I did some more research on Wikipedia and it explains that it's been a difficult bird to classify. Although previously thought to be related to the stork, now apparently it's closer to the Pelicans or the Herons.
Here's the image used on Wikipedia
The Oliver Austin book contains some interesting information about how the bird: it averages around 4 feet tall and it's bill is able 8 inches long. Its range is the papyrus swamps of the upper White Nile River and its tributaries into East Africa. Its bill has been adapted to poking around in the mud for lungfish and garfish.
According to Wikipedia, it's listed as Vulnerable on the IUCN Red List and there are between 5,000 and 8,000 of them left due to loss of habitat and hunting.
