Woodhaven Calls Ninja Owl Turkey Locator Call - There is no better locator call to use in the spring turkey woods than that of a barred owl. The "Ninja Owl" is designed by Grand National and US Open Owl Hooting Champion, Scott Ellis. From those high-pitched screams and laughs, to the original 8-note hooting sequence, the "Ninja Owl" delivers a user friendly call with a championship quality tone and sound.
