A few nice animal behavior images I found:
Pelican, Open Mouth 2
Image by jpmatth
again low quality. here it looks like his mouth has become inverted, but if you compare with the previous picture you can see that what he's doing is actually stretching the beak skin around his neck. i don't know if there's a reason for this behavior or not.

Ridiculously small, and yet very fishlike already, and showing all the behaviour of his parents.
