Silent flight

Why can an owl fly almost silently? The owl hunts at night and wants to make as little noise as possible in order not to frighten his prey.

Feather facts

Feathers appear to have evolved from scales and are composed of B-keratin. Scales and feathers develop in a similar fashion. In actuality, birds have both feathers and scales. You can find scales on the legs and feet of most birds.

Feathers are incredibly strong and yet are incredibly flexible. To allow both lift and forward movement, feathers can bend at almost a right angles.
