Golden Eagle – Some Progress On A Nemesis

Anyone who follows this blog knows that I have a penchant for raptors and over the last 6 years of photographing them I can count on one hand the number of good opportunities I’ve had with Golden Eagles.  I had another chance at one yesterday on Antelope Island.  I almost didn’t spot this bird because it was hunkered down so far in the sagebrush (here it is standing more erect in anticipation of flight).     1/1600, f/7.1, ISO 500, 500 f/4, 1.4 tc I knew that my only chance for a few decent images would be at take-off or just after but the angle of light was a problem – the bird was facing almost directly into the sun.  If it veered to its right I’d get butt shots and probably lose the head behind the wings.  If it turned to its left the face would be in shadow and I’d get no catch light.  What can you do but wait, be ready for lift-off and hope for the best from a less than ideal situation?        1/1250, f/7.1, ISO 500, 500 f/4, 1.4 tc  Thankfully the eagle launched straight ahead which gave me the best light I could hope for under the circumstances.       1/1250, f/7.1, ISO 500, 500 f/4, 1.4 tc   For the first wing-beat I got light on the head and a catch light in two images – then the bird turned slightly toward me and that light was lost.  I got several more sharp shots with dynamic flight poses but the face was completely shaded.  Curses !!! I…

Short-eared Owl Delivering Food To The Nest

In previous posts (here, here and here) about these Short-eared Owls at Red Rock Lakes National Wildlife Refuge I’ve shown and described snippets of the fascinating behaviors I observed when this male would deliver voles to the female and two youngsters at the nest.  But it struck me that I’ve never put the whole process together in sequence so the behaviors could be fully appreciated so that’s what I’ll attempt to do here.   Most of the images will be different from those in the previous posts.     1/1250, f/5.6, ISO 800, 500 f/4, 1.4 tc The male was a tireless and highly skilled hunter and I never saw him with any prey other than voles.  When successful he would always return to the vicinity of the nest and land momentarily on one of two favorite perches – the dark sagebrush at lower right in the above photo or a metal post a few feet from the sagebrush.  Here he’s coming in for a landing on the sagebrush with vole in talons and glances up at me to make sure all is safe.  I really like the intense direct eye contact in the shot.       1/1000, f/5.6, ISO 800, 500 f/4, 1.4 tc  Now he’s focused on the sagebrush in order to make a successful landing.       1/1250, f/5.6, ISO 800, 500 f/4, 1.4 tc This time he stayed perched for less than five seconds and didn’t even pull his wings in against his body – he just kept them out or up while he seemed to contemplate his next…

Birds, Spiders, Brine Flies and Mercury Contamination on Antelope Island

Last Sunday I found this Northern Shrike on Antelope Island enthusiastically singing away as if spring were already in full bloom.  Their predatory habits and interesting behaviors make them a favorite species for me but when I got home that day I read an article in the Salt Lake Tribune that made me wonder just how healthy their populations near the Great Salt Lake really are.    North end of Antelope Island, 2/5/12 The reason for my concern is a bit complex but I’ll summarize:  For over 100 years smelting operations have been responsible for high levels of elemental mercury in the Great Salt Lake and its sediments.  Microorganisms in the lake convert the mercury to methyl mercury which is the toxic form of the element that can be absorbed by tissues of living things.  Brine fly larvae living in the lake then absorb the methyl mercury and when they hatch the adult flies are consumed by spiders living in the vegetation around the lake.  Finally, those spiders are eaten by the many bird species living and nesting along the shoreline.  But very little is known about the movement of mercury compounds through Great Salt Lake ecosystems, including the possible effects of toxic methyl mercury on birds so Westminster College’s Great Salt Lake Institute was recently awarded a $250,000 grant from the W.M. Keck Foundation to study its possible effects.      Antelope Island causeway, 8/29/11 The number and total biomass of brine flies in late summer around the lake literally boggles the mind but this shot should give you some idea.  It was taken in late August of…

Just A Shot That I Like… #17 – Short-eared Owl In Flight With A Vole In Its Beak

This is another image from my time with the Short-eared Owls at Red Rock Lakes National Wildlife Refuge.  This male was kept very busy hunting voles and feeding his mate and youngsters at the nest.   Typically I would see him hunting far off, dive for a vole, and if he was successful he’d occasionally eat the vole himself but most often he would return with it to a favorite perch in the vicinity of the nest – and without exception he would always carry the vole in his talons before he got to the perch (and always his left talon, but I covered that topic in another post).     1/1600, f/5.6, ISO 800, 500 f/4, 1.4 tc However, just before (or just after) he took off from the perch to deliver the meal to his family he would always transfer the vole from his talons to his beak.  I have a theory as to why he did so.  The nest was on the ground at the base of a sagebrush.  Whenever the male landed at the entrance to the nest with the vole the female would rush out and very aggressively grab the vole.  And I DO mean aggressively!  If I’d been him I’d have been afraid to get that close to her with food.  So the male would approach the nest very gingerly with the vole in his beak and drop it in front of him and quickly retreat as she rushed out.  I suspect it was easier for him to avoid a confrontation with her if he could quickly drop…

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…

Kiting Rough-legged Hawk

Kiting is the ability of some birds to maintain a stable position in the air by using air currents rather than by the flapping of wings or hovering.   Last week I had a wonderful opportunity with this young Rough-legged Hawk while it was kiting in the stiff wind rising up from the Antelope Island causeway.  The light was good and the bird was cooperative and let me get close – what more could a bird photographer wish for?      1/1000, f/8, ISO 500, 500 f/4, 1.4 tc It was amazing to see how still in the air this bird could be – often maintaining the same relative position to the ground without significant wing movement for long periods.  I swear that if I had been using a tripod I could have focused on the bird, walked away for 10 seconds or so and then returned and snapped the shutter with the hawk still in the frame and without having had to look through the viewfinder or refocus.   A bit of a stretch perhaps, but not by a lot.       1/2500, f/6.3, ISO 500, 500 f/4, 1.4 tc Much of the time the hawk was hunting – looking down into the grasses for voles.  That head position doesn’t provide the eye contact that is photographically desirable but I wanted to include a shot that illustrated hunting posture.         1/1600, f/6.3, ISO 500, 500 f/4, 1.4 tc The hawk caught several voles while I was photographing it.  In this instance the bird immediately took to the air with the very young vole…      …

Just A Shot That I Like… #10 – Prairie Falcon In Flight, With Duck Kill

This morning was cold and very windy out on Antelope Island and most of the birds seemed to have taken refuge from the freezing gale so as we left the island I figured it would be one of  those relatively rare days when I had been photographically “skunked”.   But as is so often the case, the island had a pleasant last-minute surprise in store for me.     1/1600, f/6.3, ISO 500, 500 f/4, 1.4 tc This Prairie Falcon had apparently killed a duck (which I believe to be a Northern Shoveler) and was trying to defend it from two marauding ravens so the  falcon decided to haul the shoveler off to a more private and secluded dining area.  That turned out to be an unfortunate decision as very soon after this photo was taken a Bald Eagle flew in and forced the falcon to drop the duck.  The eagle flew down to the ice, retrieved the duck and nonchalantly flew off with it. The wing and back of the duck are covered with snow/ice crystals.  The out of focus lighter “blobs” in the lower background are whitecaps on the Great Salt Lake.  This falcon is the same bird I photographed a little over a month ago and posted here.  I know that to be the case because the same wing covert is askew in both birds (though it can’t be seen in this image).  I’ve now been able to photograph this falcon on four different occasions in the last few weeks.  What a treat!

Lazuli Buntings of the San Rafael Swell

For me Lazuli Buntings have long been an elusive subject.  Though they’re common in the western U.S. I rarely see them near my home and when I’ve found  them in my travels they either won’t let me get close or they’re buried in thickets where I can’t get clean shots of them.   All that changed on an early June photo/camping trip to Utah’s remote and visually stunning San Rafael Swell.     1/1600, f/8, ISO 400, 500 f/4, 1.4 tc  I found the males singing on territory and more cooperative than usual since their preferred singing perch was at the top of low shrubs and they were often so involved with their melodious territorial declarations that they sometimes let me approach them quite closely.  This one is perched on greasewood which provided some nice green colors in this arid habitat that they prefer.  I like this good look at the bi-colored bill of the species.       1/1250, f/7.1, ISO 400, 500 f/4, 1.4 tc At times one of these males would give me a clean perch and background for a typical “bird on a stick” image.      1/1250, f/6.3, ISO 400, 500 f/4, 1.4 tc But more often than not the perch would be more cluttered.    Here I’m less than happy with the out of focus twigs in the foreground but I liked the cottonwood “cotton” stuck to the bill.  The unusual background color is from the Entrada Sandstone so common in the area.       1/1250, f/8, ISO 200, 500 f/4, 1.4 tc I’ve seldom seen birds get so…

Just A Shot That I Like… #8 – Prairie Falcon In Warm Light

I’ve tried and failed for a long time to catch a raptor perched on the darker rocks (Farmington Canyon Complex) that are most common on the southern part of Antelope Island.  I think these rocks make much more attractive perches than the almost white and difficult to properly expose Tintic Quartzite boulders on the north portion of the island.   Last week I finally succeeded with this Prairie Falcon.    1/1000, f/7.1, ISO 640, 500 f/4, 1.4 tc As an added bonus the sun was just coming up over the Wasatch Mountains so the golden light added some warmth to the image which I like.  I only got off  a handful of shots but at least the bird turned its head into the light before it  flew off.  Based on bill color I believe it to be a first year bird.  Now if I could only get this close to a Peregrine Falcon in good light… Ron

Just A Shot That I Like… #6 – Short-eared Owl In Flight With Prey

Sometimes conditions are marginal at best for avian photography and that often seems to be the case for me when I’m presented with an otherwise wonderful opportunity.  Then the decision must be made –  go ahead and shoot anyway, knowing it’s likely that I won’t get any keepers or just pack it in and watch and enjoy the birds?      1/640, f/5.6, ISO 800, 500 f/4, 1.4 tc, noise reduction to background   Such was the case with this Short-eared Owl at Montana’s rugged and remote Centennial Valley.  It was an overcast day and there generally wasn’t enough light for photographing birds in flight but this male was regularly delivering voles to his family and would occasionally fly right by me as he did so.  I could have removed my teleconverter to get a little more shutter speed but then the owl would be quite small in the frame so I just decided to fire away and hope for the best.  Even at ISO 800 (the absolute limit for my 7D without getting too much noise) I was often getting shutter speeds of 1/500 or slower at f/5.6 – just not fast enough to get birds in flight sharp. I got lucky with this shot.  As the owl was coming in, the clouds behind me opened up slightly to allow a little more light on the bird and a shutter speed of 1/640 – just enough to get good sharpness on a relatively large and slow flying bird if your focus is well locked on to the subject.  The still shaded Centennial Mountains provided…

Just A Shot That I Like… #5 – Great Horned Owl In Tamarisk

We recently found a Great Horned Owl that likes to hang out in some tamarisk close to the Great Salt Lake.  Usually the owl is deeply buried in the foliage and can’t even be seen unless you know where to look but of course getting clear shots of the bird is impossible in that situation.    1/2000, f/7.1, ISO 500, 500 f/4, 1.4 tc   However on cold early mornings this bird likes to get a little warming sun and has found one spot where it’s open enough that it can soak in some rays and still feel safe and hidden by the enclosing tamarisk.  By careful maneuvering I can get a relatively clear view of the owl from a close vantage point (without disturbing it).   It’s a busy setting for the bird but I like that the spot it has chosen to warm up in is so dense with leaves that they almost seem to wrap protectively around the owl.  We’ve had several opportunities with this bird in exactly the same spot over the last couple of weeks.  At least we thought it was a single bird but then yesterday sharp-eyed Mia noticed (while editing and culling  images) that the plumages don’t match from day-to-day.  There are two owls that use this spot and we have photos of both of them.  A pleasant surprise!  Ron

A Very Cooperative Rough-legged Hawk

In a previous post I mentioned that I had been encouraged by the number of Rough-legged Hawks (roughies) I’ve been seeing this fall.  Well I’m delighted to report that the situation continues to improve.  On virtually every photo expedition over the last few weeks I’ve seen several of them and on two recent trips we’ve made about a dozen sightings of different individuals each time.  However getting good photos of them is a different story altogether.   After a season in the high arctic they’re very unapproachable and even when I have been able to get reasonably close they’re usually perched on an unattractive sign or post and take off away from me.  All that changed a few days ago though when we found one very cooperative bird.  This species has the most different male and female plumages (sexual dimorphism) of all our buteos and I’m quite sure this is a light phase female.     1/1000, f/6.3, ISO 640, 500 f/4, 1.4 tc We first spotted this bird on a low wooden post that resembled a piling and I was pleasantly surprised that it let us approach (in my vehicle) with no signs of nervousness.   It was early on a cold, frosty morning and while looking through the viewfinder I assumed that the material on top of the post was spider silk that had collected dew and then frozen.  But after looking at the photos at home I wasn’t so sure so the next day I walked over to the post to check it out.   Duh – should have known.  It was  frosted bison fur.  This was Antelope Island…

Prairie Falcon – A Nemesis Resolved

Every avian photographer has their “nemesis birds” – a species or two that the gods of photography have foiled any and every attempt at getting quality images of.  For me the Prairie Falcon has been at or near the top of that list.   I particularly love to photograph raptors but locating and then getting close to this falcon in good light has eluded me for five years now.  But two days ago I resolved that dilemma!     1/4000, f/5.6, ISO 640, 1.4 tc We first spotted this bird coming towards us along the Antelope Island causeway just as the sun peeked over the Wasatch.  It soon landed on this stump and in good light but I wasn’t quite as close to the bird as I’d like to have been.  Soon it lifted off and hunted the causeway going west, causing quite a ruckus among the gulls, shorebirds and ducks as it approached them.  It was fairly easy to track the falcon by watching for groups of panicked birds taking to the air.      1/1000, f/5.6, ISO 800, 1.4 tc Next it landed on this interesting rock and I was able to get a little closer.  The background is a little funky with the harsh color transition between water and rocky shoreline passing through the bird but I liked the perch and the good look at the entire bird, including tail.  I suspect that this falcon has learned the fine art of thievery.  Earlier this week we observed a Prairie Falcon along the causeway chase off a Peregrine Falcon from its Ruddy Duck…

Just a Shot That I Like…#3 – Chukar In Snow

The Chukar is a type of partridge that was introduced to Antelope Island many years ago and they thrive there.   They’re originally native to Asia and are a popular game bird, though their range in North America is restricted because they thrive only in areas of low rainfall and humidity.   1/2500, f/8, ISO 400, 500 f/4, 1.4 tc I found this one last winter on a boulder just after a fresh snow fall.  Though the white part of the background may look like clouds it is actually a snowy hillside with blue sky above.  I like the soft colors, coy pose, rocky perch and the snow in the setting with the blue sky up top.  Some may miss seeing the feet but that’s a trade-off I’ll gladly make to catch this handsome bird in the snow.

Rough-legged Hawks Return To Utah

For the last couple of years I’ve had very little luck locating Rough-legged Hawks (roughies) here in northern Utah, which frustrates me because I think they’re among the most handsome and photogenic of all the raptors and I love to photograph them.  These birds breed in the high arctic so they aren’t here at all during the summer.  Most of them winter in the “lower 48” but they are highly nomadic and their numbers in a particular area fluctuate according to the availability of their rodent prey.  This year I’m greatly encouraged because in the last ten days or so I’ve seen many of these striking hawks.     1/1600, f/7.1, ISO 500, 500 f/4, 1.4 tc This one was atop a perch that is photographically challenging – a Tintic Quartzite boulder on the north end of Antelope Island.   These rocks often blow out the whites on the sun side, especially if the bird on them is dark.  I’ve deleted many a shot of a raven on one of these boulders.       1/3200, f/5.6, ISO 800, f/4, 1.4 tc This morning I had a wonderful (though sometimes frustrating) time with the roughies on the island.  The highlight of the morning came when I was trying to sneak up on a kestrel perched in a rabbit brush.  As I did so I noticed a gull flying right toward the kestrel but I quickly ignored it and concentrated on the kestrel.  Then, at the last second, something in my mind said “hey, that was no gull” just as the bird swooped low…
