Northern Harrier Defending Its Meal

Long ago I posted some images of Northern Harriers fighting over this Mallard but I have other shots of the fracas that I’ve never posted so I thought I’d share some of them today.    1/1250, f/8, ISO 400, 500 f/4, 1.4 tc For the moment this bird has sole control over the duck but it knows the situation to be tenuous at best.  The wings-out pose and fierce look are fair warning to the other harriers in the vicinity (and there are lots of them) that any attempt to share in the feast will be met with resistance.      1/1250, f/8, ISO 400, 500 f/4, 1.4 tc These birds have been starving because of a brutally cold and snowy winter so this harrier begins a frenzy of feeding in an attempt to swallow as much food as possible before other birds move in.      1/1250, f/8, ISO 400, 500 f/4, 1.4 tc  And it doesn’t take long before all hell breaks loose.  At this point I often wasn’t getting enough depth of field for multiple birds so decided to risk f/10 and a slower shutter speed for the rest of the session.      1/800, f/10, ISO 400, 500 f/4, 1.4 tc  I was lacking in both shutter speed and depth of field for this shot and I’m not happy with the shadow on the face but liked the talons on the back.     1/800, f/10, ISO 400, 500 f/4, 1.4 tc  For a few moments both birds tolerated each other on the duck but that didn’t last long…    …

Fighting Curlews And This Photographer’s Rookie Mistake

Occasionally I’ll make a post that illustrates a mistake I’ve made as a photographer in the hope that it will help me to learn from my error and possibly even enlighten some of my viewers who may be bird photographers.  Well, last week I made a doozy of a mistake! I had been photographing a pair of Long-billed Curlews on Antelope Island and as per usual for me I was using my 500 f/4 with attached 1.4 tc, which when combined with the crop factor of my Canon 7D gives me an effective focal length of 1120mm.   Suddenly a second male unexpectedly flew in to challenge the original male and immediately all hell broke loose.  The action was incredibly quick with wings, legs, long bills and tails flailing in every direction and it turns out that I was simply too close to the birds with my lens and tc combination to prevent clipping body parts in most of my images of the fight.  I remember thinking I should take off the tc but I was afraid that by the time I had done so the action would be over.  That was a mistake – the altercation lasted for several minutes and I had plenty of time to switch. I decided to post some of the series anyway because the tightness on the birds gives an intimate look at some of the details of the squabble but I’ll be the first to admit that I’d trade those details in a heartbeat for having not clipped and cut off body parts.   There were no preliminaries.  The battle began immediately after…

Fighting Chukars

Obviously I’m not posting this shot for its image quality – it’s distinctly lacking in same.  But what an experience we had with these Chukars this morning. We could see them fighting as we approached because they would occasionally jump up above the thick grasses while clawing and biting at each other in the air.   I was amazed both by how vicious these fights were and by the incredible speed of these plump, roly-poly birds.    1/2500, f/5.6, ISO 500, 500 f/4, 1.4 tc We watched several of them fighting for perhaps 5 minutes but very few of my shots turned out because of the fast and furious action in low light and especially because my focus kept locking onto the foreground grasses. But this image should give you a flavor for what it was like and for what my latest photographic goal is – to find some fighting Chukars in better light and out in the open.  I’m gonna work on it!

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.

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…

Just A Shot That I Like… #12, American Avocet Ballet

Occasionally an image still appeals to me despite significant imperfections.  In this shot the cluttered background is not ideal nor are the specular highlights on the leg of the male’s reflection but I quite like the positions of both birds, their reflections and the good separation between the avocets and the reflections.       1/1250, f/10, ISO 400, 500 f/4, 1.4 tc Fighting avocets are very difficult to photograph because typically several male combatants are separated from each other by some distance and you never know which bird is going to go after another one next and when the action begins it is blindingly fast.  There’s also the problem of getting enough shutter speed and depth of field for multiple birds in action.  Shooting these birds fighting is nearly always a “poke and hope” situation. Setting the scene:  I had been photographing four males fighting over a single female (sexes easily identifiable because the female has a shorter and more strongly recurved bill than does the male) when this male lifted off and attacked two other males just out of frame to the right.   I just happened to catch the male in a good position over the female with reflections I liked.  One of the things that made this shot work is that I had enough light to use f/10 for sufficient depth of field and still get a fast enough (just barely) shutter speed to get both birds relatively sharp.  Ron

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,…

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…

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…

The Coyotes and the Plucky Pronghorn

 Yesterday Mia and I were witness to quite the little drama on a trip to Antelope Island to photograph birds.  It all started when we noticed the frantic calling of a Long-billed Curlew which flew over us several times in obvious distress.    Canon 7D, 1/2500, f/6.3, ISO 640, 500 f/4, 1.4 tc At  first we didn’t know what was causing all the ruckus but soon Mia spotted this coyote.  A couple of minutes later we noticed a second coyote nearby.  We suspect that the curlew had a nest in the vicinity and it was disturbed by the foraging coyotes.  Soon both coyotes disappeared into a ravine but we hung around hoping for more flight shots of the curlew.     Canon 7D, 1/1600, f/7.1, ISO 640, 500 f/4, 1.4 tc Then, almost a quarter-mile away, we spotted the coyotes again but this time a doe Pronghorn (at least I think it’s a female and not a young male) had entered the scene.  There was obviously going to be a confrontation and at first I assumed that the coyotes would be the aggressors but I was quickly proven wrong.      Canon 7D, 1/1600, f/7.1, ISO 640, 500 f/4, 1.4 tc This doe had pluck!  After a few seconds of staring each other down the pronghorn charged the coyote on the right.     Canon 7D, 1/1600, f/7.1, ISO 640, 500 f/4, 1.4 tc That coyote beat a hasty retreat but the teamwork the coyotes showed was impressive.  They always stayed a short distance apart and whenever the doe would…

Willet Wars

Earlier this week Mia and I witnessed an incredible display of avian aggression on Antelope Island.  I’ve often seen and photographed battling birds but I’ve never before seen such a long-lasting and vicious fight as this one between two Willets.  It lasted for over 20 minutes and I took 413 photos of the action but don’t expect high quality images in this post as the conditions were far from ideal.  We had contrasty sidelight, lots of obstructingvegetation between us and the birds and constantly changing lighting conditions as clouds moved in and out and the birds moved from place to place as the battle raged.  But as I’ve stated before on this blog I’ll often post images of interesting behaviors even if they are less than perfect in image quality.  And to me this behavior was certainly interesting.    Canon 7D, 500 f/4, 1.4 tc, 1/1600,  f/5.6, ISO 500 The Willets were already fighting as we approached them in my pickup and they mostly ignored us after pausing for a  few seconds when we first drove up.       Canon 7D, 500 f/4, 1.4 tc, 1/1250,  f/5.6, ISO 500 In this and the following image the bird on the right had its bill tightly clamped on the upper mandible of the other bird.     Canon 7D, 500 f/4, 1.4 tc, 1/1250,  f/5.6, ISO 500 The bird on the left was desperately trying to break the grip of its tormentor but it took some struggling before it finally succeeded.       Canon 7D, 500 f/4, 1.4 tc, 1/1250,  f/5.6, ISO…

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 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…

Rough-legged Hawk – Defensive Posture

Most birds are defensive of their territories and space and raptors are certainly no exception.  Rough-legged Hawks and Northern Harriers both prey heavily on voles (mice-like rodents) so when a new bird of prey comes in to the established hunting territory of another there are often conflicts, with the established bird attempting to drive off the interloper to avoid competition for food resources.    Rough-legged Hawk As I was photographing this Rough-legged hawk sitting peacefully in a tree I noted a definite change in its demeanor so I looked around and spotted a Northern Harrier speeding toward the hawk from my right.  I anticipated that the harrier would “buzz” the roughie and since I was much too close to get both birds in the frame when it happened I decided to concentrate on the reaction of the hawk as the interaction occurred.  I never did get the harrier in the frame in any of the shots.   In the image above, the roughie hasn’t yet seen the harrier coming in (nor have I).     The incoming Northern Harrier has been spotted When I noticed this posture change in the roughie I knew something was up, so I looked in the direction the bird was focused on and saw the harrier coming in fast.       Beginning to react Here the hawk is beginning to react to the swift and aggressive approach of the harrier by beginning to fluff up.       Defensive posture This shot was taken when the harrier, traveling very fast, was closest to the hawk – roughly three…

Pied-billed Grebe Feeding Behaviors

Pied-billed Grebes are fascinating little birds with a chip on their shoulders.  They are pugnacious, full of personality and quite small.  They don’t seem to get a lot of attention from bird photographers, possibly because of their generally drab colors and because they’re so common.  I really enjoy watching and photographing their behaviors. I’ve stated here before that “behavior” is a major focus of this blog and if I have images of interesting behaviors that are less than perfect technically I will still post them if they illustrate the behavior well.  There are several in that category in this post.    Grebe with young carp Carp are the primary food for these birds in many of the ponds I frequent.  Even young fish can make a huge mouthful for these very small grebes.       Swallowing a carp I’ve seen it take several minutes for a grebe to finally work one of these huge (for them) fish down their throats.  And I’ve yet to see one give up on the meal because it’s too big.     A slippery meal Fish are slimy and slippery and sometimes get away from the grebe temporarily, though they always seem to be recaptured.      A potential thief in the background  These birds are very social so there’s nearly always other grebes close by when one catches a meal and some of them will invariably try to steal the prize from its rightful owner.  This can make for some very interesting but challenging encounters for the photographer because the action is usually so…
