I figured there had to be some sure-fire way to deter these birds from hanging in our yard. From the websites I visited, the most popular deterrent seems to be simply spraying them with a garden hose or purchasing a motion sensor water sprayer. Can their brain even remember this? The automatic hydro-sprayer costs about $60. One site suggested chasing the turkeys with a broom and "encouraging" them to go away. You can even purchase a propane cannon for over $200 - I'm getting visions of Wile E. Coyote and Road Runner.
Funny part is, it seems that holding a camera must be just as good a deterrent as a garden hose, because whenever I try to take a photo of said turkeys (and I have tried on numerous occasions), they scatter or fly away quicker than I can blink. Yes, these huge things actually fly too! And it's not pretty.
So here is a photo of the remaining wet turkey tracks on our driveway. The turkeys have vanished...for now anyway.
