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…
