A great bear call is a thick blade of grass... makes a scream like a hurt rabbit if you "whine" with it like a baby... "whaaa whaaa whaaaa".... called in a couple like that... calls in the ravens too for some reason... and coyotes lol... you can also make one out of popsicle sticks.... soak two popsicle sticks in water for an hour or so..then give them a slight bend and let dry.. then... get 1 wide elastic band and 2 small elastic bands.... use the wide band around one popsicle stick from end to end.... place the other popsicle stick on top of the one with the wide band around it and use the 2 smaller elastic bands to pinch and hold the ends together.... it then makes the blade of grass cry too only it wont rip on you when you wail on it like grass does.
