Bull Elk Brother Bulls Square Paper Coaster

I have know idea if these two bulls are brothers, the caption just seems to fit. Once young male elk hit about two years old they leave the herd of cows and young elk they were born into and form bull herds that can be quite large, I have seen as many as seventy or eighty together but are usually around twenty or so animals. They are very friendly with each other until early fall when they separate and begin to get very aggressive and will have some brutal fights. Often they bugle to locate each other, when they come together sometimes one bull can intimidate the other and run him off without a battle.
