We also have a bird feeder on our deck.
One day a bluejay stopped by. The feeder had run low enough that he couldn’t reach what food remained, so he got right in front of the window and yakked and screeched up a storm.
As Mark Twain said, no other bird can cuss like a bluejay.
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 :(
