Again, there are clues and stories that seem to be throwing some light.
For instance, many kinds of birds are known to use star maps.
In the early weeks of life the baby birds sit in their nets and study the night sky- and are somewhat confused if those early weeks are too cloudy.
But they do not, as human amateur astronomers might do , spend their time learning the individual constellations - how to recognize Orion or trace the fanciful outline of Taurus, or whatever.
Instead, they focus on the part that does not move as the night progress, which in the Northern Hemisphere means the North Star.
They can see, if they look at it long enough, that as the night progresses, all the stars in the sky, including the mighty Orion and the notional Taurus, seem to revolve around the Pole Star, which sits in the middle like the central part of a giant cartwheel
Once they recognize the central part, the most fundamental problem is solved.
The creature that can do this knows where north is and everything else can be figured out.
I don't know what the equivalent would be in the Southern Hemisphere, but undoubtedly there is one.
Navigation simply does not seem to need the details of astronomy.
お礼
