How to keep black birds away from my small bird feeders?

Use small feeders with tiny perches. Birds don't like sitting on perches that are smaller than they are. You might also throw some seeds, crumbled cookies, bread crumbs, etc... on the ground. Most large birds actually prefer eating on the ground.

i hope someone has an answer for u,,i have tried alot of things with no results,,,black birds eat alot of bugs so its a trade off

I say shoot them
