Strange Encounter with a Northern Harrier and a Junco
For me, life just doesn’t get much better than when I’m watching interesting or unusual bird behaviors up close. I was photographing this male Northern Harrier out my pickup window while it was perched on the clump of snow-bent vegetation you see in the image below when I heard a soft scratching sound coming from the front of my truck. I quickly glanced to my right and noticed that a Dark-eyed Junco had landed square in the middle of the hood of the truck. I thought that was unusual of course but I was more interested in the harrier so I quickly turned back to watching him through my viewfinder and it immediately became apparent that the harrier was now fixated on that junco. 1/3200, f/8, ISO 400, 500 f/4, 1.4 tc I’ve spent hundreds of hours watching and photographing harriers and it’s virtually unheard of for one to take off in my direction when I’m this close to the bird. Usually the direction of take off is away from me or if I’m lucky it might be either to my left or right. But this one had apparently decided that it wanted junco for lunch and when it launched it immediately turned slightly and headed straight toward the junco on my truck hood. 1/3200, f/8, ISO 400, 500 f/4, 1.4 tc If you look carefully at the harriers eyes in all four shots you’ll notice that he isn’t really focused on me – instead he’s looking slightly to my right, directly at the junco on the hood of the…
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…
Angry Barn Swallow
As I approached the parking lot at Bear River Migratory Bird Refuge just before taking the loop road there were myriads of swallows flying around as per usual in spring and early summer. I noticed this Barn Swallow on a post and decided to take a few shots. It let me approach very closely and I didn’t know why at first but it soon became very apparent that this bird was in distress. If you look closely at the image above you’ll notice that there is “something” connecting the tips of a tail feather and one of the primary wing feathers that prevented this bird from flying and as a result it was a very unhappy and frustrated bird! I photographed this swallow for over 10 minutes as it struggled to solve its incomprehensible problem. It would alternately attempt to break the connection by raising and extending its wings and… trying to reach the problem area with its beak, which it just couldn’t quite do. At times its apparent anger and frustration (anthropomorphic of me, I know) became quite evident as it would momentarily cease struggling and just sit there and call out pitifully. But eventually the connection between the feathers broke and the bird flew off instantly – so fast that I missed the shot. I still don’t know for sure what substance caused this problem. It has been suggested by others that it could have been spider silk. I’ve also wondered about the possibility of sticky tree…
American Kestrel, Preening and Stretching
This slightly wet and bedraggled (but still handsome) male kestrel was quite wary of me as I approached him on his favorite perch. 1/1250, f/5.6, ISO 500, EV +0.67 American Kestrels are notoriously difficult to get close to and several times he nearly flew off as I slowly worked myself within good shooting distance. But it had been a cold morning and these birds are more “sticky” in the chill so he allowed me a relatively close approach. 1/1000, f/7.1, ISO 640, EV +0.33 Soon after he became comfortable in my presence the warming sun came out (as you can tell by the difference in background in the first two images) and he began to preen. I got many interesting images of him working on his tail feathers but this one shows the eye best. For protection of their eyes they typically close them as they run a feather through their beak. 1/1000, f/8, ISO 640, EV +0.33 And then he began a long, slow stretch – first by fanning his tail… 1/1000, f/8, ISO 640, EV +0.33 and then stretching out his left wing downward. As you can see, they often stretch all three “limbs” at the same time – tail, wing and leg. 1/1000, f/8, ISO 640, EV +0.33 When it was over he fluffed up his feathers and held this position, with one foot up, for quite a while to enjoy the warmth of the sun. I have many photos of perched kestrels but I don’t often get…
Burrowing Owls of Antelope Island
I simply adore watching and photographing Burrowing Owls. They show more personality and cute little quirks than any other avian species I’ve photographed – especially the juveniles. There are usually three problems with shooting these birds though – finding them in the first place, getting close enough to them for high quality photographs without disturbing their normal activities or making them nervous and catching them out in the open or on an elevated perch so that the vegetation that usually surrounds their burrows doesn’t obscure the birds. Two summers ago a family of these owls had their burrow right along the road on the Antelope Island causeway. They were obviously very accepting of all the traffic so getting close without disturbing them was no problem – I’d just pull up on the road edge close to their burrow and stay in my pickup to photograph them. I photographed them for almost two weeks and I’ve kept a ridiculous number of those images- just can’t make myself delete many of them. The family consisted of both parents and four juveniles. I spent most of my time photographing the juvies – they’re just so vivacious, spunky and full of life that they make wonderful subjects. The problem at this burrow site was two-fold – lots of obscuring vegetation and then when they did perch up higher it was usually on some unattractive pieces of broken concrete adjacent to the burrow. 1/1250, f/9, ISO 500, 500 f/4, 1.4 tc Occasionally one of the juveniles would be perched on this rock when we…
The Trouble With Harems
Mia and I spent most of this week on a camping/photography trip to Flaming Gorge, Utah and we had some wonderful photographic opportunities with pronghorns. We camped on an isolated peninsula and it happened that a buck pronghorn was using the topography of the peninsula to help him keep control of his very large harem of females. The herd consisted of the lone buck and many females – both adults and juveniles. The male was in full rut and frantic to keep his does together and prevent several other males from running off with them. Does have varying mating strategies. Some does, called “sampling” females, will visit several males during the breeding season if allowed to do so. Others, referred to as “inciting females”, behave as sampling females until they come into estrus when they move off from the males which incites fights and aggressive competition between the males. These females always immediately mate with the winning male. Some females employ a third strategy where they join a single male and remain with him throughout estrus – these does are called “quiet” females. Canon 7D, 1/800, f/5.6, ISO 640, 500 f/4, 1.4 tc This poor buck was trying to control at least 28 females and was struggling mightily to do so. One evening we were at the bottom of a string of small hills just as the sun was setting (thus the warm, golden light in these photos). The buck and his females were strung out on the crest of several of the hills and one of the does was giving him a hard time by…
Critters Among the Sunflowers of Antelope Island
Antelope Island is ablaze with color this fall, provided by the common sunflower Helianthus annus. The sunflower display is really quite spectacular this year – the most prolific I’ve ever seen it. I suspect it’s because of the very wet spring we’ve had. The sunflowers can provide a very pleasing setting for wildlife photography, whether the flowers are in focus along with your subject or out of focus to show off some pleasing and unusual color in the background bokeh. Canon 40D @ 72mm, 1/800, f/6.3, ISO 320, EV +0.33 It’s unusual for me to get so close to a pronghorn that I don’t have to use a telephoto lens but these bucks are in rut right now and they’re so intent on herding their harem of females that they’re not nearly so wary of people and vehicles. So I quickly pulled out my old 40D and shot this handsome fella at only 72mm while he was right next to my pickup and staring intently at his ladies close by. This allowed me to keep many of the sunflowers relatively sharp and gave a different “feel” to the image than I usually get with my big glass. Canon 7D, 1/2500, f/5.6, ISO 640, EV + 0.33, 500 f/4, 1.4 tc In contrast to the previous image, this Vesper Sparrow was shot with my 500mm and 1.4 teleconverter (1120mm with the crop factor of the 7D) at f/5.6 which gave me very little depth of field – just enough to get the sparrow sharp but the sunflowers in the background…
Brine Fly Feeding Frenzy at the Great Salt Lake
The Great Salt Lake in northern Utah is a vital resource for many of North America’s birds. The lake is 75 miles long, 30 miles wide and has 1680 square miles of surface area and 335 miles of shoreline. Surrounding the lake are 400,000 acres of wetlands. Roughly 5 million birds of 257 species rely on the lake and those wetlands for food, sanctuary, breeding and as a migratory stopover. And one of the primary reasons the lake is such an asset for them is the endemic brine fly, Ephydra hians. Brine flies can be intimidating because of their massive numbers but they are truly innocuous. They are found only within a few feet of the shore, they don’t bite and won’t even land on humans. And they’re a huge nutritional resource for birds. In the photo above, the blurry brown bits in the background are brine flies in flight that have been stirred up by the feeding California Gull. Different bird species have varying feeding methods with these flies – this species often stakes out a few feet of feeding territory on the shoreline and then rushes through the hordes of flies on the sand, stirring them up, and then snaps them out of the air in large numbers. This bird is looking down the shoreline and preparing for its next run on the flies. Most of the flies are resting on the sand until the bird makes its run. As the gull rushes along the shoreline the flies are disturbed into the air and the bird snaps…
Strategies for Photographing Birds at Take-off
Photographing birds at take-off is very different from shooting them in flight, for a variety of reasons. In fact in some ways it’s more difficult. First, I’d best define what for me is a take-off shot. I think it’s a take-off and not a true flight shot when any of the following conditions are met: a.) the bird’s feet are still touching the perch, b.) the feet are still extended down or behind the bird from the effort of pushing off the perch and not tucked up against the body in an aerodynamic position or c.) it’s obvious from the flight posture of the bird or the presence of the just departed perch in the image that it has just taken off. I realize that this is an arbitrary definition and that technically as soon as the bird has left the perch it’s in flight but that’s how I’ll define it for this discussion. Take-off shots have lots of appeal for many, largely because the effort required for lift-off often provides a very dynamic flight posture with the wings, tail and legs/feet in exaggerated positions compared to “simple” flight. Many novice bird photographers are intimidated by the difficulties of flight photography and attempt take-offs instead, in the mistaken assumption that they should be relatively easy. Not so. Following are some strategies and tips for getting good take-off images that have worked for me. I hope they’ll be helpful to some of you. Plan ahead to avoid clipping body parts – particularly the wings: Many novice avian photographers are unpleasantly surprised by the amount of wing extension during take-off and they cut…
A License to Bird
To be perfectly honest I’ve always been slightly disdainful of personalized (vanity) license plates, at least for me. I generally prefer relative anonymity, partly because my natural inclination is to avoid bringing attention to myself (so why am I blogging?…) Not to say that I don’t enjoy reading them on other vehicles while driving and I often have fun with the challenge of trying to figure out what some of them really mean. Since I spend a lot of time photographing birds I occasionally run across “birder plates” at some of the refuges and marshes I frequent. So recently, after the purchase of a new pickup, I decided to break out of my mold and join the crowd. For me, “HARRIER” was almost a foregone conclusion if it was still available, and it was. Many of the better images in my avian collection are of the Northern Harrier, which most folks refer to simply as “harrier”. Whenever I’m forced to choose a favorite avian subject (a choice I don’t like to make) I typically choose this species. They’re magnificent aerial athletes, beautiful, extremely challenging photographic subjects and they carry that “raptor mystique”. Canon 7D, 1/3200, f/7.1, ISO 500, EV -0.33, 500 f/4, 1.4 tc After waiting over 6 weeks to have them delivered (come on Utah, get on the stick!) they finally arrived a few days ago. Today was my first day photographing birds since I got them and I thought it fitting that I was able to get this shot of a juvenile male harrier taking off from a sagebrush out on Antelope…
