As you can see from the picture below, one of the staff came in to fix the habitat. The stork felt threatened. He started making a loud wheezing noise.

Then he raised his head

and kept tipping it backwards

until his head was resting all the way on his back.

He then snapped his head back into place and stabbed at the ground. These storks are native to South America. Their wingspans can read four feet and they weigh up to eight pounds.
