I have a crow call for locating, and I was wondering if after I locate one can I stalk it, or are they too frisky?

They are as you say very frisky, excellent hearing
And vision. Biggest consideration thou is safety
Unless you are positive you are the only one
Hunting the area---this would be very dangerous.

Does the call I make have do be perfect, or will it make them gobble if its a little off? I am going to hunt the spring season, so what kind of attraction call do I need?

You can definitely stalk turkeys! I do it when I need to and got my biggest long beard that way, just stay back and move slowly running when you need to but you must have cover and like my best bird if you end up having to stalk the whole flock for that gobbler you have to watch and keep track of all those turkeys and where they are looking.
As far as calls you don't have to be very good to call a gobbler you just have to call in the right place at the right time, all you need is to know the yelp to bring in a gobbler. Yelping alone will not bring in all turkeys so it's best to learn them all, I use many calls.

Don't worry if your crow call is a little off. Don't worry if its a lot off. Just make it loud and annoying and they'll gobble. Just don't blow it too long or you may drown out the sound of the gobble with your call and never know they are there. Also, be careful stalking. One, if the turkey catches ANY movement, you're done. Two, if you do stalk up on one and someone else happens to be on that bird, you may catch a load of #6s in the face. Stalking turkeys isn't legal in my state, don't know where you're hunting but you should check the regs. A friend of mine almost bought a face full of shot when someone decided to put a stalk on his full strut decoy. He was hit in the face by the bark that was shot off of a nearby tree. Not saying don't do it, just know the laws and be careful! Good Luck!

Someone mentioned locating birds using an air horn... I don't think it takes much to get a shock gobble when they're all wound up.

Check your state's laws, I know that in my state it is illegal to stalk turkey.

Except . . .
A couple years ago I was working my way down a little valley, hit the crow call every so often. I was about 3/4 ways through the valley and hadn't heard a thing. Then, a group of Canadian geese flew down the center of the valley making a racket. A turkey gobbled back behind me where I had just come through. Sometimes, I think, it takes a little more to get a response. Now, what I do when using a locator call is give it a short blow first, then, sometimes, follow it up with a longer call if I don't get a response on the first one.

What I frequently do is try a couple locator calls,like
Crow,owl, Canada goose. If none of them work---
Sometimes they do and sometimes they don't,
Then I'll try a couple hen yelps and wait a bit
In case a Tom is coming in quiet. With all
Calling I start not real loud and then up the
Volume if at first no response.

I've seen several calls. One is the wooden one, one is that clay with a stick I think. What are the different calls used for, and what noises do they make? Can turkeys see orange, or should I not wear it?
