What you're describing is perfectly typical of trail cameras during the summer. Mine do the exact same thing. When the warm summer winds pick up, my cameras will take pictures every minute until the wind dies down. It's especially bad if there are leaf covered branches in the way being blown around. There's really not much you can do about it except to trim anything within the sensor's detection zone that might be blown around by wind.
