Looks like you just have a large starling population, and if they descend mob handed then your expensive seed will all be gobbled.Go for cheaper feeding options, and DO throw some bread and bits on your lawn away from the feeding station perhaps.If all fails, have no open seed trays at all. just peanuts in wire containers and fat balls also in containers.It will last longer and they may give up sooner, leaving some for the small birds.Good Luck.
