Schnozzes

I know they are technically called beaks or bills, and that most of them are not used for breathing or smelling, but they can still be pretty funny:

Glossy Ibis:

Here is a question. How does the lower part of the beak know to curve down at the same rate as the upper part?

Costa-Rican Toucan (not the official name - this guy was in a zoo, and I didn't catch the proper name):


Black Skimmer:


Canada Goose:


Ruby-Throated Hummingbird. You might not realize it, but this guy is actually sticking its tongue at you. (The part of its bill that starts to curve down is where the tongue starts.)


Willet:


Juvenile Double-Crested Cormorant (I like the hook at the end of its beak...):
