Can Hummingbirds Open Their Beaks?

This is why I don't get as much work done as I'd like.  I thought I'd take a quick look at Google News (just to know what's going on in the world), and I saw saw this article: Hummingbirds Use Their Beaks As Weapons.  I don't know why I clicked on it, except that Hummingbirds are so beautiful.  I only glanced at the article, and then I wondered if Hummingbirds can open their beaks.  So I did a search on that.

In case you're wondering...yes, they can.  Here's a picture.
