Covered Patio Bluebird Feeder

I heard about this feeder in a Facebook group. It does keep out the jays. The bluebirds didn't take long to learn how to use it. I gave it 4 stars because it didn't come with instructions on how to remove one bar to create a perch and open the feeder up to train the birds to use it. Also, I have this on a raised deck and it's windy so it rocks and I occasionally find the metal dish somewhere in the yard. It would be nice if the dish fit a bit snugger and the 'perch' were a bit rougher to provide stability for the birds. Also the eyehole bolt allows the feeder to rock a bit. This feeder would be fine at a less windy site.
