> We've already jumped to assuming the birds are annoyed?

If our displays flicker to them, which is a highly probable, it is annoyance by any definition. It may be not annoying to spiders which have a tiny brain and live in a world of mechanical sense, but birds are smart and most of their brain is shaped for visual data.

> A hindrance, but better than what came before?

How can this statement be applied to birds? They neither expect nor desire all these technology and the only reason they are not scared of it is a professionalism of their caretakers.
