In the area in and around Ames Plantation (home of the National Bird Dog Field Trials and the Bird Dog Museum) farming practices have changed very little and habitat has been tailored for quail but there has been little improvement in the wild quail population.
In the area there is probably less farming now than when we really had lots of wild quail.

Around Ames Plantation (Grand Juntion Tn.)the quail were gone before we had any turkeys. So I don't blame them.

Mr.Dunn of the old "Dunns Supply" at Grand Junction told me they had pictures of turkeys raiding a quail nest at Ames Plantation.
I do know a turkey will eat most any thing but I don't believe them to be smart enough to actively seek out a quail nest on a steady basis.
