  13. Feather Types • Contour

  14. Feather Types • Contour • Outermost feathers

  15. Feather Types • Contour • Outermost feathers • Strong and stiff for flight

  16. Feather Types • Contour • Outermost feathers • Strong and stiff for flight • Each feather controlled by specialized muscles.

  17. CONTOUR

  18. Feather Types • Down

  19. Feather Types • Down • Used in insulation.

  20. Feather Types • Down • Used in insulation. • Very soft and fluffy.

  21. Feather Types • Down • Used in insulation. • Very soft and fluffy. • Barbules lack hooks.

  22. Feather Types • Down • Used in insulation. • Very soft and fluffy. • Barbules lack hooks. • Rachis is missing or reduced.

  23. Feather Types • Down • Used in insulation. • Very soft and fluffy. • Barbules lack hooks. • Rachis is missing or reduced.

  24. Feather Types • Semiplume

  25. Feather Types • Semiplume • Found between other feathers.

  26. Feather Types • Semiplume • Found between other feathers. • Help maintain warmth AND smooth shape.

  27. Feather Types • Semiplume • Found between other feathers. • Help maintain warmth AND smooth shape. • Cross between down and contour.

  28. SEMIPLUME

  29. Feather Types • Filoplume

  30. Feather Types • Filoplume • Simplest of feathers

  31. Feather Types • Filoplume • Simplest of feathers • Almost all rachis and few barbs.

  32. Feather Types • Filoplume • Simplest of feathers • Almost all rachis and few barbs. • Aid in structure and sensory.

  33. FILOPLUME

  34. Feather Types • Bristles

  35. Feather Types • Bristles • Very small contour feathers

  36. Feather Types • Bristles • Very small contour feathers • Highly specialized

  37. Feather Types • Bristles • Very small contour feathers • Highly specialized • Lack Barbs on outermost parts
