Well, that use to be that way with opening day of pheasant season but that is now going away as our the numbers are down. There are parts of Iowa that are still good but you have to go west or LapLand, ( That's where Missouri laps over into Iowa.Seriously? Here in Texas opening day is almost a religious holiday.
My understanding is that Dove in Iowa, are considered song birds and that is why you can't hunt them. Sportsman have tried but to no avail. I have also hunted Doves in Texas but I guess they don't sing as well as Iowa Doves..
Be Safe !!!
