June 11, 2011May 27, 2018Black Bear Black Bear Cub of the Year (“COY”), Yellowstone National Park “Hey Mom, Wait Up!” This is a good time to be in Yellowstone to see bear cubs. While I enjoy photographing all cubs, the spring cubs, also known as cubs of the year, or “COYs,” are the cutest. Spring cubs are tiny. How tiny? I think of them as footballs with legs.
