Charles Zelenka has lived right up against a mountainside in the community of No Name east of Glenwood Springs in Glenwood Canyon, and he’s used to seeing wildlife in his yard.

During the 17 years that he has lived north of Interstate 70, he has had bighorn sheep, bear, moose and other animals swing through his property, he said in an interview Monday, briefly interrupting himself to whisk away a woodpecker attacking the exterior of his house.
