White millet, sun-flower seed ( both varieties), and wild bird mix. Also, gravy train type dog food will bring in the grackles. I'm sorta preparing my "dove field" and top count this Saturday morning was around 20, seems like each time they show up, they bring a friend, HeHeHe!! They've gotten so used to me shooting and plinking, that they rarely fly off now. They also make great decoys along with the song birds that are under friendly surveilance,....Gracks, Starlings and Sparrows only,...until this fall that is! tjk
