Just A Shot That I Like… #19 – Burrowing Owl Catching Its Balance
Burrowing Owls on Antelope Island are often a hit or miss proposition. Occasionally one can find an accessible burrow occupied by multiple birds and get just close enough for quality images without disturbing the owls. But more often than not they’re difficult to find – especially in a location where the angle of light is good in the morning when I prefer to shoot. 1/2000, f/7.1, ISO 500, 500 f/4, 1.4 tc This bird was one of a family of owls on the north end of the island that would occasionally sun themselves in the early morning at the top of a sagebrush perch. Here the owl had momentarily lost its balance while changing position on the branch and I was able to catch a pose I liked as it recovered. I love backgrounds like this that the island and the bokeh of my lens often provide. Ron
Shrikes, Pellets and Photographer’s Frustrations
For about three years now one of my photography goals has been to get a series of quality shots showing a Loggerhead Shrike regurgitating a pellet. My requirements were that the images must be sharp with good detail and light, there must be no significant distractions or clutter to interfere with the behavior, there should be light in the eye (a catch light) and the last shot must show the pellet after it has left the birds mouth. This post is a progress report of sorts on how I’ve fared with the goal. I’ll include some lessons I’ve learned and mistakes I’ve made so I hope you’ll bear with me through a few less than ideal images which help to illustrate some of those lessons. 1/1250, f/8, ISO 640, 500 f/4, 1.4 tc This was my first image of a shrike ejecting a pellet (3/3/10). I didn’t anticipate it happening and wasn’t even sure what was going on until I processed the image. I got two almost identical shots that showed the pellet in the mouth and missed the pellet as it was ejected (I think I remember my buffer filling up just about then). I was also too far away for good image quality – this is a large crop. 1/3200, f/6.3, ISO 500, 500 f/4, 1.4 tc On the next opportunity (8/5/11) I was frustrated by obstructing branches and a poor light angle. While this young bird was ejecting the pellet it was facing mostly toward me which put its face and the pellet in shadow. Then the juvenile did something completely unexpected…
Just A Shot That I Like… #18 – Fighting Ring-necked Pheasants
In this neck of the woods Ring-necked Pheasants start feeling frisky about this time of year. Territories are being established, hormones flowing and feathers flying. When fighting, these birds flutter up against each other breast to breast, bite each other’s wattles and sometimes make high leaps toward each other using claws, bills and spurs. It can be quite dramatic. Just as the sun came over the mountains I pulled into a gravel hunter’s parking lot at the refuge and noticed these two birds going at it. I assumed they wouldn’t let me get close enough for quality photos but they were so intent on their battle that they mostly ignored me and I was able to get just close enough. 1/640, f/9, ISO 500, 500 f/4, 1.4 tc With the low light I was fighting for both shutter speed and depth of field and was pleasantly surprised to get both birds sharp at these settings. I’m always very happy to get behavioral shots like this, busy background or not. Ron
Birds, Spiders, Brine Flies and Mercury Contamination on Antelope Island
Last Sunday I found this Northern Shrike on Antelope Island enthusiastically singing away as if spring were already in full bloom. Their predatory habits and interesting behaviors make them a favorite species for me but when I got home that day I read an article in the Salt Lake Tribune that made me wonder just how healthy their populations near the Great Salt Lake really are. North end of Antelope Island, 2/5/12 The reason for my concern is a bit complex but I’ll summarize: For over 100 years smelting operations have been responsible for high levels of elemental mercury in the Great Salt Lake and its sediments. Microorganisms in the lake convert the mercury to methyl mercury which is the toxic form of the element that can be absorbed by tissues of living things. Brine fly larvae living in the lake then absorb the methyl mercury and when they hatch the adult flies are consumed by spiders living in the vegetation around the lake. Finally, those spiders are eaten by the many bird species living and nesting along the shoreline. But very little is known about the movement of mercury compounds through Great Salt Lake ecosystems, including the possible effects of toxic methyl mercury on birds so Westminster College’s Great Salt Lake Institute was recently awarded a $250,000 grant from the W.M. Keck Foundation to study its possible effects. Antelope Island causeway, 8/29/11 The number and total biomass of brine flies in late summer around the lake literally boggles the mind but this shot should give you some idea. It was taken in late August of…
American Kestrels In Snow, Frost And Fog
Photographing American Kestrels near the Great Salt Lake during the coldest parts of winter is a two-edged sword. On the one hand the frigid temperatures in December and January make the kestrels “stickier” – much less likely to fly off before you can get close enough for quality photos. But there’s a down side too. Moisture from the lake often forms fog or at least makes the air so incredibly laden with moisture that good lighting often becomes an issue. I’ll still take the shot under some of those conditions though – a close-up with the bird large enough to very nearly fill the frame is still usually much more desirable than a well-lit bird so small in the frame that little detail can be seen. 2000, f/7.1, ISO 400, 500 f/4, 1.4 tc In this image the background is snow and there had been a blizzard the day before which had stacked snow up on one side of the perch. This was one of the first times I’d ever been close enough to a kestrel to get a frame-filling image and I well remember having a case of “buck fever” while photographing him at such close range. Also a bit unusual was the fact that I was actually looking slightly down at him – something that doesn’t happen often with kestrels. 1600, f/7.1, ISO 500, 500 f/4, 1.4 tc This shot illustrates well what you get when the atmosphere is so laden with moisture when it’s very cold – fog, low but even light, some reduction in detail and sometimes…
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…
A Tragedy For A Coyote On Antelope Island
I’ve always thought that nature photographers are some of the luckiest folks on the planet because we get to spend so much time in the natural world that we love and we see some of the most exhilirating sights and wonderous events that nature has to offer. But occasionally there’s a dark side. Yesterday was a difficult day in the field for me on Antelope Island. Be forewarned that the photos are of documentary quality only and that at least one of them may be difficult for some to view. When we spotted this coyote hunting in the grass for voles it was successful almost immediately and quickly swallowed its lunch. A few seconds later I noticed that it looked like it had caught another vole because I thought I could see the vole hanging out the left side of it’s mouth – the grasses were thick and it was difficult to tell. Then we spotted another coyote about a quarter mile behind this one and within a few seconds this animal also caught sight of the second coyote. When it did so there was an instantantaneous reaction – it put its ears down, its tail between its legs and started running through the grass like a bat out of hell to get away from the second coyote. I fired off a few shots as it ran but certainly didn’t get anything to be proud of. It wasn’t until I got home and processed the running shots that I knew something was terribly wrong. This…
Odd Behavior In A Young Male Northern Harrier
It’s likely that I’m more interested in bird behaviors than some of my readers – if so I hope you’ll bear with me through this post. Even though the light was terrible for photography much of the time, witnessing this odd behavior was a treat for me. As most folks who try to photograph harriers know, they’re generally an elusive quarry and difficult to get close to. Occasionally you may get a close fly-by if you’re lucky but yesterday I had an experience with a harrier that I had never seen before and I’ve spent a lot of time around harriers. Mia and I first found the bird (a young male just transitioning to adult plumage) perched close to the road and as we attempted to get close for some shots it lifted off, just as we expected. I assumed it was long gone as usually happens with these birds but that’s not how it turned out. 1/1000, f/5.6, ISO 500, 500 f/4, 1.4 tc As we were preparing to drive further down the road we noticed the harrier coming back and it landed quite close to us again. Very unusual, so we decided to hang around and see how the cards played out. 1/1000, f/5.6, ISO 500, 500 f/4, 1.4 tc The harrier began to call. Sometimes it sounded like the typical harrier call that I’ve heard so many times in the past but occasionally this bird sounded different – Mia thought it sounded almost like a parrot. 1/1000, f/5.6, ISO 500, 500 f/4, 1.4 tc It stayed on the same…
Just A Shot That I Like… #16 – Black-billed Magpie In Flight
Black-billed Magpies aren’t appreciated by everyone. Their raucous behavior and scavenging habits put some folks off but I’m quite fond of them for their relatively high intelligence and incredibly interesting behaviors (examples – they conduct ritualistic “funerals” of up to 40 birds around the dead bodies of other magpies and you haven’t lived until you’ve seen one tormenting a cat by repeatedly pulling its tail). That said, they’re very difficult photographic subjects. Their black plumage soaks in the light while the bright white feathers reflect nearly all of it so getting exposure and detail in the overall bird is incredibly challenging. I probably delete a higher percentage of images I take of magpies than I do of any other species I regularly photograph which makes getting an image I like especially rewarding . I enjoy meeting the challenge… 1/1250, f/8, ISO 500, 500 f/4 When the light’s at the right angle you can sometimes get impressive iridescence in the blacks which also helps to bring out some of the detail there. This bird had just taken off from the sagebrush that its nest is deeply buried in. And it was even considerate enough to give me a pleasing head turn and eye contact as it did so. I’ve photographed this bird and its mate at their nesting site for three years now (and yes I’m very careful not to disturb them). Can’t wait for early spring to try it again. Ron
Northern Harrier Hunting a Vole
Over the last five years I’ve spent an inordinate amount of time photographing, watching and studying hunting Northern Harriers. When they pounce on their prey the action is usually so far away (or buried in the vegetation) that I don’t get a good look at what’s actually happening. But all that changed with this adult female who was so intent on capturing a vole buried deep in the matted, dried vegetation that she virtually ignored me. What fun to watch! Unlike most other hawks, harriers very often use auditory cues (sound) to locate prey. In fact they have a facial “ruff” or disc much like owls do and its purpose is the same – to funnel sounds to the ears. The feathers that form the disc can be raised in response to noise, essentially enlarging the disc and improving hearing. 1/1000, f/8, ISO 500, 500 f/4, 1.4 tc Harriers often hunt along predictable “pathways” and this one had made several passes by me earlier. However this time she attempted to pounced on something right in front of me – almost certainly it was a vole since they are very nearly the exclusive diet of wintering harriers. 1/1000, f/8, ISO 500, 500 f/4, 1.4 tc She missed the vole but from her demeanor she could obviously hear it under the mat of vegetation and she became quite agitated in her attempts to get at it. 1/1600, f/8, ISO 500, 500 f/4, 1.4 tc She repeatedly rose into the air a couple of feet and pounced back down on the same spot with her…
