My Cougar Encounter

There are those moments in one’s life when time stops and moments become hours. So it was while trail running in the Wellsville mountains of N. Utah

Deep in the forest shadows materialized a form- a coyote! Well, that was the initial thinking. I stopped for closer inspection and began talking in a soft, welcoming tone so as not to frighten away my favorite song dog.
The animal form persisted- no frenzied running up the steep slope just beyond. Interesting.
I walked toward the figure to find the fright distance and for closer encounter. Eight steps in crunchy leaves and the animal began to move. Wow! A long tail emerges. The canine face transforms to feline. MOUNTAIN LION!!!

After 50+ years of trapesing through wild, rugged country in the western U.S., dream becomes reality- that of seeing this shadow being in real form.

Mesmerized, I continue a cautious approach. The cat holds its ground. Our distance closes to 50 yards when it begins a leisurely retreat. I continue singing praises to its magnificence. At one point I find myself emitting “Here Kitty, Kitty, Kitty” to which fortunately it doesn’t respond.

A large tom with striking colors- its lithe, fluid, soundless movement- poetry in motion, a marvel of artistic expression. It stops frequently, looking back to lock eyes with wonderment- perhaps its first close encounter with this strange being.

Eventually it gains the steep slope and picks its way upward. Occasional sunburst accents the rich tawny gold and well-muscled body. Eyes strain to follow its progress, fading into the dream it once was.

Cougars are solitary animals, making them a rare sight for humans. They usually hunt alone and at night, ambushing their prey from behind. Typically, cougars kill their prey with a bite to the lower neck. After making a kill, a cougar often will take the carcass to the base of a tree and cover it with dirt, leaves or snow, saving it to eat later.

Their main prey is deer, so cougars are often found close by. They can live up to 12 years in the wild but have lived up to 25 years in captivity.

Only 20 people in North America have been killed by cougars during the past 125 years, including six in California and 8 in Canada. No deaths have ever been reported in Utah. It is far less likely than dying from snake bites, avalanches, lightning strikes, hypothermia, or bee stings, or just about any other means. Children are particularly vulnerable when alone.

If approached by one, intimidation by intense eye contact, loud shouting, and any other actions to appear larger and more menacing is warranted.

Jack’s Urban Deer

As I look out my front window, 7 mule deer are cavorting, feeding, with some lying down for a mid-day siesta. With the final week of the regular season deer hunt winding down, some have taken sanctuary from the nimrods to join the urban herd.

For our 30 years in Smithfield canyon, deer have been regulars, disappearing for the most part from mid-May to mid-June to give birth, as do the bucks, perhaps somewhat embarrassed with strange bumps forming on their crowns.
Spotted fawns begin adorning our lawn in mid-July. With enough speed to outrun all but the fastest predator’s, mom drops her guard a bit. Bucks begin parading their new, fully formed head gear.

As fall and winter approach, the neighborhood herd grows, with a few dozen hanging out when winter finally sets in. Their snow trails through the yard become conspicuous, further defined with sprinkles of fecal material. Out back the steep hillside across Summit Creek becomes a winter playground as small groups run repeatedly up and down and around. Apparently, their abundant stores of energy allow them to break winter’s lethargy. This is generally not the case for deer in the wilds where every calorie is conserved for winter hardships as snow deepens and temperatures plunge.

We’ve witnessed a few humorous behaviors during our 3 decades of observation. Deer are very curious which occasionally works against their best interests. We had an especially aggressive rooster who became our “feathered” watchdog. A small deer herd passing through the front yard noticed the stocky cock guarding the front door and decided on closer inspection. The lead deer approached stretching his neck and tender nose to get a closer whiff. Old roaster rooster gave her a welcoming sharp jab to the nose which sent the herd bounding off.
On another occasion, our tomcat found itself taking refuge under the trampoline as 4 deer approached from a patch of forest. The cat’s movement piqued the deer’s curiosity. They surrounded the trampoline, bent down on front knees with noses poked underneath for a close-up. Poor tom was terrified- to be munched by a deer- what a horrible end!

Of course, we realize that not everyone is enamored with deer in their space. Deer can be a nuisance causing damage to landscapes and gardens. With proper fencing and plant selection, this can be managed. A greater concern is safety, vehicle-deer collisions. Here again, with proper signage, this can be minimized. I’ve experienced close encounters on my bike, so always go slow when deer appear near or on the roadway.
An excellent resource for landscaping is found at wildlife.utah.gov/habitat/deer-browse.php Blending a variety of native and ornamental plants into a home landscape can create a highly attractive environment for family, friends, mule deer and other wildlife species. Enhancing the home environment and replacing some of the lost wildlife habitat can be enjoyable and beneficial.

Seasonal Changes, Amazing Adaptations

Biking daily from Smithfield Canyon to USU campus, combined with an early am run, I’m well aware of the drop in temperatures, as are those of us who find themselves outdoors on a more permanent schedule. I’m speaking of our relatives who reside in the wild- birds, trees, raccoons, and such.

While I put on an extra layer or two, plants and animals have far more sophisticated adaptations from behavioral to physiological to structural.

We are all aware of the marvelous migration and hibernation behaviors, so let’s add a few more amazing adaptations to the list.

I’ll begin with a bird that is very common at our winter feeder- the Dark-eyed Junco. which responds to the first shortening days of summer with a series of physical changes: its reproductive organs become inactive and shrink in size, hormones stimulate the rapid growth of a new set of feathers, and fat deposits develop to provide fuel for the long migratory flight ahead.

Thus the preparation for migration starts as soon as the days begin to shorten. And the process must operate in reverse when the bird is in its winter habitat in the United States. As soon as days begin to lengthen, the Dark-eyed Junco must gear up physically for the flight north and breeding season. If it fails to do so, it likely won’t survive a long-distance migration. So the cycle of life and its related migrations and transitions are deeply connected to the heavens.

Plants are no less amazing. Those in temperate zones must also set their calendars accurately in order to flower and, for deciduous species, develop and drop leaves at the optimal time. Plants set their internal calendars using several attributes from the sunlight they receive. In fact, the angle of the sun may be more important to a plant than day length.

That’s because plant cells produce compounds called phytochromes in response to different portions of the light spectrum. Direct sunlight is higher in red light, while indirect sunlight contains more far-red light. During late fall and early winter, when the sun remains low in the southern sky, the indirect light produces an increase in far-red phytochromes.

As spring approaches and the arc of the sun rises in the sky, direct sunlight triggers the production of red phytochromes. The ratio of these two compounds mediates the hormones involved in flowering, leaf drop, and bud development. Even seeds below the soil are affected. The amount of red and far-red light that penetrate the soil is sufficient to govern germination.

Some behavioral alterations worth mention beyond migrating and hibernation are herding and flocking, huddling to share body warmth, dietary change, hair & feather change- both color and structure, and many more but my radio time is ending, so now it’s your turn to explore more! It really does make you appreciated the wonders of nature.

Our Barking Dogs, Coyotes

With the big game hunting season beginning, I reflect back on my first deer hunt in Utah. Arriving from Michigan in 1971, Utah friends took me into White Pine Lake above Logan. Alone on my stand, a large animal approached. Finely in my sights, a large, gorgeous male coyote in its prime. I fired and the coyote was dead before it slumped to the ground. Like Aldo Leopold after watching the “green fire” fade from the eyes of the she-wolf he shot, I resolved never to kill another coyote.

Since that long ago time, my admiration for this amazing animal has only heightened. It’s fascinating behavior, intelligence, and cultural significance are all worthy of mention.

Coyotes now occur throughout most of North America, as well as in parts of Latin America. It has been described as “the most vocal of all North American mammals”. Its penetrating range of vocalizations gave it the name Canis latrans, meaning “barking dog”. Its wild song awakens something deep within my primal being.

The coyote features prominently as a trickster figure in the folktales of America’s indigenous peoples. It was given the trickster role in light of its intelligence and adaptability. Some tribes, such as the Paiute, and Ute portray the coyote as the companion of the creator. In the Paiute creation myth, the coyote was created by the wolf as a companion, and the two created land by piling soil on the water-covered world. In Navajo mythology, the coyote was present in the First World with First Man and First Woman.

19th-century writers wrote of coyotes being kept in native villages in the Great Plains. Although shy, pups have been raised for hunting both as retrievers and pointers. In 1945 a tame coyote named “Butch”, had a short-lived career in cinema, appearing in Smoky and Ramrod before being shot while raiding a henhouse.

Coyotes were occasionally eaten by mountain men. It was sometimes featured in feasts of the Plains Indians, and coyote pups were eaten by the indigenous people of California. The taste of coyote meat has been likened to that of the wolf, and is more tender than pork when boiled.

At one location in Southern California, coyotes began relying on a colony of feral cats as a food source. Over time, the coyotes killed most of the cats, and then continued to eat the cat food placed by people who were maintaining the cat colony.

Fortunately, in my view, it is nearly impossible to eradicate coyotes from an area. Despite large-scale and expensive efforts to kill coyotes over the past 150 years, coyotes continue to thrive, as I was reminded on my run up SLC’s City Creek Canyon where two families on either side of the canyon serenaded on me.

Research suggests that when aggressively controlled, coyotes can increase their reproductive rate by breeding at an earlier age and having larger litters, with a higher survival rate among the young. This allows coyote populations to quickly bounce back, even when as much as 75 percent of their numbers are removed. For coexisting peacefully with this remarkable being, check out Projectcoyote.org.
Long live America’s song dog!
