14 Facts About the Marabou Stork, Africa’s “Undertaker Bird”

The marabou stork is a massive bird that roams the African savannah, cutting an imposing figure with its bald head and enormous beak. Often called the “undertaker bird” due to its appearance, this scavenger plays a crucial part in Africa’s ecosystems. While it might not win any beauty contests, the marabou stork is a fascinating creature with some truly remarkable adaptations. From its unusual eating habits to its impressive size, this bird never fails to capture the imagination of wildlife enthusiasts. Let’s explore some intriguing facts about this unique avian species. Found across sub-Saharan Africa, these birds are particularly common in the wetlands and grasslands of East Africa.

Bigger Than You Might Think

The marabou stork is one of the largest flying birds in the world. It can stand up to 1.5 metres (5 feet) tall and have a wingspan of up to 3.7 metres (12 feet). That’s wider than many cars are long! Adult marabous can weigh up to 9 kilograms (20 pounds), making them one of the heaviest flying birds as well.

A Face Only a Mother Could Love

With its bare head, long neck wattle, and huge bill, the marabou stork isn’t exactly pretty. Its appearance has earned it nicknames like “nightmare bird” and “philosopher bird”. The lack of feathers on its head helps keep it clean when feeding on carcasses. The bird’s massive bill, which can reach lengths of up to 34.6 centimetres (13.6 inches), is perfectly adapted for tearing into tough hides.

Nature’s Cleanup Crew

Marabou storks are scavengers, feeding mainly on carrion (dead animals). They play a vital role in their habitats by cleaning up decaying flesh that could spread disease. Their strong beaks can tear through tough hides with ease. This scavenging behaviour also helps to recycle nutrients back into the ecosystem, supporting the growth of plants and other organisms.

Stork or Vulture?

While it’s called a stork, the marabou shares many characteristics with vultures. Both have featherless heads and scavenging habits. In fact, marabous often feed alongside vultures at carcasses. Like vultures, marabou storks have excellent eyesight, which helps them spot potential food sources from great distances.

Silent but Deadly

Unlike many birds, marabou storks don’t have a syrinx (voice box). They can’t sing or call, but they can make loud clattering noises with their bills. They also grunt and hiss when threatened. During courtship, males produce a guttural croaking sound by inflating their throat sacs.

Garbage Gourmets

In urban areas, marabou storks have adapted to human presence. They’re often seen foraging in rubbish dumps and hanging around fish markets for scraps. This adaptability has helped their populations in some areas. Their ability to thrive in human-altered landscapes has led to increasing numbers in some cities, where they’ve become a common sight on rooftops and in parks.

Masters of the Air

Despite their ungainly appearance on the ground, marabou storks are excellent flyers. They can soar for hours on thermal currents, travelling long distances with minimal effort. Their huge wings make them expert gliders. In flight, they can reach speeds of up to 50 kilometres (31 miles) per hour.

Nesting in Numbers

Marabou storks often nest in large colonies, sometimes with hundreds of pairs in a single area. They prefer tall trees near water sources and return to the same nesting sites year after year. Their nests are large platforms of sticks, which can measure up to 1.5 metres (5 feet) across.

Not Just Scavengers

While they’re known for eating carrion, marabou storks are opportunistic feeders. They also eat fish, reptiles, insects, and even smaller birds. In some areas, they’ve been observed hunting flamingos! Their diverse diet helps them survive in a variety of habitats and adapt to changing food availability.

Built-in Air Conditioning

The marabou stork has a unique way of keeping cool. It can defecate on its own legs, and as the liquid evaporates, it helps lower the bird’s body temperature. It’s not pretty, but it’s effective! This behaviour, known as urohydrosis, is also seen in some other large birds like vultures.

Long-lived Birds

Marabou storks can live for a long time in the wild, with some individuals reaching 25 years old. In captivity, they’ve been known to live even longer, up to 41 years. This longevity is quite remarkable for a bird of its size and contributes to its importance in its ecosystem.

Cultural Significance

In some African cultures, the marabou stork is seen as a symbol of wisdom due to its contemplative stance. However, in others, it’s associated with death because of its scavenging habits. In Uganda, the marabou stork is nicknamed “the politician” due to its puffed-up appearance and scavenging nature.

Feathers for Fashion

Sadly, marabou storks were once hunted for their soft under-feathers, which were used in the fashion industry. While this practice has largely stopped, it contributed to population declines in the past. These soft, fluffy feathers were often used to trim hats, boas, and other clothing items in the early 20th century.

Conservation Status

Despite past threats, marabou stork populations are currently stable. They’re listed as “Least Concern” by the IUCN. However, habitat loss and pollution still pose challenges to these unique birds. Conservation efforts now focus on protecting their wetland habitats and reducing human-wildlife conflicts in urban areas.

15 Animals That Eat Hornets

Nature never fails to amaze me. Who would’ve thought so many creatures would prey on hornets? Their painful stings and fierce and aggressive behaviour make them seem like a pretty unappetizing meal to me. While hornets might seem like formidable insects that few creatures would dare to tangle with, they actually have quite a few natural enemies. From nimble birds to crafty mammals, plenty of other creatures make meals out of these stinging insects.
