I have the distinct privilege of working part-time at the Canyonlands Research Center, operated by The Nature Conservancy in Utah’s southeast corner. I live in northern Utah, so when I’m down there in the warmer months, I usually camp alongside some cottonwood trees that line the stream course of Indian Creek. The trees and shrubs create a green oasis amidst the surrounding desert of Bears Ears National Monument. Birds love it there, and I love to watch and listen to them.

This time of year, sunrise brings a raucous symphony of sound as a couple dozen species of birds raise their respective voices to attract mates and stake out territories. Nights are much quieter, of course, as most songbirds doze off in the darkness, conserving energy and avoiding nocturnal predators like snakes and raccoons. But in May, the midnight stillness on Indian Creek is broken by the loud calls of a unique songbird, the yellow-breasted chat.

Now, it’s not unheard of for birds to be active in the nighttime. But most nocturnal birds are not songbirds. The best-known, of course, are the owls. We have at least 12 species of owl in Utah, selecting different habitats from deserts to mountains to valleys and even towns. In the winter months, when I walk the streets of my small town before dawn, I occasionally hear great horned owls calling to each other. And a couple of summers ago, a pair of Western screech-owls raised two youngsters in the backyard.

Other Utah birds that are active at night include the aptly named black-crowned night heron. It may be seen in marshy areas at dawn or dusk, waiting by water’s edge to ambush prey animals such as fish, frogs, worms, mice and snakes. They can sometimes be seen during daylight hours – for example, at the Bear River Migratory Bird Refuge – but they tend to spend their days resting in dense bushes or trees.

Another nocturnal bird is the common poorwill, which breeds on dry, rocky slopes. You may never see one, as they blend in well with the ground they nest on, but you might hear the distinctive “poor-willip” call of the males, especially on a warm night at moonrise.

One songbird that sometimes sings at night is the Northern Mockingbird, famous for its mimicry and variety of songs. These striking gray birds are more common in southern Utah, but they’ve been found on Antelope Island, and my wife and I have seen a pair of mockingbirds at the very tip of Promontory Point, near where the railroad causeway heads west across the Great Salt Lake.

Then there’s the yellow-breasted chat. As the name suggests, chats boast a conspicuous deep-yellow breast, along with a long tail, and a greenish head with white spectacles, eyebrows and mustache. For many years, the chat was thought to be the largest warbler in North America – weighing twice as much as other common Utah warblers like the yellow warbler or the yellow-rumped warbler. But recent genetic analysis suggests that this species is actually quite unique – in fact, the only member of its own family.

Chats can be hard to see, as they tend to skulk in dense foliage. But they definitely can be heard. Their wide vocal repertoire includes whistling and cackling, meowing and cawing, chuckling and rattling, squawking, gurgling, and popping. Like the mockingbird, some chats may even mimic other songbirds.

So why sing at night? The advantage is that there’s less noise competition. Night-calling males in search of a mate can cut through the auditory chaos of springtime, with songs that carry far from their perch and increase the chance that they’ll be heard by a male-seeking female. The disadvantage, of course, is that predators can hear them, too.

It’s a tradeoff that the chat has evolved to make, and one that has enriched my nights, camping under the cottonwoods.

I’m Mark Brunson, and I’m wild about Utah both day and night.

Cache Valley Sugar Beets and German POWs

When I started teaching at Preston High School, one of the first books my English class read was The Diary of Anne Frank. I remember asking the class if they had any family stories of their own to share about those war years. A young woman raised her hand and said her grandparents had a painting on their wall that had been given to them by a German Prisoner of War. This POW had worked on their Cache Valley sugar beet farm in 1945. He’d signed the painting, and had written a few words of thanks on the back for the kind treatment he had received

I was astounded. German POW’s in Cache Valley? This led me to ask more questions.

I found out in 1945 there were close to 400 German POWs living in tents in a work camp at the Cache Valley Fairgrounds. Local farmers contracted with the US Government to hire the POWs to work in the fields for 80 cents a day.

Each morning the prisoners would get loaded into trucks and driven to a sugar beet field. The work day didn’t end until 8 pm when the prisoners returned to the Fairgrounds, damp and chilled, from the ride in the open bed trucks.

In 1945, sugar beets were a profitable crop, but labor intensive. In the Spring, the beets needed to be thinned and weeded. This work was done by a short handled hoe. In the Fall, the beets needed to be pulled out of the ground. This was done by a special beet knife with a big fish hook on the end. Once pulled out of the ground, the top leaves were sliced off and the beets tossed into a pile bound for the sugar factory.

At the peak of sugar beet farming in and around Cache Valley, there were 5 sugar factories operating. But by 1945 the factories were down to two – one located in Lewiston, and the other in Whitney, near Preston.

Native Americans came from Arizona to work the beets and set up their colorful teepees in downtown Lewiston. High school students were let out of school for 2-3 weeks in the Fall to work during what were called “Harvest Vacations.”

A friend of mine in Preston told me about a young man who went off the college in the Fall of 1945, but came home after a week. His father handed him a sugar beet knife and told him if he wasn’t going to go to college, he was going to work in the fields.

Everyone I met who once worked in the sugar beet fields told me all the work of thinning and harvesting needed to be done while bent over, and the resulting back pain was terrible.

Of all the stories I heard, my favorite was one of a Logan beet farmer who took his 3-year-old daughter with him to check on the work being done by the POWs he had hired. One day, he looked up and saw one of the German POWs holding his little girl in his arms. The farmer took his little girl by the hand, but the POW didn’t let go. A guard came running over. But both men stopped when they saw the tears running down the POW’s face. Somewhere, many miles away, they realized this German POW had a little girl of his own that he may or may not ever see again.

Today, all the POWs have long gone, as well as the local sugar beet farms. But if you drive north on Highway 89, just before you get to Preston, you can see the remains of the Whitney sugar beet factory. These huge crumbling buildings stand as a reminder that sugar beets were once king in Cache Valley.

A Day at the Chariot Races

Chariot Racing in Utah

A few weeks ago, I met someone who mentioned she used to be involved in chariot racing.

“Chariots?” I asked. “Like in ancient Roman days?”

“Sort of.” she said. She explained how today’s chariot racing in the Intermountain West involves two horses pulling a small aluminum chariot with the driver standing in the cart.

She mentioned the Regional Championships were coming up at the Golden Spike Arena in Ogden that weekend. So on Saturday, I jumped in my car . I got to the Arena just after the first race.

As I was strolling up to the rail running along the side of the racetrack, the horses in the next race shot by me. I was a little stunned by the hammering of the hooves on the dry dirt, the jangling of the harnesses, the strange whirring of the bicycle wheels — let alone the screaming of the spectators.

For the horses, it was an all out sprint for a quarter mile and it was over in 21 seconds.

In Roman times, the races lasted much longer. A typical race went 7 laps on a U-shaped racetrack with dangerously tight turns on both ends. Wealthy Roman Citizens owned the horses, but they usually sent a slave to drive the team. A crowd favorite was the daredevil slave charioteer Scorpius, who won 2,048 races before he died in a crash at the age of 26. Stories of chariot racing go all the way back to Homer’s Iliad where the Spartan king Menelaus was accused of cheating in a chariot race.

Rome’s racetrack was called the Circus Maximus and it could seat 250,000 spectators.

Back in Pioneer times in Utah, farmers liked to brag about how fast their horses could go, so challenges were made, and the issue usually settled by an informal race. The first official chariot race took place down the main street in Jackson Wyoming in 1950. For the following decades, chariot racing was very popular. Hundreds of teams would show up at the local races.

Going back to the Golden Spike racetrack, I walked up to where the races were starting. I asked if I could get close and climb up on the sidebars of the starting gate and they said ,”Sure.” From there I got an eyeball-to-eyeball view of the horses impatiently banging around in the starting chutes.

I think I was expecting a “Ready, Set, Go” and a starter pistol fired into the air. What I got was a mighty clang of metal on metal when the starter pulled a lever. The gates slammed open, the horses lunged forward, and dirt flew by me.

When the dust finally settled, the days winners were a team from Logan, who clocked in at 20.40 seconds – just 3 hundredths of a second off the world record.

On the way out I stopped to talk to three old timers still standing around chewing the fat.

“The sport is dying out,” one said.

“It’s getting expensive to keep a horse,” said the second.

The third summed it all up for me:
“Used to be you were really someone if you had a car. Now you’re really someone if you have a horse.”

This is Mary Heers and I’m Wild about all the horses in Utah.

A Long Winter’s Nap

One of the lesser-known natural, and underappreciated, areas in our state is found 32 miles south of Vernal in eastern Utah: the Ouray National Wildlife Refuge. My wife and I visited last July, hoping to see bird species we don’t find in other parts of the state. We enjoyed the birding, but what made the visit most memorable to me wasn’t birds, but fish.

The refuge lies along the Green River, the largest tributary of the Colorado. If you drive far enough down the main refuge road, you’ll come to the Ouray National Fish Hatchery, dedicated to protecting three of the rarest fishes in North America: the bonytail, the humpback chub, and the razorback sucker.

All three of these species are confined to the Colorado River watershed, and all are on the federal Threatened and Endangered Species list. They’re desert fish, used to warm water. In fact, I learned that one reason why populations of these fish declined in the 1960s was that construction of the Flaming Gorge Dam upstream had made the Green River much cooler, as the water flowing through the dam was drawn from the coldest depths of the reservoir. That was great for trout, turning a 30-mile stretch of the Green into a world-renowned fishery. But it wasn’t so good for desert-adapted fish.

Learning this made me curious. The Ouray refuge is in the Uinta Basin. and it gets cold in the Basin in the winter. So, if cold water is bad for them, how have the bonytail, humpback chub, and razorback sucker survived there for thousands of years?

To answer that, it helps to understand the terms that anglers and fisheries biologists use. They refer to cold water species, like trout, kokanee, and whitefish, and warm water species like bass, perch, and catfish. The rare Green River species are warm water fish. But those labels aren’t about what temperatures the fish can survive, they’re about temperatures they experience when they thrive – during the warmer half of the year.

All fish are cold-blooded. More specifically, they’re ectothermic, getting their body heat from their environment, and poikilothermic, having a body temperature that fluctuates with the temperature of the waters where they live. To survive in winter, they go into a low-energy state called “torpor.” Their heart rate drops, their metabolism slows to a crawl, and their need for food is basically nonexistent. It’s like hibernation, except it happens in the deeper, slower water of a river instead of a cave or burrow.

That’s an important adaptation for the Colorado River fishes. Bonytail and humpback chub feed on insects, crustaceans, seeds and plants, occasionally small fish, all of which are much harder to find in the winter. Razorback suckers eat insects, plankton, and decaying plant matter – also less available in the winter months.

Now that we’re heading into springtime, when the weather gets warmer and the river along with it, both the fish and their prey are becoming active again.

Temperature is no longer a big threat to survival of these species. Flaming Gorge Dam has been re-engineered so that warmer water is drawn through its turbines. Also, flows through the dam are altered during spawning season to increase survival of fish larvae. The Ouray hatchery raises young fish to boost their population. The biggest threats to these species are habitat destruction and competition from non-native fishes. Those are challenges that are much harder to address. But it’s good to know there are biologists helping to recover the rare native fishes of the Green and Colorado Rivers.

I’m Mark Brunson, and I’m wild about Utah’s aquatic species and habitats.
