I finally made it to the store yesterday to get a big bag of black oil sunflower seeds - evidently the only seed my bird friends care for - within minutes of dumping the feeder and refilling it I had three male cardinals, Miriam (the female), wrens, a hermit thrush, and unidentified warbler, a flock of titmouse, and the chickadees. When they finished a young squirrel made its way over. I scared it when it was time for me to go.
This lesson is officially learned - Black Oil Sunflower Seeds ONLY.
Welcome back friends.
