skeleton of a bird
furcula
Bone resulting from the fusion of the lower portion of the two clavicles enabling the wings to spread.
phalanges
Portion of the wing formed of articulated bones bearing the primaries.
carpus
Portion of the wing formed of two short bones; it is located between the radius, the ulna and the metacarpus.
ulna
Long sturdy bone located between the humerus and the carpus bearing the secondaries.
radius
Long wing bone located between the humerus and the carpus.
humerus
Long wing bone articulating especially with the radius and the ulna and bearing the tertials.
synsacrum
Long bone resulting from the fusion of numerous vertebrae of the vertebral column, preceding the pygostyle.
pygostyle
Bone of the terminal end of the vertebral column resulting from the fusion of several vertebrae.
pubis
Ventral bone posterior to the ilium.
ischium
Bone behind the ilium; the ilium, ischium and pubis fuse together to form a single bone to which the leg is attached.
ilium
Large flat back bone fused mainly to the synsacrum.
femur
Long bone articulating especially with the tibiotarsus.
tibiotarsus
Separate at the crown, the tibia and fibula fuse into a single bone to form the tibiotarsus.
digits
Each of the four terminal ends of the legs formed of different articulated bones called phalanges; most birds have four digits.
sternum
Bone located at the ventral portion of the body and bearing the keel; the ribs are attached to it.
keel
Bony ridge of the ventral surface of the sternum providing a solid support for the flight muscles.
rib
Thin curved bone articulating with the vertebral column and the sternum.
coracoid
Ventral bone connecting the scapula to the sternum.
clavicle
Long bone located in the anterior ventral portion of the body; the two clavicles fuse to form the furcula.
scapula
Large flat back bone. The juncture point of the scapula, clavicle and coracoid; the wing is attached to it.
cervical vertebrae
Bony parts of the neck comprising the upper terminal end of the vertebral column.
mandible
Bone forming the lower portion of the bill.
maxilla
Bone forming the upper portion of the bill.
orbit
Bony cavity of the upper lateral potion of the head containing the eye.
skull
Bony structure enclosing and protecting the brain.
