i use a varmint squaller. it moves chipmunks, bluejays, causes squirrels to change location, calls in some crows sometimes.
i have tried the little coin shaped silver squirrel whistle from time to time, with no effect that i could see. but it sounded good.
it's all done from the house. when i'm in the woods, i sit and wait. the mtn feist has done gone on, so no dog to help.
