You can use a speck call and make it sound just like the predator calls.
When I was younger, I would sit up on an old windmill water well and crack them.
They like to lick the yellow milk crapp from young calves. If you have a lot of calves
in a field, they will come up and lay along the edge of the field in the late evening,
just before dark and wait for dark to come eat *****.
If you get there before them, you can pop one or two. I have seen them come up
and lay apart from each other outside the fence line. I shot one and the other got
up and went to the one I shot. I popped her next. I just shot them due to the fact
that they will sooner or later kill a weak or single calve hiding in the grass.
Hurricane Rita took care of all of them South of the ICW.
You can also catch them with traps. When you find a dead cow, put some traps
all around the cow in 2 rows. They are suckers for dead animals.
If Rita took them out, they're back by the hundreds around hackberry, fishing flounder cut one morning in last winter we had one come of the levee and swim across the cut, stopped boat traffic dead in the water.
