Don't know what it is about Kansas Rios but I hunt them on my farm in South Central,KS about half my turkey hunting time,rest in eastern Kansas for Easterns.
They seem to stay with hens 24 hours a day....last weekend I called one to 60 yds with two hens....worked him for an hour and crawled thirty yds and shot him...Good hunt in my mind....calling got them close and used terrain to seal the deal but not a classic ,come strutting in all the way hunt...but better than tag soup!
Good luck in Texas!
