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.

How do you feed ground-feeding birds like sparrows in heavy snow? If you toss some seed on the ground as usual, it might be snow-covered within minutes. Birds won’t be able to see it and so might find it challenging to eat. The solution? Provide some cover!
