Another great find on Twitter, for geography, biology and physics classes.
How do birds navigate, compared to, say, Columbus? Most U.S. history texts make a big deal of Columbus’s navigation, made possible by invention of the magnetic compass and the sextant.
Birds are more accurate, and they have neither. Well, they don’t have external magnetic compasses. See the cartoon.

Neuroscientist and cartoonist team up to talk about birds “seeing” magnetic lines of the Earth! Information from Dwayne Godwin at Wake Forest University School of Medicine, with drawings by Jorge Cham, who draws Piled Higher and Deeper.
Teachers, have someone in the drafting department make this cartoon into a poster for your classroom.
As usual, the truth is more weird and wonderful than fiction writers could hope to invent.
Tip of the old scrub brush to Columbia University’s Twitter managers.
Birds are amazing in this area and without GPS!
