Tuesday afternoon I glanced out my office window and was immediately mesmerized.
A peregrine falcon was flying by, pumping hard, carrying a heavy burden. He'd killed a pigeon over Carnegie-Mellon's campus and was taking it home to the Cathedral of Learning to eat.
Carrying prey is strenuous work. On average, a pigeon weighs 354g while a male peregrine weighs 612g (females average 976g). Imagine that your lunch weighed more than half your body weight and you had to carry it half a mile before you could eat. No way! That's why we invented wheels.
And so I watched, unable to continue working while the peregrine slowly disappeared in the distance. My desk job is easy compared to a peregrine's work.
