If crocs couldn't catch a duckbill what did they catch that was slower? Fish?
You seem to think that a croc runs out of energy after swimming a few feet.
I think you are way off in your assumption. Watch the next Discover show
about crocodiles and I think you will get a different picture.

I find this hard to believe. For one you are naming human characterstics
that I seriously doubt crows have. "sarcastically", "contempt", "defying
me". Come on.

Big if. Besides crocs and other "dumb" reptiles eat birds. (Snapping
turtles, snakes, - Discover showed a turtle in Africa that grabbed a bird
by the waters edge and a bunch of the turtles actually chased the wounded
bird on the shoreline.)
