Two Mornings in the Utah County Desert

Utah has three major biomes--deserts, forests, and wetlands. Being able to enjoy the plants, wildlife, and scenery of each biome in a single day makes Utah a unique and wonderful place to live. For the past two Saturday mornings I have been able to leave home before sunlight to go explore some of the desert wildlife of Utah County with my friend Eric Peterson. Eric and I share a love for exploring the outdoors and photography so it's practically guaranteed we'll discover something fascinating to observe, enjoy, photograph, and share with others.

This past Saturday... 

We were on our way to search for some Short-eared Owls in what we locally call the West Desert.  It was about 6 AM when we noticed the rising sun was working its magic on the clouds behind us so we stopped to take a look.

We made our way to some desert farmland and quickly found our first Short-eared Owl of the day. He was perched on a stick at the edge of the road. He flew across the field and away from us before we were able to get a close look. We continued along the road where we got much closer looks at a female Short-eared Owl. She was standing on the edge of the road near some tumbleweed.

We saw a handful of these owls in the fields bordering the road. Some flew across the road a head of us and circled above us.

I'm still trying to figure out how to get my new 80-400mm lens to work as well as my previous 300mm prime lens when it comes to birds in flight so I didn't get the quality of image I desired for the flight shots. These two will suffice for now.

During one of our stops for photographs I decided to capture an image of the habitat through which we were passing. The first one looks north and the second one south. It gives a feel for where the Short-eared Owls were living and hunting. They simply need a place to roost/rest/nest, generally on the ground, and open spaces for hunting. These owls are much more active than other owls during daylight hours, but dusk and dawn are the ideal times to see them in the right locations.

There were Western Meadowlarks, loads of Horned Larks, Northern Harriers, and a family of Loggerhead Shrikes breeding and thriving in this habitat. Some Pronghorns were successfully raising young ones in the area as well. My reading has taught me that Pronghorns are not true Antelope. In fact there are no antelopes native to North America.  However, locals refer to them as antelopes. We actually have a state park called Antelope Island in northern Utah. I guess Antelope has a better ring to it than Pronghorn Island State Park.

We discovered a number of raptors in the area, especially where we came across some trees or farm equipment and structures. One Prairie Falcon flew by early in the morning, but it was the number of Swainson's Hawks that I enjoyed. I've always wanted to get close looks at light-morph juvenile Swainson's Hawks. We ran across a few of them. One in particular allowed me a close approach and put on a bit of a show as it stretched its tail and left wing. Among Swainson's Hawks, only the young light morphs show the white head. As adults they all have dark heads. This one will eventually develop a dark head and a dark bib over the chest area.

After spending a little time watching the Swainson's Hawk we decided to try to focus on the Short-eared Owls again. As we were driving along the road I noticed some wings fluttering above the grass line of a field off to our left. We were curious to know what it was so we got out of the truck and walked toward the area. We expected a bird to take flight as we approached, but it was as if the bird we had briefly glimpsed suddenly disappeared. All we saw was an open field.

We moved forward a little more and before we knew it we were looking down at a Northern Harrier Nest. It was completely unexpected and the first time either of us had happened upon a harrier nest site. There were at least four young birds present. All were sort of tucked inside grass and facing a central spot where the grass was pressed flat from roosting and feeding.

A Long-billed Curlew began calling from behind us. It flew directly over our heads as it continued to call.

Looking back toward the nest I noticed the remains of what appeared to be a Kangaroo Rat. The blood was fresh so it was a recent kill and mill for the fledglings. Mom and dad were nowhere to be seen when we stumbled upon the nest site.

We left the nest site after a few images and continued our search for owls and raptors. We were fortunate to locate a total of four owl species for the day. We saw Short-eared, Great Horned, Barn, and a few Long-eared Owls.

We moved to a different location with a few trees and observed some type of moth caterpillar that was suspended in the air by a single thread that hung from a tree. I think you can call this an inchworm, but it was about three inches long. It will likely turn into a large moth. The sun was bright and washing out the subtle colors of the worm with the first few images I tried. I turned down the exposure compensation and it seemed to do the trick. A few of the images turned out okay with that change.



You can barely see the silky thread in the image below. What a colorful little worm/caterpillar with what appears to be some sophisticated anatomical parts. My understanding is, however, that these worms can destroy the foliage of trees in a hurry if not kept in check.


Another highlight from this past weekend was a family of Long-eared Owls. The young ones were curious about us. The adults were a little more guarded.

Two Saturdays Ago...

Eric and I were exploring around the Soldier Pass Road area of the desert west of Utah Lake. One of our target birds was the Gray Vireo. They are very rare for northern Utah, but they are common in this small area of Utah County. It didn't take us long to hear and see several individuals singing from juniper trees.

Gray flycatchers were breeding in the area. We came across a male and female in one location after we parked and walked along a hillside.

We encountered a number of bird species expected for the desert that day. We knew that Common Nighthawks were breeding in the area. We saw many of them flying around us. Nighthawks nest on the ground so when we saw an adult bird acting like it couldn't fly and hopping along the ground ahead of us we knew we were near its nest site or young. We didn't see signs of either and simply continued our short wandering through the desert, careful not to step on or disturb anything.

Lizards are common in our desert, but I had never really paid them much attention while birding. I changed that when we came upon some adult Western (Great Basin) Whiptails. I enjoyed a short photo session with a couple of them as they moved between juniper trees. These lizards were about 10-12 inches long from nose to tip of tail.

The Utah County desert awaits you. Go and explore it. And be aware that what is amazing about nature can also hurt you. We do have rattlesnakes and some cacti and other plants will poke you so give proper respect and you'll have a great time.

Birds of Soldiers Pass and the Sound of Rice Crispies?

I thoroughly enjoyed spending a Friday afternoon and all day Saturday exploring parts of Zion National Park and the extreme southwestern desert of Utah a week ago so I decided I wasn't quite done with desert wanderings this past Friday night. I made the decision to get up early Saturday morning and head over to Soldiers Pass Road on the west side of Utah Lake in Utah County. My excellent birding friend and birding mentor Eric Huish had shared his experience of birding Soldiers Pass Road about two weeks before and it sounded like a fun place to explore, especially since he had reported Gray Vireos in the area, a bird I had never seen in northern Utah. The habitat is arid and hilly and begins with sagebrush at the low elevation and turns into pinyon-juniper at higher elevations. The possibility of seeing rarities and area specialty birds only 30 minutes from home was very appealing.

I arrived at the Soldiers Pass turnoff, a few miles south of Saratoga Springs on SR 68, around 6:30 am. The sun was just coming over the mountains to the east and I was in hilly territory so the sun was reaching some east-facing spots of the hills and valleys of Soldiers Pass while still being hidden from most of the pass. Bird activity was still a little slow at that time due to the mostly shady conditions. However, I did get to park and observe a somewhat nervous yet curious Jack Rabbit as I waited for more sunlight to grace the pass.

The first singing bird I heard then saw as I drove slowly up the pass was a Spotted Towhee. I could soon hear the chipping of Lark Sparrows coming from about ground level and from inside the junipers.  A Northern Mockingbird was soon heard then seen on a hillside. The west side of Utah Lake is a nice place to see the otherwise rare bird for northern Utah. Mockingbirds are much more common in southern Utah. Just as I reached a hairpin turn on the gravel road which rose into the sunlight I heard and spotted a couple of  singing male Black-throated Sparrows. This area of Utah County is also one of the few places in Northern Utah for reliably seeing these handsome sparrows. The soft morning light shone on the these birds as they sang from their respective sagebrush and juniper perches.

The hills were coming alive with singing birds with the sun shining on most areas of the pass--Northern Mockingbirds, Spotted Towhees, Lark Sparrows, House Finches, Brown-headed Cowbirds, and more.  I stopped my truck at one point to try to identify a song that was both familiar and unfamiliar at the same time. My brain was processing at a very slow speed, but it eventually came to me. It was the song of a Gray Vireo--the song I had listened to a few times on my phone's bird recordings earlier in the morning. I retrieved my phone, searched for Gray Vireo and then played their song. It was a perfect match. I pulled up the binoculars and located the bird singing from a hillside. I exited the truck, followed the song as I hiked up the hillside, and found a small open space between juniper branches to frame my first Gray Vireo image of the day.

After sneaking a few images of the bird from my juniper hiding place I decided to move closer to obtain the image below. The Gray Vireo is a rather plain looking bird, but it was fun to hear them sing and watch them move about their habitat.

Below are images of the very first Gray Vireo I ever saw. It came to investigate me as I was attempting to photograph birds from behind some brush  in southern Utah a couple of year ago. At the time I thought it was a Blue-gray Gnatcatcher. My friend Eric Huish pointed out that it was a Gray Vireo when he saw the images after returning from my trip.

The image below shows that the tip of the upper mandible actually crosses over and down slightly to the side of the lower mandible. I don't know if that is typical or not.

When my friend Eric first reported hearing a Gray Vireo on Soldiers Pass a couple of weeks ago he said it was hard to hear the birds singing because a Cicada emergence was taking place and there were ten or so Cicadas calling from every sagebrush and juniper (thousands) in the area. The emergence had passed before I arrived this past Saturday, but I did here Cicadas clicking their wings from nearly every juniper bush. When I stood still and listened to these Cicadas clicking their wings it sounded like someone had just poured milk over a very large bowl of Rice Crispy cereal. The whole area around me was making that familiar soft popping sound. While I've had my share of Rice Crispy treats over the years, I haven't eaten a bowl of Rice Crispy cereal for a very long time so the sound took me back a few years, almost to childhood.

This Lark Sparrow was perched near the Cicada I photographed above. The sparrow took flight just as I was getting focused on it in its perch. I wasn't quite ready for an action shot.

Shortly after leaving the Cicada and Lark Sparrow I saw a couple of Loggerhead Shrikes. I didn't get any photos of those birds, but here a couple of images of one seen previously on Antelope Island in Davis County, Utah. These predatory songbirds will prey upon insects and small rodents, as seen in the first image below. I watched the bird below drop from the thistle perch and take the small vole from the grass below. Shrikes will often impale their prey on  sharp thorns, barbed wire, or some other sharp object for later consumption.

Doesn't the look below seem to say, "Don't mess with me!"?

Back to Saturday's images from Soldiers Pass. Another birding friend of mine, Martha, coincidentally birded the same location Saturday, but she arrived about an hour behind me. I met her coming up the pass as I was heading down. Together we chased the call of a Common Nighthawk. We hiked up a hillside from which we also heard two Gray Vireos singing. One Common Nighthawk flew over our heads as we stood near the top of one of the hills. We enjoyed watching the bird do its flight display. It would circle higher and higher while giving its insect-like "beeerrz" call and then take a steep dive and give its soft "boom", more like a humming "oooovvv" sound at the bottom of its dive. The bird came close at one point, but flew between me and the sun as it did so. Looking into the sun kind of blinds a photographer so I missed that shot. I did manage the image below as the bird flew high overhead. I increased exposure compensation in the field knowing the bird was back lit. That helped, but I also had to crop the image quite a bit to show the detail that is seen below.

These birds are generally crepuscular, active mostly during dusk and dawn hours, as they hunt flying insects. They nest on the ground in gravel or on gravel rooftops. The flight display of this bird may have been to attract a mate or claim territory near an existing nest.

I want to share a better view of these summer visitors to Utah so here is a photo of the first Common Nighthawk I ever saw and then some taken while watching nighthawks feed on flying insects over an agricultural area near Lakeshore, Utah.

A pleasant surprise for both Martha and me was discovering two Juniper Titmice that were first heard then seen as they flew into some junipers and foraged for insects. They were probably a breeding pair considering time of year and location.

I saw my very first Juniper Titmouse a couple of years ago as I was beginning to hike into Yellow Fork Canyon in Salt Lake County. The image below is of that first titmouse. It was carrying food in its bill. That is a sign that it was taking food to a nest or recently fledged birds. Otherwise it would have wasted no time swallowing the bug.

Martha told me earlier that she was going to drive over the summit of Soldiers Pass Road and down into Cedar Valley to meet her husband George, who is a pilot, at the small airport in Cedar Valley. While we were visiting after observing another Gray Vireo together Martha's attention was drawn to the sound of an airplane coming toward our location. It was her husband George!


Somehow, despite the sound of roaring propellers during George's flyover, I heard the chatter of a pair of Bushtits coming from behind us. Martha and I both got a quick glimpse of the Bushtits before they disappeared into some cover. I managed one quick shot from a distance of one Bushtit as it very briefly popped up and perched on a juniper.

Here's a closer image of a Bushtit I captured in my in-laws' backyard in Cypress, California last summer. They are very busy and nomadic, rarely being seen in the same area except during nesting season when the eggs and babies require constant attention.

Martha and I eventually said goodbye and headed our separate ways.  Just as I reached the bottom of Soldier Pass and headed back to SR 68 I saw some Lark Sparrows. I noticed one sparrow was holding food in its bill and suspected it was taking the food to a nest. The bird flew down low into a sagebrush. As I approached the sagebrush I noticed there was a nest with three little babies. I hope you can see the dried-grass nest and get a sense of how well it was hidden inside a sagebrush.

I'll finish with an image of a Lark Sparrow I captured a few weeks ago on my way home from work. It represents the most frequently seen bird during my drive up and down Soldiers Pass this past weekend.
