We had 2 bluebirds visit everyday at our old house, I'd put out popcorn or crumbled cake/muffins/cereal whatever we had leftover for them to eat. They would fly in and grab some and off they'd go and within that same minute be back for another grab and this would continue til it was gone! They always were a pleasure to watch! Our new home we have minimal trees and surrounded by fields so we don't have alot of birds yet, I'll do the same though and put out feeders and houses this spring and hopefully they will come!!
