The latest research indicates that both you and firemoon are right (or wrong):I believe in science, and all physical science can be reduced to quantum mechaincs if you want to. But all the evidence, except your reference points to birds navigating via magnetic field, and last time I checked magnetic fields are part of the invisible spectrum, even to birds.

See especially the section headed "Cryptochrome".
The possibility that birds’ magnetic compasses might be based on a light-induced chemical reaction in the eye was suggested by Klaus Schulten, now at the University of Illinois at Urbana-Champaign, in a far-sighted paper at a time (1978) when the radical pair mechanism was in its infancy. Only later, did Wolfgang and Roswitha Wiltschko, working at the University of Frankfurt discover that, as Schulten had anticipated, birds need (blue or green) light for their compass to work.
