In the late 80's they released a line of toys called "pretenders" some mimic'd humans, or human formed Monsters or Animals.

Having said that, only the Autobots had "human" pretenders, the Decepticons had monsters and Animals.

I would imagine that this is where the original idea for that bird was.

Just to show what a huge sink hole that film was budget wise, they had Digital Domain work on a 2 second shot for three months. [no]
