You're right. Birds are amazing.Birds are fascinating, both because and in spite of being living dinosaurs.
We often envy the spatial memory of birds, such as chickadees and magpies, when we misplace our items.
Our daylight eyesight is substantially poorer than most birds already, and we envy the natural HD eyesight and the super eyesight of birds, such as raptors (not owls here!) and ostriches.
Can we see like birds in daylight?
Flight without mechanical aids is a persistent human dream; can it be realized?
It sounds as if we break through the secrets of birds, we can fulfill many of our dreams.
There's a swallow that migrates all the way across Europe to Africa, and back, every year. They hatched some eggs and raised the birds indoors, then put them in a planetarium with a star machine at migration time. The birds would always orient themselves in the proper direction, indicated by the stars. When the stars were rotated to a different position, the birds matched it.
So, in the egg, the birds had some sort of star chart embedded in their brains ... but over years, the stars change a bit (with respect to Earth), and the birds must have some mechanism for adapting.
Their tiny brains must work very differently from ours.
Would you give up your arms to have wings? Cut down your legs to sticks to get rid of weight? You're limited to four limbs ... and maybe a tail.
