The raven call and snowshoe scream originally came from a naturalist site and are quite good. We called in a buddy's first wolf by playing the raven call 2x and the wolf walked out of the trees. I usually start with a raven call. Not sure where the raven and wing came from originally, but works well, especially if you have a raven decoy or 2 out. The jackrabbit distress and raven call will really pull in the birds - after I have done the snowshoe call a couple of times, I will play it. And as we know, where ever there are ravens squawking, a canine will likely pop out to see what the fuss is about.
Hope the moose call works - it is a large file and I haven't used it moose hunting, but it should work. Edit - use the bottom one - its the wav file converted to MP3 format
Thanks Remyltr for putting them on here. Enjoy!
