Just A Shot That I Like… #1

Today I’m starting a new feature on FeatheredPhotography. Typically my posts include multiple images showing a sequence of photos that illustrate bird behaviors, photo techniques, favorite shooting locations and the like. That will not change. But now, in addition I will post a single shot that appeals to me for whatever reason and title the post “Just A Shot That I Like…” and these image posts will be numbered. This is post #1. The photos I choose may be new or from my archives. I’ll mention what I like about the photograph and any significant flaws I think it has. I’ll also include my image techs. My plan is to make one of these posts at least once per week, in addition to my regular posts. 1/2500, f/7.1, ISO 500, 500 f/4, 1.4 tc I found this Song Sparrow early in January 2010 on the coldest day so far that winter. The entire refuge was covered in thick frost – it looked like a magical frosty fairyland all the way to the horizon. The sparrow was puffed up to keep warm and eating ice encased seeds it grabbed from its twiggy perch. I like the frost, the vertical position of the tail, the puffed up squatting pose, the ice crystals falling next to the tail and the whimsical mood of the image. Ron

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…

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…

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…

American Avocet Mating Displays

I’ve been fascinated by the mating displays of American Avocets ever since I first started photographing them almost five years ago. This innate and complex choreography is almost identical in different mated pairs and from year to year. The action happens quickly and is difficult to photograph well but I think I have enough decent images now to make an informative post about it. Not all of the photos are of the highest quality but I think each of them illustrates the behavior well. I’ll present several sequences of different birds that will illustrate most of the important stages of the process. I’m not going to include my techs with these shots -some of them were taken when I first started photographing birds and I made many mistakes in my setting choices. Knowing some of these settings wouldn’t help anyone. Avocets are monogamous and pairs form up in the spring when the female persistently associates with the male until she is eventually tolerated, then accepted as a mate. The female initiates copulation by the posture you see above. It’s called Solicitation Posture and in it she holds her neck extended far out and low. At times it’s so low that much of the head, bill and neck are under water as you’ll see in a later image. Once interested, the male performs Sexual Preening where he stands close to the female and extends his neck so that his bill tip can preen his breast (always on the side closest to her). You’ll see that part of Sexual Preening in a later image but…

The Shot That Broke My Heart

There was a range fire on the north end of Antelope Island yesterday that forced managers to clear out all campers from the campgrounds. So when we arrived early this morning the campgrounds were empty and this young coyote was hunting on the edge of Bridger Bay Campground. Canon 7D, 1/2500, f/6.3, ISO 500, EV +0.33 Normally the coyotes on the island are elusive and difficult to approach but I believe this to be a young one so it didn’t seem overly concerned about us. Besides, he/she obviously already had a quarry in sight deep in the grass and wasn’t about to let us interfere with the hunt. In this image the coyote has just spotted something of interest in the grass some distance in front of “him”. Canon 7D, 1/1600, f/8, ISO 500, EV +0.33 Here the coyote begins to make his stalk. At first he didn’t crouch down so that he could see what ever it was he was after through the grass. Canon 7D, 1/1250, f/8, ISO 500, EV +0.33 But as he got closer (both to the potential prey and to me) he began to crouch down, almost in a cat-like manner. At this point I suspected that something dramatic might happen and tried to prepare myself for “the shot”. The most common prey of coyotes on the island is voles but I was pretty sure it wasn’t a vole because the coyote was too far away from his point of interest when he first spotted it to…

Savannah Sparrows – a Bug’s Worst Enemy

On a recent camping trip to Red Rock Lakes National Wildlife Refuge a rustic old fence near where we camped was the staging area for several hunting Savannah Sparrows. They obviously had nests in the grass nearby and would regularly perch on the fence with prey in their beaks after hunting deep in the grasses. Canon 7D, 1/2500, f/7.1, ISO 640, EV -0.33, 500 f/4, 1.4 tc Boy, did they eat a lot of bugs! Most any kind of Arthropod seemed to be an acceptable part of their diet but this critter was one of their favorites. I believe it to be a dragonfly larvae. Canon 7D, 1/800, f/6.3, ISO 640, EV +0.33, 500 f/4, 1.4 tc When they returned to the fence line they would often have multiple prey in their beaks. I expected them to either immediately consume it or deliver it to the nest but that seldom happened. Instead they would typically hang around on the fence for extended periods of time with the prey still in their beaks – often for 10 minutes or more before eating it or flying off to their nest with it. I can’t explain the behavior but I’m certainly not complaining about it because that little behavioral quirk gave me many opportunities to photograph them with their bills full of interesting tidbits. Canon 7D, 1/2000, f/7.1, ISO 500, EV +0.00, 500 f/4, 1.4 tc Their diet wasn’t limited to insects either, as it wasn’t unusual to see them with spiders. Canon…

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,…

Avocets and Phalaropes in a Hailstorm

Recently I’ve been tardy in posting on this blog because Mia and I just recently returned from one of our favorite camping/photo destinations – four days at Red Rock Lakes National Wildlife Refuge. This trip was a memorable one (as they always are at RRL). Canon 40D, 1/200, f/16, ISO 500 @35mm, ev 0.0 5:30 pm. We were photographing American Avocets and Wilson’s Phalaropes on one of the refuge ponds when we looked behind us to the west and saw this impressive storm heading our way. It was really dumping on the foothills surrounding the valley and we figured things might get interesting so we decided to stay at the pond and see what happened. Good thing we were shooting from my pickup or we’d have been in trouble… Canon 40D, 1/250, f/16, ISO 500 @17mm, ev +0.33 5:52 pm. The slow-moving storm took a while to get to us but when it did it was impressive. It began to rain very hard. It was so intense that neither of us could keep water off of our lenses – in spite of the 7″ long hood on the end of my 500mm lens. I love my new Ford F-150 pickup but the engineers did a poor job on the roof rain channels and water simply poured in off the roof whenever a window was down. As you can see in my side mirror, Mia (who shoots from the back seat) has taken a temporary respite from the downpour and has her lens pulled in and her window…

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…

White Pelican Stretching Pouch in Flight.

American White Pelicans are known to do some pretty strange things with their pouch – one of them is pouch stretching (I’ve been unable to find an official term for the behavior). A four year old image – I no longer have the original file so can’t access exif data They pull their head back and force their very flexible pouch down over their neck and upper chest in a process that looks, well.. bizarre. I don’t think this behavior is particularly unusual as I’ve seen and photographed it several times. According to Birds of North America Online the function of this display is “uncertain”. Canon 7D, 1/5000, f/6.3, ISO 500 However, these birds are also fully capable of pulling the bottom of their pouch up above the level of the lower mandibles without having to pull the pouch down over their neck. I don’t fully understand how they’re able to do this since the pouch itself is non-muscular. Internet research on the subject has been unproductive. I assume there must be some form of bony or cartilaginous rod that extends from the throat area down the middle of the bottom of the pouch about half way to the tip of the bill. With muscular control of the base of that extension in the throat area they would be able to raise the bottom of the pouch above “horizontal”. I’ve seen them do it twice – the first time without a camera while the bird was perched. But the second time, a couple of weeks ago, it was done in flight which…

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…
