We have always said that the work of our hero David Kaeys is critically important in demolishing the magnetite cluster in the beak theory. This theory proposed that the magnetite group acted as a compass which enabled birds to sense the magnetic field and therefore use this for navigation.

I am delighted that other places such as this link confirms this work and gives more information. We are deeply skeptical of the idea that just knowing where North is is of any help to navigation as you need a map showing your current position and that of the destination to use a compass.

Magnetoreception – the ability to sense the Earth’s magnetic field

David Keays is one of the mega stars of animal navigation research and has spent a life time trying to work out how magnetism might work. Here is a summary of his latest work: Magnetoreception is the ability to sense the Earth’s magnetic field, which is used for orientation and navigation. Behavioural experiments have shown…
