A Red-tailed Hawk And Red Lichen

Mia and I have been visiting the Centennial Valley for about five years now (usually 3-4 times every summer) and at least once each trip, as we passed this lichen-covered rock next to the road, I would mention to her how much I would like to photograph a raptor on one of these red rocks. There’s just something about my fondness for each, the lichen covered rocks and birds of prey, that has made that kind of photograph a personal goal. But it never happened for some reason. The birds of prey just don’t seem to perch on them, preferring instead the fence posts, utility poles and trees that are usually a little too far away from the road. It’s been an unfulfilled goal for a long time.

But all that changed last week.

Red-tailed Hawk – A Twisting Take-off After Prey

The sturdy, broad-winged buteos tend to be large raptors with correspondingly slower movements than most smaller birds. Most of the time when I’m watching them they’re hunting from an elevated perch or soaring overhead and in neither situation do they typically demonstrate much quickness or agility.

But they can put on quite the show when they need to.

Juvenile Red-tailed Hawk Honing Its Hunting Skills

For the past few weeks I’ve been working a pair of juvenile Red-tailed Hawks with varying degrees of success.  Mostly they’re just toying with me – staying just out of range or on the wrong side of the road in poor light.  But on two mornings the lighter colored of the two birds put on quite a show.  It chose to do its “sit and wait” hunting from a series of dark rocks close to the road and didn’t seem to care that I was there.  And close.    1/2000. f/7.1, ISO 500, 500 f/4, 1.4 tc, not baited The rocks are on the side of a small mountain with vole-laden prairie grass between me and the hawk so the bird would perch on them and then take off for prey it spotted – often in my general direction.  The prey is presumable nearly always voles though these young birds are usually unsuccessful.  It did catch and eat a small snake once but the action was buried in the grasses.  I’ve yet to see it actually catch a vole and that makes me feel sympathy for the hawk but on the other hand all these attempts at prey have given me some nice photo ops.       1/2000. f/7.1, ISO 500, 500 f/4, 1.4 tc, not baited Usually the setting had grass and/or rocks in the background and often it was close enough to the hawk to make focus-lock difficult but here the background was a little further away.  On both days by the time the bird cooperated the sun was high enough that the…

Stansbury Mountain Red-tailed Hawk

I like to photograph raptors (or most any bird, really) in this kind of light when I think I can get away with it.  When I first started photographing birds I always  made an effort to get the light source directly behind me and now I shudder to think of the interesting light I sometimes missed, especially since what I ended up with was often something rather mundane. I recently posted a somewhat similar image of a red-tail but the poses and settings in the two photos are quite different from each other.   1/2000, f/6.3, ISO 640, 500 f/4, 1.4 tc I found this hawk perched in dappled, directional light a few months ago.  It was near the bottom of a canyon in the Stansbury Mountains of Utah so I was looking slightly down on the bird –  a perspective I appreciate if the angle isn’t too steep.  I like the haughty pose – which was actually a reaction to another red-tail flying toward this bird.  Ron

Rough-legged Hawk At Take-Off

It’s been a good winter in northern Utah for Rough-legged Hawks.  I’ve seen many more this year than I have in years past and they were particularly abundant on Antelope Island and on the causeway.  On several occasions out there we counted 20 birds or more.  Their numbers have now thinned out considerably but there’s still a few of them around.     1/2000, f/6.3, ISO 500, 500 f/4, 1.4 tc  I found this one a few weeks ago perched in the grasses in front of a darker colored field of dried sunflowers.  The hawk was too obscured by the grasses for quality photos so as usual I set up for take-off.      1/1600, f/6.3, ISO 500, 500 f/4, 1.4 tc As the hawk gained elevation the darker sunflowers dominated the background but you can still see the out of focus grasses at the bottom of the frame.  I really like the backgrounds/settings the island often provides, though all that texture and contrast behind the subject can sure make it a challenge to get focus lock on the bird – particularly in flight. I’ll miss these handsome buteos this summer but hope they have a successful breeding season on the arctic tundra and return in good numbers again next winter. Ron

Golden Eagle – Some Progress On A Nemesis

Anyone who follows this blog knows that I have a penchant for raptors and over the last 6 years of photographing them I can count on one hand the number of good opportunities I’ve had with Golden Eagles.  I had another chance at one yesterday on Antelope Island.  I almost didn’t spot this bird because it was hunkered down so far in the sagebrush (here it is standing more erect in anticipation of flight).     1/1600, f/7.1, ISO 500, 500 f/4, 1.4 tc I knew that my only chance for a few decent images would be at take-off or just after but the angle of light was a problem – the bird was facing almost directly into the sun.  If it veered to its right I’d get butt shots and probably lose the head behind the wings.  If it turned to its left the face would be in shadow and I’d get no catch light.  What can you do but wait, be ready for lift-off and hope for the best from a less than ideal situation?        1/1250, f/7.1, ISO 500, 500 f/4, 1.4 tc  Thankfully the eagle launched straight ahead which gave me the best light I could hope for under the circumstances.       1/1250, f/7.1, ISO 500, 500 f/4, 1.4 tc   For the first wing-beat I got light on the head and a catch light in two images – then the bird turned slightly toward me and that light was lost.  I got several more sharp shots with dynamic flight poses but the face was completely shaded.  Curses !!! I…

Red-tailed Hawk with Long-billed Hawk Syndrome

This morning I found this Red-tailed Hawk on a telephone pole near Grantsville, Utah.  As soon as I looked at it through my lens I knew that something was wrong with the birds beak.    A bit of research almost immediately turned up the probable culprit – Long-billed Hawk Syndrome.  Birds with this condition have atypical uncontrolled growth of either or both upper and lower bills.  Birds affected often have secondary infections in their bills.  Since their bills are used for activities such as eating, preening, killing prey and feeding offspring the syndrome is extremely serious.  Most birds with this condition die of starvation.       The syndrome gets its name because most affected birds have been Red-tailed Hawks, though other species of raptors get the condition also, including Peregrine Falcons and Rough-legged Hawks.  The first case of LBH Syndrome was reported in Washington state in 1997 and reports have been increasing since.   This is what a normal Red-tailed Hawk’s bill looks like – quite a dramatic and obvious contrast to the diseased one.  The cause of this condition is unknown, though research is ongoing. A sad situation for this poor bird. More info here. Ron Addendum:  I posted one of these photos on a nature phography forum and a veterinarian with many years of experience with falconry birds has stated unequivocally that this hawks condition occurred because it was “kept jessed and tethered by someone who was totally ignorant of the necessity to keep the upper and lower bill trimmed to normal shape”.   Whatever the true cause of the deformity, it’s…

Bald Eagle Nictitating Membrane

The nictitating membrane (nictitan) is a membrane or “third eyelid” found in some vertebrates that can be drawn across the eye for protection and to moisten and lubricate the surface of the eye. It is either translucent or semi-transparent so the animal maintains sight while it covers the eye.    Birds, sharks and some reptiles have a fully functional nictitating membrane while in most mammals there is only a small vestigial remnant in the corner of the eye.  However camels, polar bears, seals, aardvarks, marsupials and monotremes do have fully functional membranes.   1/2000, f/8. ISO 500, 500 f/4, 1.4 tc This nearly adult (head not yet completely white) Bald Eagle is neither tame or captive.  But for several days in 2009, beginning on a bitterly cold Christmas morning, this adult adopted a favorite perch (a relatively short pole) that looked out over a pond with fish in it.  The pole was so close to the road that I sometimes had to take off my teleconverter to get the entire bird in the frame.  It warmed my heart that the eagle was so comfortable with me this close and that was a very good thing because Mia and I almost froze to death over the many hours of photographing this magnificent bird. This is the normal appearance of the Bald Eagle’s eye.  In adult birds, eye color is typically some shade of yellow with a distinctly visible pupil (though juvenile birds have much darker eyes).         1/2000, f/8. ISO 500, 500 f/4, 1.4 tc But every few seconds the bird swipes the nictitating membrane across the…

Red-tailed Hawks of Utah’s West Desert

Red-tailed Hawks are common and widespread throughout most of North America but I typically find them to be wary and difficult subjects to approach and photograph.  However we did have some pretty good luck with them a couple of mornings this past week in western Utah.   Canon 7D, 1/2000, f/6.3, EV -0.67, ISO 640, 500 f/4, 1.4 tc We found them deep in a canyon of one of the many “island mountain ranges” of Utah’s west desert.   There were at least a half-dozen of them hanging out together, many of them juveniles.  The lighting at the bottom of the canyon in early morning was often filtered and spotty and the perches were usually dead trees with lots of branches going every which way so the backgrounds and settings were typically busy.  This is one of the cleaner shots I got of one on a perch in the canyon bottom.      Canon 7D, 1/2000, f/6.3, ISO 640,EV -1.00, 500 f/4 This one chose a juniper perch which would provide a clean background for a takeoff shot so I tried to leave room in front of the bird just in case.  I was looking slightly down on the hawk when it launched and I liked the good look at the topside of the bird in this shot but do wish it had been looking more my way.  But then I probably wouldn’t have any light on the eye – sometimes you just can’t win…     Canon 7D, 1/1250, f/6.3, ISO 640  EV +0.33, 500 f/4 Shooting these hawks in flight was very frustrating!  Each morning they would pretty much…

American Kestrels – What They’ll Eat and What They Won’t.

 I’ve always found it fascinating to watch these little falcons eat.  A gruesome experience to be sure but so much more interesting than observing a raptor such as an owl who simply swallows its prey whole.  And if you watch carefully there’s a whole lot more going on during the process than first meets the eye.  Kestrels can be pretty picky eaters.  I’ve documented in another post on this blog that they often refuse to eat the intestinal tract of their prey and deliberately discard it.  Kestrels, like other raptors, eject pellets of indigestible materials like fur, feathers, chitin and bone.  All food that is swallowed first goes to the crop.  From there the usable food continues on to the stomach but the indigestibles stay in the crop, are formed into a pellet and regurgitated roughly 23 hours (in the case of kestrels) after the meal was consumed.    Canon 7D, 1/800, f/7.1, ISO 640, 500mm f/4, 1.4 tc The kestrels I’ve watched eating voles and mice typically eat the brain, decapitate the rodent, then go for the soft internal protein rich muscles and other organs (discarding the intestines).   Since kestrels tear their prey into bite-sized pieces they can pick and choose what they actually swallow.      Canon 7D, 1/400, f/8, ISO 640, 500mm f/4, 1.4 tc Pellet expulsion can be difficult and traumatic as I’ve documented elsewhere on this blog with Northern Harriers and I suspect that’s one of the reasons that kestrels try to avoid swallowing as much fur as possible.  When opening up the body cavity they often get a beak-full of…

Northern Harrier Struggling to Expel a Pellet

  Except for owls, all raptors have a crop for excess food storage.  The parts of the prey that are indigestible are formed into a pellet in the gizzard and then regurgitated out of the mouth.  These pellets contain hair, feathers, exoskeletons and sometimes (in the case of owls especially) the bones of their prey.  I’ve noticed with many raptor species that expelling a pellet can be a difficult process, bordering on traumatic.  Such was the case with this juvenile male Northern Harrier. I was watching this bird through my lens but not planning on getting any quality photos because the bird was strongly side-lit.   But when he began trying to expel a pellet I couldn’t resist clicking away.  Because of the side-lighting and relatively soft focus the images are not of high quality but I thought the behavior was interesting enough for a blog post anyway.  All of the photos in this series are posted in the order that they were taken.    The beginning of the struggle to expel the pellet    Here the harrier is shaking his head from side to side to try to dislodge the pellet   But with the effort he begins to lose his balance on the perch    And almost falls  over backward    He begins to recover    And then falls forward    Begins to recover again    Still recovering    Recovered, but still with the pellet stuck in his mouth    And finally the pellet has been expelled.  As luck would have it my buffer had filled up and I missed…

The Bald Eagle and the Fish Hook

  Last week while looking for Golden Eagles to photograph in the Promontory area at the north end of the Great Salt Lake we came across a group of adult and juvenile Bald Eagles feeding on a sheep carcass.  The light angle was bad for photography but we couldn’t resist taking a few shots anyway.    Bald Eagle with fish hook in bill We were quite close to one adult and when it flew off I instinctively fired off a few shots, despite the poor light.  When I got home and looked carefully at those images I could clearly see this gold fish hook embedded in the base of the eagle’s bill.  This bird was apparently feeding normally and I suspect that the hook will not cause it significant problems while it’s in Utah for the winter feeding on carrion.  However I am concerned that, because of the position of the hook in front of the eyes, the hook will interfere with effective forward vision for fishing after it heads north in March.  I hope it falls out or rusts off before that although I’m not sure if “gold” fish hooks rust at all. An internet search shows that fish hooks are an ongoing problem for both Bald Eagles and Ospreys.  Ron

Bald Eagle Serendipity

  This is another blog post that will be more about the experience of the photographer than about the quality of the images. My good friend Mia and I spent two days this week looking for eagles – both Bald Eagles and Golden Eagles.  We found several of each species but it was a frustrating experience – driving large distances (over 500 miles) and then having bad light, bad luck, bad timing and lots of fog.   Then, an unexpected surprise!   Bald Eagle waiting for us to get home Immediately after getting home I noticed several neighbors down the street looking up in the direction of the large elm tree in my side yard.   I ignored them at first but they persisted in staring so I followed their gaze and couldn’t believe what I saw toward the top of the tree – an adult Bald Eagle!  I live in suburban Salt Lake City and have never seen an eagle in my neighborhood in almost 25 years.   Of course, both Mia and I got out our photo gear and spent the next hour or so photographing the bird.  It was challenging to get good images because of the steep angle and the fact that the eagle was buried in the tree with branches in front and all around.  There were a few angles where we could get an almost unobstructed look at the bird but even then the background is very busy and there are shadows on the eagle.      Wing stretch The eagle was very relaxed in our presence, even…

Rough-legged Hawk – Defensive Posture

Most birds are defensive of their territories and space and raptors are certainly no exception.  Rough-legged Hawks and Northern Harriers both prey heavily on voles (mice-like rodents) so when a new bird of prey comes in to the established hunting territory of another there are often conflicts, with the established bird attempting to drive off the interloper to avoid competition for food resources.    Rough-legged Hawk As I was photographing this Rough-legged hawk sitting peacefully in a tree I noted a definite change in its demeanor so I looked around and spotted a Northern Harrier speeding toward the hawk from my right.  I anticipated that the harrier would “buzz” the roughie and since I was much too close to get both birds in the frame when it happened I decided to concentrate on the reaction of the hawk as the interaction occurred.  I never did get the harrier in the frame in any of the shots.   In the image above, the roughie hasn’t yet seen the harrier coming in (nor have I).     The incoming Northern Harrier has been spotted When I noticed this posture change in the roughie I knew something was up, so I looked in the direction the bird was focused on and saw the harrier coming in fast.       Beginning to react Here the hawk is beginning to react to the swift and aggressive approach of the harrier by beginning to fluff up.       Defensive posture This shot was taken when the harrier, traveling very fast, was closest to the hawk – roughly three…
