One of
the educational theme at the Refuge, is that while predators are a key component in
our natural environment, our understanding of predators is skewed,
because we
receive most of our education about this environment through mainstream
media,
particularly from movies, and other forms of non-data-driven
descriptions
found in media. The goals of the MSM are financial success and market
share
through entertainment, which, when they succeed, may
be fun to watch, but may also encourage a
view of nature based on the exceptional rather the commonplace.
By way of example, we mention that one of our favorite “actors” was Bart the Bear, the enormously popular brown bear, who up until his death two years ago, was the most prominent member of Doug Seuss’s group of animal actors. In almost all of his starring roles, the immaculately-groomed Bart is mauling a hapless hiker-hunter-crash victim, as in "The Edge", or, just as unlikely, defending an unrelated, orphaned cub, as in "The Bear". (In real life, it’s not unusual for a sow grizzly to have to defend her cubs’ lives against the ever opportunistic and unsentimental boar who sired them.) This makes for entertaining cinema, but gives a decidedly distorted version of what is normal in the life of any given grizzly. Wendy and I have seen about 40 grizzlies in the wild, evenly distributed between areas that permit hunting (areas of Alaska, the Yukon, BC and Alberta), and those that don’t (Denali, Yoho, Banff, Glacier and Yellowstone National Parks). Bears in the former group usually ran off, while those in the latter generally ignored our presence. This may not seem like a big sample, but it’s reflected in the fact that there are about 2 or 3 attacks by Grizzlies per year in all of the western US, Canada and Alaska, most caused by unlucky factors such as alarming a sow with cubs, or unwittingly hiking near a grizzly bear’s food cache. In other words, assuming you are not Timothy Treadwell, pushing the envelope by seeking out and living among grizzlies in Katmai, you are far more likely to be killed by lightning, a bee sting or a serious fall in Grizzly country than to be the object of a grizzly attack. None of these latter incidents would make the news, and it’s pretty clear that victims of grizzly attacks, assuming they play no overt role in encouraging them, are nearly at the top of the “world’s unluckiest people” pyramid. As a footnote, every black bear I’ve seen in the Adirondacks has immediately run away, except for those at Marcy Dam, who are pretty well adjusted to hikers, can’t be hunted there, and have made a living out of cleverly relieving campers of their food caches. The point is, just as we read about jets only when they crash, we read about Grizzlies only when one of them assaults a human being, and for the average non-biologist or animal behaviorist, this becomes the store of “knowledge”, as well as the unsupported state of expectations. To say it one more time, the media won’t print, because we won’t read, any story that suggests that probably half of the 400,000 visitors to Denali National Park last year at some point saw a grizzly bear, and nothing of any note occurred, except some good photographs, and a few pilfered picnic baskets. That story won’t sell the news, and reminds one of the old George Carlin routine that the only news that we care about is essentially bad news, and the bloodier and more tragic the better. This deflating of the popular image of the grizzly as a ruthless predator who invariably attacks, is even more instructive in the case of wolves. Most “wolf attacks" involve wolf hybrids, pets who are too often owned by irresponsible people who shouldn’t own dogs, never mind a dog who has any percentage of wolf in them. By contrast, see the essay at our web site, for our very positive experiences with wolf hybrids, raised with care in a favorable environment: http://www.adirondackholiday.com/Cree012807BillW.html. Common sense suggests that when you combine the genes of a dog which displays a propensity to aggression with the strength and jaws of a wolf, and then encourage it to be aggressive, you’ll end up with a dangerous animal. Wolves in the wild are a whole different story. We are avid readers of L. David Mech, whose landmark studies of wolves in the wild have helped define the direction of wolf studies, progressing from the days when most studies were based on morphology, literally trying to interpret behavior through anatomy and function, through studying the behavior of captive packs of wolves, studies which were flawed because they took no account of the fact that captive wolves could not leave the pack, thereby limiting their options and altering their behavioral possibilities. Morphological studies were flawed by the fact that creatures change behavior to adapt to changing circumstances. Homo sapiens was anatomically described as a “frugivore” by Linnaeus. Frugivores are animals which evolved to eat fruit and seeds, but we were able to spread around the globe by learning to eat meat and other staples. On the other hand, while grizzly bears are clearly carnivores from an anatomical perspective, 90% of what they eat is roots, berries and other vegetable matter. In short , it can be misleading to predict behavior from anatomy alone. The concept of “alpha” wolves arose during the period when captive wolves were studied, but has, ironically enough in light of the phrase, been abandoned after the recognition that the vast majority of wild wolf packs are comprised of “Mom and Dad”, the pups of the year. the sexually immature but physically mature (in terms of size) pups of the previous year, and perhaps a straggler or two from the previous year. Wolves generally leave the pack upon attaining sexual maturity at about 2 years of age, and if they don’t, Mom and Dad kick them out, the main exceptions being areas where game is so plentiful that the breeding pair allow their offspring to begin breeding, which can lead to opportunistic, wandering wolves being accepted into the pack as mates, or replacements for deceased mates. While it is not unusual for wolves from territory-bounding rival packs, to be killed in territory infringement-type disputes, there is almost no fighting within the pack itself, because roles are clearly established early on through play and dominance. At the same time, there is a tremendous amount of “threat” behavior and posturing in relationships between wolves within the same pack, with the baring of teeth and growling, submission and groveling, etc. But the old notion that a healthy “alpha” male, for example, will be driven out by a more dominant outsider who takes over the pack, has been largely discredited. In fact, when one considers how all observers, regardless of disagreements on other points, cite the unswerving loyalty, affection, empathy (as reflected in “whimpering” behavior), special consideration by all adults within the pack for pups generally, and other family bonding traits, one is tempted to call wolves the real “family values” creatures, as they demonstrate in action what we too often only profess. At the same time, wolves are extremely intelligent and naturally develop individual personalities over a wide range of possible personalities. Mech
did much of his ground-breaking early studies of wolves on Isle Royal
National Park in Lake Superior, a 400 square mile island populated by
about 1,000 moose and about 20 wolves broken into two or three packs.
The numbers of moose fluctuate by factors such as tic infestation, hot
Summers, deep snow in Winter, availability of browse, and other factors
you'd expect. The wolves are affected by parvo virus, distemper, mange
and their success in hunting moose. Mech pioneered following wolf packs
in small aircraft on Isle Royal and collecting data about wolf-moose
interaction, which leads to a more accurate understanding of wolves in
the
wild. Among
the more surprising results revealed by the data, in areas
where
the wolves prey on moose, their success rate, in terms of how many
moose were
killed and consumed, was only about 10%
of moose who were approached, and this included calfs and extremely
shaky,
older animals. The emerging pattern
suggested that if the wolves couldn’t succeed in getting the moose to
run, the
hunt was over before it began, because wolves are reluctant to
approach a
mature, confident moose, head on, since an adult moose is about ten
times as massive as your average wolf. In turn, if the moose was
healthy and
in its
prime, it had no reason to feel vulnerable, and, almost comically,
pretty much
ignored the approach of the wolves. From our personal experience, we’ve
been
mildly threatened by a few of the hundreds of moose we’ve encountered
in the
wild (in each case a cow with calf, basically warning us from
approaching), but
I can’t recall ever having a moose run away as though it sensed danger
in our
presence. In areas where prey less formidable than moose are plentiful
(e.g,
deer, beaver, etc.), wolves tend to favor going after those prey. On
an island as small as Isle Royal, it is likely that the wolf packs go
through a process of testing the individual moose they encounter from
time-to-time to see how vulnerable they might be. The same moose who
confidently ignores the approach of the pack one year, may find
himself, five or ten years later, stumbling through Winter, beset by a
terrible infestation of tics, and lacking the confidence he'd flaunted
before the approaching pack in years past. Perhaps this time the pack
smelled puss in the moose's tracks, and felt more encouraged by the
moose's vulnerability. Since most wolves die before their fifth
birthday, with starvation being the main culprit, the pack's numbers
may turn over two or three times, before they finally take our aging
moose. What is interesting about all this, is that it paints a different picture of predator-prey relationships than the popular notion of ruthless, blood-thirsty predators going after hapless, helpless prey, and it undermines many of the arguments about predator control. I believe there are solid reasons why we view the predator-prey relationship, and more generally, the role of predators in nature, through this prism. If I can be forgiven a little amateur psychologizing, civilization is enabled to a certain extent, by the restraining and channeling of certain instincts within us, instincts, for lack of a better word, which encourage us to do pretty much what we want, or what we feel is in our immediate best interests. With some exceptions driven by extreme religious, political and cultural values, physical violence against another, is considered criminal, morally reprehensible, and basically “uncivilized”. In addition, because it strikes at the very heart of the victim’s existence, physical violence, is viewed in an extremely personal way. Small wonder that we are frightened, titillated and entertained, by cinema depictions of attacks on people by real and imagined creatures. What could be more negatively personal than a direct threat to your life? In nature, on the other hand, physical assaults are not only completely impersonal, but extremely practical, in the sense that they generally represent the attempt to capitalize on an opportunity for sustenance. At the same time, creatures in the wild routinely posture and pose to try to dissuade other creatures from attacking. I was somewhat amused when I went looking for mountain lions in Big Bend National Park by myself years ago, to receive advice from a Ranger, who suggested that, if a lion fails to run away (not an encouraging sign, since it probably means you're being sized up as a potential target), I should put down the camera, and pick up a large stick and attempt to appear larger than my actual size, in the hope of persuading the lion that an attack on me might result in injury for them. While I didn’t see any lions, I was amused because this is pretty much what many creatures do in the wild, if they feel cornered and unable to escape. Look large and forbidding, and hopefully dissuade attack. Some others feign death, for example the hognose snake, while still others feign injury. Wendy was once called to the scene of an injured mallard, who was just fine, except that he was trying to lead his “rescuers” away from the nest, as though they were predators. (It should be noted
that this entire discussion often takes place in front of the wolf
enclosure, while
Cree and Zeebie accommodate us by demonstrating some of the points we
are
making. For example, if Cree doesn’t recognize visitors, he sends
Zeebie into
the safety of the den he dug under one of his “doghouse” enclosures,
and then
paces in front of the den. If Zeebie approaches “big brother” Cree, and
nuzzles
or nips at his neck, Cree may regurgitate undigested food for the puppy
to eat.
If Zeebie fails to display the proper caution in any given situation,
Cree will
growl at him, and mouth him with his teeth, and give him a “what for”,
without
ever actually harming him. Finally, Cree, who at the time was five
times
Zeebie’s
weight, indulges Zeebie’s play overtures, letting the puppy pretend to
stalk
and attack him, chase his tail, etc, pretending to fight back, but
again
without using the power in those jaws to inflict real harm. The
discussion up
this point is generally a seg-way into talking about more advanced
hunters,
namely raptors, whose enclosures we now go to.) We are fascinated with keystone predators like wolves, bears and mountain lions. Perhaps this is partly because they’re large and impressive, often very majestic looking, and partly because we realize they can be threats to us. They are also mammals like us, with obvious, differing personalities like us, playful and easily entertained by the simplest simuli, and their reactions to us are less mysterious than those of say, reptiles or raptors. What is also interesting is that when we compare them to reptiles and raptors, they are not as efficient as predators. For starters, while the larger predators do at times execute ambushes, their prey are typically aware they are under attack, even if only briefly, which increases the danger to the predator that they may be intentionally or inadvertently injured by their prey. Birds of prey, particularly owls, on the other hand, depend more on stealth, employing quick, silent or hidden strikes, which frequently kill the prey before they are aware they’re in any danger. But, here again, with raptors, Hollywood gives us an edited, “improved” version of the way things are. All of us have seen movies which include the flight of a bald eagle. Classical music plays, majestic mountains form the back drop, and then the eagle screams, and we all sigh. The only problem is that eagles actually have a fairly ugly raucous scream, so the movie makers substitute the cry of the red-tailed hawk, which has a beautiful cry. |
