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…

White-crowned Sparrow Bathing in a Lilac Bush

 I have a serious case of unrequited spring fever.  It’s been a long and dreary winter and it’s not over yet so when I stumbled across these images from last spring a few days ago I decided they were worthy of a post.   Canon 7D, 1.4 tc,  tripod, 1/2500, f/8, ISO 640 It was just after a spring rain in May last year when the sun came out and I noticed this male White-crowned Sparrow fluttering around in my neighbor’s lilac bush so I quickly grabbed my gear and started firing away.      Canon 7D, 1.4 tc,  tripod, 1/3200, f/8, ISO 640 The sparrow seemed so ecstatic over his bath that he let me get close and pretty much ignored me.      Canon 7D, 1.4 tc,  tripod, 1/2500, f/8, ISO 640 The leaves and especially the flowers were loaded with water and the sparrow was taking full advantage of the situation.      Canon 7D, 1.4 tc,  tripod, 1/2000, f/8, ISO 640 And the ecstasy continues.  I guess there’s just something special about bathing in lilac water…      Canon 7D, 1.4 tc,  tripod, 1/2000, f/8, ISO 640      Canon 7D, 1.4 tc,  tripod, 1/2000, f/8, ISO 640      Canon 7D, 1.4 tc,  tripod, 1/2500, f/8, ISO 640     Canon 7D, 1.4 tc,  tripod, 1/2500, f/8, ISO 640 Some of these photos are far from perfect – the light was harsh, the bird was side-lit, I often didn’t get a catch light in the eye and the contrast was high, especially…

Chukars of Antelope Island

 The Chukar, also known as the Chukar Partridge, is a species first introduced into North America from India in 1893.  Since then they have flourished, particularly in the Great Basin of the American west where the largely feed on the seeds and leaves of cheat grass.  Antelope Island in the Great Salt Lake provides perfect habitat for them and they abound there.    Chukar calling In the springtime there are times when the hillsides sound like the island has been overrun by domestic chickens from the calling of the Chukars.      Preening on a rock perch Chukars are very prone to perch on rocks – especially in the spring.  While there they call to other birds and preen.  Sentinel birds of a flock also prefer elevated perches while on lookout, which of course is ideal for the bird photographer.      Parent with chicks And here’s one of the reasons there’s so many Chukars on Antelope Island – the breed prodigiously.  Clutch size can be up to 21 eggs!     Chukar covey on boulder In late summer and fall Chukars often congregate in large groups.  These coveys tend to consist of adults and their offspring but several family groups may mix together.      Preparing to jump off the rock Like some other upland game birds, Chukars are often reluctant to fly.  They will typically jump down from their perch and scurry through the vegetation to hide.  They are very fast runners and easily outrun a human on foot.     Rock hopping  I’m often tempted to call these birds “rockhoppers” because of their tendency…

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…

Horned Larks Blowin’ in the Wind

 I have particularly fond memories of Horned Larks from growing up on our northwestern Montana family farm near Cut Bank, Montana.  The fallow barley fields and adjacent short grass prairies abounded with them.  But since I began photographing birds I’ve had very few opportunities with them here in Utah – until last week when had a grand time with multiple cooperative larks in the foothills of the Stansbury Mountains.   And yes, the wind was blowing briskly – a perfect situation to remind me of those Montana larks!    Singing in the wind The  wind seemed to inspire the males to sing as they all seemed to be singing up a storm on this day, despite the early February date.      Blown off the perch While it may look like this male is taking flight, in reality it was being blown off the perch by a sudden gust of wind.  If it had been taking off, both wings would be extended.       Wind- disheveled  feathers  In this photo, the wind updraft from the rock perch blew a perfect semicircle of his upper chest feathers into his black neck ring, making him look pretty silly.      Very obvious “horns” This photo shows the “horns” (occipital feather tufts) that are characteristic of the species.  The horns are found on both sexes but they are much less obvious in the female and rarely erected.  This frontal view of the head shows the horns most distinctly when they are raised.     Horns laying almost flat At times the horns are laid flat against the…

Bald Eagle Eating a Fish in Mid-air

I’ve often seen Bald Eagles carrying fish but never one actually consuming the meal while flying.  Until yesterday, when I got some photos of the behavior.  Thanks to Mia for calling my attention to it or I may have missed the whole thing.   Eating carp in flight At first I wondered if this eagle was only killing the carp with a lethal bite as I have seen other raptors do in-flight, but then I remembered that it was already dead when it was picked up by the eagle.  These fish were killed by refuge personnel (they use rotenone) in order to prevent damage to the wetlands done by these invasive fish.      Falling fish scales  The four photos in this sequence are in the order that they happened.  Here you can see scales and debris falling from the carp as the eagles very sharp bill does its damage.     Part of the head, including gill flap (operculum) being torn off  I suspect that the reason this eagle chose to consume at least part of its meal in flight has to do with competition.  There weren’t many fish available and lots of hungry gulls and eagles to squabble over them.  If an eagle tried to eat a fish on the ice (the ponds were mostly frozen) other birds would usually challenge them for the meal.  Even gulls were at times very aggressive toward the eagles.  On several occasions I observed gulls biting the tails of the eagles while both were in flight.  Perhaps this eagle figured it had…

Handedness in Short-eared Owls

Last summer Mia and I spent four days photographing a family of Short-eared Owls in Red Rock Lakes National Wildlife Refuge.  There were two baby owls in a nest under a sagebrush guarded over constantly by the female while the male hunted and brought in food.   That food in every instance that we saw was a vole (mouse-like rodent).  Many of the photos I took were of the male in flight, returning to the area of the nest with a vole in his talons. Male with vole It wasn’t until I returned home and began processing the images that I began to notice that the male always seemed to carry the vole in its left foot.  This piqued my curiosity about something I’d never considered – do some birds show “handedness” – the preference of using one limb as opposed to the other?  Could this male owl, or perhaps all Short-eared Owls, be left-“handed”?   Once again, carrying the vole in the left foot So I decided to do an inventory of my images of these birds to see what would turn up.  After culling my photos of these owls from this trip I had 271 photos to go through.  Most of those were flight shots of the male and in more than half of them he was carrying a vole.  My goal was to try to determine how many “sorties” he made with a vole that I had photographed (I often got multiple shots of the male with the same vole in the same sortie) and determine what percentage of the time he…

The Bald Eagle and the Fish Hook

  Last week while looking for Golden Eagles to photograph in the Promontory area at the north end of the Great Salt Lake we came across a group of adult and juvenile Bald Eagles feeding on a sheep carcass.  The light angle was bad for photography but we couldn’t resist taking a few shots anyway.    Bald Eagle with fish hook in bill We were quite close to one adult and when it flew off I instinctively fired off a few shots, despite the poor light.  When I got home and looked carefully at those images I could clearly see this gold fish hook embedded in the base of the eagle’s bill.  This bird was apparently feeding normally and I suspect that the hook will not cause it significant problems while it’s in Utah for the winter feeding on carrion.  However I am concerned that, because of the position of the hook in front of the eyes, the hook will interfere with effective forward vision for fishing after it heads north in March.  I hope it falls out or rusts off before that although I’m not sure if “gold” fish hooks rust at all. An internet search shows that fish hooks are an ongoing problem for both Bald Eagles and Ospreys.  Ron

Bald Eagle Serendipity

  This is another blog post that will be more about the experience of the photographer than about the quality of the images. My good friend Mia and I spent two days this week looking for eagles – both Bald Eagles and Golden Eagles.  We found several of each species but it was a frustrating experience – driving large distances (over 500 miles) and then having bad light, bad luck, bad timing and lots of fog.   Then, an unexpected surprise!   Bald Eagle waiting for us to get home Immediately after getting home I noticed several neighbors down the street looking up in the direction of the large elm tree in my side yard.   I ignored them at first but they persisted in staring so I followed their gaze and couldn’t believe what I saw toward the top of the tree – an adult Bald Eagle!  I live in suburban Salt Lake City and have never seen an eagle in my neighborhood in almost 25 years.   Of course, both Mia and I got out our photo gear and spent the next hour or so photographing the bird.  It was challenging to get good images because of the steep angle and the fact that the eagle was buried in the tree with branches in front and all around.  There were a few angles where we could get an almost unobstructed look at the bird but even then the background is very busy and there are shadows on the eagle.      Wing stretch The eagle was very relaxed in our presence, even…

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…

Bathing Cinnamon Teal/Green-winged Teal hybrid

Though bathing is a common activity for waterfowl it can make for some interesting photographs.  I found this bird at Bear River Migratory Bird Refuge at the end of May last year.    Cinnamon Teal x Green-winged Teal Hybrid male While I was processing some of the images I noticed the unusual crescent-shaped marking running through the eye to the back of the head that is typical of the Green-winged Teal.  I asked several very knowledgeable birders about this bird and they think this is a CT/GWT hybrid, which apparently is quite unusual.       Red eye looking at you through a layer of water While bathing he would repeatedly dunk his head and shoulders under water  and then lift them up, which would roll water over its back and wings.  An interesting process to watch and photograph at such close range.   Here he’s looking at me through a layer of water over his head and eye as he brings his head out of the water.       Forcing water over the back   Here’s the water on the back.        Washing the back feathers Then he would shake vigorously which would wash the back and upper wing feathers and send water droplets flying.       Rearranging the wing feathers After so much vigorous activity the feathers, particularly those in the wing, needed rearranging to put them in their proper places.       Preening after the bath  Then came the preening.  Lots of it.  Here he is grooming individual breast/lower neck feathers.       After the bath And here…

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…

The Northern Shrike and the Good Samaritan

This blog post will be more about the experience I describe than about the shrike images. The Northern Shrike has been a nemesis bird for me for a long time.  I have many good images of its southern cousin the Loggerhead Shrike but the northern is an uncommon winter visitor to the northern US  and I’ve seldom seen one and never been close enough to the species for good, detailed images – until this week.  And I very nearly didn’t get the shots.     Northern Shrike This winter there has been a single (as far as I can tell) Northern Shrike wintering at the Great Salt Lake wetlands where I often shoot but I’ve never been able to get close enough to it for a quality shot.   Two days ago I was finally able to approach the bird but it wouldn’t have happened without the kind actions of a good Samaritan. As I was driving down the dirt road I could see the shrike flitting from perch to perch in front of me.  Several times I almost got close enough but then it would spook again.  Finally, just as I got close and trained my big lens on the shrike, wouldn’t you know it – a car came up behind me on the narrow road.  If it had passed it surely would have spooked the bird.  But it didn’t.  The driver could see my lens pointed out the window at the bird and simply stopped on the road, turned his engine off and waited respectfully for over 5 minutes as I photographed the shrike before it…

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…

Short-eared Owl in the Fog

My friend Mia and I had such a great time in June with the Short-eared Owls at Red Rock Lakes National Wildlife Refuge in Montana that we decided to return in September.  Getting close to them was more difficult this time because they weren’t nesting and feeding young.  However, one morning we got lucky.    A cooperative Short-eared Owl  When we awoke we were socked in with heavy fog.  As it slowly began to clear we went looking for birds and found this owl perched in the middle of the road.  As we approached, it flew a short distance to this post and then allowed us to get very close.  We’re sure this is the same female that we had photographed in June on the same territory.       Short-eared Owl female looking for voles She was very accepting of our presence and within a few minutes was looking for voles below her post perch.  We were right at the edge of the fog and as it would swirl around us, alternately getting thicker and then clearing a bit, we knew that some of our images would show the effect of the fog more than others.  The soft feathers of owls don’t give up their fine detail to photographers easily, even in the best of conditions.  But we simply couldn’t pass up this opportunity with this beautiful female and we still got some shots we like very much.      Short-eared Owl checking us out Occasionally her attention would be diverted from the potential prey in the…
