The marabou stork (Leptoptilos crumenifer) is a large wading bird in the stork family Ciconiidae native to sub-Saharan Africa. It breeds in both wet and arid habitats, often near human habitation, especially landfill sites. It is sometimes called the "undertaker bird" due to its shape from behind: cloak-like wings and back, skinny white legs, and sometimes a large white mass of "hair". [2] [ better source needed ]

Taxonomy

The marabou stork was formally described in 1831 by the French naturalist René Lesson. He placed it in the stork genus Ciconia and coined the binomial name Ciconia crumenifera. He specified that locality as Senegal. [3] The species is now placed with the lesser adjutant and the greater adjutant in the genus Leptoptilos that Lesson had introduced at the same time he described the marabou stork. [4] The species is monotypic: no subspecies are recognised. [4]

The common name marabou is thought to be derived from the Arabic word murābit meaning quiet or hermit-like. [5] The species was originally described as Ciconia crumenifera. When the species was moved into the genus Leptoptilos, the ending was modified to crumeniferus and this was used by many authors until it was noted that the correct masculine ending to match the genus is crumenifer. [6]

Description

The marabou stork is a massive bird: large specimens are thought to reach a height of 152 centimetres (4.99 feet) and a weight of 9 kg (20 lb). [7] [8] A wingspan of 3.7 m (12 ft) was accepted by Fisher and Peterson, who ranked the species as having the largest wing-spread of any living bird. Even higher measurements of up to 4.06 m (13.3 ft) have been reported, although no measurement over 3.20 m (10.5 ft) has been verified.[ citation needed ] It is often credited with the largest spread of any landbird, to rival the Andean condor; more typically, however, these storks measure 225–287 cm (7–9 ft) across the wings, which is about a foot less than the average Andean condor wingspan and nearly two feet less than the average of the largest albatrosses and pelicans. Typical weight is 4.5–8 kg (9.9–17.6 lb), unusually as low as 4 kg (8.8 lb), and length (from bill to tail) is 120 to 130 cm (47 to 51 in). Females are smaller than males. Bill length can range from 26.4 to 35 cm (10.4 to 13.8 in). [9] [10] [11] Unlike most storks, the three Leptoptilos species fly with the neck retracted like a heron.

The marabou is unmistakable due to its size, bare head and neck, black back, and white underparts. It has a huge bill, a pink gular sac at its throat (crumenifer(us) means "carrier of a pouch for money"), a neck ruff, and white legs and black wings. The sexes are alike, but the young bird is browner and has a smaller bill. Full maturity is not reached for up to four years.

Behavior and ecology

Like most storks, the marabou is gregarious and a colonial breeder. In the African dry season (when food is more readily available as the pools shrink), it builds a tree nest in which two or three eggs are laid. It is known to be quite ill-tempered.

It also resembles other storks in that it is not very vocal, but indulges in bill-rattling courtship displays. The throat sac is also used to make various noises at that time.

Breeding

The marabou stork breeds in Africa south of the Sahara. In East Africa, the birds interact with humans and breed in urban areas. In southern African countries, the birds breed mainly in less populated areas. [12] The marabou stork breeds in colonies, starting during the dry season. The female lays two to three eggs in a small nest made of sticks; eggs hatch after an incubation period of 30 days. Their young reach sexual maturity at 4 years of age. Lifespan is 43 years in captivity and 25 years in wild. [13]

The marabou stork is a frequent scavenger, and the naked head and long neck are adaptations to this livelihood, as it is with the vultures with which the stork often feeds. In both cases, a feathered head would become rapidly clotted with blood and other substances when the bird's head was inside a large corpse, and the bare head is easier to keep clean.[ citation needed ]

This large and powerful bird eats mainly carrion, scraps, and faeces but will opportunistically eat almost any animal matter it can swallow. It occasionally eats other birds including Quelea nestlings, pigeons, doves, pelican and cormorant chicks, and even flamingos. During the breeding season, adults scale back on carrion and take mostly small, live prey since nestlings need this kind of food to survive. Common prey at this time may consist of fish, frogs, insects, eggs, small mammals and reptiles such as crocodile hatchlings and eggs, [9] and lizards and snakes. [14] Though known to eat putrid and seemingly inedible foods, these storks may sometimes wash food in water to remove soil. [15]

When feeding on carrion, marabou frequently follow vultures, which are better equipped with hooked bills for tearing through carrion meat and may wait for the vultures to cast aside a piece, steal a piece of meat directly from the vulture or wait until the vultures are done. [9] As with vultures, marabou storks perform an important natural function by cleaning areas via their ingestion of carrion and waste.

Increasingly, marabous have become dependent on human garbage and hundreds of the huge birds can be found around African dumps or waiting for a hand out in urban areas. Marabous eating human garbage have been seen to devour virtually anything that they can swallow, including shoes and pieces of metal. Marabous conditioned to eating from human sources have been known to lash out when refused food. [9]

Threats

Fully grown marabou storks have few natural enemies, and have high annual survival rate, [16] though lions have reportedly preyed on some individuals in ambush. [17] A number of endoparasites have been identified in wild marabous including Cheilospirura , Echinura and Acuaria nematodes, Amoebotaenia sphenoides (Cestoda) and Dicrocoelium hospes (Trematoda). [18]

Human uses

Storks are large, long-legged, long-necked wading birds with long, stout bills. They belong to the family called Ciconiidae, and make up the order Ciconiiformes. Ciconiiformes previously included a number of other families, such as herons and ibises, but those families have been moved to other orders.

<span class="mw-page-title-main">Shoebill</span> Species of bird

The shoebill, also known as the whalebill, whale-headed stork, and shoe-billed stork is a large long-legged wading bird. It derives its name from its enormous shoe-shaped bill. It has a somewhat stork-like overall form and has previously been classified with the storks in the order Ciconiiformes based on this morphology. However, genetic evidence places it with pelicans and herons in the Pelecaniformes. The adult is mainly grey while the juveniles are more brown. It lives in tropical East Africa in large swamps from South Sudan to Zambia.

<span class="mw-page-title-main">White stork</span> Species of bird

The white stork is a large bird in the stork family, Ciconiidae. Its plumage is mainly white, with black on the bird's wings. Adults have long red legs and long pointed red beaks, and measure on average 100–115 cm (39–45 in) from beak tip to end of tail, with a 155–215 cm (61–85 in) wingspan. The two subspecies, which differ slightly in size, breed in Europe, northwestern Africa, southwestern Asia and southern Africa. The white stork is a long-distance migrant, wintering in Africa from tropical Sub-Saharan Africa to as far south as South Africa, or on the Indian subcontinent. When migrating between Europe and Africa, it avoids crossing the Mediterranean Sea and detours via the Levant in the east or the Strait of Gibraltar in the west, because the air thermals on which it depends for soaring do not form over water.

<span class="mw-page-title-main">Black stork</span> Large migratory bird in the family Ciconiidae

The black stork is a large bird in the stork family Ciconiidae. It was first described by Carl Linnaeus in the 10th edition of his Systema Naturae. Measuring on average 95 to 100 cm from beak tip to end of tail with a 145-to-155 cm (57-to-61 in) wingspan, the adult black stork has mainly black plumage, with white underparts, long red legs and a long pointed red beak. A widespread but uncommon species, it breeds in scattered locations across Europe, and east across the Palearctic to the Pacific Ocean. It is a long-distance migrant, with European populations wintering in tropical Sub-Saharan Africa, and Asian populations in the Indian subcontinent. When migrating between Europe and Africa, it avoids crossing broad expanses of the Mediterranean Sea and detours via the Levant in the east, the Strait of Sicily in the center, or the Strait of Gibraltar in the west. An isolated, non-migratory, population occurs in Southern Africa.

<span class="mw-page-title-main">Asian woolly-necked stork</span> Species of bird

The Asian woolly-necked stork or Asian woollyneck is a species of large wading bird in the stork family Ciconiidae. It breeds singly, or in small loose colonies. It is distributed in a wide variety of habitats including marshes in forests, agricultural areas, and freshwater wetlands across Asia.

<span class="mw-page-title-main">Lesser adjutant</span> Species of bird

The lesser adjutant is a large wading bird in the stork family Ciconiidae. Like other members of its genus, it has a bare neck and head. It is however more closely associated with wetland habitats where it is solitary and is less likely to scavenge than the related greater adjutant. It is a widespread species found from India through Southeast Asia to Java.

<i>Leptoptilos</i> Genus of birds

Leptoptilos is a genus of very large tropical storks, commonly known as adjutants. The name means thin (lepto) feather (ptilos). Two species are resident breeders in southern Asia, and the marabou stork is found in Sub-Saharan Africa.

<span class="mw-page-title-main">Greater adjutant</span> Species of bird

The greater adjutant is a member of the stork family, Ciconiidae. Its genus includes the lesser adjutant of Asia and the marabou stork of Africa. Once found widely across southern Asia and mainland southeast Asia, the greater adjutant is now restricted to a much smaller range with only three breeding populations; two in India, with the largest colony in Assam, a smaller one around Bhagalpur; and another breeding population in Cambodia. They disperse widely after the breeding season. This large stork has a massive wedge-shaped bill, a bare head and a distinctive neck pouch. During the day, it soars in thermals along with vultures with whom it shares the habit of scavenging. They feed mainly on carrion and offal; however, they are opportunistic and will sometimes prey on vertebrates. The English name is derived from their stiff "military" gait when walking on the ground. Large numbers once lived in Asia, but they have declined to the point of endangerment. The total population in 2008 was estimated at around a thousand individuals. In the 19th century, they were especially common in the city of Calcutta, where they were referred to as the "Calcutta adjutant" and included in the coat of arms for the city. Known locally as hargila and considered to be unclean birds, they were largely left undisturbed but sometimes hunted for the use of their meat in folk medicine. Valued as scavengers, they were once depicted in the logo of the Calcutta Municipal Corporation.

<span class="mw-page-title-main">Storm's stork</span> Species of bird

Storm's stork is a medium-sized stork species that occurs primarily in lowland tropical forests of Indonesia, Malaysia and southern Thailand. It is considered to be the rarest of all storks, and is estimated to number less than 500 wild individuals throughout its geographic range. The population has long been in decline and the primary cause is widely considered to be deforestation of its native habitat.

<span class="mw-page-title-main">African openbill</span> Species of stork

The African openbill is a species of stork from the family Ciconiidae. It is widely distributed in Sub-Saharan Africa and western regions of Madagascar. This species is considered common to locally abundant across its range, although it has a patchy distribution. Some experts consider there to be two sub-species, A. l. lamelligerus distributed on the continent and A. l. madagascariensis living on the island of Madagascar. Scientists distinguish between the two sub-species due to the more pronounced longitudinal ridges on the bills of adult A. l. madagascariensis. The Asian openbill found in Asia is the African openbill’s closest relative. The two species share the same notably large bill of a peculiar shape that gives them their name.

<span class="mw-page-title-main">Maguari stork</span> Species of bird

The maguari stork is a large species of stork that inhabits seasonal wetlands over much of South America, and is very similar in appearance to the white stork; albeit slightly larger.

<i>Leptoptilos robustus</i> Extinct species of stork

Leptoptilos robustus is an extinct species of large-bodied stork belonging to the genus Leptoptilos that lived on the island of Flores in Indonesia during the Pleistocene epoch. It stood at about 1.8 metres (5.9 ft) tall and weighed up to an estimated 16 kilograms (35 lb). The majority of the discoveries are concentrated in Liang Bua cave located slightly north of Ruteng in the East Nusa Tenggara province.

Leptoptilos falconeri is an extinct species of large-bodied stork that existed during the Pliocene, having persisted until just over 2.58 million years ago. Although not the oldest fossil species of the genus Leptoptilos it was the first fossil species of the genus to be described. Furthermore, it was the largest known species of stork ever and amongst the tallest and heaviest flying birds known to have existed, having reached at least 2 m in height.
