What makes a bird a bird?
•Feathers •Wings •Beak •No teeth •Lays eggs •Bipedal •Lightweight skeleton •Migration
•Wings and tail •One side of the vane is wider •Strong barbules •Barbs run parallel and hook together to make the vane
•Everywhere (apart from beak, legs and feet) •Coloured only at the end •Helps the bird be streamline
•Little or no shaft •Soft and fluffy •Insulation
•Stiff with only a few barbs at the base •Mouth/eyes
A birds skeleton has to be lightweight so it can fly which is why they have hollow bones. A bird’s skeleton weighs less than its plumage.
