The weather in Yellowstone over the last week has not been particularly enjoyable, but the wildlife viewing has been exciting. There were at least two bison carcasses in the Hayden Valley that attracted multiple grizzly bears. I felt privileged to watch the cycle of life exhibited at one of these locations.
The bison rut (mating season) occurs in August. Early last week, one unfortunate male took a horn in a bad spot during a sparring match and died just northwest of Grizzly Overlook in the Hayden Valley. As of last Wednesday early in the day, the carcass was yet to be located by grizzlies or wolves. A coyote spent a little time there early in the day, followed by a few ravens here and there. I spent a good part of the afternoon watching and waiting. Late in the afternoon I left the carcass to drive along the river looking for bison that might be crossing. Not too far from the carcass a bear jam developed close to the road, with two dark grizzlies sleeping in the woods. After watching these bears for awhile, one awoke and started moving north (toward the carcass). This shot is the bear as it began moving north
When the bear was no longer visible from the road, I decided to head back up to the carcass in case that was where the grizzly was headed. When I got there, some visitors told me they could see a bear nearby. I climbed the ridge and could see a different grizzly not too far off. It was digging for roots and grubs, apparently still unaware of the nearby meal. The winds then shifted a bit, and began blowing from the carcass toward the bear. It didn’t take long for the grizzly to have his nose in the air sniffing. This shot is when he realized what was close by.
