My wife and I feed squirrels. Sometimes it attracts aggressive blue jays. She chases them away. I point out that most people like blue jays and would consider the squirrels the thieves.
Yesterday, a blue jay came and she chased it away. It went to a nearby tree and cawed.
“Don’t call your friends!” she yelled.
Many blue jays came.
She went into the house and gave me strict orders to defend the peanuts.
