30 Unusual and Unique Birds in The World

"Some feathers evolved as specialized airfoil for efficient flight. Others have been shaped into extreme ornamental forms that create impressive displays but may even hinder mobility. Often we can readily tell how a feather functions, but sometimes the role of a feather is mysterious and we need a scientific study to fill in the picture," Thompson explained.
A good example of one of these mysteries are feather tufts on the heads of Great Horned Owls (Bubo virginianus) which are often mistaken for ears. These modified contour feathers are completely separate from the ear and do not help owls hear, yet scientists can't explain the function of these tufts. Some think the horns are for display, others suggest that owls use them for more complete camouflage while roosting in daylight, but no one knows for sure.
