Feeding birds?

I also live in Florida and feed birds like crazy! I put one of those on my mothers window and birds go to it most of the time. All the birds are just now coming back around this time of year. Try a mix, not all birds eat sunflower seeds. Dove are the easiest to attract and they like the millet and miso. Cardinals and bluejays like sunflower but cardinals prefer to eat off of a flat surface. Try putting some on the ground or on the sill to lure then in. Good luck.
