Congrats @chmoen !!
"Bees navigate by the sun. It turns out that they read clues to the hidden sun’s position in polarised light ".
"Bees’ eyes can see the orientation of polarised light. Because sunlight passing through the atmosphere takes on a characteristic polarisation pattern that reveals the location of the sun, it has long been suspected that bees use their eyes’ special photoreceptors to navigate when the sun is masked by cloud".
