A giant of unusual appearance

The marabou stork is a large bird of the stork family, of unmistakable and somewhat grim appearance. It has a head and neck almost entirely bare of feathers, of a mottled pinkish colour, and a long, massive bill. From its neck hangs a conspicuous inflatable pouch of bare skin. The plumage of the back and wings is dark, while the belly is white: seen from behind, with wings folded like a cloak and skinny legs, it vaguely recalls the figure of an undertaker, so much so that in English it is nicknamed the 'undertaker bird'. It is famous above all for its wingspan, among the largest of any land bird.

Habitat and distribution

It lives throughout sub-Saharan Africa, in a great variety of environments: savannas, marshy areas, river and lake banks. Thanks to its extraordinary adaptability, it has come very close to human settlements, where it frequents markets, abattoirs and landfills in search of food.

Feeding and behaviour

The marabou is above all a scavenger: it feeds mainly on carrion and animal remains, often in the company of vultures, with which it shares the role of 'cleaner' of the savanna. The bare head and neck are an adaptation to this way of life, because they stay cleaner when the bird thrusts its head into carcasses. It does not, however, spurn live prey: fish, frogs, insects, small mammals, birds and even food waste near towns. In flight it exploits rising air currents to glide for long periods with minimal effort.

Curiosities and conservation

Despite its inelegant appearance, the marabou plays a valuable ecological role, clearing the environment of carcasses and waste and limiting the spread of disease. It is classified as a species of least concern, with large, widespread populations, favoured precisely by its ability to exploit the waste produced by humans.

Pros

  • Among the largest wingspans in the world
  • Valuable scavenger of the savanna
  • Very adaptable, even near humans
  • Large, unthreatened populations

Cons

  • Inelegant, grim appearance
  • Depends on the availability of carrion and waste
  • May concentrate at urban landfills

FAQ

Why does the marabou have a bald head?
The head and neck almost free of feathers are an adaptation to the scavenging life: they stay cleaner when the bird thrusts its head into carcasses to feed. It is the same reason why many vultures have a bare head.
How large is the marabou's wingspan?
It is among the largest of any land bird: on average it exceeds 2.5 metres, and in some exceptional individuals it can approach 3 metres and more. Thanks to these great wings, it glides for long periods by exploiting rising air currents.
What does the marabou eat?
It is above all a scavenger: it feeds mainly on carrion and animal remains, often alongside vultures. But it is opportunistic and also eats fish, frogs, insects, small animals and food waste near towns.
Is it a useful bird?
Yes, despite its appearance it plays a valuable ecological role: by clearing the environment of carcasses and waste, it limits the spread of disease. It is an important presence in the ecosystems of the African savanna.
