Fascinating feathers


From left: Barn Owl, primary; Laughing Kookaburra, primary; Masked Lapwing, tail feather; Figbird, secondary, Laughing Kookaburra, tail feather; Bush-stone Curlew, primary.
Primary feathers: outer feathers of the wing, provide thrust and propel the bird upward and forward;
Secondary feathers: provide lift by creating the airfoil shape of the bird's wing;
Tail feathers: help the bird to brake and steer in flight.
