Beaver Tail Slap

When I first saw a beaver in Cache Valley I thought I’d seen an alligator. I was sitting in the front of a canoe when a large head shot past the bow followed by a black tail that flew into the air and came down on the water with a resounding slap

“What was that?” I asked
“I don’t know,” my friend answered
“I think it was an alligator,” I said
By then then creature had disappeared and we paddled on.

I found out later that tail slapping is a common beaver behavior. Its a warning shot before the beaver dives for cover.

Intrigued, I set out to learn more. It came as a surprise to me to find out that when a beaver builds a dam, it is actually building a home. Inside a sturdy wall of sticks, rocks and mud, the beavers build a living space above the water line. It’s dry – and its safe because it can only be entered by swimming through underwater tunnels. Not a problem for a beaver who can swim underwater for as long as 15 minutes.

When the surface of the pond freezes over, the females will give birth. Its an extended family life – an adult pair, the yearlings, and the new kits. When winter is long, and with so many mouths to feed, the beavers have perfected their food storage. Hauling their favorite food, aspen , back to the lodge, they jam it into the muddy bottom of the pond. There is stays, fresh and crisp like any refrigerated food, until its needed.

When fur trappers arrived in Northern Utah in the 1800’s, European hat makers had discovered that felted beaver wool made the very best hats. Bear Lake became a hot spot. The historical marker just north of Garden City tells us,

“Donald MacKenzie, Jim Bridger, and a host of famous beaver hunters operated here. Two major summer frolics and trade fairs brought plenty of excitement to Bear Lake in 1827 and 1828.”

Trappers were harvesting up to 500 lbs a year. But by 1840, the beavers had become almost extinct. European fashion in hats moved on to silk – a good thing for the hat makers as well because the mercury used in the felting of beaver wool caused all kinds of neurological disorders. Its no joke the Hatter in Alice in Wonderland is mad.

Back in northern Utah, the beaver population slowly rebuilt, but the human population also grew and conflicts arose. Recently a farmer in Benson became irate when beavers began to redirect the flow of water through his irrigation canals

It’s the job of the Utah Division of Wildlife Resources to live trap and relocate these beavers. I was lucky to be allowed into the loop at this point.

When I picked up one of the smaller beavers, I could feel its heart going a mile a minute under my fingers. But it settled down as I sat in a chair holding it against my chest while it got a quick physical checkup.

Holding the beaver close, I had a good look at the nibble fingers on its front feet, the webbing on its back feet that can paddle along at 6mph, and the marvelous flat tail, a good rudder for swimming, a prop for standing on land, and perfect for slapping the water’s surface.

Take my word for it, once you’ve seen this slap up close, you won’t forget it.

American White Pelicans

I first caught sight of the eight pelicans swimming in s straight line towards the waters edge, looking a lot like a tank division in in an old WWII movie I slammed on the brakes just in time to see them all dip their bills into the water, come up spilling water and cock their heads back And then, gulp! Fish slid down their throats.

Wow, I thought. These pelicans are working together to to drive the fish into the shallow water’s edge where they can easily scoop the up And then it got better. Fanning out, the pelicans regrouped in a circle Swimming towards the center, they tightened the noose. And bam! Dip, scoop, knock back some more fish

I was amazed at how soundless and seamless it all was and could have watched for hours, but I was on the one lane auto route at the Bear River Migratory Bird Refuge and the cars behind me were starting to honk their horns, so I reluctantly moved on.

As soon as I got home I plunged into research on this majestic bird, beginning with the bill. When the pelican dips its bill into the water, the lower portion expands into a flexible sac that allows the bird to to scoop up as much as 3 gallons of fish and water. When the pelican cocks back its head, the sac contracts, the water is expelled through a barely open bill, and the fish swallowed. The huge pelican bill, which at first glance looks like a formidable weapon, is actually an exquisitively designed fishing net.

Archeologists have found pelican skulls dating back 30 million years, so this unique bill has definitely passed the test of time.

Back at the refuge I was able to turn into a visitor pull out and pick up the rather stunning bit of information: these pelicans fly in from Gunnison Island in the Great Salt Lake, over the Promontory Mountains, daily to forage for fish. That’s a 30 mile trip each way!

Long before the Mormon pioneers arrived in Utah, pelicans were building their nest on Gunnison Island. They were briefly disturbed when an artist, Albert Lambourne, tried to homestead for a year in 1850, and a guano mining company dropped off a crew – a Pole, a Russian, a Scot and an Englishman- to mine the bird poop. But the operation wasn’t profitable, and when it closed down, the pelicans reclaimed the island. Each March the birds fly in from as far away as Mexico, build their nests, and raise their chicks. The rookery is the largest in the US. In 2017 the pop was estimated to be as high as 20,000.

Back in Cache Valley in 2010, Jordan Falslev built a viewing platform near Benson Marina, The Pelican Perch, as his Eagle scout project. There used to be hundreds of pelicans out there on the water, but when I stopped by last week I didn’t see a single one. Numbers are way down now largely because the dropping water level in the Great Salt Lake have exposed a land bridge to Gunnison Island that allows predators to ravage the nesting site.

You can still catch sight of a pelican in flight in Cache Valley. (Their wingspan is 10 ft. Rudy Gobert, in comparison, has a wingspan of 7 ft 9 in.) But for my money, the best show in town is watching packs of pelicans hunt for fish at the Bear River Migratory Bird refuge.

Black Bear Country

As I hopped out of my car to take a short hike up Cache Valley’s Dry Canyon Trail I was surprised to see the Utah Department of Wildlife Resources had posted a picture of a black bear. “Bear Country,” it said. “Store food safely and keep campsites clean.” I’ve never seen a black bear in Utah but a quick check of the DNR website confirmed that as of last count, July of last year, there were 4,000 black bears in Utah. In winter the bears stay out of site. But by May they are coming out of hibernation looking for food and very hungry.

Now I’ve always envied the bears ability to go to sleep fat in the fall and wake up thin in the spring. For me this would be the ultimate diet plan. But on further investigation I found that hibernating bears are not simply sleeping. They do slow down. The heart drops from 50 beats a minute to less than ten. Its breathing slows to once every 45 seconds. The body temperature drops almost ten degrees. The bears do not get up at night to pee. Amazingly, the bear does not eat, drink, urinate or defecate for months.

People who study bears tell us that keeping this hibernating metabolism going takes 4,000 calories a day. So having burned through their fat reserve the bear comes out of hibernation in the spring very Interested in food. The problem occurs when bears discover human food because once having tasted it they want more.

My daughter once told me about a camping trip she had taken in the Wind Rivers where a bear came into their campsite at midnight. She and her friends jumped out of their tents and saw the bear climb the tree where they had hung their food. For four hours the bear worked at getting that food. Finally, the tree branch broke and the food bag crashed to the ground. The bear ate their bagels, every single chocolate covered espresso bean, everything except the jalapeno crème cheese.

I took one last look at the poster at the trailhead. The small print said, “Learn to live with bears.” I thought some people learned more slowly than others. I remembered a trip I had taken to Yellowstone National Park and reassured my out of town guest that the National Park Service had solved the problem with bears. To my chagrin when we were checking in the camp host told us that they were having trouble with the bears. “It’s toothpaste,” the lady said, “They like the sweet taste of toothpaste.” I wasn’t worried until the next morning when my guest confessed she had remembered her toothpaste was still in her jacket inside the tent. “Ah, let the bear make its choice,” she sighed as she drifted off to sleep. No bear came into the campsite that night.

Sometimes you just get lucky.

Discovering Honeybees

I was a bit surprised when I met a local beekeeper who insisted she’d never eat any honey except that produced by bees in the mountains above Cache Valley. It made sense that the taste of honey would be determined by the flowers where the bees collected nectar and pollen. It turns out the Forest Service issues permits to local beekeepers to put hives around Tony Grove

Wanting to know more, I dropped into the Honeyland store in Cache Valley and was soon mesmerized by the active cut-away hive on display. It was a teacher’s dream come true – hundreds of bees – all diligently on task. Wide-eyed, I watched as a bee flew in at the bottom of the screen through a tunnel under the window looking very much like a bike rider with two full paniers She deposited the full sacks of pollen and then she began to dance. This took me quickly to the internet to learn more.. The bees dance is called a “waggle dance” – a straight line calibrated to communicate how far away the food source is, and a circular return arc to orient the path to the food. The waggle dancing bee can direct her sisters to a food source up to five miles away.

It takes 550 worker bees visiting 2 million flowers to make 1 pound of honey.

Top speed for a bee is 15 mph.

Each honey bee makes one twelfth of a teaspoon of honey in her lifetime.

I soon returned to the store’s cut away hive and finally found the queen – a bit tricky as she looks like all the others except she’s one and a half times bigger. I watched as she dipped her tail into one hexagonal cell after another. On a good day a queen will lay 2,000 eggs.

Busy, busy bees working together to set aside enough honey to feed themselves during the winter.

The poet Dick Paetzke once called honey “the soul of a field of flowers”

Mountain honey looks and tastes a little different than honey made by bees pollinating Cache Valley alfalfa. Both are incredibly delicious.

Aristotle got it right: “Honey is the nectar of the gods.”
