one of the easiest calls to learn is a slate and peg style call.
or you could get a push pin call.a box call is another fairly easy call to get the hang of.
if you are going to be hunting with out a blind i would recomend something that is weather resistant.some types of slate and peg and most box calls wont work
when they get wet.however there ae alot of them being made thses days that have a weatherproof surface to them.
i would recomend going to a seminar near by you and just aske the guy running it everything you can think of,from call types to using them properly,to setting up decoys ets.some say decoys dont work,some like them.i use them but it all depends on the circumstances too.
i myself have many many many calls,but i am a fanatic when it comes to turkey hunting.
hell our season doesnt start untill mid april and i start practicing with my mouth calls in January.so i pend about 5 months out of the year with a mouth call in my mouth.
not saying i am real good,but i do try competitive calling.not to win,just for more practice.
you dont have to master any call to call in ground buzzards.
your basic yelp is all you realy need to know,but some light clicking and even light purring will help.
one key thing to remeber is,dont over call.i always listne for what the boss hen is doing and try and mimic that.if shes is yelping hard and loud,then thats what i do.if shes real soft and sublte,then that what i do.if you can get her into a calling contest with you,she will almost always come your way to show you who the boss hen is.
when she does this,most times the rest of the flock will follow along and drag in the toms with them. dont believe anyone when they say turkey hunting is easy because they are dumb.
they have better eyes tha a deer does.some claim they can spot the blink of your eye at 10 yds.their vision is like you standing at the field edge with a pair of 10x binoculars,very sharp creatures,but when they are in breeding season,they can also be a little,well lets just say eager to die
good luck and happy hunting this spring
peace,
