Shrikes, Pellets and Photographer’s Frustrations

For about three years now one of my photography goals has been to get a series of quality shots showing a Loggerhead Shrike regurgitating a pellet.  My requirements were that the images must be sharp with good detail and light, there must be no significant distractions or clutter to interfere with the behavior, there should be light in the eye (a catch light) and the last shot must show the pellet after it has left the birds mouth.   This post is a progress report of sorts on how I’ve fared with the goal.  I’ll include some lessons I’ve learned and mistakes I’ve made so I hope you’ll bear with me through a few less than ideal images which help to illustrate some of those lessons.    1/1250, f/8, ISO 640, 500 f/4, 1.4 tc This was my first image of a shrike ejecting a pellet (3/3/10).  I didn’t anticipate it happening and wasn’t even sure what was going on until I processed the image.  I got two almost identical shots that showed the pellet in the mouth and missed the pellet as it was ejected (I think I remember my buffer filling up just about then).  I was also too far away for good image quality – this is a large crop.           1/3200, f/6.3, ISO 500, 500 f/4, 1.4 tc On the next opportunity (8/5/11) I was frustrated by obstructing branches and a poor light angle.  While this young bird was ejecting the pellet it was facing mostly toward me which put its face and the pellet in shadow.  Then the juvenile did something completely unexpected…

Just A Shot That I Like… #16 – Black-billed Magpie In Flight

Black-billed Magpies aren’t appreciated by everyone.  Their raucous behavior and scavenging habits put some folks off but I’m quite fond of them for their relatively high intelligence and incredibly interesting behaviors (examples – they conduct ritualistic “funerals” of up to 40 birds around the dead bodies of other magpies and you haven’t lived until you’ve seen one tormenting a cat by repeatedly pulling its tail).    That said, they’re very difficult photographic subjects.  Their black plumage soaks in the light while the bright white feathers reflect nearly all of it so getting exposure and detail in the overall bird is incredibly challenging.  I probably delete a higher percentage of images I take of magpies than I do of any other species I regularly photograph which makes getting an image I like especially rewarding .  I enjoy meeting the challenge…         1/1250, f/8, ISO 500, 500 f/4 When the light’s at the right angle you can sometimes get impressive iridescence in the blacks which also helps to bring out some of the detail there.  This bird had just taken off from the sagebrush that its nest is deeply buried in.  And it was even considerate enough to give me a pleasing head turn and eye contact as it did so. I’ve photographed this bird and its mate at their nesting site for three years now (and yes I’m very careful not to disturb them).  Can’t wait for early spring to try it again.  Ron

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…

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…

Loggerhead Shrikes Impaling Prey

  Shrikes have been called “butcher birds” for their habit of impaling their prey (insects, small rodents, reptiles or birds) on thorns, barbed wire or other sharp projections.   They do it for several reasons.  It helps them to tear  the flesh into bite sized pieces, they use it as a method of caching (storing) their food and it helps them to survive eating the toxic lubber grasshopper because the toxins within the insect degrade to harmless substances within a couple of days.   I had never seen or photographed this behavior, or evidence of it,  until this summer when I did both several times.                         In the first  three photos below, this juvenile Loggerhead Shrike is practicing this instinctive behavior but the bird apparently isn’t very skilled at it yet as it had some difficulty impaling the dragonfly on the short thorn just below the insect.  In the first image the bird seems to be trying to decide which of several thorns to use for this grisly task.    Preparing to impale the dragonfly      Impaling the dragonfly on a thorn        The dragonfly has been impaled, though a little off-center.   In this case the bird didn’t wait long to begin eating the prey.  Here it has torn off the head and the front part of the abdomen with one pair of wings attached and is swallowing them.  As you can see, the rest of the insect is still impaled on the thorn.   Soon after this shot was taken the shrike removed the rest of the dragonfly from the thorn, flew with…
