This usually happens when you look for something specific in the wild and discover that you end up finding something even more interesting. I was looking for some Tortoise photographs but very soon found that the entire area is full with snakes having sunbath. They were scattered here & there and mostly single. But this herd was primarily located as a single big snake which turned out be 5 as the distance reduced. and due to their alertness it was just two clicks and soon 3 of them disappeared.
Hope you people like it.
