Lockdown and Bird's Behaviour

 Bird's Behaviour during Lockdown, Personal Experiences and Observations 


The Royal Government of Bhutan on August 11, 2020, announced its first Nationwide Lockdown following a report of a COVID-19 positive case in Gelephu. Since then, the nation came together to render their inescapable support to the government and frontline workers to combat the COVID-19 in the country. As part of uniformed personal started to support the nation’s effort to keep the COVID-19 at bay by helping the frontline workers to implement the lockdown protocols ushered by the government and the Ministry of Health.

During the patrolling of Gelephu-Sarpang highway and Dekiling gewog as part of COVID-19 the task force, several behaviours such as movement patterns, feeding patterns, and distress calls have been observed especially during the first three days. The incidences of nearly 3 to 5 different species of birds were observed during the first three days of the lockdown. It included migratory and other native birds found in the location.

When there was no human movement on the street, highway or in the village, a greater number of species were seen encroaching the human settlement for nutrition. The variety of species visiting particular areas for feeding has increased from day one to day three during the lockdown. For instances, during the third day of lockdown, birds such as Wreathed hornbill, great hornbill, and Black-napped Monarch has started to make their visit in farming yards just like any other starlings and mynas which are so common in this location. It is therefore deduced that birds find their space when there is less or no human movement. This is a positive impact of corona pandemic for birds.

Additionally, it was also observed that there were emotional disturbances in birds through the distress call they made during the last three days of lockdown. There was fewer songs, contact calls and begging calls but more of a fighting calls and alarm calls. It may be due to a greater number of species present, yet it also indicates the degree of emotional disturbances in urban birds.

Therefore, for the first three days of lockdown, it was imperative to see that even the birds demonstrating certain traits and behaviours. The indication of such traits could be due to the unusual limited human movement in the area due to lockdown where the avian circadian system has detected a certain change in the biological rhythms in the space.
