Hi Paul!
I only can afford suet at this point. I have 3 suet feeders. One is the type that can hold 2 cakes and can accommodate the Pleated Woodpeckers.
When I did feed seed I put out black oil sunflower seed, Niger for the Goldfinch, and Safflower seed. My cardinals & house finch loved the Safflower seed but lots of people do not have much luck with it. I would also put some corn out for the crows & blue jays. I also had a peanut feeder. Plus the suet feeders!
I miss the variety of birds that I used to get in the yard but I don't miss the mess and having to clean up. When we are done with kids at home maybe I will put out seed again......maybe.
