The marabou stork (also known as the adjutant stork for its style of marching about) is the largest of the storks. Its short, thick neck is largely naked and is a dull pinkish to brown in color -- the same as the bill. It possesses a naked, skin-covered pouch which hangs down one foot or more from his throat and appears to belong to the respiratory system. The marabou has no crop and an adult needs about 25 to 32 ounces of meat daily. This large bird is 60 in. long, has a wingspan of 9.8 ft. and weighs 11 lbs.Marabous have an enormous sharp bill, capable of dealing lethal blows. The birds are scavengers with bare heads and are found in association with vultures. The young take 116 days until they fly and leave the nest at about 130 days.
