CLOSED: Grouse ID from British Columbia

I recently saw this group of three grouse in Manning Provincial Park in British Columbia. Of course, the first thought would be that they are likely the same species, but I am not totally sure of that. In the second part of the video, I am presuming that is a ruffed grouse. Originally, I thought the two at the beginning were sooty? But now I wonder if they are ruffed also? The two at the beginning don't seem to have a mottled enough plumage to match pictures I see of different species. If anyone is able to help, it is greatly appreciated! Here is the video:

I have identified all the grouse as juvenile female sooty grouse and will take down the video shortly.
