A discarded hero sandwich bread lay discarded on the steps leading to Riverside. I knew this would draw somebody, so stopped to wait. The first to arrive was the starling,... tentative.... one bite, then fled. It backed off knowing the grackle would not share. Food-orgy time. The grackle was feeding for a family. That's the only time you see such a routine. Think of a little kid stuffing a whole pizza slice in the mouth. Same routine. The grackle has "ownership" down pat, hold down food with claw and demolish the food. It went back a forth several time, delicious treat for nestlings. A little while later there wasn't a single crumb left.
