RE: Tips for roosting birds
Locator calls for sure. Try a crow or owl or coyote or peacock. They may or may not sound off.
If you have more than one spot to try, locating will tell you where they will be in the AM. That's helpful to many hunters because it gives them confidence to stick it out if the birds are quiet in the AM.
I try to hunt all day or most of it anyway, and I'll call from one location off and on for a couple hours. So, I don't really careif I locate them the night before or not. I have a lot of success calling birds in between say 9:30 and noon and even later. A locator call can be useful when moving between spots during the day too.
