 acoustc space was occupied by birds, among which the eight dominant species alone contributed to 63.65 of ornithophony. The remaining 26 of acoustc space was occupied by other biophonies (12.60), geophony (5.57), indistnct sounds (7.66), and anthropogenic noise (0.41). Passerines dominated the vocalizatons with 7,269 (84.24) and non-passerines with 1,360 (15.76) units. Birds vocalized in all 13 observaton windows, with a peak in the frst three hours of the day (06.00–09.00 h). Vocalizatons of non-passerines were prominent in the dusk hours (18.00–19.00 h). Keywords: Acoustc community, bird acoustcs, bird vocalizaton, diurnal singing, ornithophony, soundscape analysis. DOI: htps://doi.org/10.11609/jot.4948.11.12.14471-14483 Editor: V.V.
