I have been feeding cardinals, jays, finch and wren for several years. This year, the doves overwhelmed me, cleaning out each feeder within minutes. I spent many hundreds of dollars buying a variety of feeders to deter them, but they managed to either grasp, break or breakthrough all of the barriers. Someone at a local Audubon meeting suggested that I stop feeding everyone for a couple of weeks, the doves would go elsewhere, and then I could start over. That was the first of August. I put out a feeder a week starting late August, have tried a variety (suet, nijer, flat bowl of black oil sunflower {my preferred seed}, peanut/corn) and have had nothing, not even grackles or doves. Will anyone come back?
