I agree with Tom Erdman that the title was a bit misleading. It turns out
that particular cells in one species are not what they thought they were. I
guess
they needed a "hook" to get people to read the article, and I suspect they
caught more than a few of us who are interested in birds. Not the major
discovery the title implies.

I'm sorry having read the report, I have to say that your title has does not
reflect the content of the report? Birds still use the earth's magnetic
field to navigate and there be many studies to prove that! Where the
sensory mechanism is, for them to do this had been shown not to be where it
was thought to be! Are you arguing that birds don't use the earth's magnetic
field? This paper offers no proof of that!

Research published today in the journal Nature throws cold water on the
theory that iron-rich nerve cells in birds' bills help them navigate using
Earth's magnetic field. Rather than finding magnetic nerve cells in pigeons,
the authors of the paper found specialized white blood cells that help birds
fend off infection.
I've summarized the research in a new post on our blog:
