This experimental study was carried out for a 60 days period in which, a total of 24 pigeon birds with suitable weight (80-100 g) were kept in Animal house with suitable environmental conditions viz, controlled temperature, humidity & light source to minimize any other stress. Out of twenty-four, eighteen birds were divided into three treatment groups (6 birds in each group). Whole experiment was run in triplicate manner in breeding season. One served as Control (Group 1) and remaining three were experimental groups including Road traffic noise (Group 2), Military noise (Group 3) & Human activities noise (Group 4). Noise was applied as recorded high intensity music (1125 Hz/ 90 dB) through speakers for 5-6 hrs. daily. Blood sampling was done after 20, 40 and 60 days by sacrificing treatment birds. Noise stress significantly (p
