Shorebirds

Shorebirds in August? I’d been told there was a robust migration during that time, but hadn’t tested the validity of such until a week ago. Three other young ladies joined me to do a count at the Salt Creek Wildlife Management Area near Tremonton Utah. And boy did I need their younger eyes and energy as we were inundated with shorebirds- avocets, stilts, curlews, greater and lesser yellowlegs, dowitchers, marbled godwit, western sandpipers, killdeer, and a flock of small peepes (short for small sandpipers).

Myriad other magnificent migrants joined the mixed flock- numerous duck species, juvenile black crown night herons by the dozens, herons, egrets, ibis, terns, etc., but they don’t qualify as shorebirds, so we enjoyed their presence, but they didn’t make the list.

A few other non-migrants were noteworthy- a burrowing owl that posed beautifully on a fence post emitting constant chatters, and a very fat, mature western rattler with many buttons on its tail./ The Salt Creek WMA is a jewel that gets few visitors given its “out there” location competing with the 80 thousand acre Bear River Migratory Bird Refuge next door, which boasts an outstanding visitor center, offering many resources and educational programs.

This was the first official fall shorebird survey conducted in 30 years at roughly 200 sites across 11 western states. These surveys fill a critical three-decade data gap in our understanding of migratory shorebird populations and their distribution. The results will inform management and policy efforts to ensure there are resources to support birds and the places they need during their migratory journeys.

The survey was organized by the Sageland [Collaborative] organization, Utah Division of Wildlife Resources, and several others, conducted by volunteers and biologists via airplane, vehicles, ATVs, boats and on our feet. This survey will occur for the next three years, during the same week each spring and fall, to coincide with the peak shorebird migration across the region.

We’re part of the Great Salt Lake ecosystem, whose wetlands support nearly one-third of the global population of Wilson's phalaropes, more than half of American avocets, 37 percent of black-necked stilts, and 21 percent of the North American population of snowy plovers.

Shorebirds are a diverse group of birds including sandpipers, plovers, avocets, oystercatchers, and phalaropes. There are approximately 217 recognized species globally, 81 of which occur in the Americas for all or part of their lifecycle with 52 species breeding in North America, many of whom visit Utah.

Shorebird are the endurance marathoner winners, some migrating 20,000 miles a year. Their remarkable hemispheric travels coincide with peak abundant food. In their global pursuit of food and breeding grounds, home is nowhere, yet everywhere. As a result, shorebirds are difficult to track, monitor, and protect. /Shorebirds are among a few groups of birds showing the most dramatic declines. Their decline began in the 1800s, in part due to market hunting. As humans have continued to alter the landscape, shorebird populations have further decreased, with declines increasing rapidly in recent decades.

Sheep, Salt and the Great Salt Lake

Great Salt Lake

All of last year, the news about the Great Salt Lake was going from bad to worse. We began to hear dire predictions that the shrinking lake might disappear altogether.

Then, finally, with some legislative action and a big boost from record snow and rain, the water level began to rise. The marina on the southern tip of the lake opened up.

I grabbed the chance to take a boat ride out onto the lake. The water was calm and smooth and Fremont Island loomed large ahead. We were the only boat out there.

Ah, I thought, this is a lot like Kit Carson and John Fremont must have seen the island when they paddled up to it in 1843.

The boat operator told us some early history of the island. In 1859 two brothers, Henry and Daniel Miller, took 153 sheep out to the island and left them there. It seemed ideal – plenty of grass, adequate fresh water’ and no wild beasts. So, no need to leave a herder.

The brothers returned periodically to shear the sheep. They also built two huge vats, lit a fire of sagebrush under them, and boiled the lake water down to salt.

Business was good. Boatloads of salt were sold to the silver mines in Montana who needed it in their operations. The excess lambs were taken to market and sold.

By now the sheep, left alone on the island for long stretches of time, were becoming wild as deer. One roundup, some sheep were so determined not to get caught that they took off swimming away from the island. They were still going when they disappeared over the horizon.

But the story really took a turn when a judge from Salt Lake, Uriah Wenner, took advantage of the Desert Land Act intended to encourage irrigation and farming in the west. He filed a claim on the island and evicted the sheep. It was 1885, and Jacob Miller, now in charge of the Miller family sheep operation on the island was a polygamist “in hiding.” He didn’t dare go to court to challenge the claim.

As the last of the sheep were taken off the island, they were placed in the custody of an experienced herder. The herder was just beginning to cook his breakfast in his hut.

“You’d better watch these sheep,” he was warned.

“Don’t tell me how to herd sheep,” said the herder.

He finished his breakfast. When he came out of his hut, the sheep were gone.

The story ended, but the best was yet to come. The boat stopped and my husband and I slid into the water off the back of the boat.

Gleefully we bobbed around like corks. It was impossible to sink. I flipped on my back and stretched out. It would have been easy to doze off. Buoyancy at its best.

The current salinity of the Great Salt Lake is 16%. That’s just about halfway from the oceans at 3½ and the saltiest water on earth – the Dead Sea at 33%

The Great Salt Lake is our unique treasure. But it’s future is still at risk. Will we keep it or lose it?

Toxic Plants

I just returned from southern Indiana, another “Land of Lincoln” where I visited a beautiful monument featuring Abraham Lincoln’s early life on a farm carved from the Indiana wilderness. In 1818, Abe’s “angel mother” as he described her, suffered a violent death called milk sickness. Further reading on the interpretive sign told how a plant called white snakeroot had a toxin, which was transferred to the milk and meat when ingested by livestock.

Of course, we have our toxic plants here in Utah as well. One that is reported to have caused death in humans and livestock is the foothill death camas, one of a few extremely toxic plants found in our area, and a very common early spring plant throughout much of Utah’s foothills.

Death camas plants include several species of Zigadenus. At least 15 species are native to North America and grow in all kinds of habitats: moist mountain valleys, dry hills, forest, grassland, and even coastal and marsh areas. There may be some variation in toxicity level from one species to the next, but ALL should be considered dangerous.
I became aware of this beautiful member of the lily family when one of my more adventuresome students shared his story. As a 10 year old, he decided to experiment by eating some of the foothill death camas. Soon after he was rushed to the ER to have his stomach pumped. He reported there was no further experimentation!

Symptoms of poisoning by death camas include vomiting and excessive salivation, tremors, weakness, loss of control over body movements, convulsions, and coma. Ultimately, an animal that has eaten too much will die. A half pound consumed can be fatal to livestock.

It is possible to mistake death camas for the edible blue camas lily, sego lily, and wild onions, all of which were an early staple of native Americans and pioneers. More recently, some unfortunate railroad workers died shortly after eating the bulbs. Eight adults ingested foothill death camas (Zigadenus paniculatus) bulbs in Juab County, Utah, believing them to be nontoxic wild bulbs. All who ingested the bulbs became ill, and three of them required admission for medical treatment.

The probable fatal dose, extrapolated from animal data, ranges from less than one-tenth pound (four-five bulbs) for a young child to a pound for an adult. Other parts of the plant such as nectar and seeds are also highly toxic. Atropine and dopamine are treatments. Poisoned individuals become relatively asymptomatic within 24 hours of their ingestion. No long-term symptoms have been reported.

As with most all toxic plants, they have medicinal properties as well. The death camas root can reduce swollen knees and leg aches. Use with caution!!

Mountain Lions Are Keystone Providers for Birds!

When we think about World Migratory Bird Day, we often think about providing for their needs with water, bird feeders, and native plants, and hopefully we are keeping cats indoors and taking steps to prevent the lethal danger of window-collisions. We may even think about the importance of sponge city landscaping and beaver dams to slow and store snowmelt runoff, but it is the Mountain Lion which has the unique distinction of being a keystone provider ranked as the top vertebrate feeder of birds – in fact they “feed more mammals and birds than any other predator, increasing the number of animal interactions – the links in food webs so essential to maintaining ecosystem resilience. And they are ecosystem engineers on top of this as well.”
(1) Researchers have found that large carcasses create essential habitat for carrion-dependent beetles – these are not just food for beetles, but the very places beetles spend their lives, hiding from predators, seeking mates, raising young, and morphing from larvae [lahr-vee] into adult forms which disperse in search of the next carcass to begin the cycle all over again. (2)The food web gets to the very heart of bird migration, and the very real challenge of ensuring a future in which people and birds can thrive with dwindling habitat resources essential for survival.

Consider the Yellow-billed Cuckoo [koo-koo], one of the World Migratory Bird Day Ambassador species, to highlight the importance of water and riparian habitat for birds. A long-distance migrant, the Yellow-billed Cuckoo breeds in the United States, Mexico, and the Caribbean, and migrates through Central America to reach its wintering grounds in South America. It seeks wooded habitats with water nearby, where it feasts mostly on insects, especially caterpillars, during the spring and summer, transitioning to a more fruit- and seed-heavy diet in the fall and winter.

The Yellow-billed Cuckoo was selected for this year’s World Migratory Bird Day campaign to help shed light on the decline of riparian habitats along our rivers, streams, and freshwater lakes, particularly in the American West, where species that rely on these areas are experiencing population declines and are in possible danger of extirpation from some states. These western riparian species include Summer Tanager, Yellow Warbler, Willow Flycatcher, Yellow-breasted Chat, and Yellow-billed Cuckoo. Loss of native forest to farmland, housing, and other development has led to significant population declines in these species, especially in the case of the Cuckoo, which relies on large patches of streamside forest for breeding.

The Yellow-billed Cuckoo is becoming an increasingly rare bird in the American West. We need to increase awareness and encourage decision makers to explore ways to protect riparian areas, remove invasive species, restore habitat, and conserve water. World Migratory Bird Day 2023 aims to contribute to these efforts by highlighting the importance of water conservation and habitat management for migratory birds, and by providing resources to help promote these important issues. Bird Day is every day, but especially mid-May and mid-October. Learn more at migratorybirdday.org, and learn more about how to conserve water for sustaining bird life!

“In research recently published in the prestigious journal, Oecologia, we show that mountain lions are ecosystem engineers that create essential habitat for carrion-dependent beetles. It is the first research to show that an apex predator plays the role of engineer. In collaboration with graduate researcher, Josh Barry, and Dr. Melissa Grigione at Pace University, we collected and identified 24, 209 beetles across 18 sites, representing 215 unique beetle species. The carcasses abandoned by mountain lions were not just food for beetles, but the very places beetles spent their lives, hiding from predators, seeking mates, raising young, and morphing from larvae into adult forms that dispersed in search of the next carcass to begin the cycle all over again.”
