Finch seed socks may be the simplest of all bird feeders. I first saw them at a garden center where a tree had a dozen of these socks hanging beneath the canopy in the shade. The whole place was a finch mob scene and these bright yellow and orange birds were flitting around there in flocks. Naturally I had to have some because the whole idea was so simple.
Anyone with a needle and thread can whip one up in an hour if you have the right fabric. It’s simply a tube bag with a draw string at the top. Ready made socks are sold at most online or local pet or wild bird supply stores. The socks are filled with black thistle seed which can be bought in large quantities. The tiny black seed doesn’t pass through the net but the finches can reach in and get it with their sharp but stout little beaks.

There is but one caveat about finch socks. Be prepared for a lot of birds including non-finches too. Once they discover your source they can deplete a whole bag or more each day. Hang near windows to enjoy from indoors or spread around your garden to create a golden finch sanctuary.
