A massive wading bird in the stork family. It breeds in Africa south of the Sahara, occurring in both wet and arid habitats, often
near human habitation. It is sometimes called the "undertaker bird," due to its shape from behind: cloak-like wings and
back, skinny white legs, and sometimes a large white mass of "hair." It shares the distinction of having the largest
wingspan of any land bird with the Andean Condor. This is the only species of stork to eat carrion and will often
gather with vultures at a carcass where it rules the roost, with even the largest vultures giving way to the
bad-tempered Marabou Stork.

The Marabou is unmistakable due to its size, bare head and neck, black back, and white underparts. It has a huge bill, a pink
gular sack at its throat, a neck ruff, and black legs and wings. Despite its grotesque appearance, the Marabou’s more
enlightened neighbors appreciate its efficiency in reducing disease by cleaning up carcasses and other rubbish.
