According to the article 'How birds use Earth's magnetic field to navigate by Peter Meredith' in the website Australian Geographic (check it out!), there scientists sort out things to prove and give details about what and how birds use magnetic fields to navigate.
Facts I found out:
-Migratory birds can't tell that what their heading is either south or north, what they just look for is just it's 'equator-wards'.
Something I found interesting and surprising:
- These birds have this protein in their retina that creates a chemical reaction into the Earth's magnetic field and this way they use it as their compass.
A question I am pondering:
- I wonder if other kinds of birds can also use Earth's magnetic field as their navigator( because it says there in the article that only 20 species can only use those)
