Saturday 24th March, 6:25pm to 6:35pm, IISc, Main building. Landed to check the scavenger vulture, instead these noisy birds caught my attention. They were seated on two christmas trees. Now & then, they would take off, go around the main building or elsewhere and soon land back at one of these tall trees. And, they were quite noisy. The swish-swish of the wings as they take-off has to be heard. Crows gave them an hard time.
