If you are hunting public, find a back access or come in for a different angle then most people do. It throws the birds off.
I hunt a lot of popular spots that get hit weekly. The difference between me and the average person is they go in the parking lot, and work the way everyone else does. I come in from the side or the back side on a gravel road of some sort and the birds don’t expect that.
In the later season like this you have to think ahead of the bird.
Birds were jumpy from the start of the season for me however. It just goes to show being quiet is key. Pick who you hunt with.
Opener I hunted with a friend of mine who took his dad who is a big time duck hunter. He for some reason brought his duck call with him. During our pheasant hunt whenever he saw ducks, or heard ducks he would stop, pull out his call and blast on it.
I turned around and walked back to the truck lol.
