Not necessarily. You are projecting your own fears in that situation onto the bird, but the bird wouldn't have the same perspective.

As a human, your brain evolved over millions of years to only feel comfortable when you are standing on solid ground. Flying through the air is about the most alien experience a human brain can have, and it won't respond well to that situation.

But a bird's brain has evolved to be extremely high and not think twice about it, probably even enjoy it. Ever see a flying bird that didn't look happy?

So while you would be naturally freaking out at flying around like that, a bird would probably feel right at home, and relaxed.
