A Loggerhead Shrike, a Spider and Spit
A few days ago Mia and I found this Loggerhead Shrike sitting prettily on a dried sunflower on Antelope Island. The bird was using the sunflower as a hunting perch. 1/1600, f/8, ISO 500 I’ve always been amazed by the incredible eyesight of many bird species. This shrike somehow spotted a spider crawling through the thick grass about 20 feet away from where it was perched and immediately flew down to grab it. 1/1600, f/7.1, ISO 500 It was a relatively small spider and I have no idea how the shrike was able to see it in all the dense grass. Even though the background is busy here I still liked the shot for the interesting look at both the spider and the tongue of the shrike. It’s my presumption from looking at this photo that the saliva of the shrike is viscous and sticky, enabling the prey to stay attached to the tongue during the very fast process of pulling the spider to the back of the throat with the tongue. 1/1600, f/7.1, ISO 500 A heavily cropped, close-up view of the same image provides a clue. You can see that there’s a sheet of saliva stretched between the bottom of the tongue and the floor of the lower mandible and it does appear to be quite viscous. I had no idea that it would be so “juicy” in there. Nothing earth-shattering here, just some avian trivia in a photo that I found interesting (yes, my interests can be…
Early Spring Birds and Craziness on Antelope Island
Typically our first spring camping trip is a shake-down cruise for the trailer to Antelope Island. If anything goes wrong with the trailer (and it sometimes does after sitting all winter) I’ll be relatively close to home. This year we spent the last two days of March on the island. Most of the photos in this post were taken on that trip. 1/2500, f/6.3, ISO 500 There’s been a few Western Meadowlarks on the island for much of the winter but they’ve returned in large numbers now. In all my travels in the west I don’t think I’ve ever seen any other area with such a high concentration of this species. At times their beautiful song resonates all over the hills of the island. Meadowlarks always bring back fond memories for me of growing up on the Montana farm. 1/2500, f/6.3, ISO 500 Loggerhead Shrikes are another very common species, especially on the northern part of the island. They’ve been absent all winter but we’re seeing more of them on each visit now. It was cloudy when this image was taken and I didn’t get a lot of light in the eye but I think there’s just enough. 1/2500, f/7.1, ISO 500 I always look forward to the return of the Long-billed Curlews with great anticipation and they started appearing about 10 days ago. I was happy to get this shot of the male on the right displaying for the female. Male and female curlews are almost identical but they can be differentiated by their…
Common Merganser
This winter I had my first good opportunities with the Common Merganser. A single female in non-breeding plumage spent several weeks at a pond I frequent and even though the lighting was typically marginal while I was there I still got some shots of her that I like. 500mm, 1.4 tc, 1/500, f/7.1, ISO 640 Notice the serrated bill of this fish eating duck – a very effective tool for holding on to their slippery prey. 500mm, 1.4 tc, 1/2500, f/7.1, ISO 500 This duck gave me a variety of interesting poses in the several days I photographed her but much of the time she was too far away for a quality shot. This was one of the exceptions. 500mm, 1.4 tc, 1/400, f/7.1, ISO 640 I had a difficult time getting light in the eye while she was preening. Here’s one image where I succeeded. 500mm, 1.4 tc, 1/1600, f/7.1, ISO 500 I’m convinced that the reason this merganser hung around the pond for as long as it did is because she was an accomplished thief. The pond had a resident population of about a dozen Pied-billed Grebes and those grebes are very good fishermen. I seldom saw the merganser actively fishing but whenever a grebe caught a fish this duck was instantly in pursuit in an effort to steal the fish – which is just what she’s doing in this shot. 500mm, 1.4 tc, 1/1600, f/7.1, ISO 400 I was often amused by the variety of positions the merganser could hold her crest – from slicked back…
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…
Long-tailed Weasel – Efficient Hunter and Cannibal
Long-tailed Weasels are obligate carnivores (eat meat exclusively), preying largely on smaller rodents but also take rabbits, chipmunks and birds – including poultry. They take down prey several times their size and occasionally go on killing sprees triggered by the smell of blood. Long-tailed Weasel, summer molt Their long black tipped tail, slender bodies and darker brown coloration above with creamy white ventral parts are identifying features. The very similar Short-tailed Weasel is smaller and has whiter feet. In this case the prey is another weasel While driving the loop road at Bear River Migratory Bird Refuge this weasel ran in front of us carrying another weasel that it had apparently killed. Weasels are cannibalistic at times and I’m relatively certain that this kill was destined as a meal rather than the kill being made simply out of aggression because the winning weasel was very reluctant to abandon its prize even with us very close. It took a great effort for the weasel to carry its long-bodied kin through the grasses and reeds and it simply would not abandon it. Hopping with it’s prey Here you can get a feel for how difficult it was to drag the long body through all the obstructions so most of the time it would hop forward, one jump at a time, presumably with its burrow as a goal. Long-tailed Weasel, winter molt As winter approaches, northern weasels molt to white (while retaining the black tipped tail) – the advantage of this is obvious. Interestingly, many weasels living in the southern part of their range…
Tree of Death (warning – graphic!)
In late January my friend Mia and I made the drive to the Promontory area north of the Great Salt Lake in a quest for Golden Eagle photos. We did find some eagles but were definitely unprepared for what else we stumbled upon. Second warning – most of these photos are graphic and may be profoundly disturbing to some. If you proceed further in this post, please – no complaints about what you’ve seen. You have been twice forewarned. A misleadingly idyllic scene What we found was the kind of country that I love – wide open spaces, big skies, blissful silence and isolation. The setting reminded me of the area around Cut Bank, Montana where I grew up. Tree of death So what a shock it was to come around a bend in the dirt road by this little reservoir and find such a horrific scene! Someone had apparently shot two Red Foxes, a domestic cat and a Common Raven and deliberately hung them in this tree right next to the road as some sort of a sick trophy display. First Red Fox in tree This Red Fox had been hung by its neck in a fork of branches. Second Red Fox in tree This one was simply draped over a stronger branch, very close to the road and with no obstructing branches between the fox and everyone who was forced to look at it as they came around the curve in the road. Cat impaled on fence post…
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…
