Back in 2007 and we made one of our numerous trips out to Yellowstone. That year the weather was not very cooperative so we did not have as many good photo opportunities as we usually do when we go to Yellowstone. The bright spot of the trip was the coyote den that we found, along with numerous other photographers, out on Blacktail Plateau. Mating season for coyotes is from January to March. The female goes in heat for less then a week so timing is very important. The gestation period is about 2 month. The pups are born blind and helpless. They will remain this way for about 10 days. They will remain in the den for about 3 to 4 weeks.These pups have emerged and have probably been weened and are eating meat. The coyote pictures that I took that year have been the most popular pictures on my blog with nearly 40,000 hits. If you would like to see the rest of the series click on the link below.
