Manjunath - hostel no:6, MANIT campus Bhopal Madhya Pradesh

whenever i go to the water cooler in my hostel to get drinking water, i see 2 or 3 sparrows there. Nearer to the cooler, there is some kind of hole in the wall where lot of electrical wires are located. In that hole i observe the nest and sounds of the little ones whenever i go there.There are 4 water coolers in the hostel and i see the same scene at 2 of them This is happening for the past 1 year, and i see them daily. In the hostel i have noticed 3 nests.
