While I'm happy that they have brought back the effect, I have to say that with all of the technology available at the time they built EE, that bird is about the
saddest, low-rent, mechanical effect Disney has installed.
It's a motionless "toy bird" on a stick.
You can clearly see the stick, and the motion (when there is any) is very jerky and unnatural.
Come on, Imagineers!
The very FIRST publicly-seen AudioAnimatronics ever installed by Disney were BIRDS (the Tiki Room)
and THEY'VE looked pretty realistic since the 1960's!
(Now, how about that YETI!)
