Question

DEFINE ANY BIRD skeleton WITH STRUCTURE ? ​

Answer 1

$\bf \colorbox{yellow}{♡Answer♡}$

Birds have a lightweight skeleton made of mostly thin and hollow bones. The keel-shaped sternum (breastbone) is where the powerful flight muscles attach to the body. Birds have a smaller total number of bones than mammals or reptiles.

Answer 2

Ostrich:

Flightless birds, such as ostriches, lack a keeled sternum and have denser and heavier bones compared to birds that fly. ... The side of the chest is formed by the ribs, which meet at the sternum (mid-line of the chest).
