Owls In the Desert Night

by Bryce W. Robinson

Western Screech Owl- Megascops kennicottii

This evening I joined some friends on an owling adventure into the evening heat which still hovered near 100 degrees farenheit. We were in search of the world’s smallest owl, the Elf Owl. The desert of southern California is not the normal range of this tiny creature, but for whatever reason, there has been a bird living in one canyon for some time.

We watched some palm snags with nice cavities as the sun light began to fade. At one point, a small head poked from a cavity. We thought we had our owl, but soon after an American Kestrel flew from the hole. We were disappointed, even though a nesting kestrel is quite the prize.

The sun fell, and darkness ensued. No owl. After a while we realized we would no longer be able to see the owl, even if it was around. We listened for any calls, but none came. Before we left we decided to check for other owls. We knew there were probably screech owls in the area. They had been heard before. We whistled a few calls and listened. Sure enough two birds responded. Interestingly, the birds were perched ten feet in front of us on some limbs. We had some great looks at them.

The two birds called, and each bird had an obvious difference in pitch. One bird was noticeably lower. I know that in many species of owls the vocalizations differ, with the male being a lower pitch. I’ve heard this many times in the Great Horned Owl as they hoot back and forth at the inception of nightfall. I’m not certain if there is a difference between male and female voices in the screech owl, but it certainly seems so. I plan to do some reading to find out.

Although we were unsuccessful in finding the Elf Owl, I was very happy with the night. An owling adventure is surely successful when any owl is found.

Birding Blythe, CA

by Bryce W. Robinson

Blythe, California is not a destination for most. The small town is a bit run down and simple, not necessarily what anyone would have in mind when thinking of southern California. Still I have found beauty here. Surrounding the small town are green fields of alfalfa and other agricultural developments. I find myself here for work, living from a motel, and birding the surrounding farmlands for leisure. Possibly my favorite part of being in Blythe is the proximity of one of the west’s greatest river, and undoubtedly my favorite, the Colorado. As you can imagine, the unnatural clear waters of the southern Colorado draw in a number of birdlife and create a wonderful scene for  birding adventures. Truly the river is the only reason numerous green fields scatter the desert countryside.

While out birding the agriculture fields Yesterday, a co-worker spotted a treasure just outside of town. Along the roadside, atop an irrigation sluice gate, sat a docile Burrowing Owl. We watched the bird as it dozed, occasionally glancing around but otherwise disinterested in going-ons. I couldn’t stop myself from snapping shots, but due to the size of the bird, and our distance, I was dissatisfied with any of the photos I came away with.

Today I took hope in the chance that the bird would be in the same place, and sure enough the bird sat vigil to the same scene. This time around I resolved to decrease the distance between the owl and myself. I succeeded and the bird payed no mind. Still, the photos I have leave me wanting, but with the excitement of the experience and my desire to share, I have decided to include the bird in my report.

Burrowing Owl- Athene cuniculeria

Burrowing Owls are one of the most charismatic members of the avian community. Their mannerisms can be extremely amusing at times. I will surely be visiting this bird often, and documenting our time together.

I haven’t spent much time birding outside of Utah, and as a result, I am seeing many new birds. Among these include a few flycatchers that are not present or numerous back home. Apparently someone spotted a Vermillion Flycatcher the other day by the river, so I will certainly be after that till I see it. I did have a little related luck today in finding a tyrant, the Black Phoebe. This bird is wonderful, and I believe it has entered my mind as a candidate for future illustrations. Soon, very soon. Until then, a photo will suffice.

Black Phoebe- Sayornis nigricans

Another Tyrant that I have not known well till now is the Say’s Phoebe. Here in the Mojave, the Say’s are numerous, but I do not complain. They are a treat to and a wonder to watch, drawing me into their world.

Say's Phoebe- Sayornis saya

Of course with flooded green fields come insects and food for numbers of birds. I was delighted and surprised when I found a flock of white birds in an alfalfa field. It has been years since I have seen the Cattle Egret. These small birds belong to a group that are special to me. Watching them brings me back to my younger years of birding, and reminds me what I am searching for when watching birds. As with most of the birds of the day, the egrets I found were tolerant and cooperative.

Cattle Egret- Bubulcus ibis

The shores of the river housed a great deal of birds. As always, waterfowl were scattered across the mellow current. The American Coot was numerous, but intermixed and occasionally, I found some interesting birds. The other waterfowl that floated along included the Ring-necked Duck, the Canvasback, the Mallard, and a few Common Goldeneye. While watching a small group of Goldeneye, I noticed a Barrow’s Goldeneye grouped with a Common. This is probably a normal occurrence, but it was new to me.

Female Common, Male Barrow's, and Male Common Goldeneye, respectively.

Our raptor total of the day was incredible. Within a five minute interval, we saw three species of Falconidae, ending with a circling Prairie Falcon. I was unable to get any acceptable photos of any of the birds. This will be a task for the time to come, but for now I would like to share a photo that is a first of mine. I have never photographed the Turkey Vulture in flight, yet I felt the need and took the time and I believe it paid off. It is indeed a task of mine to maintain a comprehensive photo library, and the Turkey Vulture is certainly and integral part of a complete list.

Turkey Vulture- Cathartes aura

While working, I have been monitoring a few nesting Red-tailed Hawks. Of course the bird is a favorite and even a fascination of mine. I must admit I was surprised to see the difference in the birds this far south from those present back home.. The birds I have seen so far only add to my desire to learn more about plumage variations in this incredible buteo. I have been chasing some birds in hopes of photographing the them in good posture from below, illustrating in whole their plumage, to cross reference with the photos I have from the birds back in Utah. So far I have been unlucky, but I will continue to try.

I wouldn’t recommend Blythe as a destination for most, but for birders, I would suggest spending the time, as you pass through on I-10, to exit and visit the river and the adjacent farmlands. If you have never birded the desert of southern California then I certainly suggest. I will continue to bird the area, and report what I find. Soon, I hope to convey the unrecognized ecological treasures that the town of Blythe presents.

Winter Raptor Surveys- The Second Stint

by Bryce W. Robinson

Winter leaves a landscape sometimes snow covered with skeleton trees and frozen waters. Many find winter dampening, depressing, and void of beauty. I however, feel otherwise. My second stint in search of wintering raptors was full of breathtaking scenery and striking beauty. The desert aesthetic is an acquired taste for some. I myself have always been drawn to the subtle beauty of the sage steppe. After this past week, I have a renewed value for winter in the high desert. Sunset casts a warm glow across the cerulean lands, creating a calm comfort for all that feel. The juxtaposition of the warm glow of the setting sun against the harshness of the winter world and the impeding night is a wonder of the natural world. Balance is ever present, and even the wild creatures know enough to take advantage of the simple pleasures in life.

I came upon the Short-eared Owl atop the wheel line, watching the sun fall into the western skyline, seemingly dazed and content with the time at hand. In retrospect, this scene speaks to me in many ways. Perhaps the wild ones feel the importance of taking advantage of the simple pleasures of life, and slowing down to enjoy when times are good. No doubt that due to the way the owl reacted to my presence, it had recently finished a meal and needed nothing but to enjoy the warmth of the sun before the frigid frosts of night.

Colors are not vibrant or particularly potent in the high desert, but they are of course present and play a dramatic role in creating the world that I love. Taking in the expansive valleys surrounded by large goliath stone mountains creates a sense of mortality, deep time, and insignificance of individual life. These feelings coupled with the spectacular images provided by the sunlight and its play on snow filled clouds moving high above the valleys provides a sensational experience. I often found myself in deep thought and feeling as I reflected upon the wonders of the Great Basin.

The beautiful but simple colors of the desert provide the perfect backdrop for the many creatures that accent the scene. Many gregarious species travel the sage and rabbitbrush in search of food. The Juniper Titmouse is perhaps a favorite, and the sage landscape’s Bushtit, but of the many sparrows and larks, bluebirds, even buntings, the lone Loggerhead shrike is a favorite. The way the bird travels and hunts is delighting. Perched atop a shrub, the shrike steadies, surveying for prey. The bird’s flight is full of swoops, and charms the eye with the contrasting black, grey, and flashing white. In winter, the Loggerhead is joined by a relative, the Northern Shrike. I was lucky to find this relative and recognize what separated it from the Loggerhead. I was, however, unlucky in capturing an acceptable photograph of the bird to contrast it against the Loggerhead.

Raptors were everywhere to be seen. From the farmlands into the desert, the birds occupied every niche. Each time I came upon a bird, I did my best with identification, to glean information the best possible particular, and photograph with every opportunity. A bird that was more present than the previous November stint was the Rough-legged Hawk of the great north. With every Rough-legged I practiced my identification, strengthening my skills and enhancing my experience with the birds.

Identifying Hawks In Flight

As the Rough-legged Hawk was more present this month, I took the opportunity to hone my identification skills down to the particulars. In flight sexing, if possible, is very difficult. With some raptors, even ageing becomes nearly impossible. With the help of the camera, I was able to make take my impressions and assumptions, review the photos, correct my mistakes, and cross reference my field guides for the most precise analysis I could muster. This approach is what I call in depth field study.

The above photos are examples of what I would so often see as I watched a bird through my binoculars. I was able to tell almost instantly the species, but narrowing my ID any further became a challenge. The bird above flew through the area quickly so an in flight ID of sex and age was not possible. After reviewing the photos I found that due to the mottled under-wing lining, obvious dark bib, and dark trailing edge to the wing, this bird is most likely an adult male. There are pitfalls to some of these criteria, but I feel fairly confident in this ID.

While photographing a Horned Lark in a high desert valley on my last survey day, I noticed a large shape growing larger in the sky. Looking up, I saw the familiar flight of another Rough-legged wandering north, perhaps in search of food. The bird flew directly overhead, giving me a great opportunity to photograph and observe at close range. The excitement kept me from making any ID on sex or age, but again I went back to the photo to see what I could tell about the hawk. The most notable feature is the nearly black belly band of the bird. This coupled with the pale wing edge and tail band indicates that the bird is a juvenile. Also, there is a faint hint of paleness to the primaries, which supports the juvenile conclusion. Still, the mottled under-wing coverts and heavily marked breast make me wonder if this could be a male. So far in my study, nothing has told that it is possible to sex a juvenile. Perhaps this particular could be basis for future research.

The Ferruginous Hawk seemed to be more present this month as well. I saw many more birds in the farmlands and desert alike. The strikingly rich colors and contrast of the Ferruginous Hawk give the bird an heir of royalty. Its fierce gaze exemplifies this royalty as well. No wonder the bird was given the epithet regalis, for its regality is unquestionable.

While surveying an area only miles from the Milford wind farm, I saw a large hawk flying across the horizon. After a quick glance through my field glasses, I knew the bird to be a Ferruginous Hawk. With a silver head and nape, rusty red coverts, pale primaries, and prime white tail, the large Buteo could be nothing else. I have since researched how to tell the difference between an adult and immature Ferruginous, and I believe the bird below is a typical adult light morph bird.

Given the rufous upper-wing and underwing coverts, rufous leggings, and the white tail lacking a terminal band, I feel fairly confident in my analysis. As with all buteos, when the varying color morphs are introduced, it can complicate things. The Ferruginous hawks I saw were all light morphs, save one. Atop a power pole only half a kilometer from the town of Minersville, I found a large dark bird watching a field for prey. I was unable to get a decent photo, but the picture below will have to do. I cannot help but share the bird.

Given the lack of a terminal tail band, I believe this bird to be an adult. There is a dark trailing edge to the remiges, but due to my mediocre camera skills, I chopped the wing in any other flight photos I took. I plan to go back to the area on my third stint to find this bird again and make another attempt to photograph it. One particularly neat aspect to this bird, and you can see clearly in this photo, is that the belly is a bit paler than the rest of the birds body. Dark morph buteos, especially in lagopus, seem to retain their plumage patterns. This makes sense as the dark plumage results from an increase in melanin in the feathers. In the case of this Ferruginous, the increase seems to be in phaeomelanin, responsible for rufous tones, and the areas where the rufous already exist seem darker than the areas that are regularly pale.

I could not believe the number of birds that occupied the areas that I travelled. Without question, the most incredible experience of the second survey stint was seeing the Short-eared Owl atop the wheel line, glowing golden from the falling sun. Content for the time being, the bird watched the warm rays as they caught fire against the frozen valley. As I watched the dazed and docile bird, I realized that for the moment, the Short-eared Owl and I shared a feeling some call heaven, some call pleasure, some call perfect. It is a feeling I live for, found so often at dusk. It is the feeling of life, and the Owl and I let the feeling pour upon us like warm water. As cars rushed by, I wondered why others would not stop to watch the sun fall. As mortal creatures, as any life is, it seems foolish to ignore such instances. I want to think that somewhere in the bird that watched the sun, there was a feeling of mortality and gratitude for the sun. Probably not so, but the bird served as a messenger to me the sentient, and drew my attention to the sun, the giver, the life provider for all.
