Yep, its a lot of fun to actually bring the animals in to you. The first time I called in some coyotes I was using a yellow woodpecker call. I went with a couple of friends out on a near full moon night and we could hear them out there yelping so we started the call and hid. After a few minutes the far away yelping died out and a few minutes later, using a blue lenses spotlight, we could see about 10 of them approaching from all over the place.
Anyways, my friends got excited and ended up scaring them off, but it was fun to get them in regardless. Since then I've found that it's really pretty easy to call them in. They are really curious and will come in to just about any sound that they can hear, though some do work better than others. Try out several different calls and figure out which ones work best in your area and have fun.
