African stork ( Leptoptilos crumeniferus ).
Standing 5 ft (1.5 m) tall with a wingspread of 8.5 ft (2.6 m), the marabou is the largest of all storks. Mainly gray and white, it has a bald pinkish face and neck; a reddish, inflatable throat pouch; and a straight, heavy bill. Marabous eat carrion, often feeding with vulture s, which they dominate.
