The Bird Feathers Quiz – Facts Worth Knowing

Flamingos turn pink from the food they eat, while a peacock's shimmer comes from structure rather than pigment, and the bird feathers quiz explains both. Trace feathers back to dinosaurs like Archaeopteryx and learn why Charles Darwin found the peacock's tail so puzzling.

The Bird Feathers Quiz – More Than Just Flight

Feathers are unique to birds today and are made of keratin, the same protein as hair and nails. They help birds fly, stay warm, stay dry, attract mates and hide from predators.

Different feathers do different jobs. Flight feathers are stiff and shaped for lift, contour feathers streamline the body and fluffy down traps heat. Colors come from pigments, like the carotenoids that turn flamingos pink, or from tiny structures that bend light.

Fossils show that feathers first appeared in dinosaurs, including Archaeopteryx and many smaller feathered dinosaurs from China. Charles Darwin was puzzled by the peacock's tail until he developed the idea of sexual selection.
