| A type | Structural features | Body location | Value |
Contour | Rod of medium length, small fans | Whole body | Increases airflow during flight |
Flight feathers | The rod is long, the fans are wide, they run almost along the entire length of the rod | Wings | Creates a flying surface for the wing, provides forward movement |
Helmsmen | Larger than contour, but shorter than flight feathers | Tail (tailbone) | Adjust the direction of flight |
Downy | The shaft is thin, flexible, barbs do not form a fan (no hooks) | Whole body | Keep warm, participate in thermoregulation |
Hairy | The rods are thin, no barbs, protrude above the surface of the contour feathers | Whole body | Participate in touch |
