Find the main water source.

Find the big stand of trees near by that have open branches for easy access to fly up & down.

Find feathers and droppings at the base of the current "roost tree".

Get in quietly and set-up +/- 100 yards away.

Bring a cushion and shooting sticks.

Call softly, until you get good.

Decoys help.

Remaining motionless is the best camo.

Most wear gloves and head & face covers.

They hate it when I say it but, call them in close and shoot them in the head - dead bird !

Good luck !!!
