Whistling co-worker

I have a co-worker that whistles and makes whistling/bird sounds from the moment he enters the building all throughout the day. I’ve gone to HR she’s claimed to have “ran it up the pole” to the GM and other management and supervisors. I know of 8 other co workers who have made complaints but instead of doing anything for asking him to quiet down or find some type of relief or middle ground because if we cannot eliminate the whistling in total we can @ least compromise right, they have retaliated against the people who have made complaints, I don’t get it and I cannot get any real answers or resolutions for the matter. I have resorted to trying to catch this guy using heavy machinery improperly so I can report him to OSHA sounds extreme but it’s really my only option I feel, I’ve also gotten a security license and started a 2nd job on the weekends but this place is 15 minutes from my home and outside of him this place is pretty decent.

(Sorry for the video quality hope it does justice)
