Bats are nocturnal. They come out earlier before dusk and start flying. There is often a beautiful golden light in the sky then. Interesting fact that bats are the only mammals that can fly. Indian Flying foxes drink and cool themselves on warm days by flying low and briefly dipping their bodies into the water of ponds, lakes, or rivers. They then land in a nearby tree and lick the water from their fur. I took this photograph at Ramna park situated on heart of Dhaka city at Bangladesh.
