dc.description.abstractBird calls have always been the choice of ornithologists to identify and study the birds. Main objective of agricultural ornithology is using the scientific information obtained on birds for their management. The present work was carried out to study the bioacoustic signalling of House Crow (Corvus splendens) and Red-wattled Lapwing (Vanellus indicus) during both the breeding and non-breeding periods at two locations of Punjab: Punjab Agricultural University, Ludhiana (Location I) and Ahmedgarh, Dist Sangrur (Location II). It was conducted for 14 months during the period of May 2018 to July 2019 in six study areas. Calls of both the species were recorded by using Recforge II mobile app and were then analysed in Raven Pro 1.5 software of Cornell University, Ithaca, New York. It was observed that correlation of recorded calls of both the species at different locations show the dissimilarity in the call patterns. Changes in the call frequency, amplitude, pitch etc. were observed during different call patterns. During the study period House Crow was observed to be vocally less active in breeding season. On the other hand Red-wattled Lapwing was found to be vocally more active during breeding period as compared to the non-breeding period. During the present study total 5 types of calls were observed in House Crow involving different activities while 6 types of different calls were found in Red-wattled Lapwing. Hence it is concluded that acoustic study of avian species plays an important role in studying the behaviour of species.en_US
