Monkey Nest...!!

Have u ever seen Monkey's Nest ? Last week, I was waiting in Nizamuddin Railway Station to receive my wife, I got to see the interesting sight, Monkey's family sleeping together. I had seen several documentaries in Discovery and NatGeo channels, but none had shown about how monkey sleeps ?

I saw family of monkeys (2 adults and 2 kids) sleeping on Steel beams which supports the roof. It was so peculiar that two adults are hugging each other with its kids in between and whole family is sleeping.

Is it called "Monkey's Nest" ????????
