Simpkins Large Wolf Bust Statue

The hierarchy, led by the alpha male and female, affects all activity in the pack to some extent. In most larger packs there are two separate hierarchies in addition to an overbearing one: the first consists of the males, led by the alpha male, and the other consists of the females, led by the alpha female. In this situation, the alpha male was originally assumed to be the "top" alpha, but biologists have since concluded that alpha females can and do take control over entire packs. The male and female hierarchies are interdependent and are maintained constantly by aggressive and elaborate displays of dominance and submission.

After the alpha pair, there may also, especially in larger packs, be a beta wolf or wolves, a "second-in-command" to the alphas. Betas typically assume a more prominent role in assisting with the upbringing of the alpha pair's litter, often serving as surrogate mothers or fathers while the alpha pair is away. Beta wolves are the most likely to challenge their superiors for the role of the alpha, though some betas seem content with being second, and will sometimes even let lower ranking wolves leapfrog them for the position of alpha should circumstances necessitate such a happening, such as the death of the alpha. More ambitious beta wolves, however, will only wait so long before contending for alpha position unless they choose to disperse and create their own pack instead(Wikipedia.org).
