A Day of Learning Flycatchers, Warblers, and More

by Bryce W. Robinson

Male Phainopepla- Phainopepla litens

This afternoon I took a trip to a place called Indian Canyon. I never expected to find such a place. In the midst of aridity and rock strewn mountainsides, a Palm covered drainage of flowing water empties into the Coachella Valley. With the amount of time I’ve spent in the water-less desert lately, this place was paradise. I had heard it was a great place to bird, and since the spring migration is in full swing, I expected to see some special species.

I was happy to find myself with new birds, particularly warblers and flycatchers. I must admit my knowledge in these two groups is lacking, and it has become an area of focus for my current study. Identifying Empidonax flycatchers are one of the biggest difficulties that the birder faces. There are a few species that are indistinguishable from one another. In many cases, the call alone is the only way to gain a positive identification. With this said, I found two different “empids” today that I feel fairly confident I was able to ID properly.

Pacific-slope Flycatcher- Empidonax dificilis

This Pacific-slope Flycatcher was a character. It sat on the ground, occasionally lifting to the air to swoop after and insect, returning to the ground to watch for more. It paid little mind to my intrigue. It was great to watch this bird and get to know its look and behavior.

I included the photo below to show a helpful ID tip when watching empids. The color of the lower mandible can help eliminate particular species. I was fortunate to capture this image as the bird looked my way, exposing a light colored lower mandible.

Another empid was flitting around the stream. Not assuming it was the same species, I took the time to watch and note features that might separate it from the previous bird. I never heard either empid call, so perhaps I should admit that I can not be absolutely certain in my ID. I will be bold, and say that I believe the second bird to be a Hammond’s Flycatcher.

Hammond's Flycatcher- Empidonax hammondii

Hammond’s do not breed, nor winter in the area, so this would be a migrant. That fact makes my time watching the bird ever more meaningful.

I’m beginning to find myself extremely fascinated with the warblers. They are a diverse group, and contain some of the most visually stimulating birds in North America. As a birder, they are a challenge. They hardly stay still, constantly jumping from limb to limb, deep in foliage. In old growth forests, multiple species coexist in close proximity as they occupy different zones of the canopy layer. This is a helpful fact in identifying birds as the birder sees fleeting glimpses of uncooperative warblers. In a palm dominated riparian zone, I had it easy. With relatively little understory and one canopy layer, I was able to spot multiple warblers and gain sufficient views to aid in my identifications.

The first warbler was a bird I had never seen, but knew nonetheless.

Wilson's Warbler- Wilsonia pusila

This Wilson’s Warbler was loads of fun. I watched it for a while as it travelled around, low to the ground, foraging for whatever it could find.

Another Warbler that was very present along the stream was an Audubon’s Yellow-rumped Warbler. These birds are very common, but always fun. In the desert the past week, I have been seeing a few migrating warblers. One particular difficulty I have faced is differentiating between what might be a MacGillivray’s Warbler and a Nashville’s Warbler. To the experienced birder, this might seem silly. I have no problem admitting that I am still learning some simple problems. Today, however, I finally saw a bird to solidify the knowledge to distinguish the two.

Eye-rings can be problematic. So can crown markings. After all, the Orange-crowned Warbler rarely shows the orange feathers on its crown that give it the name. The Nashville warbler is very similar to the MacGillivray’s, save some subtle differences. The broken eye-ring of the MacGillivray’s is certainly distinctive, but I daresay this is not the marking that should be focused on. The throat of the birds differ; the MacGillivray’s being gray, the Nashville’s being yellow. I was troubled at not being able to confidently ID the birds I saw this week. Today, I saw a few Nashville Warblers. I include a poor photo not for quality, but to show that in some  lucky instances, the bird looks just as the guides depict.

Nashville Warbler- Oreothlypis ruficapilla

The throat isn’t visible, but everything else looks great. Note the complete eye ring and rufous cap. I even saw this bird well enough at times to pick out the whitish vent. Today, I learned what makes the Nashville, the Nashville.

I saw a few Black-throated Gray Warblers today. They were all very friendly. I was so close to one bird that I had a hard time fitting him into the frame. I was unable to get any photos that I really like. Most are obscured by foliage, or butt shots. Too bad, but I did get a few for the reference library.

Black-throated Gray Warbler- Setophaga nigrescens

I haven’t seen many thrushes in my life, so it was great to see a Hermit Thrush wandering through the brush. I followed the bird into a thicket, where it sat still, allowing me to capture a few images.

Hermit Thrush- Catharus guttatus

The day was a great day of growth for me. I make attempts to take advantage of the opportunity to learn even a little each day. I love feeling like my knowledge is growing. I wouldn’t be happy if it were any other way.

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.

Roosting Western Screech Owl- Megascops kennicottii

With the help of friends, I was finally shown a needle in a haystack. I’ve searched long and hard for the cavity roosting Megascops kennicottii. I have repeatedly checked known roost sights with no success. After my experience the past summer with the Western Screech Owl, I became even more obsessed with finding the bird in daylight. Sometimes it’s about knowing the right people and getting lucky.

It is important to remain respectful when finding a treasure such as a roosting owl. The stress the bird undergoes if it is flushed can be detrimental, especially in the winter months. If you are ever so lucky to find a roosting owl, glimpse the bird and move along. Do not overstep your bounds. After all, it would be worthwhile to ensure that the bird is comfortable with the roost sight, feeling safe and sound to return time and time again. It is then that you will be sure to have plenty of opportunities to watch the daytime dozings of the darkness dwellers.

Falling Into a Red-tailed Fascination, With a Harlan’s Twist

by Bryce W. Robinson

Juvenile "Harlan's" Red-tailed Hawk- Buteo jamaicensis harlani

I rarely begin a post with a picture, however, I would like to pay tribute to one of the most remarkable creatures to occupy the sky. For reasons truly unexplainable, I find myself fascinated with the varieties of the Red-tailed Hawk, particularly and most intensely, the Harlan’s. The striking plumage and variable tail patterns certainly seem to be the most fascinating aspect of the Harlan’s. Perhaps it is the little known aspects of the birds great north breeding ecology, and the overlap with other Red-tailed strains creating intergrades and even more peculiar and strange forms of this relatively common species. I find the Red-tailed world intriguing on multiple levels, and I have made the goal of a lifetime study of the bird. In my search to specialize for my graduate work, I do at the moment believe I have found my candidate.

I spent the other day photographing birds with Jerry Liguori once again. Of course he lent me his equipment for more photography fun. I still can’t put a finger on why he would be willing to do so, other than his kindness. So I must admit, this entire post is all due to Jerry’s kindness, and I would not have been able to get any images near the quality of what is shown without his help.

Jerry has studied raptors for years. He also has a keen interest in the Red-tailed Hawk. He has written many articles on Red-tailed variants like the Harlan’s and the Krider’s, and has shared a few with me. I have gained much satisfaction in browsing through a number of Harlan’s tail shots that he sent me, illustrating the vast variety that exists among these birds. I actually blame Jerry for feeding my obsession with the bird. Now he has to put up with my endless intrigue as I pick his brain for answers regarding Harlan’s.

On this outing we went to an area of particular popularity due to the high density of wintering raptors. As any Utah birder likely knows, the area I speak of is the basin directly south of the point of the mountain. The birds detailed in this post were all photographed at this basin. Keep in mind that I stayed in place for a few hours, and the amount of birds featured in this post occupy the area around the basin, which is little more than a square mile. Wintering ecology is an amazing thing, as normally territorial birds put up with others, not even of the same species, and share the resources at hand.

This year, multiple reports of Harlan’s Hawks at the point have hit the hotlines. I had visited the area in November, and saw a Harlan’s, but the soaring raptor was much too high for any reasonable photography. On this day with Jerry, my luck changed. We had a Harlan’s fly in close to provide me the opportunity at my first close range photo shoot of my favorite flyer of late.

This young Harlan’s is a favorite of another Utah birder. Tim Avery constantly posts his images of the point of the mountain Harlan’s. He met up with us after a while and was right alongside me when the bird came in for the shot. According to Tim, the photos he took were the best Harlan’s he has to date. I must admit, I like his shots better than mine.

The young Harlan’s was actually not the most exciting bird of the day. As Jerry and I drove south on the freeway before reaching the basin, I told him of my lack in confidence for identifying a light-morph Harlan’s, and how much I would love to see one in the field. I feel that some of Jerry’s self proclaimed luck then rubbed off on me, or perhaps I was just lucky enough to be with him, but one of the first birds we saw as we came to the basin was in fact an adult light-morph Harlan’s. Regrettably our luck only went so far, and I never reached a close distance in order to photograph the bird. Jerry, with his great lens, actually caught the bird from behind as it landed on a post. The tail was perfectly spread, exposing a silver-ish base fading to a nice reddish tone. A few feathers even had some slight banding. A perfect Harlan’s tail, and a beautiful bird.

There were a total of three Harlan’s at the basin that day. I photographed two, both of which were juveniles. The second bird displays perfectly an aspect of my fascination. The white breast is peculiar, and sets it apart from the other young bird we saw later. I love the variation, and I can’t get enough of studying these birds.

It was delightful to watch the numerous birds interact with each other. Near the peak of the mountain five birds flew, toying with one another. As it appeared, the birds seemed to be enjoying the sun, with full crops and playful spirits. As I watched, I noticed that one of the birds was in fact a Rough-legged Hawk. The interaction did not appear aggressive, which made the sight much more peculiar. Seeing the Buteo’s fly together reminded me of a bird found last year in the mid-west. It appeared to be a hybrid between a Red-tailed Hawk and a Rough-legged. When breeding season comes, and birds have trouble finding a mate, it can happen that two birds of different species pair up in desperation to procreate. I have even heard of Ferruginous Red-tailed Hawk hybrids.

One of the reasons I am so intrigued by Buteo jamaicensis is the variable plumages that exist. The Western Red-tailed Hawks that were present provided a great look at the variety present in even the more common strain. From juvenile to typical adult, all were there. I would have liked close up photos of all of the birds that day, but birds are only so cooperative, or better said, I am only lucky to a point. Still, I came away with great shots of a number of birds.

Typical adult Western Red-tailed Hawk

Jerry mentioned an interesting point after seeing an adult western bird with a white throat. Apparently some years back it was common knowledge that western RT’s lacked a white throat, like the typical bird above. This fact was cited in many guide books for the hawks of America. I found this interesting because it illustrates a point that Jerry has really tried to engrain in me, or so it seems. Facts about birds depend upon research, some research more thorough than others. We as birders, or those enthralled enough to give a damn about the particulars, need to be comfortable with getting things wrong, making mistakes, information changing, and especially saying “I don’t know”, from time to time. I respect Jerry’s humility, and his concern for passing that on to me and others who share his passion.

The fact is that with a bird so diverse in plumage as the Red-tailed Hawk, there is going to be some overlap and interbreeding between regional “subspecies”. What results are birds that show characteristics of one strain, but overall resemble another. I found a bird a few weeks back that was a dark morph western Red-Tailed Hawk, yet it had a heavily banded tail that faded from a cream color at its base to a nice orange at the terminal end. At first glance I was excited at the possibility of a Harlan’s, however when I reviewed my photos, I found the bird to be a nice chocolate brown with rufous highlighting. After consulting Jerry, I learned of the importance of leaving some birds a mystery. The bird could have been an intergrade of some sort, or something else more mysterious and exciting. For now I have no conclusion, but I have come to terms with that and moved along. In the future, I may find another bird that shares the same traits, and may be armed with the knowledge and resources to discover where the bird is from and why it is so peculiar.

It was nice to see a variety of Red-tailed Hawks, but what made the day even better was when the Roughies were thrown into the mix. Because I conduct winter raptor surveys, I find myself with plenty of opportunities to photograph these arctic birds, but with Jerry’s help, I believe I came a way with my best photos to date of Buteo lagopus. They are at least in a close tie with those photographed last week using the same camera and lens.

Juvenile Rough-legged Hawk- Buteo lagopus

It seems that I only find Juvenile Rough-legged Hawks this year. What that fact is attributed to I can only wonder, but perhaps it is tied to wintering ecology, perhaps not. While we watched two Rough-legged Hawks soar together, Jerry and I heard the high pitch call of the birds. This was the first time the call of Buteo lagopus settled upon my ears. I did not take it for granted, and I will not forget the sound.

Juvenile Rough-legged Hawk

Although the point of the mountain is frequented with large, loud, and stinking trucks, it is a special place to gain a glimpse into the wild world. It stands as an inevitability that the area will soon be crowded with humanity, and there will no longer be a place for these wintering birds. They will undoubtedly find fortress someplace else, and we birders will follow. Still, how wonderful it would be to see these birds respected, and their winter home set aside from the expanding suffocation of the human world. I see no reality in the idea, as Utah County continues to grow faster than an adolescent boy, but may the seed be planted and pondered on. If you love raptors, make a point to visit this area. If you are respectful of the birds, and the truck drivers that pass, you will certainly have the best day of raptor watching you could ever ask for.
