Does Anyone Know What’s Wrong With The Eye Of This Northern Harrier?

It’s very cold here in northern Utah (8 degrees F. as I type) and there’s lots of snow on the ground – ideal conditions for photographing hunting Northern Harriers.  And yesterday morning everything was covered with a thick layer of hoar-frost which turned the marshes into a frosty fairyland.   I was able to get lots of shots of this particular bird and in the field I didn’t even notice that there was anything unusual about it.  Most of the images were flight shots and there just isn’t time pay attention to detail when you’re concentrating so hard on keeping the bird in the frame and in focus.     But when I got home and started reviewing my images I was taken aback.  Something’s definitely going on with the right eye of this bird.  At first I thought it might be just the closed nictitating membrane but I have dozens of shots of this bird and the eye is the same in all of them.  It’s definitely not a normal membrane, if it’s the membrane at all.     A better look at the right eye.     This is probably the sharpest, most detailed image I was able to get of the bird.     An extreme crop of the previous image to show the best detail I could manage.  To my untrained eye it looks like there may be some kind of fungal growth in and around the eye that may have discolored the eye ring and nictitating membrane and closed the membrane permanently, but that’s only a guess….

A Couple Of Intereresting Coyote Hunting Techniques

New Year’s morning on Antelope Island was a cloudy, low-light affair.  It turned mostly sunny as we left for home in late morning and on the causeway we passed flocks of birders on their way to the island for their first day of birding in the New Year.  I couldn’t help but notice the irony – us photographers who needed good light didn’t get any and the birders who don’t, did… But despite the low light I was able to photograph two coyote hunting techniques that I thought were interesting.      1/800, f/8, ISO 500,  100-400 @ 150 mm, natural light This coyote was on the edge of a large hill overlooking the frozen shoreline of the Great Salt Lake far below.  I was very close to the animal but it was so intent on scanning the marshy area below for prey that it simply ignored me.  At one point it stood on its hind legs with its front legs on a large, snow-covered boulder to give it an even more elevated view of the hunting grounds down below.  I hoped that it would look back at me but it never did, though I think this pose, with just enough of the muzzle in view to show the direction the coyote was looking, well illustrates the hunting behavior. I was pleasantly surprised with one element of this photo.  I was much too close to this coyote to use my 500mm lens so I had grabbed my other 7D with the 100-400 attached and backed the zoom down to 150mm. …

Lickety-split Chukar

We haven’t seen many Chukars recently but yesterday we found a small covey feeding at the base of several rabbitbrush on the north end of Antelope Island.   1/3200, f/6.3, ISO 500, 500 f/4, 1.4 tc, natural light Most of them were pretty skittish but the sentry bird was standing watch on top of a snow-covered boulder as the rest of the birds slowly wandered away.  The sentry posed for us for several minutes.      1/3200, f/6.3, ISO 500, 500 f/4, 1.4 tc, natural light  It called out to the rest of the flock twice.      1/2500, f/6.3, ISO 500, 500 f/4, 1.4 tc, natural light  Chukars are often reluctant to fly and prefer to scurry on the ground to safety.   In an instant the bird accelerated up the rock…         1/2500, f/6.3, ISO 500, 500 f/4, 1.4 tc, natural light  and down the other side.  It was really moving.       1/3200, f/6.3, ISO 500, 500 f/4, 1.4 tc, natural light In this last decent shot I got in the series, the bird appears to be sledding on top of the snow as much as it is running through it. I really enjoy photographing Chukars in the snow this time of year.  For much of the fall and early winter these birds are pretty scruffy looking but now their plumage appears bright and fresh again.

Yet Another Escaped Falconry Bird – This Time A Female American Kestrel

Yesterday morning I spotted this female American Kestrel perched on a far-off rock to the west on Antelope Island.  She was much too far away for decent photographs (as is obvious from the mediocre quality of these first five photos) but when I see raptors at most any distance it’s my practice to “scope them out” through my lens so I can ID them and look for anything unusual or interesting.   I took a couple of shots for documentary purposes but at first I didn’t notice anything noteworthy about her except for the keratin flaking off of her beak.     But then she scratched her face with her foot.  Jesses!  Those damned jesses again.   In this shot you can see anklets above both feet and the jess on the left leg.     She perched and preened on the rock for quite a while and a few minutes later she scratched with her other foot which provided a good look at the jess on the right ankle.     I’m including this shot for a look at her right side, in the unlikely event that some local falconer may recognize her.     I hung around for a long time in the hopes of catching her at take-off for a better look at both jesses and anklets.  As luck would have it, when it happened they were both in shade and I lost focus on the bird but the photo still provides a decent look at the jesses.   I’m deeply troubled by this event and I’ll provide a little background as…

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…

Road-killed Barn Owls

Talk about coincidence! Last night, as I was working up some images of Barn Owls for a blog post on the species, I received the following UBIRD email (used here by permission) from my good friend, enthusiastic birder and budding bird photographer, Shyloh Robinson.  Shyloh lives very close to Farmington Bay Waterfowl Management Area (FBWMA) and this time of year he’s almost always at the refuge in the evenings looking for birds – particularly owls.   “:(   when a grown man uses an emoticon,  you KNOW he’s serious! Each night this week, I’ve visited my home at FBWMA to look at the owls. I went a bit early tonight to make sure I saw some hawks too. They were posted up in the usual spots. I drove straight to the 4way to wait for any short-eared. (That’s the good spot for them.) Sadly, I saw no owls… Until I left and was on Glovers Lane.  Another Barn Owl was dead in the road, and being collected. I got a lump in my throat. I’m quickly learning why moving vehicles are a Barn Owl’s worst enemy. These alba’s have meant a lot to me lately and I’m saddened to see them ghosted. Now what? Shyloh”   Knowing Shyloh as well as I do, I knew he was devastated.  He simply adores “his” owls – an emotion that I share because I’ve spent many, many hours at FBWMA looking for, and photographing, those Barn Owls.  They are a special species, in so many ways. Shyloh’s UBIRD post inspired me to change the focus of my Barn…

Swainson’s Hawk – Contrasting Top And Bottom Views In Flight

This bird was one of the early migrants into Utah in the first week of April this year.  Swainson’s Hawks winter in South America, which means they funnel through narrow Central America as they migrate each way.  To give you an idea of how many birds that involves, 845,000 of them have been counted as they passed over Veracruz, Mexico in a single autumn.  Incredible!    1/2500, f/6.3, ISO 500, 500 f/4, natural light, not baited, set up or called in I found this bird in a remote area of Box Elder County, hunting from power poles.  One of the reasons I like this image is because it’s fairly unusual for me to get a raptor in full flight (instead of just after taking off, note the position of the feet) when it’s not soaring or gliding with its wings in a horizontal position. I’m always interested when I can get images that contrast the ventral and dorsal colors and plumage patterns of the same species in flight.  Swainson’s Hawks are quite dark dorsally.       1/2500, f/6.3, ISO 500, 500 f/4, natural light, not baited, set up or called in But when you can get good light in the ventral view, the contrast is striking.   Even though these two images were taken 34 minutes apart, I’m relatively certain that it’s the same bird in both shots. This hawk was coming to land on a power pole and even though the flight position screams for a perch in front of the bird, I took the liberty of cloning out the ugly pole…

Banking Barn Owl

I have just a single image for this Friday night post. This morning was my first frosty cold morning at Farmington Bay this season and it reminded me of all the very cold mornings I spent with Barn Owls out there a few years ago – an opportunity I haven’t had with the species since.  Hopefully, it’ll happen again some year soon.   1/2500, f/8, ISO 400, 500 f/4, 1.4 tc, natural light, not baited, set up or called in This owl was making a banking turn in front of me so I was able to get a good look at the topside of the bird from my ground level position – something that very few of my Barn Owl flight shots show.  I was slightly further away from the bird than I prefer to be but I still thought the detail held up quite well. In order to anchor the bird in the frame and show habitat, I  cropped this one to include as much of the frosty Phragmites at bottom as possible, Ron

A Northern Harrier Kind Of Morning

Normally I avoid doing back to back posts on the same species but I went out shooting immediately after I published that last post and surprisingly it turned out to be a heckuva harrier morning.  I’ve mentioned  before that I usually have my best luck with harriers in the middle of winter, but yesterday I found two cooperative birds.    1/1600, f/6.3, ISO 500, 500 f/4, 1.4 tc, natural light, not baited, set up or called in This beauty was hunkered down for a break from hunting and let me get surprisingly close.  It was early morning, the light was warm, and the bird posed for me for a long time.  I chose to post this almost direct look from the hawk for a reason – because out of all those images, this one shows the unique harrier facial disc best. A facial disc is a concave arrangement of feathers on the face of some birds (most notably owls) that forms a circular parabaloid that collects sound waves and redirects them toward the ears.  In harriers the disc is less prominent than in owls, but larger in relative size because it extends to the neck, so it is commonly referred to as a facial ruff, rather than a disc.   The large ear openings of harriers are buried in the feathers of the head and can’t be seen.  The angle of the disc or ruff feathers can be adjusted to alter the focal length of the sound waves they’re collecting, which allows the bird to “focus” at different distances – a…

The Challenges Of Photographing Falcons On Antelope Island

There are three species of Falcons that reside on Antelope Island through much of the year – the American Kestrel, Prairie Falcon and Peregrine Falcon.  A fourth, the Merlin, is mostly a winter resident.  For many of us there’s something almost mystical about falcons and most bird photographers I know ache to get quality shots of them.  But doing so isn’t easy anywhere and Antelope Island is no exception. In my experience there are three reasons why falcons on the island are so difficult to photograph well: The falcons are there but, with the exception of the kestrel, they’re difficult to find.  For most of the year Peregrines and Prairies hang out in the remotest parts of the island that are inaccessible to us due to park rules and difficulties of negotiating such steep terrain.  However, all three species hunt the causeway during winter so that’s the best chance for the photographer. Generally you just can’t get close to them.  Kestrels are notorious for that trait, probably because they’re so common that lots of folks try with them.  But common certainly doesn’t mean approachable.  It’s not unusual to see a Peregrine perched far out on the mud flats but there’s no way to get close and if you tried they’d fly off.   Prairie Falcons can often be spotted high up on the rocks around the central part of the island but they’re invariably much too far away and seldom perch near the road. Peregrines and Prairies are much easier to approach in very low light, especially just before sunup.  But low light makes for crappy images. I’ve…

American Avocet In Flight

American Avocets have always been a very difficult flight shot for me so I only have a couple of them in my files.  I think one of the factors that makes them so challenging in the air is their tendency for erratic flight.   1/3200, f/7.1, ISO 500, 500 f/4, 1.4 tc This was a grab shot taken at Glover Pond in Farmington, Utah.  I like the slightly open bill and the position of the wings. This is a species that I too often ignore, whether the bird is in flight or wading.  There’s just so many of them around here for much of the year that my tendency is to bypass them for more elusive subjects. Another bad habit of mine… Ron

Red-tailed Hawk Lift-off

A month ago tomorrow this juvenile Red-tailed Hawk was hunting from the dark Farmington Canyon Complex rocks of Antelope Island.   It would use this elevated perch, and others like it, to scan the grasses below for prey.    1/3200, f/6.3, ISO 500, 500 f/4, 1.4 tc, natural light, not baited, set up or called in I could usually tell from its behavior when it had spotted something and was about to take off after it.  I always hope for a take-off toward me and angled obliquely to my position instead of “dead-on head-on”.  The worst direction is away from me of course and I’ll settle for a fully lateral direction.      1/3200, f/6.3, ISO 500, 500 f/4, 1.4 tc, natural light, not baited, set up or called in Here the bird chose the slightly less than ideal lateral direction.  A head turn toward me would have improved the shot but for some reason this hawk was more intent on the prey than it was in pleasing the photographer.  But I really liked the dynamic body position at take-off.      1/3200, f/6.3, ISO 500, 500 f/4, 1.4 tc, natural light, not baited, set up or called in  Some folks prefer the wings-up position over wings-down but I like them both.      1/3200, f/6.3, ISO 500, 500 f/4, 1.4 tc, natural light, not baited, set up or called in I thought I’d make this final image a vertical composition to show better detail on the hawk, given the flight posture.  The last three shots are sequential images in the…

The Dusky Grouse And The Good Samaritan

Remembering to call this species the “Dusky Grouse” is going to be a challenge for me.  For years they’ve been called Blue Grouse, with two recognized sub-species – Dusky Grouse and Sooty Grouse.  But based on recent mitochondrial DNA studies the two sub-species of Blue Grouse are now recognized as separate species.  Apparently the common name “Blue Grouse” will no longer be used.   1/2500, f/7.1, ISO 640, 500 f/4, 1.4 tc, natural light  I came across this male a couple of days ago while high in the Wasatch Mountains on Francis Peak along Skyline Drive.  I was driving up a steep, narrow road and just as I stopped to photograph the bird a hunter in a pickup came down the road right in front of us.  If he had continued forward the bird would have spooked but when he spotted it and noticed our long lenses pointed at the grouse he very considerately stopped for several minutes so that we could get our shots.  When we had our images I motioned for him to continue, which he did and yes – the bird flew off.   I talked to him for a minute or so and thanked him for his kind deed. In the past I’ve taken the occasional pot shot at hunters on this blog.  But the considerate act of this sportsman reminds me once again to avoid stereotypes – that the unethical, inconsiderate and/or unsportsmanlike behavior of a few renegade hunters should not reflect on the entire group – just as similar behaviors of relatively small numbers of nature photographers should…

Anticipating The Return Of Rough-legged Hawks

Rough-legged Hawks are a true arctic species, spending about 7 months of the year on their breeding grounds in the arctic or sub-arctic tundra or taiga of Alaska or Canada.  Then they migrate south and winter in most of the lower 48 states, with the exception of the SE region and parts of California and Arizona. I love it when they’re here as I find them to be exceedingly handsome birds and I really enjoy photographing them.  And yes, I’m already looking forward to their return.  Every time I’m in their favorite haunts I can’t help looking for them on some of their preferred perches, even this time of year.  So, feeling a little nostalgic for them on a Saturday night, I thought I’d do a post on the species.    1/2000, f/6.3, ISO 500, 500 f/4, 1.4 tc, natural light, not baited, set up or called in Normally I’m not terribly fond of the Tintic Quartzite rocks on Antelope Island as perches because they’re so bright that they tend to blow out the whites but as you can see by the shadows the sun was still very low when this shot was taken so I got pretty good detail on most of the perch.  And besides, I like the rounded, weathered look of this particular boulder.  I do wish the out of focus sunflower heads in the foreground weren’t there but for me they’re not an image killer.     1/2000, f/7.1, ISO 500, 500 f/4, 1.4 tc, natural light, not baited, set up or called in  This is one of…

Escaped Falconry Bird – Peregrine Falcon

Early this morning, just as the sun was coming up over the Wasatch Mountains, we came across this adult Peregrine Falcon, with prey,  along the causeway to Antelope Island State Park.  It is apparently another escaped falconry bird as it had obvious falconry anklets above its feet, though the actual jesses had been removed.   1/500, f/5.6, ISO 640, 500 f/4, 1.4 tc This first image was taken where we first found it – along the edge of the causeway and next to the Great Salt Lake shoreline.  A few seconds after this shot was taken the bird took off.      1/800, f/5.6, ISO 640, 500 f/4, 1.4 tc  But seven minutes later, as we proceeded along the causeway, we found the bird perched on this highway post.      1/1000, f/5.6, ISO 640, 500 f/4, 1.4 tc This shot was taken as the falcon took off from the post.  You’ll notice that the leather falconry anklets, sans jesses, are apparent in each of the above three images.      1/2000, f/5.6, ISO 640, 500 f/4, 1.4 tc And the last time we saw the bird it had landed far away on the large boulders lining the east side of the Antelope Island Marina. We’ve reported this sighting to the Utah Division of Natural Resources and they’ve told us that they will follow up on it. I’ve always admired the sport of falconry on several levels.  Falconers generally have a deep devotion and personal attachment to their birds that I respect and they and their organizations have done a lot for raptor conservation…
