American Goldfinches, while wonderful birds, can create quite a mess under feeders when they arrive in a large flock. This year’s flock in my yard is huge. I already figured out how to solve the mess they made under the sunflower heart feeders. Now I’m working on the mess under njyer feeders.
American Goldfinches have been dropping a LOT of sunflower seed on the ground under my feeders. While some dropped seed gets eaten, some goes to waste. And sunflower hearts turn to mush on wet ground, making them an expensive mess. As always, it helps to first watch just what is happening at your feeders and then decide what to do.
