Catch Full Screen Pro: the header is not responsive

Hi, I just found out the header of my site in mobile device is not responsive (it only show the "zoom-in" of the top-left of the image). However, when I tried to scale the browser into mobile size on a computer, it worked just fine. The link of the site: http://www.butihaveseentheearth.com/farmdesign/ (Hope you can check that) Thank you very much and I am looking forward to your reply. Best, Kai
