What is your favorite method of call for squirrels?

Al

Call ? No , sight !
Back in the time we collected and ate black walnuts we found the lure .We collected walnuts and removed the husks and put them into a rather large pile.Later the squirrels saw the pile and their reaction was wonderful ! It was as if they had found the gold at the end of the rainbow !! they ran to the pile , picked up a husk but it was empty. Picked up another - empty, another - empty .They went through almost the whole pile before they realized it was a fruitless search !!

Clicking two quarters together.

Twist two plastic poker chips against each other.

I just call them using my lips and plam.
