Returning Search Bar to Menu in Twenty Eleven Theme

Hello everyone! I just recently updated WP and for some reason, the search bar on my site is no longer on the menu bar but hovering over a widget, just below where it should be. I’m not terribly familiar with CSS, but would someone be able to tell me how to get the search bar back into the menu bar?

The site is http://www.fly-brother.com. Thank you!!
