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…

Antelope Island

  Of the eight major islands in the Great Salt Lake, Antelope Island is the largest at 15 miles long and 4.5 miles wide.  Frary Peak reaches an elevation of 6596 feet.  The island has an intriguing history, interesting geology and free roaming herds of bison, bighorn sheep, mule deer and pronghorn, in addition to a variety of smaller mammal species and plentiful birds.  It is one of my very favorite photography locations – especially for birds.  In this blog post I will present an overview of the island and some of its wildlife.  My next post will deal specifically with bird photography on the island.  The north end of Antelope Island at sunrise as seen from the causeway access road There is a 7 mile long causeway road that provides the only access to the island, which is actually a peninsula when the Great Salt Lake water levels are low.  It’s common to see a variety of wildlife along this causeway including coyotes sprinting at the first sight of an early morning vehicle, American Kestrels, Northern Harriers, Burrowing Owls, Common Ravens and a variety of waterfowl and shorebirds where the water comes closer to the causeway.    Approaching the north end of Antelope Island  As you get closer to the island the water comes right up to the causeway’s edge and typically there’s hordes of waterfowl and shorebirds very close to the road.  In the photo above, several shoreline levels of ancient Lake Bonneville can be seen where wave action eroded “benches” in the sides of the…
