Attack Of The Shoveler

Most Northern Shovelers breed far north of my area (northern Utah) so I rarely get to see their intensely agonistic breeding behaviors but I’ve seen and photographed some of it in mid-June at Red Rock Lakes National Wildlife Refuge in sw Montana. Northern Shovelers are the most territorial of all dabbling ducks and the sexes remain paired longer than any other species.  Both of these factors contribute to their aggressive natures. These three sequential shots don’t have great image quality but I do think they illustrate some interesting behavior.    1/2000, f/7.1, ISO 500, 500 f/4, 1.4 tc I’d been photographing Short-eared Owls from my pickup but was aware of some activity from shovelers in the marshy grasses nearby.  A commotion got my attention just in time to see the male on the right fly in to attack another male on the water.  The second bird saw the attack coming and decided that discretion was the better part of valor and rose from the water in a hasty retreat.  I like the non-plussed look of the retreating bird.       1/2000, f/7.1, ISO 500, 500 f/4, 1.4 tc  In this second image of the series it’s not clear if the open bill of the incoming bird is due to aggressive vocalization or an attempt to bite the other male.      1/2000, f/7.1, ISO 500, 500 f/4, 1.4 tc But in this last image I think it becomes obvious that the  intent was to bite the retreating duck. Bird behaviors fascinate me.  They’re often both interesting and entertaining but many of…

Mean-fighting Coots

American Coots are, without question, the most aquatic, common and widely distributed rail species in North America.  Clumsy and awkward fliers, they require long running take-offs to become airborne but they are skilled swimmers – largely due to their lobately webbed toes. And oh, are they ever ornery! But first, allow me to make a few excuses…  These images of fighting coots were taken several years ago when I was relatively new to photography.  My settings weren’t particularly appropriate so I’m not including them here.   And most of these photos were shot in JPEG rather than RAW, so my processing options were extremely limited when I tried to adjust exposure, so the frustratingly white bill is pretty bright in a few of these images.   This is one of the aggressive postures used by males to challenge other males.  Whenever I see this I know that all hell is about to break loose and I’d better be ready.     In my experience, coots have two primary fighting strategies.  One is for each bird to lie on their backs in the water while propped up by their wings and tails and strike out at each other with their feet and claws.  In this fighting position, their defense is to try to grasp the opposing birds feet.  Here we get a good look at those unusual lobed toes.  If they become locked together they then fight with their bills.     The second fighting strategy uses bills and wings as weapons.  If one bird gains the advantage it often tries to force its opponent underwater.     The losing bird…

Northern Harriers Hunting

It’s getting to be what I call “harrier time” here in northern Utah so I thought I’d do a significant post on the species.  For me, watching these birds hunt is absolutely mesmerizing and I could do it for hours.  And I have – many, many times. But before I get into hunting I’d like to cover some basics on telling the sexes and ages apart.  Sexual dimorphism in harriers is exceptional among birds of prey – telling adult males from adult females is easy because their colors are so dramatically different.  But because juveniles of either sex strongly resemble adult females, that distinction becomes very tricky and causes a lot of confusion.  So, here’s a primer: Adult males – gray above, mostly white below, black wing tips, lemon-yellow eyes Adult females – brown above, buffy with  brown streaks below, lemon-yellow eyes (but in my experience, the eyes of adult females tend to be less bright than those of adult males) Juvenile of both sexes – similar to adult female but darker chocolate-brown above and strongly rufous (reddish) below Juvenile male – pale, greenish-yellow eyes Juvenile female – dark, chocolate-brown eyes   All sexes and ages have the unique facial disc (ruff) characteristic of harriers.   It’s not as prominent as it is in many owls but it can clearly be seen in this image.  Its function is the same as it is in owls – to direct sound to the ears.  Most hawks hunt almost exclusively by sight but because of their excellent hearing, thanks largely to the facial disc, harriers depend at least…

Western Grebes – Aggressive Speed Demons

I’ve spent a lot of time over the years watching and photographing the behaviors of Western Grebes and I’ve been impressed by both their aggressive tendencies toward other birds and by their incredible acceleration and speed in “running” across the water at those same birds.  In my experience that aggression is most often directed toward other grebes in defense of mates, chicks or feeding areas but they are also aggressive toward a variety of other species and are suspected of stabbing them with their bill from under water.  BNA reports Mallards and Red-necked Grebes found dead from stab wounds to the abdomen that were probably administered by Western Grebes. I’ve found photographing them as they dash across the water to be very challenging because of their speed and the unpredictable nature of the behavior – it usually comes with little or no warning and direction is difficult to anticipate.    1/1250, f/6.3, ISO 640, 500 f/4 Though these birds appear slim while sitting on the water, in reality they are fairly chunky and at the end of one of these “runs” their wide body throws up quite a wide wake as they begin to slow down and settle back into the water – much like a speedboat after the engine has been cut.     1/1000, f/6.3, ISO 500, 500 f/4, 1.4 tc  This grebe is early in the acceleration stage with its “bow” still raised high.      1/1000, f/6.3, ISO 500, 500 f/4, 1.4 tc  And then another wake as it begins to settle into the water.      1/1600, f/6.3, ISO 500,…

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…
