I recently talked with a WDFW guy that was doing a study on Golden Eagles. He said that whenever an Elk collar stops moving for some time they assume the animal is dead and they send someone to find it. He told me that in many areas they are seeing evidence of Elk having been killed by a cougar jumping on them from above, with quite a bit of tearing and damage on the back of the neck area. He said this typcially indicates a "toothy" or old cougar that is missing quite a few of it's teeth, and is old and not able to hunt like a younger cat. He said they become very opportunistic and will climb trees and ambush an animal as it passes below. I pulled out my maps and he showed me a couple of areas where they had seen quite a bit of this activity. I figure that such a cat may be lured by the sound of an easy meal. I plan to spend a bit of time trying this winter. I'll post my results, good or bad. He indicated that in some areas, the cougar population is up.
