The "Wolf Almanac" is a tremendous source, as it covers everything there is to know about all wolves. A particular part of the book I focused on was the chapter about wolf behavior and activities. The section covers the structure of a wolf pack, and mentions several examples of studied wolf packs in Alaska's Denali National Park. The section extensively covers the average size of a wolf pack as well as the different roles wolves have within the pack, and how those roles are communicated.The book is well illustrated by beautiful photos and sites notable wolf biologists such as John Theberge. It was very useful in my research and helped to give me a great preliminary understanding of wolf behavior.

This BBC documentary "Wolf Pack" follows the integration of Canadian wolves into Yellowstone after the extinction of Grey Wolves in North America. The documentary follows the largest wolf pack, the "Druid Peak Pack," in Yellowstone through a huge growth in the wolf population of the pack and of Yellowstone park. The film is detailed and well made, not only does is show the dynamics of the Druid pack but also Grey Wolves in general.

A study by David Mech and Michael Nelson about mating patterns in North American Gray Wolves. The study was conducted on radio tagged wolves in the Superior National Forest of Minnesota. It is commonly understood that Gray Wolves mate for life, most commonly with a member of the same pack and can produce as much offspring as a litter per year of their adult life. This article defies that pre-conceived notion, following a single male who interacts with multiple females while they are both in heat. The male is tracked meeting with both females at the same time over 19 times, always in areas far from the occupation of any other wolves or packs. It is interesting to see that, like humans, wolves have a tendency to stray from the common institution of a single mate for life.

This book is very much a wildlife handbook. It is short and succinct. The section that was beneficial to my research about pack structure held very little new information, but one thing stood out. A paragraph talked about the size of a wolf pack, and how it is limited because if the pack is too large wolves can become distant from each other emotionally. Without strong emotional closeness among all wolves in the pack, a pack does not function properly. This was very helpful as it answered an important question I have been thinking about: why don't wolves just run in large herds and maximize the amount of food that they can hunt. A very good resource if even for that small amount of information.

Of Wolves and Men gives an intricate account of the relationship between humans and wolves over the course of history. The book reports the image of "the wolf" through ancient mythology, and the impact of that mythology on humans interactions with wolves. I focused on a chapter that explains the different social hierarchy's of wolf packs, along with wolves social values in the pack. This book is an excellent resource for my work as it gives me a much needed bridge between my main course of study, wolves, and my secondary course of study, humans. Lopez writes elegantly and cleanly.

This VPR radio program visits the topic of emotion in animals. Virginia Morell is an animal researcher and author of the book "Animal Wise: The Thoughts and Emotions of Our Fellow Creatures." Morell studies the emotions of different animals and their means for communicating those emotions. The large topic of interest in this short VPR news special is about whether humans have a special connection with dogs. Morell's answer is yes, dogs and humans have a similar way of communicating with facial cues and body language which makes our two species somewhat appealing to one another. This helps my research a lot in that it brings out not only the similarities between K-9s and humans but also the mysterious draw of one animal to the other. Since the domesticated dog is so closely related to the wolf, it is true that wolves have similar body language, facial expression and social behavior tendencies. Morell speaks about her topic of expertise with great ease and it is fun to listen to because she is so smart.

A 1990 documentary filmed in the Sawtooth Mountains. Jim and Jamie Dutcher follow what comes to be called "The Saw Tooth Pack." The couple follows the pack in a close and detailed fashion, naming the wolves. The roles of different wolves and the class system of a large wolf pack are a big part of this documentary.
