It is one cub of T-73! it was sitting under a tree where her mother was laying down. It was really great sighting day when I saw T-73 with her one cub first time. I was waiting for the second cub but suddenly mom and her cub stood up and disappeared from our eyes. It is very excited because I have been waiting to see these cubs since June 15, 2016. see https://www.ranthambhoreguides.com/blog/new-tiger-tiny-cubs-at-ranthambhore
