“Pursue Ewe” A pair of bighorn sheep rams chase a ewe through sagebrush flats in the North Fork of The Shoshone River Valley. Shoshone National Forest, WY.
What appears to be a larger bighorn ram chasing a smaller one is a bit of an illusion – there is a ewe behind the lead ram and they’re both chasing her. The chase during autumn rut lasted for several minutes at high speed in open country. Imagine my surprise when I edited these shots awhile after returning from the trip and saw two butts on the lead ram. However amusing, these creatures are amzingly athletic, even while running full-tilt through sagebrush. The peak of rut (mating season) for bighorn sheep in Greater Yellowstone is in the first two weeks of December.
