Good for you for picking them out. Here is a bit closer view during breeding season:

This is from Wikipedia, credits to: Wildland at Russian Wikipedia, CC BY-SA 3.0. I have hundreds of my own photos, but not digital. Kodachrome era, long gone. One of these days I want to digitize the best of them, but have not yet done it.
The large beast is a mature male, maybe ~11 years old, the little one on top is a pup a month or so old, and the smaller one up front is a female anywhere between 5 to 20 years old. She looks as though she is still pregnant. All told, I spent about a thousand hours studying them during breeding season.
