Nothing to be worried about lol,

That bird probably just wanted to meet and greet you but instead you got a little shock from it hehe, Shiney (My lovebird) fly's to my shoulder's all the time she usualy just comes to me to relax and get a free ride around the house or to sing LOUDLY in my ears lol ... that bird ment no harm as many pet birds will do this.

The other day Shiney was on my shoulder when he flew over to my mom and freaked her out lol!!!

That bird must like you because usualy birds can be scared of strange people that they don't realy know.
