Feathers under 4x Magnification

Primary (flight feather) You can see the shaft down the middle and that the vanes hook together to create a smooth surface so the bird's wing will generate lift.


Down (under feather)  You can see the shaft down the middle and that the vanes do not hook together, so the feather remains soft and fluffy.  This makes it really good for trapping air and insulating the bird.
