Question

why is the motion of bird's wing an example of oscillatory motion ​

Answer 1

Answer:

The bird changes its course every second thus creating a transverse wave of the motion, however, periodic motion is around a fixed point in a fixed interval of time for example-vibration of tuning fork.
