I am new to turkey hunting. I went with a freind last year, we herd some birds but Ive never got one to close the distance. So heres my question.

1. I hunt 6000 acres in north florida, very little pressure on turkeys, however i havent had one single shock gobble, and during last spring couldnt get anything to talk back. am i just that horrible at calling or is it issue due to bears/cyotes which are both plentiful in the area.

I have bought a few different varieties of calls, mouth, slates, boxes, non of which seem to have effects. There are turkeys in the area, we see plenty of hens when scouting, and even seen gobblers when deer hunting in the fall. theres a healthy mix of hardwood heads, tall pine short pines and a new clearcut about 300 acres. there are food plots which vary from 800 yard lanes to 1-2 arce openings. they are planted in rye in the winter and millet and peas in the late summer.

2. what do the birds like to be in when mating, ive herd they prefer to be in/around the hardwoods when roosting but do they like the tall pines which are relatively open underneath or the short thick stuff?

Turkeys like tall pines, cottonwoods etc. They will generally roost in an area they can see danger coming from or are protected in some way like roosting over a river, swamp etc. They also like to roost in gully's, 3/4 way up a hill so they can see the hill top and have easy fly up down.

Not sure what locater call you are using try a coyote call, that should work for you.
Also in Colorado turkeys are almost never in the fall location in spring, I have seen areas where they are.
I would focus at least 1 mile away from the fall location, get high and at dark am or pm call with the coyote call several times if necessary, if they are there they will answer. Matting will be where ever they are strutting.

Good Luck!
If a turkey hangs up wait till safe then move forward 60 ft. or so then call again get aggressive, there is no sure fire recipe you will feel what you need to do by what he responds to.
