Many folks often ask for seed that the "Blackbirds" and/or the Squirrels don't like, but one that will still bring favourite backyard birds to the feeders. The answer - Safflower Seed!! While the seed may somewhat limit the variety of birds, it is one that Blackbirds & Squirrels "generally" don't care for. (There's been some exceptions....) One thing is for certain, Cardinals, House Finches & others do!! They've been steady visitors to the feeder pictured below. We've seen Chickadees, Nuthatches, Woodpeckers check it out too. You'll want to make sure you have Safflower in your feeders to welcome the Rose-breasted Grosbeaks - They love it! They'll be here in about two months.
