Short-eared Owl Taking Off In Low Light

This male Short-eared Owl was taking off from the sagebrush plains of Montana’s Centennial Valley. 1/1600. f/5.6. ISO 800, 500 f/4, 1.4 tc, natural light, not baited, set up or called in I got three shots in the sequence that I liked well enough to keep. At lift-off he was heading mostly in my direction. I was shooting from my pickup and the vehicle didn’t intimidate him in the least. 1/2000. f/5.6. ISO 800, 500 f/4, 1.4 tc, natural light, not baited, set up or called in Almost immediately he began to veer off to my left… 1/1600. f/5.6. ISO 800, 500 f/4, 1.4 tc, natural light, not baited, set up or called in and then gave me a side view as he flew off to hunt voles for his family (female and two chicks). I’ve never posted this sequence before because the very low light forced me to shoot at ISO 800 which is really pushing it for my Canon 7D so there’s some resulting noise in the images. I don’t like to use noise reduction but I’ve applied it to the backgrounds only for this presentation. Like I said in my last post, every image has strengths and weaknesses and the low light I was dealing with (especially for flight shots) forced me into some compromises for these images. They may not be perfect but I’m still happy to have them. Ron

Short-eared Owl In A Snowy Setting

I’ve had very few good opportunities with Short-eared Owls in winter but yesterday morning along the causeway to Antelope Island my luck changed a bit for the better. It was overcast but there was almost 6″ of fresh snow on the ground which helped slightly by reflecting some of the available light onto the bird. The setting in these three images is “high key” (light color tones with little contrast) because of all the snow. The background is the snow-covered lakebed of the Great Salt Lake. High key images don’t appeal to everyone. 1/2000, f/5.6, ISO 640, 500 f/4, 1.4 tc, natural light, not baited, set up or called in Northern Harriers and Rough-legged Hawks often hunt the causeway so when I first came across this owl my camera settings were already set for possible flight shots. I snapped off a few images at those settings before I made adjustments. I wasn’t particularly happy with the vegetation in front of the bird… 1/500, f/8, ISO 500, 500 f/4, 1.4 tc, natural light, not baited, set up or called in but it soon flew a few hundred feet west along the causeway and perched on a rabbitbrush that gave a slightly better view of the owl. For this shot I had maneuvered my position to get some very out of focus vegetation in the mid-background to provide at least a little bit of color back there but the difference is only slight. 1/500, f/8, ISO 500, 500 f/4, 1.4 tc, natural light, not baited, set up…

Brood Patch In A Female Short-eared Owl

One of the primary functions of feathers is insulation and they’re very good at preventing heat loss. But this efficiency presents a problem – how to keep the egg(s) sufficiently warm during incubation, since feathers act as a barrier to heat transfer from parent to eggs. Typical bird body temperature is about 104 degrees F. and the ideal incubation temperature for their eggs is very close to normal human body temperature – 98.6 degrees F. That dilemma has been solved by most bird species through the evolution of the “brood patch” – an area of belly skin that loses its feathers near the end of the egg-laying period. As the feathers are lost, supplementary blood vessels engorge the skin of the “patch” so that hot blood is brought to the surface. Amazingly, the parent can even shut down blood flow to this region when that bird is off the nest. When the incubating parent returns to the eggs for incubation, he/she typically goes through settling movements that bring the brood patch into gentle contact with the eggs. The patch may be large or small, depending on a variety of factors including how many eggs are incubated. Some species have a single patch in the middle of the belly, others may have one each side or even three. Typically the patch is difficult to observe in wild birds, particularly in flight but I have several images of a female Short-eared Owl where it is visible. This female had two chicks that she was trying to keep warm during a typically cold Montana spring. The male…

Delivering Food For A Family Of Short-eared Owls

I try not to play favorites when it comes to bird subjects for my photography but Short-eared Owls would have to be near the top of any such list I might make. I’ve had some luck with them here in Utah but my favorite area to photograph them is in southwest Montana. This series is from the summer of 2010 in Beaverhead County. I spent several days watching and photographing a male owl hunt voles and then bring them in for his family (female and two chicks) at the nest at the base of a sagebrush. I thought it might be interesting for some to see a full series of shots (of those I kept) as the male approached the nest with a vole. 1/1600, f/6.3, ISO 800, 500 f/4, 1.4 tc, shot from pickup window, natural light Like me, this male was a creature of habit. I would watch him hunting far off in the distance and when he was successful he would always repeat the same pattern. He would bring the vole in to the vicinity of the nest and then land on one of two favorite perches for a short time before delivering the vole to his family. This small sagebrush was one of those favorite perches – the other was a metal post. Here, he is in the process of landing and you can see the dark vole in his left foot. He always carried the vole to the perch in his left foot (as I’ve documented here) and always transferred…

Short-eared Owl In Flight, With Prey

I’ve been frustrated by this species in flight in Utah for years, though I’ve had some luck with Montana birds. 1/3200. f/6.3, ISO 500, 500 f/4, 1.4 tc Finally, last summer, I found a mated pair on Antelope Island who were busy trying to keep track of and feed at least four juveniles spread out over several acres. Occasionally one of the parents would fly by relatively close as it returned with a vole for the youngsters. In larger versions of this image there’s a catch light in the eye of the vole but it’s impossible to see at this size. Ron

Short-eared Owl Displaying Ear Tufts

Short-eared Owls are always a primary photographic quarry for me whenever I visit the Centennial Valley in sw Montana but on this last trip I only found one. However, that lone bird made up for it by showing me something fairly unusual. 1/1600, f/5.6, ISO 500, 500 f/4, 1.4 tc These owls have short ear tufts (“ears”) but they are only rarely seen because they are usually laying down on the top of the head. Here they can be seen, but just barely. 1/2000, f/5.6, ISO 500, 500 f/4, 1.4 tc However, when the bird turned to face me for just a moment the tufts became visible. Typically they are only erected in a defensive pose and I don’t know if this owl deliberately displayed them to me because it thought I was too close or if a breeze from the back lifted them involuntarily. I suspect it was the latter because in the shots right after this one other feathers on the head look to be blown erect by the breeze. Either way I was glad to see the tufts. I have hundreds of images of this species and very few of them show the “ears”. Ron

Short-eared Owls In Flight

These three images are of a mated pair of Short-eared Owls taken two years ago at Red Rock Lakes National Wildlife Refuge in southwest Montana. 1/1250, f/5.6, ISO 800, 500 f/4, 1.4 tc This is the male delivering a vole to his family. As you can see from my techs I had to max out my settings (especially on the last two images) to try to get enough shutter speed for flight shots. Each of these photos was taken on different mornings but the light was consistently a challenge while we were there. 1/800, f/5.6, ISO 800, 500 f/4, 1.4 tc This is the elusive female. I got very few shots of her because she spent most of the time on the nest with her two chicks and I rarely saw her fly. 1/800, f/5.6, ISO 800, 500 f/4, 1.4 tc Another look at the male. There’s a good reason for the timing of this post – we’re at Red Rock right now (I prepared this post before leaving and post-dated publication) and anticipation of this trip had me thinking about these wonderful owls again. We’d have to be pretty lucky to find cooperative owls again but if not there should be plenty of other birds to work with. The biggest challenge on this trip is likely to be light. Red Rocks is right on the continental divide and early summer weather up there is volatile and often down-right scary – especially when you’re pulling a camping trailer over 30 miles of dirt roads! These trips are…

Short-eared Owl Hunting From A Post

We were driving out of Red Rock Lakes National Wildlife Refuge on our way home when we spotted this Short-eared Owl perched on a large double post at the top of a long, grinding hill. I was pulling the camping trailer so we made a lot of racket and raised a huge cloud of dust on the gravel road so I figured there was no chance this bird would let that big noisy rig close enough for decent shots. But it did – though just barely. 1/1000, f/7.1, ISO 640, 500 f/4, 1.4 tc Here it was trying to decide if we were enough of a potential threat to fly off but soon it relaxed and seemed to accept our presence. 1/1000, f/7.1, ISO 640, 500 f/4, 1.4 tc Almost immediately the owl began to scour the slope to the right for potential prey. 1/1000, f/7.1, ISO 640, 500 f/4, 1.4 tc When it spotted something it took off… 1/1000, f/7.1, ISO 640, 500 f/4, 1.4 tc gained speed as it descended down the relatively steep slope… 1/1000, f/7.1, ISO 640, 500 f/4, 1.4 tc and this is the last decent shot I got as it got close to the grasses and I lost focus on the bird. 1/1000, f/7.1, ISO 640, 500 f/4, 1.4 tc But the owl obviously liked that post as a hunting platform and almost immediately returned to it (though these last shots are from an earlier sequence). It very quickly spotted what was probably…

Short-eared Owl Delivering Food To The Nest

In previous posts (here, here and here) about these Short-eared Owls at Red Rock Lakes National Wildlife Refuge I’ve shown and described snippets of the fascinating behaviors I observed when this male would deliver voles to the female and two youngsters at the nest. But it struck me that I’ve never put the whole process together in sequence so the behaviors could be fully appreciated so that’s what I’ll attempt to do here. Most of the images will be different from those in the previous posts. 1/1250, f/5.6, ISO 800, 500 f/4, 1.4 tc The male was a tireless and highly skilled hunter and I never saw him with any prey other than voles. When successful he would always return to the vicinity of the nest and land momentarily on one of two favorite perches – the dark sagebrush at lower right in the above photo or a metal post a few feet from the sagebrush. Here he’s coming in for a landing on the sagebrush with vole in talons and glances up at me to make sure all is safe. I really like the intense direct eye contact in the shot. 1/1000, f/5.6, ISO 800, 500 f/4, 1.4 tc Now he’s focused on the sagebrush in order to make a successful landing. 1/1250, f/5.6, ISO 800, 500 f/4, 1.4 tc This time he stayed perched for less than five seconds and didn’t even pull his wings in against his body – he just kept them out or up while he seemed to contemplate his next…

Just A Shot That I Like… #17 – Short-eared Owl In Flight With A Vole In Its Beak

This is another image from my time with the Short-eared Owls at Red Rock Lakes National Wildlife Refuge. This male was kept very busy hunting voles and feeding his mate and youngsters at the nest. Typically I would see him hunting far off, dive for a vole, and if he was successful he’d occasionally eat the vole himself but most often he would return with it to a favorite perch in the vicinity of the nest – and without exception he would always carry the vole in his talons before he got to the perch (and always his left talon, but I covered that topic in another post). 1/1600, f/5.6, ISO 800, 500 f/4, 1.4 tc However, just before (or just after) he took off from the perch to deliver the meal to his family he would always transfer the vole from his talons to his beak. I have a theory as to why he did so. The nest was on the ground at the base of a sagebrush. Whenever the male landed at the entrance to the nest with the vole the female would rush out and very aggressively grab the vole. And I DO mean aggressively! If I’d been him I’d have been afraid to get that close to her with food. So the male would approach the nest very gingerly with the vole in his beak and drop it in front of him and quickly retreat as she rushed out. I suspect it was easier for him to avoid a confrontation with her if he could quickly drop…

Just A Shot That I Like… #6 – Short-eared Owl In Flight With Prey

Sometimes conditions are marginal at best for avian photography and that often seems to be the case for me when I’m presented with an otherwise wonderful opportunity. Then the decision must be made – go ahead and shoot anyway, knowing it’s likely that I won’t get any keepers or just pack it in and watch and enjoy the birds? 1/640, f/5.6, ISO 800, 500 f/4, 1.4 tc, noise reduction to background Such was the case with this Short-eared Owl at Montana’s rugged and remote Centennial Valley. It was an overcast day and there generally wasn’t enough light for photographing birds in flight but this male was regularly delivering voles to his family and would occasionally fly right by me as he did so. I could have removed my teleconverter to get a little more shutter speed but then the owl would be quite small in the frame so I just decided to fire away and hope for the best. Even at ISO 800 (the absolute limit for my 7D without getting too much noise) I was often getting shutter speeds of 1/500 or slower at f/5.6 – just not fast enough to get birds in flight sharp. I got lucky with this shot. As the owl was coming in, the clouds behind me opened up slightly to allow a little more light on the bird and a shutter speed of 1/640 – just enough to get good sharpness on a relatively large and slow flying bird if your focus is well locked on to the subject. The still shaded Centennial Mountains provided…

Raptors Mobbing Raptors

Mobbing is an antipredator behavior where animals mob a predator by cooperatively attacking or harassing it. This behavior is especially common in birds during nesting and rearing of young. Typically, it will be a flock of passerines like Red-winged Blackbirds mobbing a raptor or perhaps a magpie or any other bird they consider to be a threat to their nest or young. In mid-June of this year while Mia and I were on another one of our camping/photo forays to Red Rock Lakes National Wildlife Refuge we witnessed a somewhat unusual display of mobbing – raptors mobbing raptors. We had just returned to our camping trailer when Mia noticed this sub-adult Bald Eagle resting on a muskrat mound almost a quarter-mile away across Lower Red Rock Lake – too far away for quality photos (we had marginal light too) but we simply can’t resist training our lenses on a situation like this just to see if something interesting might happen. And this time it did. Canon 7D, 1/800, f/6.3, ISO 500 ev +1.33, 500 f/4, 1.4 tc The eagle seemed to be minding its own business and just hanging out for a while on the mound. Canon 7D, 1/640, f/6.3, ISO 500 ev +1.33, 500 f/4, 1.4 tc But soon a Short-eared Owl (a male I believe) appeared on the scene and he was not happy with the presence of the eagle. My presumption is that the owl had a nest in the area and it felt the eagle threatened the nest or young. Canon 7D, 1/1000, f/6.3, ISO 800 ev +1.00,…

Short-eared Owls Defending Their Nest Against Predators

Recent reports from others indicate that bird activity on Antelope Island is slowing down now and our experience out there recently would agree with that assessment so yesterday when Mia and I were trying to decide where to go shooting birds we were a little hesitant about another trip to the island. But even with things slowing down we almost never fail to find something interesting to photograph and yesterday was certainly no exception! Canon 7D, 1/800, f/7.1, ISO 500, EV 0, 500 f/4, 1.4 tc Soon after arriving on the island we noticed a pair of Short-eared Owls, obviously mated based on their behavior. Canon 7D, 1/1000, f/7.1, ISO 500, EV 0, 500 f/4, 1.4 tc This owl was carrying a vole and we immediately suspected that the pair had a nest in the vicinity, which turned out to be true. It was quite a distance from the road and buried in vegetation but we could tell its location by watching this owl deliver food to the nest site – either to the mate or to both the mate and chicks. We watched and photographed the birds for a while but when things slowed down we went further down the island. Canon 7D, 1/1600, f/8, ISO 640, EV + .67, 500 f/4, 1.4 tc On our return to the area of the nest we immediately saw a quickly developing drama. A young coyote had apparently just crossed the road and was approaching the nest area and the owls were in…

Agonistic (fighting) Behavior in Male Short-eared Owls

I recently returned from one of my favorite places in the world – Red Rock Lakes National Wildlife Refuge. Last year I was able to photograph nesting Short-eared Owls carrying voles to their young but this year, because of the very cold spring, nesting hadn’t even begun. Instead the owls were competing for territory and mates and pairing up. On one morning I was incredibly lucky to find two males trying to impress a female with their aerial prowess and fighting skills. They were so engrossed in their activities that they pretty much ignored me. Canon 7D, 1/2000, f/7.1, ISO 500, 500 f/4, 1.4 tc Often one male would be on the ground when the other male would swoop in on him. Here the foreground bird has just lifted off to meet his adversary. Canon 7D, 1/2000, f/7.1, ISO 500, 500 f/4, 1.4 tc As was often the case the birds didn’t make actual contact. In researching this behavior I’ve learned that they will sometimes lock talons and fall to the ground before releasing. I suspect that as they rush toward each other they look for a weakness in defense – if they spot one in the other birds defensive body position they would likely make aggressive contact. Canon 7D, 1/2000, f/7.1, ISO 500, 500 f/4, 1.4 tc Most of the time both birds stayed on the ground or flew very low but occasionally one of the owls would fly several hundred feet up and circle over the other male (and the female, who was…

Short-eared Owl in the Fog

My friend Mia and I had such a great time in June with the Short-eared Owls at Red Rock Lakes National Wildlife Refuge in Montana that we decided to return in September. Getting close to them was more difficult this time because they weren’t nesting and feeding young. However, one morning we got lucky. A cooperative Short-eared Owl When we awoke we were socked in with heavy fog. As it slowly began to clear we went looking for birds and found this owl perched in the middle of the road. As we approached, it flew a short distance to this post and then allowed us to get very close. We’re sure this is the same female that we had photographed in June on the same territory. Short-eared Owl female looking for voles She was very accepting of our presence and within a few minutes was looking for voles below her post perch. We were right at the edge of the fog and as it would swirl around us, alternately getting thicker and then clearing a bit, we knew that some of our images would show the effect of the fog more than others. The soft feathers of owls don’t give up their fine detail to photographers easily, even in the best of conditions. But we simply couldn’t pass up this opportunity with this beautiful female and we still got some shots we like very much. Short-eared Owl checking us out Occasionally her attention would be diverted from the potential prey in the…
