Anticipating The Return Of Rough-legged Hawks

Rough-legged Hawks are a true arctic species, spending about 7 months of the year on their breeding grounds in the arctic or sub-arctic tundra or taiga of Alaska or Canada. Then they migrate south and winter in most of the lower 48 states, with the exception of the SE region and parts of California and Arizona. I love it when they’re here as I find them to be exceedingly handsome birds and I really enjoy photographing them. And yes, I’m already looking forward to their return. Every time I’m in their favorite haunts I can’t help looking for them on some of their preferred perches, even this time of year. So, feeling a little nostalgic for them on a Saturday night, I thought I’d do a post on the species. 1/2000, f/6.3, ISO 500, 500 f/4, 1.4 tc, natural light, not baited, set up or called in Normally I’m not terribly fond of the Tintic Quartzite rocks on Antelope Island as perches because they’re so bright that they tend to blow out the whites but as you can see by the shadows the sun was still very low when this shot was taken so I got pretty good detail on most of the perch. And besides, I like the rounded, weathered look of this particular boulder. I do wish the out of focus sunflower heads in the foreground weren’t there but for me they’re not an image killer. 1/2000, f/7.1, ISO 500, 500 f/4, 1.4 tc, natural light, not baited, set up or called in This is one of…

Red-tailed Hawk Banking At Take-off

This morning I’m off on a new adventure, looking for birds (raptors in particular) in a spectacular area I’ve never visited before so I only have time for a short post. In past years I haven’t had great luck with Red-tailed Hawks, even though they’re one of the most common raptors in Utah. They always seemed to be perched on telephone poles, which makes for an unattractive perch and unacceptably high angle. Even at take-off I’d generally only get blue sky backgrounds which I don’t find particularly interesting. But in the last couple of months my fortunes with the species have changed. 1/2500, f 7.1, ISO 500, 500 f/4, natural light, not baited, set up or called in Yesterday morning this juvenile was sitting on an elevated perch and facing away from me, which didn’t give me high hopes for a take-off shot. But it spotted potential prey over its shoulder so when it launched it turned back toward me in the process. I liked the result. The yellows in the background are sunflowers and blooming rabbitbrush. I removed a portion of the unattractive perch in the lower right corner of the frame. Cloning is something I nearly always avoid doing but in this case I made an exception. I mention it in the interest of full disclosure. I’ll make another post soon that will also feature this bird but it will have an interesting “twist” from my usual fare. Ron

Getting Close To The American Kestrel

One of the first lessons bird photographers learn (often to their great frustration) is that you must get close to your subject in order to get good detail. Very close. Even if you’re shooting with a long, expensive lens. And getting close usually ain’t easy! Large crops rob detail. I’m of the opinion that cropping away any more than about 50% of the image generally does unacceptable damage to image quality. Some species are relatively easy to approach – around here American Robins, Mourning Doves and House Finches come to mind. Other species have a reputation of being particularly skittish and at the top of that list for many photographers is the American Kestrel – a strikingly beautiful little falcon that is found throughout most of North America. For many years I’ve posted bird images on an internet avian critique forum and whenever I’d post a shot of a kestrel I’d invariably get comments that went something like this: “How in the world did you ever get this close to a kestrel? I always see them perched up high on poles or wires and whenever I even begin to get close they fly away”. Well, here’s the secret – photograph them when it’s cold. Very cold! That means in the depths of winter. It also means in the early mornings on those days when it’s coldest of all. I’ve found that many species of birds are more reluctant to fly in the cold but that tendency seems to be magnified with the kestrel. I’m not sure why but as a photographer I’m more than happy to…

Red-tailed Hawk Rejecting Intestines Of Prey

Many raptors will methodically and deliberately remove the intestinal tract of their prey before consuming it, a behavior that I’ve photographed several times with different species. In my research I’ve never been able to find out exactly why this is done – there are multiple theories but apparently no definitive answers. Maybe they tend to reject them because they “taste bad”, or because they “harbor harmful bacteria” or because they are filled with contents that are of “low food value”. Perhaps it’s a combination of factors. Recently, to add to the confusion, I’ve come up with my own working theory. The intestines of vertebrates, particularly mammals such as the rodents that many of these raptors regularly prey on, tend to be infested with a variety of parasites – including worms such as intestinal roundworms, flukes and tapeworms. The life cycles of many of these parasites are convoluted and complex but some of them lay thousands of eggs into the hosts intestinal contents every day. Eating those contents could have unpleasant consequences for predators so it seems logical to me that selection pressure might preserve such a behavior. 1/1000. f/5.6, ISO 640, 500 f/4, 1.4 tc, natural light, not set up, baited or called in While I was in SW Montana a few weeks ago this juvenile Red-tailed Hawk flew to a nearby post with a vole and started to eat it. It began by opening the vole and then removing and swallowing several desirable morsels. Here you see an errant feather floating away in the breeze. 1/1000. f/5.6, ISO 640, 500…

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…

Escaped Falconry Bird – Peregrine Falcon

Early this morning, just as the sun was coming up over the Wasatch Mountains, we came across this adult Peregrine Falcon, with prey, along the causeway to Antelope Island State Park. It is apparently another escaped falconry bird as it had obvious falconry anklets above its feet, though the actual jesses had been removed. 1/500, f/5.6, ISO 640, 500 f/4, 1.4 tc This first image was taken where we first found it – along the edge of the causeway and next to the Great Salt Lake shoreline. A few seconds after this shot was taken the bird took off. 1/800, f/5.6, ISO 640, 500 f/4, 1.4 tc But seven minutes later, as we proceeded along the causeway, we found the bird perched on this highway post. 1/1000, f/5.6, ISO 640, 500 f/4, 1.4 tc This shot was taken as the falcon took off from the post. You’ll notice that the leather falconry anklets, sans jesses, are apparent in each of the above three images. 1/2000, f/5.6, ISO 640, 500 f/4, 1.4 tc And the last time we saw the bird it had landed far away on the large boulders lining the east side of the Antelope Island Marina. We’ve reported this sighting to the Utah Division of Natural Resources and they’ve told us that they will follow up on it. I’ve always admired the sport of falconry on several levels. Falconers generally have a deep devotion and personal attachment to their birds that I respect and they and their organizations have done a lot for raptor conservation…

Landing Red-tailed Hawk

I haven’t often succeeded in photographing a landing raptor. When they take off they usually don’t come back and when they do it’s often difficult to maintain focus on them as they land because of close backgrounds. However, this immature Red-tailed Hawk gave me just such an opportunity a couple of days ago. 1/2000, f 7.1, ISO 500, 500 f/4 It was hunting from a huge rock outcropping and looking down over the valley in the background of this image. I spent quite a while with this bird but it was side lit and I wasn’t very optimistic about getting a decent take-off shot because I expected it to spot potential prey in the valley below and take off away from me, giving me butt shots only. 1/1600, f 7.1, ISO 500, 500 f/4 Which is exactly what happened. However, I saw where the bird landed far below in the valley, missed the prey and took off again so I wondered if I could be lucky enough for it to return to the same perch. I wasn’t particularly optimistic because I was so close to the rock (you’ll notice from my techs that I had even removed my tc). The problem was that as soon as the hawk took off from that distant perch it disappeared behind the same massive rock outcropping on the side of the mountain that had been its perch and if it did return I wouldn’t know it until the very last split second, as it flared up to land on the rock from behind and below it. So I prefocussed on the likely…

Swainson’s Hawks Of Montana’s Centennial Valley

On my trip to Montana’s Centennial Valley last month Swainson’s Hawks were very abundant. I found two families of them that would reliably hunt close to a road and since they had become habituated to the traffic they were easier for me to approach as long as I stayed in my pickup truck. 1/1000, f/7.1, ISO 500, 500 f/4, 1.4 tc This was one of two juveniles along the river at the west end of the valley. Both birds, along with their parents, would repeatedly perch on posts and poles close to my pickup. But it was very difficult to get an acceptable light angle at this location in the morning so I include only this one shot of those birds. 1/2000, f/6.3, ISO 500, 500 f/4, 1.4 tc I had more luck with another family (two juvies and one parent) at the east end of the valley. The light angle was better and I also preferred the fence posts in this area – they were older and had more character. 1/500, f/11, ISO 500, 100-400 @ 400mm Occasionally I was able to get both juveniles in the same shot but of course that situation often brings with it a depth of field problem so I switched to the 100-400 zoom and set my aperture at f/11 and focused on the post between the two birds. It seemed to work pretty well. 1/2000, f/6.3, ISO 500, 500 f/4, 1.4 tc I loved the “butterscotch” colors on these two juveniles – particularly this one. 1/2000,…

Juvenile Red-tailed Hawk Take-off

Recently I’ve had several opportunities with a pair of Juvenile Red-tailed Hawks that like to hunt from some elevated rocks that look down over some prime rodent habitat. It’s nice for a change to find them on natural and attractive perches rather than telephone poles or even fence posts. Don’t get me wrong, I like a rustic old fencepost as a perch but I do enjoy these natural rocks for a change. 1/8000, f/5.6, ISO 640, 500 f/4, 1.4 tc (inappropriate techs for this shot, hadn’t had time to change them yet) The birds scan the grasses below them for prey and if you watch their behavior and body language carefully you can anticipate take-off. 1/2500, f/7.1, ISO 640, 400 f/4, 1.4 tc I could tell this bird had spotted potential prey below (a vole, most likely) so I was ready to fire off a burst as it launched. I’m always happy when I can get a wing position like this one. 1/2500, f/7.1, ISO 640, 400 f/4, 1.4 tc In the very next frame of the burst I got a similar wing position as it lifted off of the rock and luck played a significant role in that fact. The burst rate of my Canon 7D seems to be just about the same speed as that of the wing-beats of raptors this size as they take off, so there was a very good chance that the wings in both shots would be in the much less desirable horizontal position. Sometimes things work out, sometimes they don’t. Observing and photographing these two birds has…

Goofy Red-tailed Hawk

When I first encountered this juvenile Red-tailed Hawk in Beaverhead County three weeks ago it was eating a vole on top of this fence post. Soon after it finished the rodent it began to act a little strange. 1/2000, f/6.3, ISO 640, 500 f/4 In these first few shots it may look like the hawk is simply shaking or “ruffling” its feathers but I’m convinced that wasn’t the case. I’ve seen many birds perform that feather maintenance activity but what was happening here looked quite different. I remember telling Mia while it was occurring that it looked like the bird was “dancing” on top of the post. 1/2000, f/6.3, ISO 640, 500 f/4 The hawk went through some strange gyrations and postures that were different from what you see with a simple “shake” and they lasted an unusually long time (I have many shots of the behavior). This tail-up posture, for example, is reminiscent of defecation but the bird didn’t defecate and the wing position isn’t what you would normally see during defecation anyway. 1/2000, f/6.3, ISO 640, 500 f/4 The bird wasn’t shaking to get these unusual feather positions either – instead it seemed to be deliberately and relatively slowly (compared to shaking) erecting its feathers. I have 8 – 10 shots that are very similar to this one and they’re not all in sequence. 1/1600, f/6.3, ISO 640, 500 f/4 Then the bird decided to take off from the post… 1/2000, f/6.3, ISO 640, 500 f/4 but…

Male Northern Harrier Almost Blown Off His Perch

I don’t often get close to perched male harriers but on Antelope Island a couple of months ago this one made an exception for me. 1/3200, f/5.6, ISO 640, 500 f/4, 1.4 tc As I watched him through my lens a sudden wind gust almost blew him off of this pointed and precarious post perch and I liked some of the poses that resulted. It’s times like this that I appreciate the relatively fast burst rate of the Canon 7D. I didn’t get a great look at the eye in this first shot but I liked the tail, wing and left foot positions that show his obvious attempt to recover stability on the perch. 1/3200, f/5.6, ISO 640, 500 f/4, 1.4 tc A better look at the eye and a higher wing position in this image… 1/3200, f/5.6, ISO 640, 500 f/4, 1.4 tc and in the very next frame he extends his left wing far out in front. 1/3200, f/5.6, ISO 640, 500 f/4, 1.4 tc Still recovering. Notice the bloody feet in these shots, most likely from his last vole meal. 1/3200, f/5.6, ISO 640, 500 f/4, 1.4 tc Finally, he’s recovered enough to give me direct eye contact. 1/2500, f/5.6, ISO 640, 500 f/4, 1.4 tc A little ruffled by the experience but in the end, all’s well. This series is an example of why, after I’ve taken a few static shots of the bird, I like to bump my settings to give me enough shutter speed…

Ferruginous Hawk On A Rustic Perch

Ferruginous Hawks are very impressive birds when you get this close to them. They are massive broad-winged hawks with a wide gape, large head and burly chest. They are our largest buteo and share many characteristics with the Golden Eagle. Last week in Montana I came across this bird on what is apparently a favorite perch – a rustic entrance gate to an irrigated farm in a small, beautiful and lush valley in Beaverhead County. I say “favorite perch” because I found this same bird (apparently) on the same gate, and in the same position, last month. 1/2500, f/7.1, ISO 500, 500 f/4 These hawks are “sit and wait” hunters, which is exactly what this bird was doing. Their preferred prey is ground squirrels and prairie dogs and based on the number of badger holes in the valley I’d guess that there’s plenty of ground squirrels available. This is another version of the same image, cropped differently and more closely to better show the group of gnats (no-see-ums) swarming around the head of the hawk (to the left, I cloned them out in the first image). In some ways the biologist in me actually prefers the second version. 1/2000, f/8, ISO 500, 500 f/4 When it took off it was facing away and I clipped a wing-tip but I decided to include this image anyway to show the bird up close and in flight.

Swainson’s Hawk Regurgitating Pellets

Western Montana has been awash in Swainson’s Hawks this summer. From the Canadian border (Glacier County) to the southern border with Idaho (Beaverhead County) I found them in significantly larger numbers than I have seen in previous summers. I hope this very unscientific observation is accurate and that it bodes them well as a species because their numbers have been declining to the point where they are listed as a Species of Special Concern in several western states. 1/2000, f/7.1, ISO 500, 500 f/4 I found this handsome juvenile this past week along a county road in Beaverhead County. At first it was very relaxed and assumed this clenched fist pose that is so typical of many buteo species when they’re at ease and resting. 1/1600, f/7.1, ISO 500, 500 f/4 But soon it began to arch its neck and I recognized that it was about to attempt to expel a pellet. I had already taken my tc off in anticipation of take-off so I decided to leave it off because so often in the past I’ve missed the falling pellet as it dropped out of frame at the bottom. 1/2000, f/7.1, ISO 500, 500 f/4 Then, with the nictitating membrane pulled over the eye, the bird began to retch. These few images showing pellet ejection may give the viewer the impression that it all happened very quickly. It didn’t. From beginning to end the whole process took over four minutes. During that time there were alternating periods of retching and resting and it didn’t look to be a…

Swainson’s Hawk Take-off Sequence

While cruising the back roads of Glacier County, Montana two days ago we came across this Swainson’s Hawk hunting grasshoppers from an old fence post. Hunting is easy now because it’s harvest time up here and the huge grasshoppers are everywhere – as evidenced by the colorful and greasy windshields of almost every vehicle you see. 1/4000, f/6.3, iso 500, 500 f/4 When the bird seemed about to take off I made one of those split-second decisions that every bird photographer is faced with. Since it looked like the hawk might launch at a 90 degree angle to my position (and stay the same distance from me for the first few flight strokes) I decided to prefocus on the bird and then not attempt to actively maintain focus in flight for fear of having focus lock on to the background instead of the bird. This time it worked… 1/4000, f/6.3, iso 500, 500 f/4 The bird begins to launch. 1/4000, f/6.3, iso 500, 500 f/4 The beginning of my burst caught the hawk in one of those dynamic, stretched-out postures that I like. As you can see the bird lost a feather as it took off. 1/4000, f/6.3, iso 500, 500 f/4 By the next wing stroke it was already to the next fence post. I got several more sharp shots as the bird passed to my left but of course the further it flew the less eye contact I had so the early shots were the best of the bunch. The Swainson’s…

Rustic Red-tail

This is another Montana Red-tailed Hawk, photographed in Beaverhead County a few weeks ago. 1/1000, f/5.6, ISO 640, 500 f/4, 1.4 tc I tend to like rustic settings like this for raptors in general but particularly for Red-tails because they have adapted so well to our rural habitats. 1/800, f/9, ISO 500, 500 f/4 This hawk was hunting from the post and changed positions on the perch several times to get a better view in different directions. 1/1250, f/7.1, ISO 500, 500 f/4 Soon the bird went into stretch mode. 1/500, f/7.1, ISO 500, 500 f/4 But eventually it spotted something of interest on the ground (and very close to me) and flew down to investigate. It didn’t find any prey and here it is looking back toward the fence – deciding which fence post to use for its next perch. 1/1000, f/7.1, ISO 500, 500 f/4 It chose another near-by post to hunt from but that hunting station didn’t last long because… 1/1000, f/7.1, ISO 500, 500 f/4 a very aggressive robin took exception to this new location. 1/500, f/7.1, ISO 500, 500 f/4 The hawk took the bombardment for a short period but eventually took off in apparent exasperation – with the angry robin continuing to buzz the raptor all the way. The more time I spend with raptors the more I realize just how much harassment they get from other bird species. At times they seem to have no peace whatsoever….
