A buddy and i have started tryin a new strategy that seems to be working pretty well. We get in the river bottom right next to the river and call down the river. Sound travels pretty well. We start off with fairly low volume trying to call in the closer birds first, then increase the volume picking up the ones further down the river. My question is once we are on full blast calling in the long rangers should we back the volume off once we see them commin in or leave it cranked?
I experimented with this last summer, at first we thought that it worked better to lower the volume as they were coming in. After awhile, I decided that it made no difference.
I also call on river a river bed. I hunt the Sandy River pretty hard, it flows past my house.
Sometimes the volume can make them flare if they are really close. It usually happens when there is silence in the recording and the sound comes in with birds close.
As far as water is concerned, it has the same effect as rock would. It is a great medium for sound reflection. Sound carries really far over water. Have you ever been in a boat 1/4 mile away from someone else and overheard their conversation like you were in the boat with them?
