Hello Abhishek, and welcome to TN.
Since a young boy I have always had a love of pigeons so your image immediately captured my attention. I used to raise Rollers which do sumersaults while inflight. I loved to watch them fly and do flip flops in mid air and then circle the neighborhood. I had a big problem with hawks swooping down and carring them off, so I eventually got rid of them.
I see you call this a Royal Pigeon, so I assume it is a particular species that lives in India. It's markings are very beautiful and the colors reminds me of what we call a Rock Pigeon. They are basically feral pigeons that live in most cities here in the US.
Thank you for sharing such an attractive photo.
