yep.....gota agree....somethings they do......sometimes for whatever reason the switch it up....but i know of some birds that are there daily unless something major happens.....spooked....and ive kinda noticed that when storms move in late in the day they arent there the next day...my theory is that maybe they roost where they are caught in the storm or whatever....i dont know for sure....just seems that way......ive hunted some birds that roost all over the woods....same general area but all around....then other birds roost in the SAME exact tree daily.....all depends......
