White-throated Kingfisher catching a bird

I observed this White-throated KingFisher catching a prey - a bird. I can't identify the bird' s species because of a very far distance (about 50 meters).
After the catch, KingFisher perched on the lorry metal railing, to kill the bird by banging it against the perch and have his breakfast. Suddenly a common myna landed near him , look like it wanted a bit of the meal.
