The dang squirrels and ground squirrels have learned that peanuts are forthcoming when the bluejays start squawking and are poised and ready to grab 'em.
Unfortunately, the bluejays squawk a good game, but they are big chickens against those ground squirrels.
I need another feeder type :(

Saw a Video where the Bird Feeder was placed on a tall Pole.
They attached a Slinky to the bottom of the Feeder which ran down the Pole.
The Squirrels tried to climb the pole and the Slinky caused them to give it up.
