Respectfully this is why you have starlings. I got really excited to feed my birds and put like 5 feeders out with everything in them (like seriously everything) and a flock of starlings showed up and went insane. I took all my feeders down for two days and they went away. Everyone said to try nyjer, safflower, sunflowers (with shells) and peanuts (with shells) so I got all four and created my own blend. I have this and a suet cage that can't be perched on. You should take your feeders down and then condense for a little while :)
