In the current study, we sought to learn more about how certain migratory birds, Gangetic dolphins, and other aquatic fauna in Bhagalpur, Bihar, India's Vikramshila Gangetic Dolphin Sanctuary (VGDS) responded behaviorally to the abrupt changes in the urban environment brought on by the COVID-19-induced lockdown at home and abroad. Birds are bio-indicators, and as important participants in many food chains, they are essential to preserving ecological balance. A COVID-19-like epidemic that resulted in the implementation of total lockdown throughout the nation and overseas in 2020 and 2021 had a tremendous effect on human and animal life. Due to the total lockdown, numerous changes in environmental factors, including the quality of the air, water, and soil, were seen. This resulted in bizarre and unusual behaviour in birds and other creatures.
In contrast to past years, the birds were exhibiting their longer stay in the sanctuary area. Gangetic Dolphin detectability was also noted to be much higher than on other days. After a decade or more, gharials were spotted in the years 2020 and 2021. All these unusual behavioural alterations observed in some migratory birds, Gangetic Dolphins, and other aquatic wildlife during and immediately following lockdown may be caused by sudden, unanticipated changes in the weather and climate, by fewer human intrusions, or by the complete ban on fishing activity brought on by the global lockdown. The COVID-19 lockout provided opportunity for an animal behaviour experiment. The sudden quietness of the area, the unexpected drop in human activity, and the low pollution levels undoubtedly startled the birds and other animals and caused them to exhibit some unusual behaviours that cannot be disregarded and should be the focus of further study.
