Look at the mess I created! These birds are going nuts (so to speak) for the all-you-can eat, all-day breakfast buffet. That feeder was filled yesterday morning. Half way down in the course of a day. Then they fight when there are rungs that don't have access to food. I image the female cardinal speaks Australian for some reason and is calling me out for not refilling the feeder faster. I have counted 14 to 15 birds at a time. They are relentless.
