These big cats have over 40 names. (Courtesy NYPL free digital file.)
Early one December evening a neighbor was driving home near our home when she spotted movement out of the corner of her eye. Thinking a deer was about to dart in front of her car, she immediately stopped to prevent a collision. She was astounded when a mountain lion crossed about ten feet in front of her illuminated by headlights.
A mountain lion………in Iowa! Perhaps that’s not so farfetched. Our neighbor would know one when she saw it.
Mountain lions (Puma concolor) are spreading out from their traditional home in western mountains. A couple of decades ago the only known eastern population of the big cats was in Florida, where they are extremely rare and are usually called panthers. These big cats were once common throughout North America except for the far north. They also ranged throughout all of Central and most of South America. As big predators they were heavily persecuted by humans, and their habitat was devastated by settlement. A big blow to cougars was the elimination of deer from much of their range in the late 1800’s.
Much has changed to give lions, or cougars as they are sometimes called, an opportunity to expand.
Most people now appreciate them as beautiful animals and don’t shoot them on sight. Many states protect them from shooting. Also, the woods and deer have returned. In 1900 most of what today is a vast hardwood forest that stretches from the Mississippi River to the Atlantic Ocean was farmed. Many of those farms went out of business and trees move in. Today, there’s near continuous forest for hundreds of miles and much of it is filled with deer, a favorite food of mountain lions.
A few years ago a male cougar walked from his Black Hills home to Connecticut, where he was hit and killed by a car. Most Midwest states have documented the presence of cougars. A few have been hit by cars. More have been photographed by trail cameras put out by hunters to track deer movement. Some have been shot. Seeing a live one is very rare.
So, a cougar sighting near Winding Pathways in Iowa is neither impossible nor surprising. It was probably a young male cat seeking a mate and place to live.
Do mountain lions pose a threat to people, livestock, or pets? Not really. There have been documented cougar attacks on people, mostly in California where they are not hunted and have lost fear of people, but the risk in most places is trivial. Cougars are shy animals that choose to stay out of sight and prefer eating deer to dogs, sheep, cattle, and cats.
We wish we’d seen the mountain lion that passed through our neighborhood but he’s probably miles away by now.

Almost all substances contract as they get colder. There’s one notable exception and it enables life.
Ice expands and floats
As water cools, it gets denser. As the temperature continues to drop, cold surface water sinks to the bottom. When the lake’s surface water reaches 39 degrees Fahrenheit something amazing happens. As weather continues to get colder it expands. When it turns to ice it expands even more! That’s why ice floats. If it didn’t, ponds and lakes would completely freeze and nothing could live in a solid block of ice.
Ice floating on a lake moderates the temperature of the water beneath it. Although the air temperature may be below zero above the ice the water beneath it is never below freezing. That’s why fish, frogs, and other aquatic organisms can not only live but also bask in the relative warmth of the water while terrestrial animals are forced to survive in arctic cold.
This phenomenon makes ice fishing possible. The following blog was written by a friend who took her children fishing one cold morning.
Ice Fishing With Kids
Story and photos of people
by: Kelly Carr
“They weren’t budging. Even with the overhead light flipped on, gentle shoulder shakes, and promises of the fun they would have, my kids feigned sleep. It was 7:00 a.m. on New Year’s Eve, and it had been about a year since our last ice fishing attempt. This particular day was the sixth of a seven day stretch of the new shared-custody arrangement I had with my daughter and son’s father. As if putting them through a divorce wasn’t guilt-inducing enough, now I was trying to drag them out of the security of their warm beds. My mind drifted back to the present – if I could just get them going, I knew they would have a great time. So, I played the “Let’s Get Donuts On The Way” card. Sleeping forms shifted, eyelids sprung open. We were out the door in fifteen minutes, teeth unbrushed, bedhead tucked under stocking caps, and feet snuggled into a double layer of socks.”
Donut Bribery works!
“I’ve tried to raise kids who feel comfortable in nature. Driving to the park for the ice fishing clinic, the car filled with the smell of maple frosting. I mused silently upon some of our past outdoor adventures. We have been geocaching newbies, tramping at a roadside park, looking for a “small bison container”, which, as it turned out, was NOT a buffalo figurine after all! We’ve packed picnics into cemeteries, and talked oaks and stones and stories while we ate.
“A voice from behind jostled me back to the present. I passed a cappuccino to waiting hands in the backseat and then pointed up to a hillside, “Look – a cemetery!” My daughter protested, “Not today, Mom! Ugh!” You win some, you lose some.
The Outdoor Thing
“We wound through the park to the shore. After a quick presentation by a naturalist and distribution of fishing guides, bait and poles, we were set. My kids chose spots not too far away from their last year’s spots, got settled in on mats and sipped from their gas station cups while waiting for spring-bobbers to bob. The sun made things sparkle, and as I looked at them handling things and sitting in peace, I knew I had nothing to feel guilty about. Tummies full, bundled in warm layers, taking a chance on adventure, we were doing this “outdoors thing”. And we were finding our new “normal” while doing it. They each pulled two fish out of the water that morning before asking to go back to the car to listen to music. I consider that as success.
Smiles
A warm bed is no match for the coolness of catching a panfish in winter.
“I had a few moments to myself out on the ice, to take it all in. Even when life changes, there are constants we can count on. The fish may not always bite, but while the sky is above and the earth (or ice) is below, I am a mother who loves her kids.”

Sometimes change happens as quickly as flipping a light switch. One moment it’s dark. A second later brightness fills the room. Other changes creep up so subtly that it’s hard to notice them at all.
That’s what happened to my hearing acuity. It probably started years ago when massive machine gun noise assaulted my ears during Army training, and running chain saws, lawn mowers, and other machines didn’t help. Gradually and pretty much unnoticed I developed tinnitus and lost the ability to hear many of nature’s delightful sounds.
Rich could not hear the sweet sound of the finch.
One day my wife, Marion, and I were sitting in the living room when she asked, “What bird is calling outside the window?” I couldn’t hear a thing! It was time to get my hearing checked and a few days later I was at Heartland Hearing Center in Cedar Rapids. Audiologist Jennifer Reekers positioned me into a small booth and tested my ability to hear sounds of varied intensity and wavelength. The test proved what I already knew. I could not hear many sounds well, especially high pitches.
“Hearing aids will help restore your ability to hear many sounds,” she said. Over the next few weeks, she fitted me with a different trial pairs until I found one that did the trick. It was in spring and I could hear bird calls I hadn’t heard in years. Some sounds were odd, like hearing my own footsteps and my pants legs swooshing together as I walked.
My experience with the aids has been positive and, although they were expensive, it was money well spent. In the Premier section below is an article on the causes of hearing loss and how to improve hearing. It includes tips to protect hearing before loss sets in and what can be done to enable better sound detection and is reprinted from OUTDOORS UNLIMITED Magazine.
Wildlife and Hearing
Humans are fortunate. We have a fair ability to see, hear, taste, and smell. The senses of many wild animals have senses much better than ours, but they usually aren’t as well balanced.
Barn owls can find prey in complete darkness using only their hearing.
For example, according to Karla Bloem, Executive Director of the International Owl Center, a barn owl’s hearing is so keen that it can detect and catch a mouse in complete darkness. Its vision is also outstanding, although probably only in black and white. But, that owl may not have a sense of smell or taste at all.
Like owls, wild turkeys have outstanding vision and hearing but probably no sense of smell or taste.
The sense of smell and hearing possessed by deer is amazingly well developed, but their vision isn’t very good. Humans are fortunate to have all our senses, although none of them may be as keen as those of certain animals. Hearing loss can often be prevented. Take care around loud noise.

“As the gunner fired bursts, my hands guided belted ammo into the big Browning machine gun. The noise was so intense that concussions jarred my skull.
“Military noise, augmented by youthful years in small planes, running power saws, and hunting eventually caught up with me. By my 40th birthday my ears started buzzing. Called tinnitus, noisy ringing has been part of my life for decades.
Children’s voices were lost to Rich.
“Gradually it became harder to hear some sounds, especially the high pitch speech of girls. Conversing in a crowd became maddening as I could hear background conversation but not the person in front of me. Eventually wood thrushes and my wife’s expressed concerns convinced me to shun procrastination and seek help. No sound in nature is as magical as the springtime notes of this woodland bird. Several years ago I heard my last thrush. Either they were absent from the woods or my progressive hearing loss blocked their music.
“Studies link hearing loss with depression, dementia, falling, high blood pressure and anxiety but, it was the inability to hear birdsong that launched my search for a solution. I’m not alone. At least one in three people, men and women alike, over age 60 suffer hearing loss. Unfortunately many fail to seek solution.
“Hearing loss is nondiscriminatory. Cumulative noise exposure impacts people of all ages and both genders. A current concern is high volume music from ear buds. As many as a fifth of teenagers may eventually suffer hearing loss from it.
“Advertisers know this, and when my 60th birthday passed I began getting bombarded with hearing aid ads. Some claimed cures for tinnitus and most offered better hearing at bargain prices. Most sounded too good to be true. I decided to seek a certified audiologist and within a week was sitting in a quiet booth as Jennifer Reekers of Heartland Hearing Center tested my ability to hear. It yielded no surprises but was disconcerting. I couldn’t hear high pitches.
“Jennifer holds a doctorate in audiology. She and her business partner, audiologist Diana Kain, patiently answered questions and convinced me that I was not just about to buy hearing aids but was beginning a long term relationship with professionals committed to improving my hearing. They fitted me with a trial pair of hearing aids appropriate for my non-typical lifestyle.
“Usually I work at my computer a few hours, then run a power saw, then back to the computer, then target practice with my .22 rifle. I’m outside in wind, rain, blizzards and other quirks of nature. Sometimes I need to amplify sound then suppress a saw’s roar or a rifle’s bark.
“Jennifer used marvelous technology to adjust the aids to fit my needs. They aren’t merely amplifiers. They are computers enabling aids to fit varied needs. Jennifer manipulated her computer while tuning my aids to dampen tinnitus and background noise while boosting my ability to hear high pitch sounds.
” The following day I hiked seven miles in Effigy Mounds National Monument amid calling orioles. As I sat on a bluff over the Mississippi the delightful song of a wood thrush filled my ears.
“An important feature of my new aids is a tiny mute button. Just before I pick up my power saw or .22, I mute the aids and slip quality muffs over them. The mute function eliminates the hassle of removing hearing aids before noise exposure.
Hearing and locating birds got easier with hearing aids.
“I spent a week trying everything I could think of to frustrate the new hearing aids before I decided to buy them. I went out in the rain and wind and even evicted a black fly that had crawled into my ear. The aids stayed in place and kept working. I couldn’t shake them out. They were comfortable, even after 14 hours and amazed me. One afternoon I rowed to the middle of a smallish lake and could clearly hear bank anglers conversing.
“Expensive! Yes, but being able to hear a thrush and converse with the neighbor kids is priceless. The cost didn’t just buy hearing aids. It established a relationship with the audiologists who are my hearing coaches. I can access them at any time at no additional cost. They’ll tune and clean the aids as the need arises.
“Licensed professional audiologists have a higher degree of training than hearing instrument specialists or hearing aid salespeople and have access to a wide array of hearing aids. Jennifer and Diana have helped me recapture my hearing and their peers can likely help many of the millions of Americans who suffer hearing loss.
PREVENTING HEARING LOSS
“Hearing loss is a stealth condition. Exposure to loud noise is cumulative and gradually permanently degrades hearing. It is the root cause of tinnitus. Correction is outstanding for those of us with hearing problems but prevention is far better. Loud music, lawnmowers, saws, blenders and vacuum cleaners, and especially firearms cause hearing loss that can be prevented.
” Here are recommendations from Audiologists Reekers and Kain:
- Keep the volume down. Teenagers wearing earbuds that channel high intensity music into their ears are preparing for future hearing loss.
- Wear hearing protection whenever exposed to loud noise. Put on the muffs or plugs, even when running the lawn mower or vacuum cleaner.
- Protect children from loud noises.
- When target shooting it’s a good idea to wear both ear plugs and muffs at the same time to further dampen noise. Suppressors help reduce noise but wearing muffs remains prudent.
- Don’t procrastinate. If hearing problems develop find a licensed audiologist!
