Why male wood duck looks llike that?


My explanation is : Firstly, need relationship selected the wood ducks taste. Lately, the female taste selected the males shape. Does not the head of the male wood duck look like a snail?

Wood duck is not alone. More pictures show how birds’ feathers reflect their needs of foods or enviroments:

Interesting theory,

On that note, it looks like some of its avian counterparts are really into UFOs.
