A few weekends back I had the good fortune of finding myself on an Audubon ranch in southern California. Starr Ranch is an incredible coastal forest tucked behind a large gated community in Orange County. I came to the ranch to band owls.

The night was incredible. We had a few Big Brown Bats find their way into the nets, providing me the experience of seeing these winged mammals up close. I have never seen teeth so delicate yet fierce. We did have luck with capturing owls. Our first owl of the night was a beautiful female Barn Owl. I was able to take her from the net and band her. Having this ghostly creature in hand, staring into its dark marble eyes, is an experience I will never forget.

We also had four Western Screech Owls caught in the nets. I love the small owls, and was looking forward to the chance of banding one of these birds. The small birds are so endearing. Cute fits them perfectly, they are so full of fight and life. Returning the bird to the night was spectacular. I walked to the woods and perched the bird on my fingers. It sat for a while, not certain of its ability to flee. After a minute or two, the bird took to the night air and disappeared into the dark.

Today I spent my afternoon illustrating a headshot of the Western Screech Owl. I thought it appropriate to revisit this subject, given my recent intimate interaction with the bird. Every time I finish the owl, I feel a bit dissatisfied with the outcome. For whatever reason, I can never get the owl quite right. I would have probably loved this illustration if I would have left the ear tufts tucked back. I feel I drew them a bit too long. Still the exercise was rewarding, and I’m sure I will come out with a screech owl I am happy about if I only keep trying.

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.

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.

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.

Western Grebe vs. Clark’s Grebe- An Easy Tip for Distinguishing the Two

by Bryce W. Robinson

The past fall, I travelled the roads of the Bear River Migratory Bird Refuge in search of wayward migrants and peculiar passersby. I found the waters full of many birds, but the most prevalent was the black and white Grebe. Thousands upon thousands of these birds littered the waters, feeding and resting, preparing for the next leg south to their wintering waters. I have seen many grebes in my day, and I admit that something about the birds intrigues me more than usual. Perhaps it is the way they carry their young upon their back, and dive into the water at the first sign of danger, only to resurface with the chick still riding steady. I have followed grebe in my kayak many times, and observed in depth their defense technique as they dive and resurface farther from me.

The grebe is designed to swim and dive for food. Their hind legs are positioned farther back on their body than normal, making them awkward and clumsy on land. As lame as they appear on land, they make up for in the water. Their mating display is famous. Pairing up, two grebes run synchronously along the water until diving. Such a bonding display leaves the birder in awe.

While I watched the grebe populations this fall, I realized the identification difficulty that is present between two species of north american grebe. I would like to illustrate a technique I use for study, in hope of communicating not only an easy answer to an overwhelming question for new birders, but also a way to quickly solve any difficult learning problem in bird ID.

The Western Grebe and the Clark’s Grebe look identical at first glance. As the two distinct species occupy the same range and habitat, it becomes a challenge for the beginning birder to differentiate the two. I have illustrated the difference, which not only solidifies the fact in my own mind, but may better communicate the ideas that I write for the reader.

The Western Grebe has a black hood that is pulled over the red eye, while the Clark’s has a hood that sits like a cap. With white above the eye on the Clark’s, and black surrounding the eye on the Western, the two become easily distinguishable, even at quick glance.

Truly, the Clark’s can show some darkness around the top of the eye, but this fact illustrates an easy way to distinguish the two. One factor I failed to include was bill color. The Clark’s Grebe will have a more yellow bill than the Western. More uncommon than the Western, the Clark’s will join into flocks creating a large group of both species much like I observed in the marshlands last fall.

Common birds are too often overlooked. I encourage you to stop at the next flock of grebe and watch. Watch the silly habits of the birds, and see if you can tell the difference between the two species. Getting to know these two birds will undoubtedly bring you as much pleasure as it has brought me.
