The Peregrine Falcon is known for its extreme
diving speed, greater than 200 miles/hour (320 km/mi), the highest speed of any creature known to man. This is partially due
to stiff feathers and an aerodynamic teardrop shaped body.

The falcon shows advanced design in many other
ways including black patches on its face similar to a football player’s eye black. This shading minimizes glare to allow
focusing on its prey. Falcon eyesight is protected by a “third eyelid” which clears and lubricates the eyes during
rapid flight. It pulse rate can reach 600-900 beats per minute, carrying oxygen throughout the bird’s body.
There are hazards to high speed flight. Mainly,
breathing becomes difficult and high wind pressure can damage the lungs. To compensate, the falcon has specialized cone-shaped
bones near its nostrils, called baffles, which deflect shockwaves of air safely away and allow controlled incoming air for

Jet aircraft face a wind problem similar to the
peregrine falcon. When they move at supersonic speeds, their engines can “choke”. This means
that air moving in front of the engine appears to hit a wall of resistance and flows around instead of through the engine
and stalling results. From studies of the falcon’s nostril, engineers fashioned a metallic cone in the opening of the
jet engine. They found that air entered and fed the engine as required for flight. The aircraft cones can be observed at the
center of large jet engines. They are a successful solution to a serious flight problem, supplied by the Peregrine Falcon.
Nature is filled with similar useful ideas and
solutions to problems, provided by the Creator at the beginning of time. One by one, we discover these ideas and make improvements
to technology. Such examples of intelligent design in nature reveal the fingerprint of the personal, loving Creator.
