Few places in the United States can rival the watershed of Arizona’s San Pedro River as one of the nation’s premier birding hotspots. A phenomenal richness of birds has been documented here – well over 450 species. Join me as I celebrate this gift of life with a sampling of our beautiful, diverse, and fascinating avian fauna…

Rare Autumn Color Transforms the San Pedro’s Forest
For the past three years in a row, I had made a date with the San Pedro River: I would spend my birthday walking the river under the gilded magnificence of tall willows and stately cottonwoods alight with prime autumn color. For the past three years, the autumn colors have failed to shine. “Autumn,” if you can call it that, comes late to this river’s riparian forest. Fall colors do not peak here until the second week of December. The timing does not vary due to temperature or climate, it functions via the most universal and reliable of nature’s temperate region chronometers: the photoperiod. In most years, the trees along the river either suffer a hard freeze before the second week of December, or they get stripped off by strong winds, or both. Freezes can rob the forest of its fall color overnight by turning all of the leaves a withered brown.
When conditions are just right, chlorophyll fades from the leaves to reveal anthocyanic compounds that transform the forest canopy into a fluttering galaxy of bright yellow leaves. This year brought a reprieve from late November winds and early December freezes – this was one of those special years…so I set out for a walk on my birthday, a serene journey into the river forest. The following images help to tell the story of a rare day on the river.
The first place I walked to that morning was a hilltop where I saw the lone cottonwoods pictured above, lifting plumes of sunlit gold skyward. As I watched, a great egret came sailing out from behind the trees! Imagine an elegant pair of outstretched wings spanning over four feet, the bird flawless, brilliant snow-white, set against a clear blue sky. My wonderful new binoculars brought this seldom seen creature in close and sharp – what a gift it was to witness the egret! My jaw went slack when a second egret appeared to join the first. The pair then departed northward, winging over the tops of the trees as they followed the river that sheltered and fed them. I envied their freedoms.
I left the hilltop, then returned to the riparian forest, where I walked down to a favorite sitting spot by a bend in the stream just below a vertical cutbank. There, a set of cougar tracks was pressed into the moist sand, made the night prior by an adult male. I sat under a willow to look, to watch, and to take in the morning’s biophony. The forest was quiet, the still air punctuated by a slight rustling of leaves above, the quiet murmur of the river water, and the voices of a few birds. As sunlight warmed the cool air, small clouds of midges began to rise within discreet, sunlit areas above the water. There, the air temperature was most favorable for their airborne gatherings. As the midges danced in the light, a gray flycatcher began sallying back and forth into the insect clouds, garnering breakfast with typically adroit flycatcher movements. Then another bird joined in the feast, flying into the swirling insects to garb morsel after morsel with some amazing acrobatics. It turned out to be a ruby-crowned kinglet! I had no that clue kinglets could – or would – engage in such feeding behavior.
Next, I walked down the river until I got near the northern terminus of my trail. The going was easy, the stream shallow in most reaches. I was glad to find no recent signs of trespass cattle anywhere, nor any signs of feral pigs. There was little in the way of animal tracks, as a heavy mantle of recently shed leaves covered most of the ground thoroughly.
As I neared the end of my walk, I veered into the forest to avoid some deep water. (For much of the way, I’d been wading.) The wind suddenly arrived, causing a blizzard of shimmering golden leaves to return to the ground that had bore them, an entrancing display of fluttering motion and light as one of nature’s grand cyclic acts of life unfolded all around me.
An Early Monsoon Photo Gallery
This year’s monsoon got off to an early start in mid-June, but thus far, we have received just 2.98 inches of rainfall. Many storms have passed by, missing us by only a few miles. Hope for more rain is justified, however, because the summer monsoon season still has a couple of months to go. Summer rain always brings a wonderful blooming of life to this arid landscape, most of which cannot be witnessed at any other times of year. Here is a brief gallery of some of those recent gifts…

Summer has come to the river and its valleys, bringing a cavalcade of change to the animal world. Today, my thermometer registered 113° F. I don’t leave southern Arizona during the summer like so many people do every year. This is my favorite season here, because so much happens in the natural world during the fierce heat of summer…
A Rare Bird Surprise, a Huge Insect, and the San Pedro River in October
It has been quite a while since I crafted a new post for this blog. During the past month, my life had been turned upside down with growing trepidation over the presidential election. I was not in a frame of mind conducive to writing. Now that the election is over, I feel a huge sense of relief and renewed hope. This was an election not only for the people, but one that will benefit wildlife and wild places as well.
I walked a perennial reach of the San Pedro River recently. There was a new beaver dam, just a tiny one that was still under construction. Turkey, javelina, bobcat, deer, coyote, opossum, raccoon, and skunk tracks were visible in the mud along the stream’s edges. I was intrigued to find a set of feline tracks that suggested ocelot or jaguarundi, for they were certainly not made by a bobcat and were just as surely not left by a cougar, even a very young one.
October has finally brought some relief from the heat that so characterized this summer…109 consecutive, record-setting days of temperatures cresting at 100°F. or higher. The nights have cooled off and crisp air now graces our mornings. Our local woodlands have quieted considerably with the departure of many migratory birds, but there have been some amazing avian happenings here this month. A very rare event happened not long after the sun had set a few weeks ago. My wife, Kathleen, and I stepped outside to listen to the nocturnal sounds coming from the mesquite forest that surrounds our home.
We heard it almost at once, a mysterious, alien-sounding voice emanating from midway up in the trees, only a few dozen yards distant. It was certainly an owl, but not a species that we had ever heard here before. On many a night, we have listened to the calls of great horned, western screech, barn, and elf owls in this woodland, but this was something new, something distinctly different. It suggested a screech owl, but both of us readily agreed that it was not “right.”
I had a growing hunch, so we went back indoors where we consulted a very useful website (xeno-canto.org), one that offers a multitude of audio files for most bird species across the globe. The first species that we chose to listen to was a bird whose range barely extends into the United States, a bird that inhabits oak and conifer habitats high on mountain slopes in extreme southeastern Arizona…
As soon as we heard the recordings, we realized we had a whiskered screech owl hidden in the darkness of the tall mesquites only yards from our home! This was an owl that should not be here, for we live far from the high mountain slopes in the floor of a low-elevation valley. I believe that a major wildfire event from this past summer may provide the answer to this enigma. Less than 20 miles distant, the Bighorn Fire torched nearly all of the mid-to high elevation habitats off the face of an entire mountain range, the Santa Catalinas. Countless birds were driven off of those mountains, subsequently appearing in nearby places where they would ordinarily not be expected. For example, my friend Woody Hume, a very capable naturalist, told me that he had numbers of western bluebirds appearing at his place of residence not long after the fire. That is a species one does not expect to see during summer in the valley floor. Other such unusual species have been reported here this year. I would not be surprised if the owl that galvanized our attention had been living high in the Catalinas and wound up here, temporarily, as it looked for a new place to live.
October and November brings new happenings in the insect world of southeastern Arizona. It is common to find adult preying mantises at this time of year. It is impressive to see one of these three-inch, bright green insects in flight. The individual pictured is an introduced species that has become widespread and firmly established in southern Arizona and other parts of our country.
