@elbanditoroso I have read that there are certain electromagnetic patterns on the earth’s surface that help them to navigate.
Where is that article, I would like to take a gander at it I wonder how they figure it works, the pigeons have GPS of some sort, if so, how does it work and why don’t every animal have it? Why does it seem only them, salmon, elephants and several other have it and some do not have it at all?
@ragingloli Migrating birds have little magnetic mineral deposits in their heads that enable them to read the planet’s magnetic field.
The paper(s) can be found where on the Net? Is there an image from a microscope that shows this, I wonder?
The truth of it, how they do it is how they were designed to do it. The manner and method is irrelevant, because unless it can be reproduced in other animals, there is no way to know if any thought of way would actually work. They do what they do, and man has found a way to make use of it.
