Lower the pic quality from the settings menu from high to medium. It seemed to work for me - I know it doesnt make alot of sense though - give it a try.

Remove all brush and grass from the area you're taking the pic's.
x2 Any thing that blows in the wind close to the camera will trigger it I always clear about 4 feet in front of the camera.
+1 It's frustrating to see 50 pictures of a weed or limb due to the wind. Took a couple of months for me to figure what was causing it.
I put a prowler 1 month before the season 2 years ago. Got the card out of it I was amazed day before opening day had 1009 pics, 1006 were wind moving a little twig I missed.
