  3. Secondary bony palate
  4. Premaxilla
    top part of beak
  5. Dentary
    • lower part of beak 
    • mandible
  6. Cervical vertebrae
    average of 14-15 vertebrae (7 in mammals)
  7. Brachium
    humerus in wing (bone attaching to rest of body)
  8. Antebrachium
    • radius and ulna in wing
    • secondaries attach here
  9. manus
    • carpals, metacarpals, and phalanges in wing.
    • Primaries attach here
  10. Clavicle
    fused to form furculum
  11. Sternum
    may or may not have keel/carina
  12. Scapula
    Shoulder blade
  13. Uncinate process on ribs
    • bony protrusions from ribs which help to stabilize rib cage
    • helps with respiration
    • serve as attachment for scapula muscles
  14. Synsacrum
    • fused lumbar vertebrae, ilium, ischium, and pubis.
    • pelvic girdle
  15. Thigh
    femur
  16. tibiotarsus
    fused tibia and fibula
  17. Tarsometatarsus
    fused tarsals and metatarsals
  18. Toes
    phalanges

  19. What are A, B, C, D, and E?
    • A: Phalanges
    • B: Manus ("hand")
    • C: Alula 
    • D: Metacarpals
    • E: Carpals

  20. What are F and G?
    • F: Ulna
    • G: Radius
    • ANTEBRACHIUM

  21. What is I?
    • Humerus 
    • BRACHIUM
  22. Pygostyle
    • fused caudal vertebrae 
    • supports tail feathers

  23. 1-5
    • 1) Cranium
    • 2) Cervical vertebrae
    • 3) Ferculum
    • 4) Coracoid
    • 5) ribs with uncinate processes

  24. What are 6, 8, 10, 12, 14, 17, and 19?
    • 6) Sternum (with carina)
    • 8) Tarsometatarsus 
    • 10) tibiotarsus
    • 12) femur
    • 14) synsacrum
    • 17) pygostyle
    • 19) scapula
  25. Bird toes
    • first toe: hallux (backward one)
    • may have 2-4. After the first, they are called "phalanges __"
  26. Functions of feathers
    • insulation
    • camouflage 
    • UV protection
    • flight
    • display
    • sound production
  27. Contours
    • outermost feathers (top layer)
    • protection
    • controlled by muscles
  28. Semiplumes
    • for warmth; cross between contour and down
    • have a supportive rachis, as on contour feathers, but lack the hooks that hold the barbs together
    • feather does not form a vane and has a downy feather look
  29. Filoplumes
    • consists primarily of the rachis with no barbs or only a few isolated barbs at the tip
    • not controlled by muscles
    • ave sensory receptors next to the base
    • found below contours, thought to give sensory input on contour feather activity.
  30. Powder down
    • never molted 
    • only in some taxonomic groups
    • tips disintegrate, forming powder (for waterproofing?)
  31. Bristles
    • small contour feathers
    • lack barbs on the outermost part
    • have an especially stiff rachis
  32. Down
    • feathers to insulate 
    • barbules lack hooks
    • lack rachis
    • soft and fluffy feather
  33. Calamus
    • the part of the shaft closest to the bird's body
    • hollow and does not contain any vanes.
  34. Rachis
    • The distal end of the central shaft
    • the area to which vanes are attached
  35. Vanes
    • extend from each side of feather
    • A series of parallel branches called barbs make up the vane
  36. Barbs
    • parallel branches in feather structure
    • branches off vein
  37. Barbules
    branch off barbs
  38. Hooklets
    tiny hooks keeping barbules together
