On December 14th, I will join several others for an exciting day of counting bird species and numbers in our lovely, snowy valley. The numbers will be entered on a database that will be shared globally.

Count Data:
The data collected by observers over the past 120 years has allowed researchers to study the long-term health and status of bird populations across North America. When combined with other surveys such as the Breeding Bird Survey, it provides a picture of how the continent’s bird populations have changed in time and space. This long term perspective is vital for conservationists. It informs strategists to better protect birds and their habitat, and helps identify environmental issues, with implications for people as well.

The count has special significance for our changing climate’s impact on birds which is disrupting populations and their spacial distribution that are changing at an accelerating rate.

The report:
Audubon’s 2014 Climate Change Report is a comprehensive, first-of-its kind study that predicts how climate change could affect the ranges of 588 North American birds. Of the bird species studied, more than half are likely to be in trouble. The models indicate that 314 species will lose more than half of their current range by 2080. Adding to this, a recent study by the Cornell Laboratory of Ornithology reported a 29 percent decline in North American bird populations since 1970.

142 species of concern are found in Utah including our state bird, the California gull and our national symbol, the bald eagle. Averaging the most recent 10 years, Cache valley has seen 16 species increase and 11 species decline. Of course we would need a much broader sweep to know the true story of these species, but our data may play a significant part in the overall analysis.

Audubon’s Climate Initiative, encourages its members to take steps to address the climate change threat in their backyards and communities. Visit their website at audubon.org for how to take action.

Many Citizen Science programs exist for families to participate in- https://www.birds.cornell.edu that have generated reams of data over many years showing the species diversity and abundance of birds in North America and globally. Our valley Christmas Bird Count occurs next Saturday, December 14th. Contact bridgerlandaudubon.org for details. Always a good time gathering important data!

And please, keep those bird feeders full as we enter the coldest month of the year!

The Ecology in and around the Logan River

Logan River ecology is about connections between highlands and lowlands, water and land, life in and around the river and resources that support that life.

The river begins in southeastern Idaho and runs 53.5 miles to its confluence with the Cutler Reservoir in Utah’s Cache Valley. The river transitions from mountain riparian, characterized by low growing willows and coniferous trees, to the valley’s lowland riparian where it’s dominated by a variety of shrubs, cottonwoods, and willow trees. Both wildlife and plants change along this elevational gradient giving the Logan River greater ecological diversity than might be found over hundreds of miles of a flatland river.

Rivers move water. They also transport sediments and nutrients that drop out of the water wherever the current slows, for example on floodplains during spring floods. This is why floodplains, or riparian zones, have such productive soils.

The rich soils and water available on the floodplain support a wide diversity of plants. These plants in turn provide underlying layers for insects, nesting sites for birds, and water-cooling shade that harbors the heat sensitive cutthroat trout. Plants also drop their leaves into the river providing food and nutrients to aquatic insects.

One insect found in the Logan River is the mayfly, a graceful macroinvertebrate with unique upright wings and a delicate silhouette. The female adult drops her eggs on the river’s surface which then fall to the river’s bottom. The nymphs hatch within a few days or weeks. They spend the next year moving along the river’s bottom hiding among vegetation, rocks, and fallen leaves. After a year, nymphs swim to the surface and molt into duns which fly to nearby riparian vegetation. After a couple hours duns shed their skins and become brightly colored adult mayflies called spinners.

Male spinners form a swarm over the water to attract females who fly into the swarm. Pairs mate in flight; after mating the female flies down to the river to deposit her eggs, and dies shortly thereafter.

A large number of mayflies do not complete their life cycle as they are eaten by fish, spiders, bats and birds.

Bonneville cutthroat trout, Utah’s state fish, subsist largely on aquatic insects including mayflies. Feared to be extinct in the 1970s, biologists searched the state for Bonneville cutthroat trout and when a population was found in the Logan River, wildlife managers and USU scientists teamed together to ensure the cutthroat population became and remained robust.

Hundreds of bird species eat aquatic insects; one bird, however, specializes in eating aquatic insects under water. The American Dipper, walks on the bottom of Logan River using its wings like a submarine’s diving planes to keep it from bobbing to the surface. Walking along the river bed, the dipper turns over small rocks and sunken sticks to uncover and eat insect nymphs.

Other riparian birds, like the belted kingfisher, are fish-eaters. This handsome, crested, steel blue bird can be seen perched in the trees next to the Logan River eying fish beneath the surface. At times, kingfishers will hover directly above the water announcing their presence with a loud, rattling call. At the right time, the kingfisher dives headlong into the river using its long, sharp beak like a tweezers to catch small fish.

Rivers, like the Logan, and their riparian zones, support some of the richest biological diversity in the West. They are forceful and ever-changing, but provide all that life needs to survive and thrive in a compact area. These are dynamic ribbons of green and blue that connect land to water, plants to animals, and humans to nature.

Winter Songs

Most of our songbirds have taken their songs and headed south. Even robins and meadowlarks have ceased their lovely melodies that carried well into the fall months. But there are a few noteworthy choristers that have remained- Townsend solitaires and N. American dippers. Not only do they sing beautifully (anthropocizing here) but they vocalize for different reasons than most. The breeding/nesting season has long since passed, which is the primary reason birds sing- attracting a mate and defending their breeding territory from other males.

So one might ask why sing? Both of the species mentioned are defending their feeding, not breeding territory. Townsends switch from insects to berries during the winter months, including juniper berries (actually cones) which they have a special penchant for. I’ve witnessed many instances of them doing battle while defending their tree from intruders. They often perch on the highest branch daring others of their kind to pick a berry. Females defend as well.

In my cozy little canyon they begin migrating down from their high mountain nesting territory in October filled with song, which is supposedly different from that used during courtship. Townsends keep good company as members of the thrush family which include bluebirds, robins, and various other thrush species- all known for their enchanting refrains. A flock of thrushes is known as a hermitage, interesting considering there is one named hermit thrush, quite common in our mountains.

Robins, also berry eaters, are welcome guests, and often share the same tree with the solitaires. Considerably larger than their cousins, they feed unmolested.

The dipper sings its river song as it flits along streams. The varied notes are complicated and loud, possibly to compete with the rushing waters where it resides, including water falls. They will lay claim to a stretch of stream and like the solitaire, daring another of its kind to trespass. I’ve witnessed this amazing songster singing full tilt during white-out blizzards, challenging the storms intensity with its brazen refrains. “The dippers song is strong and sweet, made up of a great variety of trills and flute-like passages, delivered with great spirit and brilliance.”

I’ve not attempted to measure the length of its feeding domain, but assume it varies depending on food abundance. This little “penguin of the Rockies” as I call it, will dive underwater using its wings to stroke along the stream bottom while capturing its prey, which may include small fish. Constant preening with oil from near the base of its tail keeps it dry, and high density feathers provide excellent insulation. The cold waters must bring relief from comparatively frigid winter air.

I once observed a most unusual mating behavior when a pair of lovers suddenly spiraled up well over a hundred vertical feet from the stream, where they are otherwise tethered. Is this usual during courtship? I’ve only seen in on one occasion. Nature is full of mysteries and shock factor. Never say never! The Audubon Climate/bird reports Solitaires lose 92% of their summer range and an 88% loss for dippers by 2080, and their songs as well. This means more miles on my bike and less in my car.

Why I Teach Outside

In February of this year, researchers published an integrative review of the literature on nature’s role as a catalyst for academic growth in children. They had this to say about their findings: “In academic contexts, nature-based instruction outperforms traditional instruction. The evidence here is particularly strong…” (Kuo, Barnes, and Jordan, 2019). For a long time, great thinkers such as renowned educator John Dewey and conservationist Aldo Leopold have recognized and professed the power of situational, hands-on learning—especially in the natural world, and especially among children. This sentiment is something we all share, I think—something bordering on instinct. Now, scientific research has caught up to a truth we all know in our bones.

This is a topic close to my heart; I’m a third grade teacher who got his start leading groups of kids into the backcountry, canoeing and backpacking the lake-littered northern latitudes of the mid-west. Adventure and education always seemed necessarily intertwined to me. “Education is not preparation for life,” said John Dewey; “education is life itself.” And life, I’ve always thought, is out there. The authors of the literature review agree, writing that “experiences with nature…promote children’s academic learning and seem to promote children’s development as persons” (Kuo et al., 2019). One of the key logs for this increase in learning and development is the increase in students’ motivation once they’ve left the walls and classrooms behind. According to the researchers’ report, “learning in and around nature is associated with intrinsic motivation, which, unlike extrinsic motivation, is crucial for student engagement and longevity of interest in learning” (Kuo et al., 2019). Even more “[e]ncouragingly, learning in nature may improve motivation most in those students who are least motivated in traditional classrooms” (Kuo et al., 2019).

I’ve been fortunate to have had the opportunity to work with students in the field. While out there, I’ve had that instinctual knowledge we all share reaffirmed while sitting next to a dammed-up beaver pond, watching third-graders reverse engineer the beaver dam out of rocks, sticks, silly putty, and freshly-chewed wood chips from a beaver log. I know my circumstances are not the norm, though—not yet, at least. So, how might teachers utilize the natural world when there’s no beaver dam on campus and they can’t get the funding or administrative support to go find one? It may be simpler than one thinks! There is an abundance of evidence that indicates students can reap the same benefits just from being outside while they learn. “In multiple studies,” the researchers point out, “the greener a school’s surroundings, the better its standardized test performance—even after accounting for poverty and other factors—and classrooms with green views yield similar findings” (Kuo et al., 2019). To supplement the views and the greenspaces, though, teachers can consult research-based resources like UC Berkley’s teaching guide, School Yard Ecology, and the National Science Teachers Association’s inspired 10-minute Field Trips.

If the increasingly robust academic research into nature’s role in student learning is any indication, though, I foresee a not-so-distant future replete with an even wider diversity of resources and opportunities for teachers and students to explore the natural world in pursuit of academic rigor. “It is time,” the authors of the integrative review write, “to bring nature and nature-based pedagogy into formal education—to expand existing, isolated efforts into increasingly mainstream practices” (Kuo et al., 2019). It seems incumbent upon us to trust the truth we feel in our bones.
