“It now appears that birds may visualize the earth’s magnetic field through a form of quantum entanglement, which is just as bizarre as it sounds. Quantum mechanics dictates that two particles, created at the same instant, are linked at the most profound level—that they are, in essence, one thing, and remain “entangled” with each other so that regardless of distance, what affects one instantly affects the other. No wonder the technical term in physics for this effect is “spooky action.” Even Einstein was unsettled by the implications. Theoretically, entanglement occurs even across millions of light-years of space, but what happens within the much smaller scale of a bird’s eye may produce that mysterious ability to use the planetary magnetic field. Scientists now believe that wavelengths of blue light strike a migratory bird’s eye, exciting the entangled electrons in a chemical called cryptochrome. The energy from an incoming photon splits an entangled pair of electrons, knocking one into an adjacent cryptochrome molecule—yet the two particles remain entangled. However minute, the distance between them means the electrons react to the planet’s magnetic field in subtly different ways, creating slightly different chemical reactions in the molecules. Microsecond by microsecond, this palette of varying chemical signals, spread across countless entangled pairs of electrons, apparently builds a map in the bird’s eye of the geomagnetic fields through which it is traveling.”

“Like all hunters, the peregrine is inhibited by a code of behaviour. It seldom chases prey on the ground or pursues it into cover, in the manner of other hawks, though it is quite capable of doing so. Many adults take only birds in flight, but juveniles are less particular. Peregrines perfect their killing power by endless practice, like knights or sportsmen. Those most adaptable, within the limits of the code, survive. If the code is persistently broken, the hawk is probably sick or insane.”

“They share a lot, astronomy and childhood. Both are voyages across huge distances. Both search for facts beyond their grasp. Both theorize wildly and let possibilities multiply without limits. Both are humbled every few weeks. Both operate out of ignorance. Both are mystified by time. Both are forever starting out.”
