Oh we'll see about that
*I start by focusing my chakra, allowing it to flow, them I picture my mind (if you will) and keep the chakra flowing, eventually after flowing my chakra with my mind, I merge the two. Then I thrust my hand out in front of me making a special handseal, I aim my hands at the bird you stated and release my mind from my body and send it over into the birds, allowing me to freely control the bird. I then make one circle around you in the birds body and release the jutsu, bringing me back to my mind.
Advantages- Can control opponents
Disadvantages- Whilst occupying someone else's mind you cannot control your own body
