I remember my father on wintery Saturdays mounting his fly tying vice on the kitchen table, and then, from the cavern under the stairs, he’d emerge with his hooks, pheasant and peacock feathers, and other magical threads. I’d watch him spin intricate flies but never realized as a child that they were imitations of creatures I would meet and teach in the wild. When he took me to lakes and rivers to fish, we just used worms and pink marshmallows.

On an animal adaptation learning journey at Wood Camp along the Logan River this fall, our Edith Bowen Laboratory School first graders turned over river rocks, sweeping up all sorts of aquatic critters with nets and buckets to then probe playfully with tweezers and bare fingers. Trip Armstrong, Assistant Director of the National Aquatic Monitoring Center at Utah State University’s Department of Watershed Sciences, led our young investigators and several adult volunteers in identifying these benthic macroinvertebrates, especially the stonefly nymphs we found in every scoop.

These especially intrigued the children because they resemble something from outer space scurrying about on six legs. Stoneflies, both the nymphs and the adult insects, are large compared to mayfly and other critters you find in a river sample, so they stand out in a crowd. The adults have long wings, thus the Greek name Plecoptera meaning “braided wings,” but they are known to be poor fliers. The larvae have two tails or what biologists call cerci, while mayflies have three. Stoneflies have two hooks on their legs; mayflies have one. Stoneflies like oxygen-rich water flowing through their gills along their thorax and under their legs. We noticed some doing push-ups in the bin of river water, indicating it was time to return them to their habitat. Both mayfly and stonefly nymphs are pollution-sensitive, so finding them in such large numbers indicated that this part of the river was very healthy.

When a student approached from the river’s edge with a larger specimen cupped in her hands, I was stunned and a little spooked. “It’s a sculpin,” Armstrong said. These are bottom-dwelling fish that some say are basically big mouths with tails and have unflattering nicknames like “double uglies,” yet I learned later they are quite common. I’d just never met one. In fact, although biologists have determined that the Utah Lake sculpin has been extinct since the 1930s, the native Bear Lake sculpin and sculpin living in the Logan River are sources of food for the Bonneville Cutthroat and other trout.

I guess the lesson, as a wise first grader reminded me this week during our opinion writing session, is “Don’t yuck somebody’s yum.” Stoneflies and sculpin: flyfishers and bigger fish love them. I’m thankful for opportunities to teach in Utah’s wild places because every time I do, I learn something new.

Intelligent Tree Squirrels

Intelligent Squirrels: Squirrel Courtesy Pixabay — Squirrel

Primates of the northlands. I consider tree squirrels to be on par with many primates for intelligence and agility. Those who have bird feeders may agree with me as they vainly attempt to thwart squirrel’s from invading their feeders. We have red squirrels visiting our bird feeder regularly. I’ve outsmarted them for the moment, but they continue to work on the problem I’ve presented them and feel a failure coming my way!

I’ve watched red squirrels manipulate fir cones with their front paws with amazing dexterity. Like myself eating a cob of corn, it spun the cone rapidly while shredding the cone scales to access the seed. Their tiny toes grip the cone identically to my fingers gripping the cob of corn. I’m amazed how they can unerringly navigate their way from tree to tree through our forest. There are many examples of squirrel intelligence witnessed by animal behaviorists.

Arboreal squirrels often build dreys that look like bird nests. Dreys are made up of twigs , moss, feathers and grass. All the items surrounding the dreys provide support and insulation. Chimpanzees exhibit very similar behavior.

Squirrels make use of several vocalizations to communicate with each other, they also create scents to attract opposite sex or communicate. They can create signals with their tails as well, by twitching it to alert other squirrels on the presence of a potential danger.

Tree squirrels display fantastically acrobatic movements, phenomenal adaptability to urban environments, and possess very cute little faces to boot. The 7th International Colloquium on Arboreal Squirrels was held 2018 in Helsinki, Finland. Studies routinely come discover new, amazing behaviors, especially involving the squirrel’s signature behavior, that it buries caches of its food to access later. One experiment found that they’ll try multiple tactics to open a locked box. Another found that squirrels remember the location of their caches without using their keen noses to locate them. Another found that they’re able to quickly learn from their peers.

A 2010 study found that squirrels actually engage in deceptive, or paranoid, behavior. When squirrels are being watched, they’ll construct fake caches, pretending to bury a nut by digging a hole, patting it down with their front teeth, and scraping dirt or grass over the top of it while concealing the nut in a pocket near their armpit, and will make the real cache somewhere else. Even while watching, it can be difficult to tell when a squirrel is making a fake or a real cache. How smart is that?

A study was conducted at UC Berkley in which students were placed in a competitive game to act like squirrels. They hid caches of plastic eggs, and then 15 minutes later returned to find them. This is a very squirrel-like test: memory, deception, location, observation, paranoia. Most students couldn’t remember their own hiding places. Squirrels bury about 10,000 nuts per year, making many different caches, and may not uncover them for months. They may dig up a cache and bury it somewhere else, and do that up to five times. Squirrels, unlike UC Berkeley students, are engaged in this intellectually draining activity while also avoiding predators and braving the elements.

Ripple Effects: Enhance Backyard Birdwatching When You Feed & Protect Birds

Birdwatching is a fun hobby for all ages and it is a great way to connect with nature and increase self-efficacy, so let’s discuss the benefits and the importance of a safe environment for feeding our backyard birds. First, the benefits of supplemental feeding, and second, preventable deaths from cats and window collisions.

Supplemental food and water are important ways we can reduce stress for backyard birds, especially through the winter months. Sites with bird feeders attract more birds over time than those without feeders, and the birds are in overall greater health than birds at sites without feeders. A higher percentage of chicks hatch at sites with bird feeders, and the survival rates are significantly higher, but supplemental feeding must be done in a safe environment.

Free ranging domestic cats and window collisions are leading causes of bird deaths in North America. The American Bird Conservancy estimates that outdoor cats kill approximately 2.4 billion birds every year in the United States alone. Approximately one billion birds are dying from window collisions each year in North America – that represents about ten percent of our birds dying from crashing into windows (1), and combined, that’s over three billion fewer insect eaters, fewer pollinators, fewer seed spreaders, and fewer parents for the next generation.

Cats should be kept indoors, and windows should be treated, especially if they reflect trees and shrubs. If you have seen a ghostly bird imprint or heard the sickening thump of a bird hitting your windows, then those are windows in need of treatments such as screens, translucent UV tape, or even tempera paint designs, because even birds that manage to fly away have potentially life-threatening internal injuries. Feeders less than 3 feet away don’t allow birds to build up too much speed before they collide, so it’s good to put feeders and birdbaths 3 feet or closer to a window or greater than 30 feet away.

Feeders placed on or near windows have the added benefit of being easy to access and monitor. In addition to a window suet feeder, one of my favorite window feeders is actually a clear plastic suction-cup toothbrush cup holder from the dollar store – it’s easy to clean and there’s no need for binoculars!

In addition to enhancing a backyard bird watching hobby and improving bird health and survival, the ripple effects of feeding birds, keeping cats indoors, and preventing window collisions include pest control in our gardens where birds feast on slugs, snails, aphids and grasshoppers. I for one particularly appreciate Black-billed Magpies when they remove wasp nests from my house! The Bridgerland Audubon website has tools, coloring pages, checklists, and science-based information on window collision prevention. Solutions can be as simple as the careful placement of bird feeders and keeping cats indoors. Find us at bridgerlandaudubon.org, that’s Bridgerland Audubon – A-U-D-U-B-O-N dot org.

The berry season is upon us- huckleberries, raspberries, gooseberries, chokecherries (not a berry but close enough), elderberries, bearberries, while early berries have faded- golden current, serviceberries, thimble berries are now fruit leather.

Berry picking during my youth in the North woods of Wisconsin was a wonderful tradition that I, and our black bear neighbors, looked forward to with great anticipation. We often shared the same patch evident by fresh bear scat and tracks. Those rare occasions where brother and sister bear were with us are frozen in time. “Just keep picking and talking- they won’t bother us.” My grandmother’s refrain. I was enthralled, watching every move and sound they made, with an occasional “woof” from mother bear alerting the youngsters.

Now, so many years later, I take my students to the Tetons hoping for a glimpse of bruins harvesting berries, rose hips, and thorn apples along streams and roadsides. Black bears are efficient berry-eaters, consuming up to 30,000 berries a day in a good year. They gather berries quickly, using their sensitive, mobile lips swallowing them whole. The berries enter a two-part stomach, which grinds the pulp off the seeds which pass through unbroken and are able to germinate, making black bears important seed dispersers.

Our Bear River Range here in Northern Utah was once a stronghold for the bruin. Overharvesting by hunters and the government has left it wanting, but the berries remain. One berry favored by bears is the white snowberry. Don’t copy the bears on this one as it’s toxic, but a great medicinal. Another that I avoid is the buffalo berry, called soapberry in the northwest. It contains saponin, the active ingredient in most soaps. It’s much like biting into a bar of soap, applied in my younger years for mouth cleansing. And please avoid the voluptuous red and white fruit of the bane berry, and cute little mini tomatoes of deadly night shade. You will be all the better for it.

“Harvesting berries can be a powerful meditation, centering us in the power of “now,” and is one of the oldest human experiences. This simple action can be an opportunity to revel in the abundance of nature. Tangibly interacting with food that is so wired into its life source is otherworldly, and it reminds us of a time when humans were more directly connected to the origins of our food. It is a grounding experience that demands every cell in your body resonate with the source of our food, catalyzing our connections to the universe.” Valerie Segrest quote

I strongly recommend “Blueberries for Sal” for younger generations. A delightful 1948 children’s book by renowned author Robert McCloskey. I recently visited the Blueberry Hill in Main’s Acadian N.P., the location for this story, and picked a few myself. Unfortunately, the bears had been replaced swarms of tourists!
