Caption

Researchers have discovered that the long sought after protein in migratory birds are situated exactly here at the outer segment of the so-called double cone photoreceptor cells in the retina of the bird (this is a European robin). Cry4 is unique to birds and therefore could endow them with the sixth sense.
