Northern Harrier Vomiting

No great photography today but some interesting behavior. I’ve often seen and photographed various bird species hacking up a pellet but this was my first experience with one vomiting. 1/500, f/7.1, ISO 500, 500 f/4, 1.4 tc When I first got this Northern Harrier in my viewfinder I thought it was acting slightly odd – it seemed lethargic, reluctant to fly and its head was hanging low. Then it suddenly vomited. 1/500, f/7.1, ISO 500, 500 f/4, 1.4 tc The vomitus was thick, mucus-like and stringy and I’m quite sure no pellet was expelled. I had an email discussion about this behavior with a friend (thanks once again Ingrid) and sent her these photos. They were forwarded to the Cascades Raptor Center who said that this behavior is something they’ve not seen before and that it isn’t “normal”. When this bird had finished vomiting it stayed perched (very unusual) as I drove through a gate perhaps 25′ to the right of the bird. I drove down the road to let it recover in peace and when I returned about a half hour later it was gone. Ron

A Wonderful Antelope Island Morning – Including A Long-tailed Duck

It’s been a frustrating photography week for both Mia and I for a variety of reasons but it’s primarily been because the weather and light have seriously sucked – big time!. So when yesterday’s dawn showed promise we headed for the island with high hopes but low expectations because there haven’t been many bird opportunities out there recently. We were in for some pleasant surprises. I’ll present these images in the order they were taken to give a feel for the morning. 1/2500, f/7.1, ISO 500, 500 f/4, 1.4 tc We had barely made it onto the causeway before this Rough-legged hawk began to entertain us. We watched as it ate a vole and then it immediately walked about two feet to its left and picked something else up with its foot. At first I assumed it was another vole, either alive or from a food cache. But in looking at close-ups of some of the photos I’m pretty sure it’s only a rock with old brine fly larvae cases and small twigs frozen to it. Then this hawk did something strange – it transferred the “rock” to its beak and deliberately flung it a good distance – here it’s flying through the air Then the bird walked over, picked up the rock in its left foot and flew off with it. My curiosity is killing me as to just what was going on. Obviously this isn’t a great shot but I was fascinated by the behavior. 1/2000, f/7.1, ISO 500, 500 f/4, 1.4 tc Next this Northern Harrier gave us…

Northern Harrier In Flight

Usually winter has been the best time for me to photograph Northern Harriers but my opportunities with them have been relatively sparse this year. So with the season rapidly coming to an end I was delighted to find this cooperative bird yesterday morning near the Great Salt Lake. 1/2000, f/7.1, ISO 500, 500 f/4 The harrier allowed a close approach while hunting and this time the light was favorable too. Occasionally the bird would look up and provide good eye contact. 1/1600, f/7.1, ISO 500, 500 f/4 I found it difficult to get anything but sky in the background but for this image it dipped down low enough for me to get the lake as a backdrop. 1/2500, f/7.1, ISO 500, 500 f/4 The sun was high enough that the far wing was usually shaded while in the down position but I think there’s still enough light and detail there to make this work. 1/2500, f/7.1, ISO 500, 500 f/4 Here the bird was a little past me but the slight look back I got helped to compensate for that. It’s very possible that this was my last good harrier opportunity until next winter so I’m appreciative of yesterday’s serendipitous encounter. Ron

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…

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…

A Howl of a Surprise

When you’re out in the field you just never know what you might see. Or hear. On an early morning this week I found this Male Northern Harrier on a trail sign. Since the perch was not a natural one I set up to try to get a take-off shot if he should lift off. 1/1600, f/6.3, ISO 500, 500 f/4, 1.4 tc As usual I was shooting from my pickup and in order to get in position for good light I had to park in the middle of the lightly used road. In such cases I always roll down the window on the passenger side so that I can hear any vehicle that might approach so I can get out of their way (it’s very easy to not see an approaching vehicle while concentrating on a bird through the camera’s viewfinder). Having that window down made a big difference to how I reacted to what happened next. 1/1600, f/5.6, ISO 500, 500 f/4, 1.4 tc Suddenly there was a piercing howl that was so loud it sounded like it was coming from inside my truck! Seriously, I almost jumped out of my skin it startled me so much. It was this coyote, hidden in the grasses. It was only about 75′ away from me and with three of the four windows down the clamor was tremendous. Coyotes often howl as loudly as 105 decibels and believe me that’s a very impressive din at this close range – especially when it’s unexpected. At first I could only see the…

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…

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…

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,…

Northern Harrier Male in Flight

Just a single image of a male Northern Harrier in flight but this shot means a lot to me. Canon 7D, 1/6400, f/5.6, ISO 640, EV – 0.o, 500 f/4, 1.4 tc I have many nice harrier images taken during winter around the marshes of the Great Salt Lake but for me this species has been a nemesis bird during spring and summer. Most of our harriers migrate north in early spring and those that stick around become very difficult to approach. For three summers now I’ve been trying mightily to get a decent flight shot of a harrier to no avail. I can’t tell you how many times I’ve done some crazy driving (I’m usually shooting from my truck) trying to intersect the flight path of one of these birds only to have it veer off before it got close. As Mia often says – these birds like to “yank my chains”. Then, about three weeks ago, this male apparently forgot to “yank” and flew relatively close to me. I rattled off a burst and got this one image that I like. My techs for the image weren’t ideal but it still worked out and I’m delighted. I guess it doesn’t take much to satisfy this bird photographer sometimes… This post will be a bit of an experiment. I’ll be out of town for a couple of days so I’m preparing the post now and will test the delayed posting feature of WordPress. Hope it works. Ron

Northern Harrier with Nesting Material

I’ve been photographing Northern Harriers in northern Utah for five years now and until earlier this week I’d only seen this species carrying nesting material once before and wasn’t able to photograph it. Harriers are very common here during winter but most of them head north for the breeding season and those that stay usually build their nests in inaccessible areas of the marsh, so it’s rare for me to see any nesting activities. Canon 7D, 500 f/4, 1.4 tc, 1/2000, f/7.1, ISO 400 Two days ago Mia and I were photographing birds at Bear River Migratory Bird Refuge. We were about to call it a day because it was late in the morning and light was no longer optimal when we spotted this harrier flying at a distance. We figured it would veer off before it got close, as they always seem to do out there, but this one kept coming toward us. We were watching it through our lenses and soon noticed that it had nesting material in its beak. Canon 7D, 500 f/4, 1.4 tc, 1/2000, f/7.1, ISO 400 By chance we happened to be at a place on the dirt road that was within 100′ or so of the nest of this bird. It decided to ignore us and come in to complete its delivery. Canon 7D, 500 f/4, 1.4 tc, 1/2000, f/7.1, ISO 400 The nest is apparently in this bed of last year’s dead Phragmites. The dark spots you see in the last three images of this…

Fish Eating Northern Harriers

As I’ve mentioned before in this blog, the winter of 2008 was a particularly brutal one in northern Utah. During January and February there was much more snow than usual and it was bitterly cold. During most winters our Northern Harriers rely primarily on voles as a food supply but in 2008 with the voles under the deep crusty snow our harriers were desperate for food. Birds of North America Online provides extensive information on the dietary habits of harriers. It lists small to medium-sized mammals (primarily rodents), birds, reptiles and frogs as harrier food sources, stating further that the diet of harriers during winter in their northern range (which includes northern Utah) consists of voles “almost exclusively”. I can find no mention of harriers eating fish, ever! Each year in early February some of our wetlands managers treat some of our ponds with rotenone (a chemical that prevents oxygen from being absorbed across fish gill membranes) in an effort to control the invasive and damaging carp that do so much damage to the emergent vegetation which is so vital for waterfowl. So, in 2008 for a few weeks, our desperate and starving harriers began to eat fish! In the three winters since then I have never seen harriers eating fish even though the dead carp are always plentiful after the rotenone kill. 1/1250, 1/1000, ISO 500 Many of the carp are brought to the shores or ice surface by Bald Eagles which makes them available to the harriers who generally cannot retrieve them from the water. 1/1250, f/8, ISO…

Northern Harrier Struggling to Expel a Pellet

Except for owls, all raptors have a crop for excess food storage. The parts of the prey that are indigestible are formed into a pellet in the gizzard and then regurgitated out of the mouth. These pellets contain hair, feathers, exoskeletons and sometimes (in the case of owls especially) the bones of their prey. I’ve noticed with many raptor species that expelling a pellet can be a difficult process, bordering on traumatic. Such was the case with this juvenile male Northern Harrier. I was watching this bird through my lens but not planning on getting any quality photos because the bird was strongly side-lit. But when he began trying to expel a pellet I couldn’t resist clicking away. Because of the side-lighting and relatively soft focus the images are not of high quality but I thought the behavior was interesting enough for a blog post anyway. All of the photos in this series are posted in the order that they were taken. The beginning of the struggle to expel the pellet Here the harrier is shaking his head from side to side to try to dislodge the pellet But with the effort he begins to lose his balance on the perch And almost falls over backward He begins to recover And then falls forward Begins to recover again Still recovering Recovered, but still with the pellet stuck in his mouth And finally the pellet has been expelled. As luck would have it my buffer had filled up and I missed…

Northern Harriers Battle over a Mallard

Occasionally we have brutally cold winters here in northern Utah. It’s my opinion that unusually cold temperatures when combined with thick crusted snow gives harriers little access to their staple food around here – voles. Survival then becomes tenuous for the harriers and they’re forced to move on to other food sources like small birds, dead carp and waterfowl. When a large meal like a carp or duck is available many harriers often fight over the food item and they do so with ferocity. During less stressful times of the year I often see these birds skirmish but then it almost seems like a playful interlude that they do simply for “fun”. Not so when it’s very cold and food is scarce – then it’s deadly serious and incredibly interesting to observe and photograph. First, a disclaimer. Some of the photos I’ll present here would wither under the scrutiny of critique because of cut off or clipped wings, missing eyes or heads, lack of catch lights and difficult and rapidly changing lighting conditions. My intent here is to show the behavior with the best images I have but some of them do have obvious flaws. The calm before the storm I didn’t see harriers make this Mallard kill but it was still fresh when I came across this bird on the duck. At first I though I’d simply be photographing the harrier calmly enjoying its meal but I was very mistaken. Thinking about challenging the larger bird for the meal It didn’t take long for other birds to challenge her for the Mallard. Some were timid…
