Beaks Vs. Bills

For a very long time I have been wondering what the differences is between Beaks and Bills.
 But at long last I have found out.
 A Beak is sharp much like that of a Hawk. And a duck has a Bill flattish and often looks rather rubbery.
 Birds of the water have Bills and the others have Beaks!
Bills are most commonly used for scooping up small fish and other stuff from under the water. (This is why ducks and other water birds have them.)

 Beaks are used for cracking nuts and catching prey.

What do you think this bird has? A bead or a Bill.

So there you have it. The difference between BEAKS and BILLS.
