His real name is Sir Evelyn Anthony Peregrine Scathe, so of course he's called Billy, and we're thinking of getting engaged.

A humerus some 9,000 years old (i.e., after the last ice age) from the Aswan area in Sudan, where Falco peregrinus minor occurs today, was identified to belong to the peregrine.

And you'll see in the example with the starlings, with the birds, when this peregrine hawk is about to attack them, that actually waves of panic can propagate, sending messages over great distances.
