It has been a very long time since I have contributed to my natural history blog – more than a year has passed. Depression is a force that puts a writer down…
Ever since the January, 2025 election, I have been horrified at what has been happening in our country. My faith in my fellow man and my hope for our collective futures has been deeply eroded. Our nation has become more and more divided; a dangerous path to follow. Within the five-word title of our country, there is one word that means far more than all the others; that word is “United.” National unison is the bedrock of this nation, the fundamental core of its history, and essential to its future.
Throughout this unfolding saga, the country’s focus has been decidedly political, diverting our attentions away from the stunning amount of damage that our national leader and his entourage of sycophants have inflicted on wild lands, wildlife protection laws, and wildlife habitats.
Considering that my life’s work has centered around teaching natural history and the protection of wild lands, and that I have a love and appreciation for my country and its democratic ideals, it is no wonder that I have not been in the requisite mood to write much of anything during the past year.
Lately, however, my mood has been steadily improving. Americans are raising their voices, peacefully and actively resisting that which is fundamentally wrong. On a local level, my spirit has been lifted by the sight of a lush emergence of brilliant green grasses and other understory plants that have sprung to vivid life in our mesquite bosque and all across the valley. A return of the normal winter rains has enabled this welcome change on the land. After more than a year of drought, the surge of new growth warms my heart and mind.
In what follows, I offer a photographic and written glimpse into some of the past year’s wild happenings. The land, the plants, and the animals depicted are a reminder that the limitless beauty and wonder of the natural world is still there – to heal, inspire, and bring light to our spirits…
In late summer, I awoke early one morning to find these paint-fresh tracks of an adult black bear that had stepped over my entry steps and walked beneath my ramada, leaving its signature tracks in fine-grained, dry soil. 2025 was my best year yet for seeing Gila monsters in the wild – a total of seven sightings, five of which occurred here within our velvet mesquite bosque. This is one of those lizards, a creature that spends the great majority of its lifetime below ground, out of sight. I was lucky enough to witness this seldom-seen event for a second time last summer, when I came upon this pair of large male western diamondbacks dueling behind our shop building. Their elegant dance went on for hours. Later, I looked for and found the victor, curled up with a female rattlesnake. The two males had been following her scent trail, resulting in a meeting that quickly morphed into a struggle for mating rights. For more info. on this behavior and more images, have a look at the previous blog, accessed via this address: https://ralphwaldt.com More than twenty years had elapsed before my wife and I saw a coati on our property. We had found their tracks many times, but had never seen one here until this big bruiser of a male showed up last month. He stayed for several days after discovering a taste for the bird seed that Kathleen spreads on the ground every morning. Note the thick, winter-furred tail and the very well-developed front and hind quarters of this impressive old male. Unlike most coatis, we never saw this animal walk with its tail raised vertically in lemur fashion. I wonder if this has something to with expressing his place in the society of these social mammals. Mature males commonly spend much of each year alone, as opposed to others of their species. Photo by Kathleen Waldt. Coatis have long, flexible rostrums (a.k.a. “snouts”). Concealed within their long snouts is an intricate maze of paper-thin turbinate bones covered with an extensive network of nerves that enable the animal’s exceptional ability to smell – and thereby locate – much of their food. The powerful claws on their front feet did not evolve for fighting, nor for killing prey – they are for digging. Among the coatis that roam the Middle San Pedro Valley, digging for arthropod grubs and pupae furnishes these Sierra Madrean mammals with the bulk of their diets. Photo by Kathleen Waldt.
This huge moth fluttered by me like a bat-turned-insect one afternoon, landing upside down on the roof of my ramada. Its common name is “Black Witch Moth,” not what one would consider a flattering moniker. I did not perceive it in such a light; I saw a perfect expression of nature’s form and beauty, a creature whose wings were adorned with intricate artwork and remarkable camouflage. The less degrading name for this insect is, in technical terms, Ascalapha odorata. Autumn leaves falling from the cottonwoods that line the banks of the San Pedro River sometimes exhibit these fascinating patterns. They are the tracings of insect larvae collectively called “leaf miners.” Leaf mining is a type of behavior that involves larvae that live within a leaf, feeding on the inner tissues while leaving the epidermal (outer) layers of the leaf intact. This affords the larvae some measure of protection from predation. Leaf mining evolved in several different families of insects, including flies, beetles, and moths.
A quiet section of the San Pedro River in early November reflects an immaculate tapestry of form, light, and color, a place of quiet beauty that instills a sense peace, calm, and gratitude into its viewers.
Among the most incredibly adept fliers in the avian world are a group of hawks known as accipiters. This gorgeous Cooper’s hawk was photographed while drinking – and then bathing – in one of our bird watering dishes. I have watched these amazing hawks pursue birds (their most favored food) at breakneck speed into and through thick brush with the ease and finesse of a darting insect. Photo by Kathleen Waldt. On a broiling hot early summer day, Kathleen captured this image of an adult bobcat, standing some ten feet from our front doorway. Opening the inner door as slowly and quietly as she could, Kathleen photographed the cat through the screen door, giving the image a soft, pastel look. Among the four species of skunk that inhabit the San Pedro River Drainage, hooded skinks are the most common in the valley floor. Their lengthy and long-haired tails set them apart from the other three species. Yesterday morning, I had walked only a short distance out the door when I spotted something that was pure white at the base of a mesquite. Immediately, I thought of the tail of the hooded skunk that has been wandering our bosque almost every night for the past half year or so. Just as quickly, I realized that something wasn’t right, for the tail was entirely flat on the ground. Sure enough, it was the tail of our resident skunk, and all life had left its owner. Perched atop the body of the skunk was a great horned owl. Photo by Kathleen.
The signature plume of the skunk’s long, snow-white tail extends far beyond its predator. It is not uncommon for great horned owls to tackle prey as large and formidable as skunks and house cats. Photo by Kathleen.
The owl remained on the ground with its large meal all day long, alternating between bouts of feeding interspersed with naps. Most of the time, the bird stayed atop its prey, protecting its dinner by covering it from sight with a look that says, “I dare you!” An eruption of fresh, new growth, composed primarily of London rocket (Sisymbrium irio), and Mediterranean grass, (Schismus arabicus / barbatus), graces the mesquite forest with a verdant refulgence of color and life. Despite the fact that these understory plants are non-native, their presence shades the ground, conserving soil moisture, while providing a substantial infusion of organic matter that will help build and maintain the duff layer and enhance underlying spoil health. The vivid color of new, green plant growth has always fed my soul and never fails to paint smiles on my face.
Cherish and protect our common mother, the Earth.
Foster a deep respect and reverence for all life.
Show kindness, compassion, and respect for your fellow human beings, regardless of race, sex, language, political affiliations, or country.
Resist passing judgement on others.

The Middle San Pedro Valley sprawls across nearly one million acres of undeveloped, unfragmented land in southeastern Arizona. Its slopes and woodlands, bajadas and ridges have been rimed with frost every dawn under the abbreviated touch of winter’s Sun. Days are short. The land stands hushed and still with its seasonal absence of many birds, reptiles, and other forms of life. Nonetheless, there are many good reasons to get outside and walk the land. January and February have brought a few surprises, particularly in the way of unexpected sightings of locally uncommon birds.
In late January, five purple finches began frequenting our bird feeders, thinking they were well concealed within mobs of house finches and lesser goldfinches. My wife’s sharp eyes picked them out of the crowd. In 20+ years of avian record keeping in this valley, that was the first time we had ever seen purple finches. Another species that has been sighted sparingly here during the winter months is the American robin. For reasons that remain a mystery to me, we have been inundated with robins this winter. They bring me many fond memories of their near-constant presence during past summers when I lived in the northern states.
Speaking of thrushes, another bird that I had never seen in the valley before has arrived to grace the nearby riverbottom woodlands this winter – a Townsend’s solitaire. A friend and neighbor, Tom Talbott, first sighted one about a week ago in the forests along the river not far from our home. Tom is a highly skilled birder and a masterful wildlife photographer. A few days later, walking the same reaches of the river, a friend and I also saw a solitaire. News has been spreading of numerous sightings of this species in areas just a few dozen miles to the north.
A Townsend’s solitaire perches quietly in branches overhanging the channel of the San Pedro River. These elegant thrushes are common residents of timberline forests high in the mountains of western Montana, where I would meet them again and again as I led groups of hikers during the summer months. Their songs are unique and unforgettably angelic, like no other bird I have known. Photo courtesy of Tom Talbott.
Not far from the solitaire, we found this great horned owl snoozing within the branches of a Fremont cottonwood. These owls are remarkably capable predators whose list of possible food items exceeds that of any other North American owl. Among the creatures that great horned owls have been known to prey upon include insects, amphibians, various reptiles, mice, rabbits, domestic cats, small dogs, ducks, skunks, and even porcupines.
Mid-January brought us over an inch of rain in the valley floor during one winter storm. Rainfall amounts were much higher in the nearby Galiuro Mountains, resulting in a strong winter flow for Hot Springs Wash. Such flows during the winter months are rare.
The rain enabled millions of dormant London rocket (Sisymbrium irio) seeds to sprout, providing a new source of food for wildlife while greening the floor of this mesquite bosque with the glowing color of new life.
Large numbers of these small white puffballs erupted from the ground under mesquite trees after the rain. Fungi are becoming known as some of the most important organisms on the planet. The mycorrhizal filaments of many species of fungi form mutually beneficial associations with tree roots, for example. No forest on Earth can exist without such subsurface fungal alliances.
A hooded skunk wandered under my ramada one night, leaving its signature behind in the form of these tracks made in fine, dusty soil. Note the track pattern as the animal was walking at normal speed.
A closer look at the skunk’s footprints. Even though skunks are plantigrade mammals, the heels on their back feet often do not register in their tracks, as seen here. (The hind foot is to the left, front foot to the right.)
I discovered this torpid spiny lizard spending the winter brumating underneath a plastic tub that had been set outdoors on the ground. The lizard was found at ground level, not dug in below the frost line. Temperatures here routinely dip into the teens every winter. I was taught that reptiles must spend winters below the frost line, because otherwise they would freeze and die. I have also seen a pair of diamondback rattlesnakes spending the winter under a board in an open barn. Apparently, what I was taught cannot be correct – it seems clear that these reptiles can endure a fairly substantial amount of freezing.
Winter brings many changes to the activities of our local wildlife. Mule deer move into the mesquite bosques to feed and find shelter. Last year, a magnificent buck lived here, in the company of many does. On a late December afternoon, he stepped out into the light, his neck characteristically swollen in the midst of rut, muscles rippling beneath a sleek coat of winter fur, polished antlers gleaming.
During these stressful times when so many lives are being lost due to the pandemic, it is reassuring and soul-warming to witness death’s opposite: new life coming into the world. A few days ago, I looked out my window to see a herd of javelina, some of them less than 20 feet distant, heading for our bird-feeding area. At this time of year, this group of nearly 20 javelinas visits our place every day and also during the night – seeing them was no surprise, were it not for the newcomers. Several of the adult females had tiny young in tow, varying in age from one or two days to about a week.
Baby javelinas follow closely behind their mothers. Unlike many other native mammals, javelinas do not have a set time of year to give birth, but several females have appeared here recently with newborn young.
When javelina are very young, they often remain nearly hidden beneath their mother’s bellies. They are so tiny that it is easy to miss them as a herd wanders by. I have never pictured adult javelinas as cute or endearing, but a mere glance at one of their stubby-legged babies can quickly reshape one’s views. Those little buggers are, in a word or two, downright cute. They can become otherwise as adults, fouling bird watering dishes, forcing any attempt at gardening in this valley to include stout fencing, and eating much of the bird seed that we scatter for our avian friends. On one occasion, our dog was nearly killed when it charged directly at a full grown javelina. In a split second, the dog was howling in pain as it returned at top speed with a life-threatening gash. Javelina are powerful and deceptively quick. They are well armed with a set of formidable, self-sharpening tusks. The poor little dog simply did not know any better. I did not reach for a rifle after the event occurred. The javelina was simply defending itself; in my mind, it had as much right to be on our land as we do. “Our” land is a place shared with other life. Enough said.
A javelina explores the world with its mother only days after its birth. Female javelinas are protective of their young, as all good mothers are. It is wise to give them room when very young offspring are present.
A year ago, another visitor appeared on a cool winter morning, an animal in serious distress. A hooded skunk had been lured by curiosity to the edge of an empty pool on our property, where it slid down into the bottom, only to find itself suddenly trapped. The vertical walls of that small pool are 5 1/2 feet high. Skunks are not built to be high-jumpers or cliff scalers. Normally, I keep an escape ramp positioned in the pool; a long 2×6 board. I had removed it the day prior when I had cleaned some debris out of the pool, but for whatever reason, I had not replaced it afterward. As soon as I discovered the trapped skunk, I replaced the ramp, sliding it down into the pool gently so as not to put the animal into defense mode. It did not take long for the skunk to walk up the ramp, out of the pool’s clutches.
Empty pools are wildlife traps. A simple escape ramp can make all the difference. Such ramps are also recommended for livestock watering troughs, allowing birds and other small animals a way to get out. A small amount of kindness can go a long way. Here, the hooded skunk ascends its way to freedom.
Once free, the skunk began to amble about, seemingly unruffled by its prior confinement. It was searching for food, and hardly paid me or my wife any mind as it stood less than ten feet from us. I have encountered other hooded skunks in the valley before…every meeting with these creatures had left me feeling that they were utterly inoffensive and little concerned with my presence. Some neighbors reach for a shotgun when skunks come near their dwellings. Doing so shows a distinct lack of respect for other life and a lack of knowledge when it comes to coexisting with certain wildlife. Much like rattlesnakes, skunks are shy and inoffensive, unless they feel threatened. I know that if I were as small as a snake or a skunk, I would want some potent defensive measures. The rules are simple: maintain distance between oneself and such creatures and leave them alone. Maintaining distance assures one’s self protection. Leaving the animals alone and undisturbed shows respect.
Hooded skunks grow tremendously long tail hairs, a beautiful hallmark of their species.
Skunks bring special distinction to this part of the nation, for their kind are represented by four species here: striped, hooded, hognose, and spotted. Five species of skunks inhabit the United States. Only in a small part of southern Texas, southern New Mexico, and southern Arizonado the ranges of four of the five species overlap.
The skunk was in no hurry to run away after it was free of the pool. It wandered slowly, searching for food, as we stood watching less than ten feet away. This creature was mellow, inoffensive and beautiful; never once did we think we might get sprayed.
