Just to add a little color to the discussion, I thought I would post what I found about alpha males from Wikipedia:
From Simple English Wikipedia – the free encyclopedia that anyone can change
An alpha male is the top-ranking animal in a social group. Some animals live in a social structure where the more powerful male in the group is decided by either simple play-fights or even very aggressive battles. The current alpha male must defend his ranking from younger members. When he is too old or not strong enough to win, he loses his position in the group.
The result of this is that the alpha male usually has more opportunity to mate with the available females. This system evolved because strong males will produce young which have a better chance for survival.
- Some animal groups which may have alpha males
1.)The leader of a pack/herd/etc. 2.) The dominant male. 3.)The main source of population.
In wolf packs,the alpha male will mate with every female in his territory,whether they have mated already,or even from another den/territory.
