“Make hay while the sun shines” is a venerable bit of farm wisdom that encourages cutting and drying of hay during fair weather. One, two, possibly three cuttings of alfalfa hay have been baled and stacked this summer by Utah’s farmers to feed dairy cows and horses this winter. More traditionally, ranchers have cut meadow or marsh hay to be piled in the lofts of their barns.

Utah’s first haymakers were not ranchers at all, however. These earliest haymakers cut hay for their own consumption. To see and hear these daytime haymakers, you must travel high into our mountains, to 9,000 feet or higher. Look for a boulder strewn talus slope or rockslide. Listen for this call….. if you hear it, you have found the pika, our first haymaker. That call was either declaring the pika’s individual territory or an alarm announcing you. These rounded relatives of our rabbits resemble a tawny-coated chinchilla or a plush, plump guinea pig. They have nearly circular small ears and no apparent tail.

All day long during the alpine summer, pikas are busy cutting grasses, sedges and wildflowers from neighboring meadows. They haul this back by the mouthful to tuck in crevasses in their stony stronghold to dry. These stockpiles are their winter larder. You see, unlike their alpine kin, such as marmots, ground squirrels and chipmunks, our pikas don’t burrow and they don’t hibernate. Unlike the snowshoe hare, pikas don’t get out much either once the snow flies. Under the snow pack, they simply dine on hay.

Pikas are strange little lagomorphs
(relatives of rabbits and hares)
that live in rocky areas and talus slopes
in alpine habitats in much of the
mountainous western US and Canada.

In Utah, poke around for pikas amid high peaks along the mountainous central spine of our state, from the Uintas south to Brian Head, wherever peaks reach toward tree line and you can find. There you may find pikas making hay or loafing atop prominent stones in their rock jumbles, or contributing to the territorial calls of their talus slope choir. Their intolerance of heat keeps them from spreading downslope. Like the moose, they are one of the animals that will fare poorly with significant climate warming. For now, though, you can continue to peek for picas amid Utah’s glorious alpine scenery.

Moose in Utah

Hi, I’m Dick Hurren from Bridgerland Audubon Society.

If you’ve spent much time in the forests and wetlands of northern Utah, you may have been lucky enough to see one of North America’s most magnificent animals, the Moose.

The Moose is the largest member of the deer family, and one of the largest mammals to survive the last Ice Age. Utah’s subspecies of Moose is known as the Shiras,
or Wyoming Moose. Although the smallest subspecies of Moose in North America, it can grow to be nearly six feet tall and weigh as much as 1,000 pounds. Bull Moose
can grow a rack of antlers that reaches four feet across.

One might assume such an ancient and enormous animal has long existed in Utah, but in fact the Moose is one of Utah’s newer immigrants.
The first Moose in Utah were seen about 100 years ago, and the total population may have been less than 100 animals as late as the 1950s. Today, there are about 4,500
Moose throughout northern Utah. So how did the Moose become so plentiful in such a short time?

The Moose’s immigration to Utah looks like a case of perfect timing. Many of the Moose’s predators like Grizzly Bears, Wolves and Mountain Lions had been largely
exterminated. At the same time, logging was replacing mature forests with new meadows and scrub that Moose prefer. The combination of young growth and wetlands provided
the ideal habitat for Moose to thrive.

On top of these favorable conditions, human management has helped the Moose expand. Overwhelming demand for Moose hunting
has fostered strategies to encourage population growth.
More recently, there have been attempts to speed up the expansion of Moose by transplanting them to new mountain ranges.

Despite success in the last hundred years, Moose face many challenges in the next hundred. Maturing woodlands will be able to support fewer Moose.
Old predators are rebounding slightly and will take their toll. But the most difficult challenge the Moose may face is that of climate change.
The Moose evolved to survive in extreme cold climates. If temperatures continue to rise, the Moose will retreat
higher into the mountains and further north until one day this recent visitor returns to Wyoming or even further north.

The next time you visit the mountains, pay close attention to the streams and lakes particularly those surrounded by willows.
And you too may be lucky enough to see the moose.

The Eyes Have It

Hi, this is Holly Strand for Stokes Nature Center located in beautiful Logan Canyon.

A few years ago, I was working for World Wildlife Fund in eastern Montana. One night, we were doing a nocturnal survey of the black footed ferret, the most endangered mammal species in North America. We were counting reintroduced ferrets by riding around in a truck with a large spotlight mounted on top. When the spotlight hit a ferret, we could see the emerald green glow of its eyes as the animal looked back at the light. We’d stop the truck, walk toward the green points, and confirm the presence of a curious ferret for our census count. If the glowing eye color was something other than green we kept on driving. It was during this nocturnal safari that I learned about animal eye-shine and how it can be used by hunters as well as naturalists in finding target species.

Eyeshine occurs when light enters the eye, passes through the rods and cones strikes a special membrane behind the retina, and is reflected back through the eye to the light source. This special mirror-like membrane, called the tapetum (ta-PEA-tum), is not present in the human eye. The light-capturing system allows light to pass through the eye twice, and it is one way a nocturnal animal increases its ability to see in dim light. It’s the tapetums cause the eerie glow that we see in a housecat’s eyes caught in a light or when our car headlights surprise a deer, or badger.

The color of eyeshine varies from species to species. Most owls have red eyeshine. Coyotes as well as mountain lion shine greenish-gold. Elk and deer – varies from silver white to a light silvery green or light silvery yellow. Desert cottontails’ are red. Tiny pricks of light may signify the presence of wolf spiders or moths. Even certain fish have eyeshine.

To see eyeshine in the wild, just take a walk on a relatively dark night, and hold a flashlight on top of your head so that you are looking down the beam. Direct the beam at bushes or low vegetation. Chances are, you’ll see the pink-tinted eyeshine of spiders. Near water, look for the greenish glow of frogs’ eyes. Keep the beam directed at the eyeshine and move closer until you can spot its owner. Bigger animals like deer or raccoons will be farther away so you may want to use binoculars in combination with a light, lining up the field of view with the light beam, and then moving the two in unison. Searching for eyeshine is the perfect summer night activity, so grab your flashlight and go out and experience some real Utah night life.

This is Holly Strand for Wild About Utah.

The Bear Facts Old Ephriam

The Bear Facts Old Ephriam: Click to visit UtahMountainBiking.com Copyright 2001 Bruce Argyle, Photographer
Twelve miles up the Logan Canyon in the Bear River Range of the Wasatch Mountains is the grave of Old Ephriam, the last grizzly bear seen in Utah. He was trapped and shot in 1923 by Frank Clark, a sheepherder from Malad. Clark, an animal lover–except for bears–doggedly tracked Old Ephriam for 10 years during which the grizzly poached local sheep with impunity.

The name “grizzly” is based on the fact that bears in North America’s interior have hairs with white tips, resulting in a “grizzled” appearance. Many think the grizzly is a separate species, but in fact, the brown bears of North America, Northern Asia and Europe are all local variations of the same species–Ursus arctos. Brizzly, Kodiak, Manchurian, and Siberian brown bears may differ in size and color, but they all share a characteristic shoulder hump, a dished face and extra long claws so good for digging.

Old Ephriam was said to be a “giant grizzly”, weighing in at around 1,100 pounds. Such a weight would be unremarkable for a costal Alaskan brown bear, which can reach up to 1,500 pounds. But, because of their more limited food supply, interior brown bears, such as Old Ephriam, usually range between 225 and 670 pounds. Thus, it is very likely that the 1,100 pound figure might just be the product of good storytelling.

Today, you may visit utah’s most famous brown bear in two different places. Old Ephriam’s skull is on display in the Tanner Reading Room of Utah State University’s Merrill-Cazier library in Logan. But maybe the best way to pay your respects to this Utah celebrity is to hike to his old stomping grounds northeast of Logan. His grave is six miles up the right-hand fork of the Logan river. A large stone monument, built by the Boy Scouts in 1966 lies near the 1923 gravesite.
