15 July – Kestrel magic

Today I saw a kestrel seeming floating on the breeze,
looking, for all the world, totally at ease.
But this sight transpired to be optical illusion,
for the bird was not still but in constant motion.
When they suspend they are really flying swiftly,
matching speed to opposing currents completely.
How do they judge an equation so precise –
let alone while looking so far below for mice?
Science and sorcery meet among the thermal winds,
while we drive past and on towards town and prosaic things.
