I have received a very negative communication from someone regarding the accuracy of this photo explanation. I truly do love the idea, and now I have investigated more fully. Please see below for links and snippets of info and investigate further if you wish.
The alpha wolves decide when the pack will travel and hunt, and normally are the first to eat at a kill.
The pack works together as a family and the ranks are the jobs each pack member has. Ranks, whether high or low, are given or earned. You may request a rank, but the absolute of you getting that depends entirely upon the alpha.
AAahhhh, finally I come upon a snippet that tells us about the leader of the pack in travels and hunts. The order following, I have not found yet. Anyone who has a link and a snippet of further info would be appreciated if they would share.
Alphas lead travels and hunts. They feed first, and they exclude from feeding whom ever they choose. Maintaining alpha status requires controlling the behavior of pack mates. Occasionally a subordinate wolf is strong enough to take over the alpha position.
The alpha male and female are the oldest members of the pack and the ones with the most experience in hunting, defending territory, and other important activities.
