Tucked into isolated pockets of the Uintah Basin’s arid wildlands is the best little plant you’ve never heard of. Known to exist only in Duchesne and Uintah Counties, Shrubby-reed Mustard seems to occupy only the semi-barren “islands” of white shale in areas of the Green River Formation’s Evacuation Creek region. The endangered plant features thick, almost succulent, blue-green leaves and small yellow flowers.

“The habitat of Shrubby-reed Mustard is visually striking,” says USU alum Matt Lewis, a botanist with the Bureau of Land Management in Vernal, Utah. “It grows in very shallow, fine-textured soils and shale fragments that form narrow bands in the desert shrub community.”

Among the first plants to flower in spring, the perennial herb is visited by large number of insects, including many native bee species that forage for pollen. Scientists believe these bees may be critical in the plant’s reproduction and survival.

Lewis says the plant, also known as Toad-Flax Cress and Uintah Basin Waxfruit, offers an understated beauty to the stark landscape. With a shrub-like form and multiple stems, Shrubby-reed Mustard grows to about 20 centimeters in height. Its leaves, which feel almost like leather, change to a bright purple in the fall.

The plant is also enticingly fragrant, Lewis says. “Its scent reminds me of roses mixed with apples and pears.”

Despite its fragile status, Shrubby-reed Mustard is a long-lived plant. USU ecologist Geno Schupp says some individual plants may be one hundred years old.

The elusive species has outlived scientists’ attempts to classify it and has undergone several taxonomic changes. It currently boasts the scientific name Hesperidanthus suffrutescens, placing it solidly in the mustard family.

Lewis knows of no history of Shrubby-reed Mustard as a culinary or medicinal herb, though documented reports of such uses for mustard plants date back to ancient times. The plant appears to provide welcome forage for some four-legged creatures, he says, as he recently witnessed plants that had been grazed completely and ripped from the ground.

“Whether that was due to livestock or native ungulates, I’m not sure.”

J.J. – Here in Red Butte Canyon we monitor migratory songbirds as they move through and try and get a picture of one, what is the bird community like in Utah. That’s why Red Butte Canyon is such a nice place to work because it’s a protected canyon so it gives an idea of what the natural state of birds along the Wasatch should be like. And we monitor their populations, look for any population level changes, and we look for changes in their migration, in the health of the birds, and try and understand how human effects like land development and climate change are affecting these bird communities.

Ok, so we’re ready to go around and check our nets.

Anna – The mist net is this really superfine, hard to see material with shelves in it. So when the bird flies into the net it kind of falls into one of these net shelves and that material is so fine, especially if you put it in front of a tree, that the birds don’t see it and so they’ll just fly right into it, fall in, and we come around frequently enough that they’re not in there for a long time.

J.J. – So this is a bird called a spotted towhee and based on how brown that head is

Blowing the feathers away from the body allows researchers to examine a bird's fat levels and overall health. An inspection of this spotted towhee also reveals a brood patch, indicating it is incubating eggs.

Anna – And the eye color, right?

J.J. – and the eye color, we can tell that it’s a little baby, just born this year. Towhee squawking in the background. When the bird lands in the net like this they get all tangled up, they get the net around their wings and around their legs, and so what we do is we carefully take it off of any part of their body where it’s tangled up and then we put them in these little bird bags. And the bird bags are just little cloth sacks that keep the bird warm and because they’re kind of dark the bird stays really calm.

Blowing feathers away from the head reveals the skull beneath, enabling the bird's age to be determined. The pattern of skull ossification on this black-headed grosbeak (Pheucticus melanocephalus) indicates it is an adult.

Jennifer – It’s a baby yellow warbler!

Kylynn – Spotted towhee.

J.J. – Black-headed grosbeak.

Mourning dove.

Kyle – Song sparrow.

J.J. – So this is a yellow warbler. So as part of the banding we take the age and the sex and then a bunch of morphological measurements. We can tell this one’s a male by those brown streaks on the breast and we can also tell it is an older bird. It’s been around for at least one year because of that nice yellow edging on those tiny feathers there.

Let’s say a CP of one. A CP is a cloacal protrusion, it’s what males get when they’re breeding. Sound of blowing. No brood patch. Brood patches are where birds will loose feathers on their stomachs so they can incubate eggs. Sound of blowing. No fat. Birds deposit fat in a really predictable way. They have a little cavity where their collar bone is. Sound of blowing. No body molts. Not growing any feathers on his body. Wing is sixty-two and his weight is 8.4.

If anyone is interested in helping out bird conservation just in their day to day life, if you have cats either keep them inside or buy them a cat bib or a couple of bell collars. That’s probably the number one thing you can do to help bird conservation.

Everyone – For Wild About Utah this is the Şekercioğlu lab in Red Butte Canyon!

[Sounds of a bat echolocating]

Jessie Bunkley – The sound you are hearing is a bat echolocating through the darkness of the night. Bats use sound to detect their surroundings. They produce frequencies that are much higher than what we’re able to hear and as those sound waves hit objects in front of them and reflect off the bats interpret the echoes to sense their environment. What you’re hearing is a bat detector that has taken these high frequency sounds and cut them down to a level that we can hear.

Adam Brewerton – I’m Adam Brewerton. I’m the wildlife conservation biologist for the Northern Region with the Division of Wildlife Resources.

Jessie – And I’m Jessie Bunkley. I’m a wildlife technician with UDWR.

Adam – And our bat survey tonight out at Antelope Island we’ve been pretty successful so far. We’ve caught a little brown bat and we’ve caught seven Townsend’s big-eared bats. It’s part of the statewide species distribution and occupancy study and we’ve got several survey locations that have been randomly selected out of a grid system. So Antelope Island is just one of those randomly selected sites. In addition to that it’s also close and convenient for people to come out and learn about bats so that’s why we’ve invited [the] public to come out and join us tonight.

Jessie – To capture the bats we’ve set up several mist nets, which are very long, fine nets. We have stacked the nets two or three nets high and we use a pulley system to raise and lower them.

Adam – They fly into the net and they get caught and tangled. We go get the bats out as gently as we can and we come back for the measuring and weighing and identifying. It helps us to track relative species occurrence throughout the state. So being able to say that the species is doing well or declining or increasing. We can really only say that based off of how frequently we catch it in different places relative to other species.

Jessie – Bats are the second most diverse group of mammals, right behind rodents. There are over twelve hundred species of known bats throughout the world and this represents about twenty percent of all mammals. In Utah we have eighteen species that regularly occur in the state.

Adam – The wing membranes connect all their fingers together so their hand is shaped very much like ours, their thumb sticks up with a little claw hook on it, and then that membrane stretches between their finger digits. They’re cool because they’re interesting, they’re unique, they’re the only mammals that fly, they’re skeletal structure is totally different than other mammals, they echolocate, they’re intelligent, social, they live in a completely foreign world that we can’t really understand how they view the world through echolocation. What makes them interesting too is just so much that we don’t know and [there is] so much more to learn about them.

Jessie – For Wild About Utah that was Adam Brewerton and I’m Jessie Bunkley signing off from Antelope Island State Park.

Rufous Hummingbird-Who doesn’t love hummingbirds!

Who doesn’t love hummingbirds! I’m always amazed how a tiny life form with a brain smaller than a pea is capable of such amazing intelligence and behaviors. In fact, a hummingbird’s brain is proportionally larger in size to their body than that of any other bird. And like the corvid family (jays, magpies, and crows), research has found that hummers have an amazing memory.

Now is the seasonal peak for hummingbird activity with young birds fresh off the nest. One of my favorites, the migrating rufous hummingbird, may join the milieu on their long distance marathon as they make their way from as far north as Alaska to winter in Mexico.

The feistiest hummingbird in North America, the brilliant orange male and the green-and-orange female are relentless attackers at flowers and feeders. These fearless competitors will challenge even the largest hummingbirds of the Southwest, which can be double their weight, and often win the contest! Rufous Hummingbirds are wide-ranging, and breed farther north than any other hummingbird. Look for them in spring in California, summer in the Pacific Northwest and Alaska, and now in the Rocky Mountains as they make their annual circuit of the West.

Rufous Hummers have the hummingbird gift for fast, darting flight and pinpoint maneuverability. Like other hummers, they eat insects as well as nectar, taking them from spider webs or catching them in midair.

Rufous Hummingbirds breed in open areas, yards, parks, and forests up to timberline. On migration they pass through mountain meadows as high as 12,600 feet where nectar-rich, tubular flowers are blooming. Winter habitat in Mexico includes shrubby openings and oak-pine forests at middle to high elevation.

They may take up residence (at least temporarily) in your garden if you grow hummingbird flowers or put out feeders. But beware! They may make life difficult for any other species that visit your yard. If you live on their migration route, the visiting Rufous is likely to move on after just a week or two.

Regarding feeders, make sugar water mixtures with about one cup of sugar per quart of water. Food coloring is unnecessary; table sugar is the best choice. Change the water before it grows cloudy or discolored and remember that during hot weather, sugar water ferments rapidly to produce toxic alcohol. If you are among those who have these dazzling sprites of amazing life stop by, consider yourself fortunate indeed!
