82 The Origin of Birds and Flight

One reason why the feathery display appears so attractive is that they
constitute a semi-circular fan with an angle greater than 180 degrees. This fan
is very regular, since every feather’s axis emerges from a common geometric
centre. The angles with which the feathers exit the center is also specific.

The peacock’s tail, large feathers, bright
color and unique patterns are extraordinarily
beautiful. T- and eye-shaped patterns are
arranged in a fan-like shape. The feathers’
showy appearance is based on a microscop-
ic level of complexity.
