Bird feathers display complex design and this phenomenon can never be accounted for by evolutionary processes. There is a shaft that runs up the center of the feather. Attached to that are the vanes. The vane is made up of small thread-like strands, called barbs. These barbs,... of differing lengths and rigidity, give the bird its aerodynamic nature. Each barb has thousands of smaller strands attached to them called barbules. The barbules are connected to barbicels, with tiny microscopic hooks, called hamuli. Each strand is hooked to an opposing strand, like the hooks of a zipper.
A crane feather has approximately 650 barbs on each of side of the shaft. Approximately 600 barbules branch off the barbs. Each of these barbules are locked together by 390 hooklets. The hooks latch together like the teeth on both sides of a zip. If the hooklets come apart , the bird can restore the feathers to original form by shaking itself or by straightening its feathers with its beak.

Charles Darwin .....
"I remember well the time when the thought of the eye made me cold all over, but I have got over this stage of complaint..." And then continued: "... and now trifling particulars of structure often make me very uncomfortable.... The sight of a feather in a peacock's tail, whenever I gaze at it, makes me sick!"
Norman Macbeth, Darwin Retried: An Appeal to Reason, Harvard Common Press, 1971, p. 131.

Darwinist, Ernst Mayr:
It is a considerable strain on one's credulity to assume that finely balanced systems such as certain sense organs (the eye of vertebrates, or the bird's feather) could be improved by random mutations .
Ernst Mayr, Systematics and the Origin of Species, Dove, New York, 1964, p. 296
