Falcons

Another example of the Golden Ratio and Fibonacci numbers in nature is the falcon, specifically the peregrine falcon. The peregrine falcon has fixed eyes, like an owl. This falcon is a meat lover, so when it comes to eating field mice or picking seeds from a bush, the peregrine falcon will prepare for attack. Soaring at speeds up to 320 kilometers per hour, the peregrine falcon readies to spiral down. The falcon keeps its prey in its sight until it is slaughtered. Nature compensates for its fixed eyes with the Golden Spiral. That’s right, the Golden Spiral. When a peregrine falcon catches its prey, it swoops down in a spiral which we call the Golden Spiral. Tilting its head at a 40° angle, the falcon can keep an eye on its prey. As you can see in the picture below, the falcon starts out making wide turns and quickly narrowing its distance from itself to the prey by closing in on the spiral.
