The word Dove is found in the King James Bible 19 times, the word Turtledove 3 times with all three being references to using them as Sacrifices. When an animal or fowl was sacrificed it was "Killed".
The phrase "Bird of Peace" is simply not found at all, so that phrase is man given & not inspired.
