Two male common grackles exhibiting their aggressive nature.
It was quite the battle: fast, vicious and long. Two male grackles pecked, clawed and beat their feathers as they struggled to get the best of the other combatant. No clear idea why these two were going at it but it might have been a dispute over food, they were under a bird feeder stocked with corn — a favourite grackle food. Or, it might have been a mating display. A female was watching from a safe distance.
