After years of suffering from large numbers of sparrows visiting my feeder, I have found a cure that is working. I put a link (for reference) below to the feeder that I am using but what I did was block off 8 of the 12 feeding ports and only leave the middle 4 open. I have more of every species visiting the feeder now EXCEPT the sparrow numbers are WAY down. What appears to be happening is the larger flocks of sparrows are not patient enough to wait their turn and are too aggressive with each other to feed with two sparrows so close together and the sparrows fight constantly. Only one sparrow will try to feed while other sparrows constantly try to muscle in and after only a minute the whole lot of them just fly off with most of them not ever getting to the feeder. After about a month of using this system, the larger flocks of sparrows are beginning to ignore my yard and feeder more and more.
