I searched in this forum and no one has mentioned this. What are the thoughts of general physicists regarding Al-khalili presentation how the robin bird eyes use quantum entanglement? Searching at the net producing the following:

"They turned to results from recent experiments on European robins, in which the captured birds were exposed to flip-flopping magnetic fields of different strengths during their migration season. The tests revealed that a magnetic field of 15 nanoTesla, less than one-thousandth the strength of Earth's magnetic field, was enough to interfere with a bird's sense of direction (Biophysical Journal, DOI: 10.1016/j.bpj.2008.11.072).
These oscillating magnetic fields will only disrupt the birds' magnetic compass while the electrons remain entangled. As a weaker magnetic field takes longer to alter an electron's spin, the team calculated that for such tiny fields to have such a strong impact on the birds' compasses the electrons must remain entangled for at least 100 microseconds. Their work will appear in http://prl.aps.org/accepted/L/90079Ya1Ff316529366b47a0c9e2917fa594941b5 ."
Elsewhere I found the following how "The results were stunning, as the robins became disoriented and flew aimlessly around the room whenever the field was turned on. At 150 nanoTesla, the field was about 300 times weaker than the Earth's magnetic field, which means the birds should never have become disoriented unless they really were using quantum entanglement to navigate. It does seem to rule out the iron molecule hypothesis, as the field would need to be 100 to 1000 times stronger for iron to be affected."
As light enters the eye, it hits a protein called the cryptochrome, which surrounds the retina. Electrons in this protein are entangled, but light causes one part of an electron pair to get knocked out. The freed electron starts to wobble in reaction to Earth's magnetic field, but its still entangled brother also experiences these same movements and the magnetic pull from the rest of the molecule. The difference in how these two electrons move - because the free electron is no longer affected by the magnetic pull of the cryptochrome - creates patterns in the retina that the robin's brain can then interpret and use for navigation."
