Last night as I was walking home from the bus I saw a hawk (falcon? It was smallish, anyway) trying to catch a sparrow, who was fluttering frantically in an ultimately successful attempt to dodge. The sparrow had a better turning radius.
A few seconds after I spotted them the hawk gave up and settled on a roof, with an attitude I am intimately familiar with from living with cats: "I meant it to come out that way, why do you ask?".
When I see that kind of thing I'm always torn. The predator has to eat, and has the charisma of being a predator, but I always feel sorry for the prey, too.
I'm reminded of the best thing ever written about the woodpecker (or
probably any bird):
Will Cuppy, early 20th century humorist, in "How to Tell Your Friends from
the Apes" He's one of my favorite writers.
