Barn Owls On Unnatural Perches

It’s been a while since I’ve seen any Barn Owls out and about and I’m thinking they won’t be flying again during daytime until at least next winter so I decided to bid them adieu for the present with one last post for the season. I generally prefer my avian subjects on natural perches but Ingrid Tayler’s affection for birds on man-made perches in the urban landscape is beginning to instill in me a little more flexibility. Perhaps it isn’t too late for some new tricks from this old dog… 1/2000, f/7.1, ISO 500, 500 f/4, natural light, not baited set up or called in At Farmington Bay WMA there are numerous signs posted directing hunters to where they can hunt and where they cannot and those signs are favorite resting spots for hunting raptors. When I come across an owl on one of these signs I’ll typically drive on by unless there’s a possibility for take-off shots but I made an exception for this one despite the less than ideal light. 1/2000, f/7.1, ISO 500, 500 f/4, 1.4 tc, natural light, not baited set up or called in Another favorite perch is this kestrel nesting box at the top of a hill. From this elevated vantage point the birds can hunt visually over a large area without expending the energy required for flight – a significant advantage in the depths of a long, cold winter when calories are at a premium. This owl looks like it might be wary of me and about to fly, but it isn’t. It was calmly…

Short-eared Owl Tattoo – A Work In Progress

Something a little different from me this time… In the past I’ve had a wide variety of requests for use of my images, including such disparate projects as prints, magazine and book publications, non-profit scientific and educational organizations (which I nearly always allow without a fee), fancy rubber stamps, uses by painters and other artists as subjects for their work, an image to be lacquered into the top of the communal dining table of a new fire station in Temecula, California and several of my Northern Harrier (a type of hawk) images have been used in the AV8B Harrier (jump-jet) pilot training software at the Naval Air Weapons Station at China Lake, California. But a few weeks ago I got something new for me – a request to use one of my avian images for a very large, “photo – realistic” tattoo. Jenna, from New Zealand, contacted me and requested to use this image of a female Short-eared Owl in flight (with brood patch visible on the belly) as the basis for the tattoo. Her tattoo artist, Matt Jordan of Ship Shape Tattoo, Orewa, New Zealand, needed a high-resolution version of the image in order to get enough detail to make the very large tattoo photo-realistic. Even though this shot was taken in extremely low light and doesn’t have quite as much detail as most of my photos, in the end there was enough. Matt Jordan is apparently very talented and in high demand so it took Jenna several months to get the project started. It’s a long, drawn out and painful process. Jenna’s first session with Matt lasted for 6…

Short-eared Owl Perch-hunting

A couple of weeks ago I posted two shots of this Short-eared Owl perched on this frost-covered rabbitbrush. In those images the bird was reacting to me which isn’t really a natural behavior. A direct look toward the viewer from those strikingly colorful eyes is certainly riveting but more natural behaviors also appeal to me. 1/500, f/8, ISO 500, 500 f/4, 1.4 t c, natural light, not baited, set up or called in Short-eared Owls hunt primarily “on the wing” – they’re typically not “sit and wait” hunters like many other raptors. But this bird noticed what was probably a vole at the base of the rabbitbrush and its reaction to it was obvious. It stared intently down for some time which resulted in a natural pose that I like.

Juvenile Burrowing Owl Parallaxing

Parallax is the effect where the position or direction of an object appears to differ when viewed from different positions. When an observer moves, the apparent relative motion of several stationary objects against a background gives hints about their relative distance which the brain can interpret to provide absolute depth information. As you can imagine this can be very helpful to birds for flight and for judging prey position. The movement required comes automatically during flight but it can also be provided while perched by exaggerated movements of the head in all three dimensions. Tipping the head also provides cues by changing the relative position of the eyes to the object being viewed. Learning to interpret this information takes practice so many juvenile birds do just that, owls in particular. Techs for the following images – most were taken at 1/640 or 1/800, f/9, ISO 400, 500 f/4, 1.4 tc, natural light, not baited, set up or called in. All images presented in the order they were taken. Several years ago I spent a lot of time over several weeks photographing a family of Burrowing Owls along the causeway to Antelope Island. Their burrow was very close to the road and they became almost completely acclimated to traffic so I was able to observe and photograph many interesting behaviors of both juveniles and adults from my pickup. Here, this juvenile is simply ignoring me (for the sake of convenience I’ll refer to this bird as a male though I have no idea what sex it…

Great Horned Owls In The Montana Wind

I’ve posted before about the Great Horned Owls on the family farm in nw Montana. That farm is near Cut Bank, Montana which is famous (infamous) for its howling winds. 1/1000, f/8, ISO 500, 500 f/4, 1.4 tc, natural light, not baited, set up or called in So many of my images of those farm owls show the effects of the wind on the owls. The wind was only moderate when I took this shot so about the only effect you can see from it is the leaning ear tufts (horns). Even at this wind speed you can hear it whistling through the granary cutouts where these birds like to perch When I’m shooting from a tripod instead of from my pickup it’s difficult to get sharp shots because of the effects of the wind on my long lens. 1/160, f/10, ISO 500, 500 f/4, 1.4 tc, natural light, not baited, set up or called in But when the wind really howls the birds seek refuge. This owl liked to hunker down deep in this Poplar tree as an escape. It was so deeply buried in the tree that I could only get fleeting glimpses of it when the wind would blow some of the branches and leaves in front of the bird to the side. At times the wind would blow the ear tufts almost flat on its head. This owl is leaning into the wind to keep from being blown off the perch. 1/500, f/8, ISO 500, 500 f/4, 1.4…

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

A Tale OF A Barn Owl Tail

I learned something this morning. It will likely seem inconsequential to others but it was sort of a big deal for me. 1/3200, f/6.3, ISO 500, 500 f/4, natural light, not baited, set up or called in A few minutes ago, while processing this recent Barn Owl image, I was once again struck by how short and stubby the square tail of this species is, especially when compared to the length of the wings. And then some faint memory from long ago popped into my head. Bingo! Now it all made sense. 1/320, f/7.1, ISO 500, 500 f/4, 1.4 tc, natural light, not baited, set up or called in By coincidence, exactly 5 years ago today I posted this image to an online nature photography critique forum (Nature Photographers Network or NPN). At the time I was just becoming serious about my bird photography and I took the critiques I got on that forum to heart – trying to learn from my mistakes and improve my skills. In the version of the photo I submitted to NPN I didn’t recognize the “structure” marked with the red arrow as being part of the bird so I had cropped the image in such a manner that I “clipped” the tip of that structure. The critiques I got from the members of the forum “dinged” me for it, and rightfully so. They all said that I had clipped the tail and in my inexperience I assumed they were right and went on with my life. But I felt pretty silly…

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…

Nothing Wrong With A Butt Shot Now And Again…

This isn’t the sharpest image in my portfolio but it does intrigue me. A lot. Six days ago this Barn Owl made an unsuccessful plunge into the deep snow for a vole and soon after took off almost directly away from me. This is one of the images I got as it lifted off in the direction of its favorite hill-top perch – a “butt shot” to be sure but I’m fascinated by the wing angle and position. 1/3200, f/7.1, ISO 500, 500 f/4, 1.4 tc, natural light, not baited, set up or called in This shot caught the wings toward the end of the upstroke. The primary feathers at the end of the wings are in what appears to be an almost perfectly vertical position to allow for very little air resistance as they move to a higher position in preparation for the powered downstroke but the secondary feathers are pointed almost directly back at me. The skeletal structure of a bird’s wing is homologous (similar in position, structure, and evolutionary origin but not necessarily in function) to the forelimb of most other vertebrates (including humans) with a humerus, then radius and ulna, then metacarpals and finally phalanges at the end. Like humans, the joint between the radius/ulna and the metacarpals is the carpal or “wrist” joint (see here if you’re curious and/or confused by the anatomy). So the “wrist” is the joint between the primary and secondary wing feathers. Our wrist or carpal joint can be “bent” up or down and left or right but it cannot be rotated (try holding your…

Barn Owl Hunting Adaptations And Techniques

One more Barn Owl post and then I’ll give them a rest for a while. Lately I’ve spent a lot of time watching these birds hunt and I’ve become intrigued by the process and their adaptations for doing so. Hunting over deep snow presents unique challenges because their prey (typically voles) spends most of their time in tunnels under the surface, so the owls are often hunting by sound alone. According to Birds of North America Online (out of Cornell) Barn Owls hunt prey by sound more effectively than any other animal ever tested (I’m unsure if this statement takes into account the use of sonar by cetaceans and ultrasonic sounds by bats but BNA seldom gets things like this wrong). 1/3200, f/7.1, ISO 500, 500 f/4, 1.4 tc, natural light, not baited, set up or called in They fly low and slow over the surface while watching and listening but with this much snow they usually locate the voles only by sound. Notice that they can tuck their legs up into their ventral feathers so far that only the feet are visible. It’s amazing that they can do so because… 1/3200, f/7.1, ISO 500, 500 f/4, 1.4 tc, natural light, not baited, set up or called in as you can see in this “butt shot” those legs are incredibly long. This is an adaptation for grasping prey through deep vegetation or snow. Their claws (nails) are unusually long and sharp and the middle nail has a pectinate inner edge, most likely an adaptation for grasping prey…

Barn Owl Hunting Over A Hoarfrosted Hill

The Barn Owls are still hunting sporadically during daylight in northern Utah. I’ve seen them doing so in a variety of areas and heard reports of it happening elsewhere. Some areas near the Great Salt Lake are literally “magical wonderlands” in the early mornings due to the thick layer of hoarfrost that covers nearly everything. The frost falls off the vegetation during the day, then reforms during the night. The hoarfrost produces a setting for my images that appeals to me. The camera settings for the images in this post were: 1/3200, f/7.1, ISO 500, 500 f/4. The owl was not baited, set up or called in. Yesterday morning this owl was hunting along the upper edge of a steep-sided hill as it came in my general direction and then rounded the hill to my right. In the first four shots you can see that its attention is riveted to the side of the hill where the snow cover is much less deep than it is everywhere else, which would increase the chances of spotting a vole. I chose to compose these images a little differently so that the frost-covered hunting ground becomes almost as important to the image as the bird. If you have any thoughts on this composition I’d be interested in hearing them. As the bird rounded the hilltop and got closer to me the frosted vegetation became more dominant in the images. You can see that the snow on the hillside is patchy (most of the white is frost) so I believe that…

Barn Owl On A Natural Perch

I had an enjoyable day yesterday while photographing birds with Mia and Brian Gatlin, a friend from northern Arizona. Since we shoot from my pickup I was the “designated driver” and wasn’t able to do much photography but we did see a lot of great birds and I enjoyed the conversation immensely (in spite of the good-natured but merciless teasing from Mia that I endured all day…) 1/1250, f/8, ISO 400, 500 f/4, natural light, not baited set up or called in Strange as it may seem, over the years I’ve had much more success getting Barn Owl shots I like while they’re in flight than I have while they’re perched because of their tendency to land on unattractive and unnatural perches like metal posts and signs. But this owl allowed us close while perched in a tree that didn’t have too many distracting branches in the setting. Good bird! Ron

Birds Dealing With Snow And Cold

Birds use a variety of tactics to deal with the harsh conditions presented by an unusually cold and snowy winter. Some are more effective than others. I thought it might be interesting to see a few of them that I’ve been able to photograph in the last several weeks. My usual disclaimer for posts relating to behaviors; many of these images are technically lacking but I think they do illustrate some of the conditions these birds are having to cope with. 1/2500, f/6.3, ISO 640, 500 f/4, 1.4 tc, natural light After a fresh snow, the food source for many small birds is largely hidden and unavailable without some extraordinary measures. This juvenile White-crowned Sparrow, and others in the flock, were flitting from one snow-covered perch to another in an obvious attempt at knocking the snow off so they could get to the seeds underneath. Here you can see the snow falling away and immediately afterward the sparrow fed on the uncovered seeds. 1/2500, f/7.1, ISO 500, 500 f/4, 1.4 tc, natural light, not baited, set up or called in When it gets very cold most water sources freeze up completely which makes fish largely inacessable to Bald Eagles so many of them turn to scavenging as their primary food source. But this species adapted very well to scavenging eons ago which is one of the reasons Ben Franklin looked in disfavor at the proposal to make the Bald Eagle our national bird. 1/1000, f/5.6, ISO 640, 500 f/4, 1.4 tc, natural light, not baited, set up or…

Barn Owls In Flight

This is the time I’ve both looked forward to, and dreaded – when Barn Owls hunt during daytime. Normally this species is strictly nocturnal so they fly only during times that photography is virtually impossible. But around here, when it turns very cold and the snow is deep, they must continue to hunt during the day in order to survive. It’s my guess that there are two reasons for the change in behavior; the cold increases their demand for body heat and the food to supply it, combined with the difficulty of hunting voles when the snow is so deep. The last time these birds hunted regularly during daytime was several years ago when we had a similar frigid winter. Many of those birds didn’t survive until spring. 1/2000, f/6.3, ISO 500, 500 f/4, 1.4 tc, natural light, not baited, set up or called in Yesterday there were several Barn Owls hunting in mid-day soon after our latest storm began to clear out which finally allowed for some good light. It was brutally cold with perhaps a foot of fresh snow on the ground, on top of the snow from previous storms. Notice the ice/snow clumped on the feet of the owl. 1/3200, f/7.1, ISO 500, 500 f/4, 1.4 tc, natural light, not baited, set up or called in I’ve mentioned before how difficult it can be to get a catch light in this species because of their deeply set eyes. I didn’t get any light in the eye in this image but I liked the wing…

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…
