Dan Sprague and the other crane handlers and pilots use a puppet head resembling
an adult Whooping crane to teach and encourage the chicks in all parts of
training. For example, they use it to get the chicks to follow the trike
during training. The handlers wear the long crane puppet on one arm and
use their feet to steer the trike. The crew rigged up the puppet head so
they could pull a lever and dispense mealworms to the chicks to reward them
for following. A small recorder in the puppet plays a soft crane sound called
a brood call or contact call to
the chicks, just like a parent crane would sound. The crew fondly calls
the puppet head "Robo-crane" because it's like having a robot
helper.

Why is such extreme care taken to hide any human forms or sounds from the young
cranes? What suggestions, if any, can you think of to improve Robo-Crane?
