Question

which bones of the brid and helpful in moving wings up and down​

Answer 1

Explanation:

Breast bones in birds hold flight muscles that help them to move wings up and down.

Answer 2

The bone is sternum.

• For flight muscle attachment, active birds naturally have an extended breastbone typically called as a sternum.

• The pectoralis major, which lowers the wings and the supracoracoideus, which raises them, are two considerable muscles that move the wings of birds during flight.

• This necessary positioning aids the birds in amply supplying the requisite thrust power. A pulley like movement is accomplished by a tendon that aids in their flight.
