Okie dokie Steve. We can probably run this one a looooong time. The sounds we use are really simple to do for the most part. I'll start it with one of the basic sounds.
Lip squeeks are just that. You pucker up and suck air in between your lips.A kissing sound. Every body has a pair of lips and often this is all you need to call in a predator. This is a soft quiet sound for close work. Liek when you first sit down after slipping into an area you know predators are using to bed down. It mimics mice, a favorite food source.
What I call hand squeeks fall in this category as well. To do this you lick the back of the hand and kiss it. Wiggling the hand around adds volume and character to it.The harder you suck on the hand the louder it is. You can really make it sound like a rat or squirrel in trouble.This one can be heard as far as two hundred yards clearly by all predators.This one can really turn a coyote's crank. Most of the time they will charge this one.
I slipped up on a pair of fox pups earlier this week and had a ball using just these two sounds on them.I got as close as thirty yards and sat still while they were washing for nap time. Started with the lip squeek. It got their attention but didn't get them up. They would look for a while but not come to me. Changed to the hand squeek and one got up and came within thirty feet looking for the rat. I had to freeze and remain motionless . I was wearing just jeans and a black t-shirt standing in a cattle path. After a while of not hearing or seeing the rat the pup went back and laid down. I played with these two like this for thirty minutes or so before telling them hello. For some reason they got a fire under their butts after that
