A question for a Wolf Biologist regarding dens
I like to get up in the early morning and hike above my house, I bring a spotting scope and binoculars and enjoy the morning looking for wildlife. A few days ago I was sitting up on a steep hillside when I heard a small noise below me. When I looked down there was a wolf about 100 yards away, It circled around the hillside until it caught my wind, looked up hill at me for a moment then retreated down hill. I assumed it was gone. When I got up to leave a couple minutes later I saw it was only down the hill maybe 250 yards, It of course saw me and started barking and doing warning howls.
I have ran into wolves before and they always leave ASAP, But considering it is denning season it has gotten me thinking that maybe I was in too close proximity to a den. Is that behavior that would insinuate a den is nearby? If so did I adversely affect these wolves and will the female likely go through the effort of moving den sites?
