Heads up about that cheap birdseed mix from the grocery store
I just read a study from the Cornell Lab of Ornithology that found some budget mixes are over 50% filler like milo and wheat, which a lot of common backyard birds just won't eat. I checked my own bag and sure enough, the ground under my feeder was covered in wasted junk. Has anyone found a good, affordable brand that doesn't have all that filler?
