[Cyborg] magnetic sense in birds

Wow, that's an awesome article you attached.  I especially love the conclusion:

<<
People unaware of these intriguing findings often ask me, “What does ultraviolet vision do for birds?” The question seems to imply that sensitivity to UV must be a peculiarity or even a feature that self-respecting birds should be able to live happily without. We are so locked into the world of our own senses that, although we readily understand and fear a loss of vision, we cannot conjure a picture of a visual world beyond our own. It is humbling to realize that evolutionary perfection is a will-o’-the-wisp and that the world is not quite what we imagine it to be when we measure it through a lens of human self-importance.

I am also fascinated by the idea that our third cone cell is merely a mutated clone of the second cone cell that birds have, you can see this in the spacing of the cones:

Birds:  370  445  508  565
Humans:     424    530 560

Clearly the vision of birds is not only better for being tetra-chromatic, but also better because "red" and "green" are spaced further apart!

I hope someone is researching gene therapy to give humans the vision of birds, cause damn, sign me up!
