A juvenile Wood Stork feeding in the shallows at Pinckney Island NWR in South Carolina. |

They had their bills open in the water, waiting for a fish or crab to make contact. After a while, I got out of the car, crossed over and sat down behind the grasses.

Woods Storks have a unique way of catching their prey. They like to forage in shallow water with large concentrations of fish or crabs where they hold their bills open in the water. When a fish or crab makes contact with the bill, it triggers a snap-shut reflex, and the Wood Stork nabs its dinner without ever having to see into the murky water. Because Wood Storks are tactile feeders and do not have to see their prey to catch it, their method of feeding is called "grope-feeding" or "tacto-location."

Wood Storks are doing well in Georgia and South Carolina, and the government is thinking about changing their status from endangered to threatened. Click here for an NPR article and broadcast of the story.
Wood Storks are large birds. This guy was over three feet tall. I loved watching him move slowly through the water. |
In part two of this series I'll focus on the adult Wood Stork's face, so you can see how different a juvenile and an adult look. I took these photos on June 19, 2012.
