Speaking of Cheetahs, pigeon fanciers like to compare their birds to Cheetahs. A 200gram grain-fueled homing pigeon can maintain 60km/h for an hour. A cheetah can do that for maybe a minute. I've always thought this is not really a fair comparison, as flying through the air probably requires way less energy than sprinting.
