They sound similar but the howls are much louder. >;-)

I often used to get them going after dark. I used to have a small trailer (caravan) parked about 25km from the nearest hunting camp. Just about as far as you could get away from other humans. I'd wind them up with a challenge call and get them to come in close and then whip snowballs at them. They seemed to enjoy the game.

Unfortunately, the first night I brought my recent bride for the initial fall trip, I thought it would be nice to surprise her with observing nature up close in like fashion even though they was no snow. I tried to explain to her that they had to get passed a 225# Good Ol' Boy with a shotgun to get to her. The next morn, we had to pack up and go home.

Odd thing. When I didn't hook the trailer up to the truck she was perplexed. I said it was to remain for when she next wanted to come up and ushered her into the truck. She said she would not be returning and I replied, "Yeah, that's right." The hour and half drive home was silent and not pleasant. When we arrived home, she was again perplexed as to why I didn't get out of the truck. The drive back when I dropped her off was great fun. So were the next 5 days... after I got home, not so much.
