I have a friend coming down to hunt in the Spring. We've got LOTS of birds, here......but I'm a bit nervous about locating them prior to his arrival. Is the best time to locate them before daylight? If I'm scouting during daylight hours.....am I taking a chance they'll peg me, calling?

Relatively flat land, here....but there are some mildly elevated perches from which to begin.

Any help would be appreciated.
