I guess there is something to say about having confidence in a sound, and being more likely to use it. I have used the GFP to recall one that came in to a cottontail distress but hung up out of shotgun range and had left once before. Maybe the combination of the two would make a combination to try out on more stands. I wonder how educated foxes can become to a sound? I know there are more hunters than I calling around here, and the GFP has been most hunters #1 for years. I have also noticed that the clearest sounds seem to work alot better, and my GFP has a little background noise to it. I have it in my head that the higher pitched and busier sounds appear to be from smaller critters that the Greys can handle alot easier. I think it is also a confidence builder because the smaller sounds are more likely to be made by something a Grey can easily handle. Also, they may shy away from the sound of a larger critter probably being attacked by something even larger, like a Coyote that a Grey would want to avoid. The reason I think this is because when I hunt around places that have heavy Coyote sign, the Greys seem to be very careful and slow to come to the call, and other areas where I find no Coyote sign they are pretty eager at the right times. I wonder if a sound with the combination of sounds like a young cottontail to create excitement, and that of another Grey Fox or other critter that a Grey isn't afraid of as a confidence builder would make a good call? Again, I don't have anything to prove any of my ideas, just my thoughts on what I have observed, and I'm not a pro at this by far. I have a really hard time accepting the fact that not everything that happens it nature is base on rationality. I always set up my stands to make the appearance as though something typical has happened. Such as: an owl took a swipe at a rabbit and only injured it, the rabbit has made it to a brush pile and the owl landed and is trying to pull the rabbit back out of the brush by a leg. Of course, the only sound I'm playing is the rabbit in distress but I want the fox to think that there is an easy meal to be had if he runs off the original attacker. I don't want the Grey to think he might be coming in on a Coyote doing something similar. I know the GFP works well for some, and if it works for them great. I know I shouldn't care why it works if it brings them in, but thats not in my nature and it may help me figure out why it has never been real good for me. I figure the more I know about how they think and their nature the better I'll be at taking them consistantly.
