Nature Documentary: In the Valley of the Wolves
Narrated by F. Murray Abraham
In 1995, the first gray wolves were transported from Alberta, Canada to Yellowstone National Park, to repopulate the sprawling landscape with the species, absent for more than 70 years. The following year, a second wave of wolves was brought to the park from British Columbia, Canada; five of them were released together, and they were named the Druid Peak pack.
Since the arrival of those first immigrants, wolves have thrived in Yellowstone — and none more dramatically than the Druids. The epic history of the Druids, one of more than a dozen packs now occupying the 2.2 million acres of Yellowstone, is documented in NATURE’s In the Valley of the Wolves, was produced and shot in High Definition by Emmy-award winning filmmaker Bob Landis. On the Web site for In the Valley of the Wolves, you’ll learn how the successful reintroduction of Yellowstone’s apex predator has changed the entire ecosystem of the park, and about the threats that these majestic animals continue to face on their road to recovery.
The gray wolf or grey wolf (Canis lupus) is a species of canid native to the wilderness and remote areas of North America, Eurasia, and North Africa. It is the largest member of its family, with males averaging 43–45 kg (95–99 lb), and females 36–38.5 kg (79–85 lb). It is similar in general appearance and proportions to a German shepherd, or sled dog, but has a larger head, narrower chest, longer legs, straighter tail and bigger paws. Its winter fur is long and bushy, and predominantly a mottled gray in colour, although nearly pure white, red, or brown to black also occur.
Within the genus Canis, the gray wolf represents a more specialised and progressive form than its smaller cousins (the coyote and golden jackal), as demonstrated by its morphological adaptations to hunting large prey, its more gregarious nature and its highly advanced expressive behavior. It is a social animal, travelling in nuclear families consisting of a mated pair, accompanied by the pair’s adult offspring. The gray wolf is typically an apex predator throughout its range, with only humans and tigers posing a serious threat to it. It feeds primarily on large ungulates, though it also eats smaller animals, livestock, carrion, and garbage.
The gray wolf is one of the world’s most well researched animals, with probably more books written about it than any other wildlife species. It has a long history of association with humans, having been despised and hunted in most agricultural communities due to its attacks on livestock, while conversely being respected by some Native American tribes. It is the sole ancestor of the dog, which was first domesticated in the Middle East. Although the fear of wolves is prevalent in many human societies, the majority of recorded attacks on people have been attributed to animals suffering from rabies. Non-rabid wolves have attacked and killed people, mainly children, but this is unusual, as wolves are relatively few, live away from people, and have been taught to fear humans by hunters and shepherds. Hunting and trapping has reduced the species’ range to about one third of its original range, though its still relatively widespread range and stable population means that the species is not threatened at a global level, and is therefore classified by the IUCN as Least Concern.

Study shows pre-existing capacity of wolves to learn from humans
Domestication of dogs may have been built on this predisposition
December 2013: Wolves can learn from observing humans and pack members where food is hidden and recognise when humans only pretend to hide food, reports a study for the first time in the open-access journal Frontiers in Psychology. These findings imply that when our ancestors started to domesticate dogs, they could have built on a pre-existing ability of wolves to learn from others, not necessarily pack members.
A paper published recently in the journal Science suggested that humans domesticated dogs about 18,000 ago, possibly from a European population of grey wolves that is now extinct. But it remains unknown how much the ability of dogs to communicate with people derives from pre-existing social skills of their wolf ancestors, rather than from novel traits that arose during domestication.
In a recent study, Friederike Range and Zsófia Virányi from the Messerli Research Institute at the University of Veterinary Medicine, Vienna, investigated if wolves and dogs could observe a familiar ‘demonstrator’ – a human or a specially trained dog – to learn where to look for food within a meadow. The subjects were 11 North American grey wolves and 14 mutts, all between 5 and 7 months old, born in captivity, bottle-fed, and hand-raised in packs at the Wolf Science Center of Game Park, Ernstbrunn, Austria.
The wolves and dogs were two to four times more likely to find the snack after watching a human or dog demonstrator hide it, implying they had learnt from the demonstration instead of only relying on their sense of smell. Moreover, they rarely looked for the food when the human demonstrator had only pretended to hide it.
The wolves were less likely to follow dog demonstrators to hidden food. This does not necessarily mean that they were not paying attention to dog demonstrators: on the contrary, the wolves may have been perceptive enough to notice that the demonstrator dogs did not find the food reward particularly tasty themselves, and so simply did not bother to look for it.
Wolf inbreeding could end world’s longest predator-prey study: here.
