Interestingly, this actually came up as a result of my predilection for exclaiming, "That's a hawk!!" as we're driving. (It makes little difference whether I'm the driver or passenger.) Though cows, sheep, etc. are certainly included. So are llamas. (We have a few llama farms around here. Or perhaps they're alpacas...)
I look forward to having the opportunity to shout, "There's a mollusk!!" and then rasp at it.
