HummingBird and Responsive.menu

Hi there,

I'm running trying to use Responsive.menu https://responsive.menu on my site, but there seems to be a conflict with Hummingbird.

When I have both plugins activated, I'm getting the following message in the error console:

"ReferenceError: jQuery is not defined[Learn More]"

I've got a coming soon page up right now, but you can access the site at this link: http://oakvilleperiodontist.com/splash/

Do you have any insight into this?

Thanks,
