Way of life

Marabou storks are sedentary, although some of those living far north or south can migrate towards central Africa in order to reproduce. They form fairly large colonies and are often associated with pelicans. The male chooses a site, defends it and waits for a female near the basic nest. The nest is built in a tree at a height of between 10 and 30 metres and is located near a water source, it is often renovated from one year to the next. Both parents take it in turns to incubate and they regurgitate food for their young.

Distinguishing features

Not as elegant as its cousin the stork, the marabou stork regularly joins forces with vultures to remove carcasses. Its featherless head and neck allow it to rummage around carcasses without getting dirty! This scavenger is often seen on the lookout for even the tiniest bit of rubbish near villages, landfills or abattoirs and, on occasion, it hunts small prey.

Because of its weight, the marabou stork flies by gliding, which conserves energy and uses warm air currents to help it rise up in the air. Like herons, it flies with its legs outstretched and its neck bent. In adults, the long gular sac, which swells to demonstrate dominance, is also used for thermoregulation.

Anecdote

Marabou storks are victims of environmental upheavals and pesticides, however, their populations are dense enough to ensure that they are not endangered. They are hunted locally for traditional medicine.
