A Duck Pond Darwin Emerges!

Though not the actual ducks inhabiting the small artificial pond in my school's courtyard, this picture (taken on June 7, 2008 by my wife and I) is pretty representative of what I have observed outside my classroom window.
Following up on yesterday's post concerning my school's courtyard duckpond, of course, someone piped up with "a mean, sarcastic email" in response to one person's request for solidarity in protecting the ducklings which were recently hatched.

In her original e-mail, Employee X, a professional in the school who is not a classroom teacher, asked for volunteers to consider bringing in "Owl statues, or something similar" to be "placed in the courtyard to scare away the crows." Apparently the crows were snatching up and, presumably, eating the ducklings.

So here is the e-mail which was sent out to all staff in response to Employee X's query:

When you say "we" would all like to see them survive, are you including the crows? I have to believe that 5-day old baby duck is a delicacy for those crows.

I vote for natural selection. I'm a big crow fan. As a matter of fact, lets video tape it and show it in our Living Environment classes.

C. Darwin

It's important to note that "C Darwin" also signed his real name to the e-mail and used only the pseudonym in the body of the letter. Any guesses as to what class this individual teaches?
