Best way to attract them.......Plant some crop you don’t want them to eat. They’ll come running and bring friends.
Second best....... A pile of corn. About a 5 gallon bucket full for starters. That seems to get their attention. Then as time goes by just enough to keep them returning.
However it goes without saying that you have to have some in the area in order to attract them.
