'Eye bath' to thank for quantum vision in birds

Bad article - what the title calls an "eye bath" and the article calls a "cellular bath" is really a "bath of hyperfine nuclei with 1/2 spin" (aka molecules?) which the electrons are interacting with.

Basically, many bird eyeballs can entangle electron pairs for much longer than human scientists can, and we want to know how. We believe the electron entanglement gives these birds some kind of sensory data about the earth's magnetic field.
