1. A chicken foraging 3.6 km/h

   Chickens can recognise over a hundred individual faces, both other birds and the humans who feed them.

2. A person walking 5 km/h

   The average person takes around 7,000 steps a day, walking the equivalent of several times around Earth in a lifetime.

3. A wild boar running 45 km/h

   Wild boars are spreading across the globe, rooting up so much soil they reshape entire ecosystems.

4. A running pronghorn antelope 97 km/h

   The pronghorn can run far faster than any predator alive today, likely escaping a cheetah that went extinct in America.

5. A golden eagle in a dive 245 km/h

   A golden eagle can spot a rabbit from over three kilometres away, then fold its wings into a lethal stoop.

6. A Bugatti Chiron at top speed 510 km/h

   The Chiron is electronically limited; unleashed, its tyres would tear themselves apart from the sheer forces.
