	abstract = {<p>An attempt has been made to understand the extent of ornithophony (vocalization of birds) in the soundscape of Anaikatty Hills.\&nbsp; The study was limited to 13 hours of daylight from dawn to dusk (06.00\&ndash;19.00 h) between January 2015 and October 2016.\&nbsp; Six replicates of 5-minute bird call recordings were collected from each hour window in 24 recording spots of the study area.\&nbsp; Each 5-minute recording was divided into 150 \&lsquo;2-sec\&rsquo; observation units for the detailed analysis of the soundscape. A total of 78 recordings amounting to 390 minutes of acoustic data allowed a preliminary analysis of the ornithophony of the area.\&nbsp; A total of 62 bird species were heard vocalizing during the study period and contributed 8,629 units.\&nbsp; A total of 73.75\% acoustic space was occupied by birds, among which the eight dominant species alone contributed to 63.65\% of ornithophony.\&nbsp; The remaining 26\% of acoustic space was occupied by other biophonies (12.60\%), geophony (5.57\%), indistinct sounds (7.66\%), and anthropogenic noise (0.41\%).\&nbsp; Passerines dominated the vocalizations with 7,269 (84.24\%) and non-passerines with 1,360 (15.76\%) units.\&nbsp; Birds vocalized in all 13 observation windows, with a peak in the first three hours of the day (06.00\&ndash;09.00 h).\&nbsp; Vocalizations of non-passerines were prominent in the dusk hours (18.00\&ndash;19.00 h).</p>
