The Bug:

Sculk sensors are not activated upon a parrot dancing.

Steps to Reproduce:

• Spawn and tame a parrot.
• Play some music in a jukebox.
  →  Notice how when the parrot is dancing, the sculk sensor does not activate.

Additional Information:

Quote from the 20w49a Changelog, "A vibration is anything that causes physical motion". I would definitely consider this as physical motion, as the parrot is physically moving. This may be considered as a Feature Request.
