Marabou Stork Identification Guide

Key Field Marks

• Size: One of the largest storks in the world, standing 120-152 cm tall with a wingspan that can exceed 2.5-3.2 m.
• Head & neck: Bald, blotchy pink-and-grey skin covers the head and neck, giving it a vulture-like, unfeathered look; a long, pale pink inflatable throat pouch hangs from the front of the neck.
• Bill: Enormous, heavy, and straight, pale horn-colored — one of the largest bills of any bird.
• Body: Blackish-grey back and wings contrast with white underparts; birds often stand hunched with the bill resting against the chest.
• Flight: Unlike most storks, which fly with the neck extended, Marabou Storks fly with the neck pulled back and retracted, more like a heron.

Separating It From Similar Species

• Vultures can look similar at rest due to the bald head, but storks fly with legs trailing straight and the neck retracted, and lack a hooked raptor bill — the Marabou's bill is long, straight, and dagger-like rather than hooked.
• Lesser and Greater Adjutant storks of Asia are close relatives with a similar bald-headed, scavenging look, but they do not overlap geographically with Marabou Stork (which is African) and differ subtly in pouch shape and proportions.
• No other African bird combines this huge size, bald pink head, massive pale bill, and dangling throat pouch.

Where & When to See One

• Habitat: Savanna, open wetlands, floodplains, and increasingly rubbish dumps and urban areas near towns and cities, wherever a reliable food supply exists.
• Range: Widespread across sub-Saharan Africa.
• Behavior: An opportunistic scavenger, often seen alongside vultures at carcasses, but also wades in shallow water to catch fish, frogs, and insects, and will take eggs and nestlings of other birds.
• Season: Resident, though some local and seasonal movements occur in response to food and water availability.

Voice

• Largely silent; the main sounds are non-vocal bill-clattering displays given at the nest, along with occasional low croaks or grunts.
