Pelicans are a genus of large water birds that make up the family Pelecanidae. They are characterised by a long beak and a large throat pouch used for catching prey and draining water from the scooped-up contents before swallowing. They have predominantly pale plumage, the exceptions being the brown and Peruvian pelicans. The bills, pouches, and bare facial skin of all species become brightly coloured before the breeding season. The eight living pelican species have a patchy global distribution, ranging latitudinally from the tropics to the temperate zone, though they are absent from interior South America and from polar regions and the open ocean.

A genus is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.

Water bird Bird that lives on or around water

The term water bird, waterbird or aquatic bird is used to refer to birds that live on or around water. Some definitions apply the term especially to birds in freshwater habitats, though others make no distinction from birds that inhabit marine environments. In addition, some water birds are more terrestrial or aquatic than others, and their adaptations will vary depending on their environment. These adaptations include webbed feet, bills and legs adapted to feed in water, and the ability to dive from the surface or the air to catch prey in water.

Family is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy; it is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as being the "walnut family".

Long thought to be related to frigatebirds, cormorants, tropicbirds, and gannets and boobies, pelicans instead are now known to be most closely related to the shoebill and hamerkop, and are placed in the order Pelecaniformes. Ibises, spoonbills, herons, and bitterns have been classified in the same order. Fossil evidence of pelicans dates back at least 30 million years to the remains of a beak very similar to that of modern species recovered from Oligocene strata in France. They are thought to have evolved in the Old World and spread into the Americas; this is reflected in the relationships within the genus as the eight species divide into Old World and New World lineages.

Frigatebird A family of seabirds found across tropical and subtropical oceans

Frigatebirds are a family of seabirds called Fregatidae which are found across all tropical and subtropical oceans. The five extant species are classified in a single genus, Fregata. All have predominantly black plumage, long, deeply forked tails and long hooked bills. Females have white underbellies and males have a distinctive red gular pouch, which they inflate during the breeding season to attract females. Their wings are long and pointed and can span up to 2.3 metres (7.5 ft), the largest wing area to body weight ratio of any bird.

Cormorant family of birds

Phalacrocoracidae is a family of approximately 40 species of aquatic birds commonly known as cormorants and shags. Several different classifications of the family have been proposed recently, and the number of genera is disputed. The great cormorant and the common shag are the only two species of the family commonly encountered on the British Isles, and "cormorant" and "shag" appellations have been later assigned to different species in the family somewhat haphazardly.

Tropicbird Family of birds

Tropicbirds are a family, Phaethontidae, of tropical pelagic seabirds. They are the sole living representatives of the order Phaethontiformes. For many years they were considered part of the Pelecaniformes, but genetics indicates they are most closely related to the Eurypygiformes. There are three species in one genus, Phaethon. The scientific names are derived from Ancient Greek phaethon, "sun". They have predominantly white plumage with elongated tail feathers and small feeble legs and feet.

Pelicans frequent inland and coastal waters, where they feed principally on fish, catching them at or near the water surface. They are gregarious birds, travelling in flocks, hunting cooperatively, and breeding colonially. Four white-plumaged species tend to nest on the ground, and four brown or grey-plumaged species nest mainly in trees. The relationship between pelicans and people has often been contentious. The birds have been persecuted because of their perceived competition with commercial and recreational fishing. Their populations have fallen through habitat destruction, disturbance, and environmental pollution, and three species are of conservation concern. They also have a long history of cultural significance in mythology, and in Christian and heraldic iconography.

Bird colony large congregation of birds at a particular location

A bird colony is a large congregation of individuals of one or more species of bird that nest or roost in proximity at a particular location. Many kinds of birds are known to congregate in groups of varying size; a congregation of nesting birds is called a breeding colony. Colonial nesting birds include seabirds such as auks and albatrosses; wetland species such as herons; and a few passerines such as weaverbirds, certain blackbirds, and some swallows. A group of birds congregating for rest is called a communal roost. Evidence of colonial nesting has been found in non-neornithine birds (Enantiornithes), in sediments from the Late Cretaceous (Maastrichtian) of Romania.

Heraldry Profession, study, or art of creating, granting, and blazoning arms and ruling on questions of rank or protocol

Heraldry is a broad term, encompassing the design, display, and study of armorial bearings, as well as related disciplines, such as vexillology, together with the study of ceremony, rank, and pedigree. Armory, the best-known branch of heraldry, concerns the design and transmission of the heraldic achievement. The achievement, or armorial bearings usually includes a coat of arms on an shield, helmet, and crest, together with any accompanying devices, such as supporters, badges, heraldic banners, and mottoes.

Iconography Branch of art history

Iconography, as a branch of art history, studies the identification, description, and the interpretation of the content of images: the subjects depicted, the particular compositions and details used to do so, and other elements that are distinct from artistic style. The word iconography comes from the Greek εἰκών ("image") and γράφειν.

Taxonomy and systematics

Etymology

The genus Pelecanus was first formally described by Linnaeus in 1758 in the tenth edition of his Systema Naturae'. He described the distinguishing characteristics as a straight bill hooked at the tip, linear nostrils, a bare face, and fully webbed feet. This early definition included frigatebirds, cormorants, and sulids, as well as pelicans. [1] The name comes from the Ancient Greek word pelekan (πελεκάν), [2] which is itself derived from the word pelekys (πέλεκυς) meaning "axe". [3] In classical times, the word was applied to both the pelican and the woodpecker. [4]

Carl Linnaeus Swedish botanist, physician, and zoologist

Carl Linnaeus, also known after his ennoblement as Carl von Linné, was a Swedish botanist, physician, and zoologist who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin, and his name is rendered in Latin as Carolus Linnæus.

10th edition of <i>Systema Naturae</i> Book by Carl Linnaeus

The 10th edition of Systema Naturae is a book written by Swedish naturalist Carolus Linnaeus and published in two volumes in 1758 and 1759, which marks the starting point of zoological nomenclature. In it, Linnaeus introduced binomial nomenclature for animals, something he had already done for plants in his 1753 publication of Species Plantarum.

Sulidae Family of birds

The bird family Sulidae comprises the gannets and boobies. Collectively called sulids, they are medium-large coastal seabirds that plunge-dive for fish and similar prey. The ten species in this family are often considered congeneric in older sources, placing all in the genus Sula. However, Sula and Morus (gannets) can be readily distinguished by morphological, behavioral, and DNA sequence characters. Abbott's booby (Papasula) is given its own genus as it stands apart from both in these respects. It appears to be a distinct and ancient lineage, maybe closer to the gannets than to the true boobies.

Taxonomy

The family Pelecanidae was introduced (as Pelicanea) by the French polymath Constantine Samuel Rafinesque in 1815. [5] [6] Pelicans give their name to the Pelecaniformes, an order which has a varied taxonomic history. Tropicbirds, darters, cormorants, gannets, boobies, and frigatebirds, all traditional members of the order, have since been reclassified: tropicbirds into their own order, Phaethontiformes, and the remainder into the Suliformes. In their place, herons, ibises, spoonbills, the hamerkop, and the shoebill have now been transferred into the Pelecaniformes. [7] Molecular evidence suggests that the shoebill and the hamerkop form a sister group to the pelicans, [8] though some doubt exists as to the exact relationships among the three lineages. [9]

Polymath person whose expertise spans a significant number of different subject areas

A polymath is a person whose expertise spans a significant number of subject areas, known to draw on complex bodies of knowledge to solve specific problems.

Constantine Samuel Rafinesque naturalist

Constantine Samuel Rafinesque-Schmaltz, as he is known in Europe, was a nineteenth-century polymath born near Constantinople in the Ottoman Empire and self-educated in France. He traveled as a young man in the United States, ultimately settling in Ohio in 1815, where he made notable contributions to botany, zoology, and the study of prehistoric earthworks in North America. He also contributed to the study of ancient Mesoamerican linguistics, in addition to work he had already completed in Europe.

In biological classification, the order is

  1. a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. Other well-known ranks are life, domain, kingdom, phylum, class, family, genus, and species, with order fitting in between class and family. An immediately higher rank, superorder, may be added directly above order, while suborder would be a lower rank.
  2. a taxonomic unit, a taxon, in that rank. In that case the plural is orders.

Closest living relatives

Living species

The eight living pelican species were traditionally divided into two groups, one containing four ground-nesters with mainly white adult plumage (Australian, Dalmatian, great white, and American white pelicans), and one containing four grey- or brown-plumaged species which nest preferentially either in trees (pink-backed, spot-billed and brown pelicans), or on sea rocks (Peruvian pelican). The largely marine brown and Peruvian pelicans, formerly considered conspecific, [11] are sometimes separated from the others by placement in the subgenus Leptopelicanus [12] but in fact species with both sorts of appearance and nesting behavior are found in either.

Australian pelican species of bird

The Australian pelican is a large waterbird in the family Pelecanidae, widespread on the inland and coastal waters of Australia and New Guinea, also in Fiji, parts of Indonesia and as a vagrant in New Zealand. It is a predominantly white bird with black wings and a pink bill. It has been recorded as having the longest bill of any living bird. It mainly eats fish, but will also consume birds and scavenges for scraps if the opportunity arrises.

Dalmatian pelican species of bird

The Dalmatian pelican is the most massive member of the pelican family, and perhaps the world's largest freshwater bird, although rivaled in weight and length by the largest swans. They are elegant soaring birds, with wingspans that rival that of the great albatrosses, and their flocks fly in graceful synchrony. It is a short to medium distance migrant between breeding and overwintering areas. No subspecies are known to exist over its wide range, but based on size differences, a Pleistocene paleosubspecies, P. c. palaeocrispus, has been described from fossils recovered at Binagady, Azerbaijan.

Great white pelican species of bird

The great white pelican also known as the eastern white pelican, rosy pelican or white pelican is a bird in the pelican family. It breeds from southeastern Europe through Asia and Africa, in swamps and shallow lakes.

DNA sequencing of both mitochondrial and nuclear genes yielded quite different relationships; the three New World pelicans formed one lineage, with the American white pelican sister to the two brown pelicans, and the five Old World species the other. The Dalmatian, pink-backed, and spot-billed were all closely related to one another, while the Australian white pelican was their next-closest relative. The great white pelican also belonged to this lineage, but was the first to diverge from the common ancestor of the other four species. This finding suggests that pelicans evolved in the Old World and spread into the Americas, and that preference for tree- or ground-nesting is more related to size than genetics. [10]

Fossil record

The fossil record shows that the pelican lineage has existed for at least 30 million years; the oldest known pelican fossil was found in Early Oligocene deposits at the Luberon in southeastern France, and is remarkably similar to modern forms. [35] Its beak is almost complete and is morphologically identical to that of present-day pelicans, showing that this advanced feeding apparatus was already in existence at the time. [35] An Early Miocene fossil has been named Miopelecanus gracilis on the basis of certain features originally considered unique, but later thought to lie within the range of interspecific variation in Pelecanus. [35] The Late Eocene Protopelicanus may be a pelecaniform or suliform – or a similar aquatic bird such as a pseudotooth (Pelagornithidae). [36] The supposed Miocene pelican Liptornis from Patagonia is a nomen dubium (of doubtful validity), being based on fragments providing insufficient evidence to support a valid description. [37]

Fossil finds from North America have been meagre compared with Europe, which has a richer fossil record. [38] Several Pelecanus species have been described from fossil material, including: [39]

Pelicans are very large birds with very long bills characterised by a downcurved hook at the end of the upper mandible, and the attachment of a huge gular pouch to the lower. The slender rami of the lower bill and the flexible tongue muscles form the pouch into a basket for catching fish, and sometimes rainwater, [12] though not to hinder the swallowing of large fish, the tongue itself is tiny. [45] They have a long neck and short stout legs with large, fully webbed feet. Although they are among the heaviest of flying birds, [46] they are relatively light for their apparent bulk because of air pockets in the skeleton and beneath the skin, enabling them to float high in the water. [12] The tail is short and square. The wings are long and broad, suitably shaped for soaring and gliding flight, and have the unusually large number of 30 to 35 secondary flight feathers. [47]

Males are generally larger than females and have longer bills. [12] The smallest species is the brown pelican, small individuals of which can be no more than 2.75 kg (6.1 lb) and 1.06 m (3.5 ft) long, with a wingspan of as little as 1.83 m (6.0 ft). The largest is believed to be the Dalmatian, at up to 15 kg (33 lb) and 1.83 m (6.0 ft) in length, with a maximum wingspan of 3 m (9.8 ft). The Australian pelican's bill may grow up to 0.5 m (1.6 ft) long in large males, [48] the longest of any bird. [11]

Pelicans have mainly light-coloured plumage, the exceptions being the brown and Peruvian pelicans. [49] The bills, pouches, and bare facial skin of all species become brighter before breeding season commences. [50] The throat pouch of the Californian subspecies of the brown pelican turns bright red, and fades to yellow after the eggs are laid, while the throat pouch of the Peruvian pelican turns blue. The American white pelican grows a prominent knob on its bill that is shed once females have laid eggs. [51] The plumage of immature pelicans is darker than that of adults. [49] Newly hatched chicks are naked and pink, darkening to grey or black after 4 to 14 days, then developing a covering of white or grey down. [52]

Air sacs

Anatomical dissections of two brown pelicans in 1939 showed that pelicans have a network of subcutaneous air sacs under their skin situated across the ventral surface including the throat, breast, and undersides of the wings, as well as having air sacs in their bones. [53] The air sacs are connected to the airways of the respiratory system, and the pelican can keep its air sacs inflated by closing its glottis, but how air sacs are inflated is not clear. [53] The air sacs serve to keep the pelican remarkably buoyant in the water [54] and may also cushion the impact of the pelican's body on the water surface when they dive from flight into water to catch fish. [53] Superficial air sacs may also help to round body contours (especially over the abdomen, where surface protuberances may be caused by viscera changing size and position) to enable the overlying feathers to form more effective heat insulation and also to enable feathers to be held in position for good aerodynamics. [53]

Distribution and habitat

Modern pelicans are found on all continents except Antarctica. They primarily inhabit warm regions, although breeding ranges extend to latitudes of 45° South (Australian pelicans in Tasmania) and 60° North (American white pelicans in western Canada). [11] Birds of inland and coastal waters, they are absent from polar regions, the deep ocean, oceanic islands (except the Galapagos), and inland South America, as well as from the eastern coast of South America from the mouth of the Amazon River southwards. [12] Subfossil bones have been recovered from as far south as New Zealand's South Island, [55] although their scarcity and isolated occurrence suggests that these remains may have merely been vagrants from Australia (much as is the case today). [56]

Behaviour and ecology

Pelicans swim well with their strong legs and their webbed feet. They rub the backs of their heads on their preen glands to pick up an oily secretion, which they transfer to their plumage to waterproof it. [11] Holding their wings only loosely against their bodies, pelicans float with relatively little of their bodies below the water surface. [28] They dissipate excess heat by gular flutter – rippling the skin of the throat and pouch with the bill open to promote evaporative cooling. [12] They roost and loaf communally on beaches, sandbanks, and in shallow water. [12]

A fibrous layer deep in the breast muscles can hold the wings rigidly horizontal for gliding and soaring. Thus, they use thermals for soaring to heights of 3000 m (10,000 ft) or more, [57] combined both with gliding and with flapping flight in V formation, to commute distances up to 150 km (93 mi) to feeding areas. [11] Pelicans also fly low (or "skim") over stretches of water, using a phenomenon known as ground effect to reduce drag and increase lift. As the air flows between the wings and the water surface, it is compressed to a higher density and exerts a stronger upward force against the bird above. [58] Hence, substantial energy is saved while flying. [59]

Adult pelicans rely on visual displays and behaviour to communicate, [60] particularly using their wings and bills. Agonistic behaviour consists of thrusting and snapping at opponents with their bills, or lifting and waving their wings in a threatening manner. [61] Adult pelicans grunt when at the colony, but are generally silent elsewhere or outside breeding season. [28] [62] [63] [64] Conversely, colonies are noisy, as chicks vocalise extensively. [60]

A nesting colony of Australian pelicans on the coast of New South Wales, Australia: This species nests on the ground.

Pelicans are gregarious and nest colonially. Pairs are monogamous for a single season, but the pair bond extends only to the nesting area; mates are independent away from the nest. The ground-nesting (white) species have a complex communal courtship involving a group of males chasing a single female in the air, on land, or in the water while pointing, gaping, and thrusting their bills at each other. They can finish the process in a day. The tree-nesting species have a simpler process in which perched males advertise for females. [11] The location of the breeding colony is constrained by the availability of an ample supply of fish to eat, although pelicans can use thermals to soar and commute for hundreds of kilometres daily to fetch food. [50]

The Australian pelican has two reproductive strategies depending on the local degree of environmental predictability. Colonies of tens or hundreds, rarely thousands, of birds breed regularly on small coastal and subcoastal islands where food is seasonally or permanently available. In arid inland Australia, especially in the endorheic Lake Eyre basin, pelicans breed opportunistically in very large numbers of up to 50,000 pairs, when irregular major floods, which may be many years apart, fill ephemeral salt lakes and provide large amounts of food for several months before drying out again. [57]

In all species, copulation takes place at the nest site; it begins shortly after pairing and continues for 3–10 days before egg-laying. The male brings the nesting material, in ground-nesting species (which may not build a nest) sometimes in the pouch, and in tree-nesting species crosswise in the bill. The female then heaps the material up to form a simple structure. [11]

The eggs are oval, white, and coarsely textured. [12] All species normally lay at least two eggs; the usual clutch size is one to three, rarely up to six. [12] Both sexes incubate with the eggs on top of or below the feet; they may display when changing shifts. Incubation takes 30–36 days; [12] hatching success for undisturbed pairs can be as high as 95%, but because of sibling competition or siblicide, in the wild, usually all but one nestling dies within the first few weeks (later in the pink-backed and spot-billed species). Both parents feed their young. Small chicks are fed by regurgitation; after about a week, they are able to put their heads into their parents' pouches and feed themselves. [52] Sometimes before, but especially after being fed the pelican chick may seem to "throw a tantrum" by loudly vocalizing and dragging itself around in a circle by one wing and leg, striking its head on the ground or anything nearby and the tantrums sometimes end in what looks like a seizure that results in the chick falling briefly unconscious; the reason is not clearly known, but a common belief is that it is to draw attention to itself and away from any siblings who are waiting to be fed. [11]

Parents of ground-nesting species sometimes drag older young around roughly by the head before feeding them. From about 25 days old, [12] the young of these species gather in "pods" or "crèches" of up to 100 birds in which parents recognise and feed only their own offspring. By 6–8 weeks they wander around, occasionally swimming, and may practise communal feeding. [11] Young of all species fledge 10–12 weeks after hatching. They may remain with their parents afterwards, but are now seldom or never fed. They are mature at three or four years old. [12] Overall breeding success is highly variable. [11] Pelicans live for 15 to 25 years in the wild, although one reached an age of 54 years in captivity. [50]

Feeding

The diet of pelicans usually consists of fish, [50] but occasionally amphibians, turtles, crustaceans, insects, birds, and mammals are also eaten. [65] [66] [67] The size of the preferred prey fish varies depending on pelican species and location. For example, in Africa, the pink-backed pelican generally takes fish ranging in size from fry up to 400 g (0.9 lb) and the great white pelican prefers somewhat larger fish, up to 600 g (1.3 lb), but in Europe, the latter species has been recorded taking fish up to 1,850 g (4.1 lb). [67] In deep water, white pelicans often fish alone. Nearer the shore, several encircle schools of small fish or form a line to drive them into the shallows, beating their wings on the water surface and then scooping up the prey. [68] Although all pelican species may feed in groups or alone, the Dalmantian, pink-backed, and spot-billed pelicans are the only ones to prefer solitary feeding. When fishing in groups, all pelican species have been known to work together to catch their prey, and Dalmantian pelicans may even cooperate with great cormorants. [67] They catch multiple small fish by expanding the throat pouch, which must be drained above the water surface before swallowing. This operation takes up to a minute, during which time other seabirds may steal the fish.

Brown pelicans diving into the sea to catch fish in Jamaica

Large fish are caught with the bill-tip, then tossed up in the air to be caught and slid into the gullet head-first. A gull will sometimes stand on the pelican's head, peck it to distraction, and grab a fish from the open bill. [69] Pelicans in their turn sometimes snatch prey from other waterbirds. [11]

The brown pelican usually plunge-dives head-first for its prey, from a height as great as 10–20 m (33–66 ft), especially for anchovies and menhaden. [70] [68] [67] The only other pelican to feed using a similar technique is the Peruvian pelican, but its dives are typically from a lower height than the brown pelican. [71] The Australian and American white pelicans may feed by low plunge-dives landing feet-first and then scooping up the prey with the beak, but they—as well as the remaining pelican species—primarily feed while swimming on the water. [67] Aquatic prey is most commonly taken at or near the water surface. [49] Although principally a fish eater, the Australian pelican is also an eclectic and opportunistic scavenger and carnivore that forages in landfill sites, as well as taking carrion [72] and "anything from insects and small crustaceans to ducks and small dogs". [72] Food is not stored in a pelican's throat pouch, contrary to popular folklore. [50]

Great white pelicans have been observed swallowing city pigeons in St. James's Park in London. [66] Spokeswoman for the Royal Parks Louise Wood opined that feeding on other birds is more likely with captive pelicans that live in a semiurban environment and are in constant close contact with humans. [66] However, in southern Africa, eggs and chicks of the Cape cormorant are an important food source for great white pelicans. [67] Several other bird species have been recorded in the diet of this pelican in South Africa, including Cape gannet chicks on Malgas Island [73] as well as crowned cormorants, kelp gulls, greater crested terns, and African penguins on Dassen Island and elsewhere. [74] The Australian pelican, which is particularly willing to take a wide range of prey items, has been recorded feeding on young Australian white ibis, and young and adult grey teals and silver gulls. [67] [75] Brown pelicans have been reported preying on young common murres in California and the eggs and nestlings of cattle egrets and nestling great egrets in Baja California, Mexico. [76] Peruvian pelicans in Chile have been recorded feeding on nestlings of imperial shags, juvenile Peruvian diving petrels, and grey gulls. [77] [78] Cannibalism of chicks of their own species is known from the Australian, brown, and Peruvian pelicans. [75] [76] [78]

Status and conservation

Populations

Globally, pelican populations are adversely affected by these main factors: declining supplies of fish through overfishing or water pollution, destruction of habitat, direct effects of human activity such as disturbance at nesting colonies, hunting and culling, entanglement in fishing lines and hooks, and the presence of pollutants such as DDT and endrin. Most species' populations are more or less stable, although three are classified by the IUCN as being at risk. All species breed readily in zoos, which is potentially useful for conservation management. [79]

The combined population of brown and Peruvian pelicans is estimated at 650,000 birds, with around 250,000 in the United States and Caribbean, and 400,000 in Peru. [lower-alpha 1] The National Audubon Society estimates the global population of the brown pelican at 300,000. [81] Numbers of brown pelican plummeted in the 1950s and 1960s, largely as a consequence of environmental DDT pollution, and the species was listed as endangered in the US in 1970. With restrictions on DDT use in the US from 1972, its population has recovered, and it was delisted in 2009. [80] [82]

The Peruvian pelican is listed as near threatened because, although the population is estimated by BirdLife International to exceed 500,000 mature individuals, and is possibly increasing, it has been much higher in the past. It declined dramatically during the 1998 El Niño event and could experience similar declines in the future. Conservation needs include regular monitoring throughout the range to determine population trends, particularly after El Niño years, restricting human access to important breeding colonies, and assessing interactions with fisheries. [83]

The spot-billed pelican has an estimated population between 13,000 and 18,000 and is considered to be near threatened in the IUCN Red List of Threatened Species. Numbers declined substantially during the 20th century, one crucial factor being the eradication of the important Sittaung valley breeding colony in Burma through deforestation and the loss of feeding sites. [84] The chief threats it faces are from habitat loss and human disturbance, but populations have mostly stabilised following increased protection in India and Cambodia. [34]

The pink-backed pelican has a large population ranging over much of sub-Saharan Africa. In the absence of substantial threats or evidence of declines across its range, its conservation status is assessed as being of least concern. Regional threats include the drainage of wetlands and increasing disturbance in southern Africa. The species is susceptible to bioaccumulation of toxins and the destruction of nesting trees by logging. [85]

The American white pelican has increased in numbers, [51] with its population estimated at over 157,000 birds in 2005, becoming more numerous east of the continental divide, while declining in the west. [86] However, whether its numbers have been affected by exposure to pesticides is unclear, as it has also lost habitat through wetland drainage and competition with recreational use of lakes and rivers. [51]

Great white pelicans range over a large area of Africa and southern Asia. The overall trend in numbers is uncertain, with a mix of regional populations that are increasing, declining, stable, or unknown, but no evidence has been found of rapid overall decline, and the status of the species is assessed as being of least concern. Threats include the drainage of wetlands, persecution and sport hunting, disturbance at the breeding colonies, and contamination by pesticides and heavy metals. [87]

The Dalmatian pelican has a population estimated at between 10,000 and 20,000 following massive declines in the 19th and 20th centuries. The main ongoing threats include hunting, especially in eastern Asia, disturbance, coastal development, collision with overhead power lines, and the over-exploitation of fish stocks. [88] It is listed as near threatened by the IUCN Red List of Threatened Species as the population trend is downwards, especially in Mongolia, where it is nearly extinct. However, several European colonies are increasing in size and the largest colony for the species, at the Small Prespa Lake in Greece, has reached about 1,400 breeding pairs following conservation measures. [32]

Widespread across Australia, [51] the Australian pelican has a population generally estimated at between 300,000 and 500,000 individuals. [89] Overall population numbers fluctuate widely and erratically depending on wetland conditions and breeding success across the continent. The species is assessed as being of least concern. [90]

Culling and disturbance

Pelicans have been persecuted by humans for their perceived competition for fish, despite the fact that their diet overlaps little with fish caught by people. [51] Starting in the 1880s, American white pelicans were clubbed and shot, their eggs and young were deliberately destroyed, and their feeding and nesting sites were degraded by water management schemes and wetland drainage. [51] Even in the 21st century, an increase in the population of American white pelicans in southeastern Idaho in the US was seen to threaten the recreational cutthroat trout fishery there, leading to official attempts to reduce pelican numbers through systematic harassment and culling. [91]

Great white pelicans on Dyer Island, in the Western Cape region of South Africa, were culled during the 19th century because their predation of the eggs and chicks of guano-producing seabirds was seen to threaten the livelihood of the guano collectors. [74] More recently, such predation at South African seabird colonies has impacted on the conservation of threatened seabird populations, especially crowned cormorants, Cape cormorants, and bank cormorants. This has led to suggestions that pelican numbers should be controlled at vulnerable colonies. [74]

Apart from habitat destruction and deliberate, targeted persecution, pelicans are vulnerable to disturbance at their breeding colonies by birdwatchers, photographers, and other curious visitors. Human presence alone can cause the birds to accidentally displace or destroy their eggs, leave hatchlings exposed to predators and adverse weather, or even abandon their colonies completely. [92] [93] [94]

Poisoning and pollution

DDT pollution in the environment was a major cause of decline of brown pelican populations in North America in the 1950s and 1960s. It entered the oceanic food web, contaminating and accumulating in several species, including one of the pelican’s primary food fish – the northern anchovy. Its metabolite DDE is a reproductive toxicant in pelicans and many other birds, causing eggshell thinning and weakening, and consequent breeding failure through the eggs being accidentally crushed by brooding birds. Since an effective ban on the use of DDT was implemented in the US in 1972, the eggshells of breeding brown pelicans there have thickened and their populations have largely recovered. [70] [95]

In the late 1960s, following the major decline in brown pelican numbers in Louisiana from DDT poisoning, 500 pelicans were imported from Florida to augment and re-establish the population; over 300 subsequently died in April and May 1975 from poisoning by the pesticide endrin. [96] About 14,000 pelicans, including 7500 American white pelicans, perished from botulism after eating fish from the Salton Sea in 1990. [51] In 1991, abnormal numbers of brown pelicans and Brandt's cormorants died at Santa Cruz, California, when their food fish (anchovies) were contaminated with neurotoxic domoic acid, produced by the diatom Pseudo-nitzschia . [97]

As waterbirds that feed on fish, pelicans are highly susceptible to oil spills, both directly by being oiled and by the impact on their food resources. A 2007 report to the California Fish and Game Commission estimated that during the previous 20 years, some 500–1000 brown pelicans had been affected by oil spills in California. [94] A 2011 report by the Center for Biological Diversity, a year after the April 2010 Deepwater Horizon oil spill, said that 932 brown pelicans had been collected after being affected by oiling and estimated that 10 times that number had been harmed as a result of the spill. [98]

Where pelicans interact with fishers, through either sharing the same waters or scavenging for fishing refuse, they are especially vulnerable to being hooked and entangled in both active and discarded fishing lines. Fish hooks are swallowed or catch in the skin of the pouch or webbed feet, and strong monofilament fishing line can become wound around bill, wings, or legs, resulting in crippling, starvation, and often death. Local rescue organisations have been established in North America and Australia by volunteers to treat and rehabilitate injured pelicans and other wildlife. [99] [100] [101]

Parasites and disease

As with other bird families, pelicans are susceptible to a variety of parasites. Specialist feather lice of the genus Piagetella are found in the pouches of all species of pelican, but are otherwise only known from New World and Antarctic cormorants. Avian malaria is carried by the mosquito Culex pipens, and high densities of these biting insects may force pelican colonies to be abandoned. Leeches may attach to the vent or sometimes the inside of the pouch. [102] A study of the parasites of the American white pelican found 75 different species, including tapeworms, flukes, flies, fleas, ticks, and nematodes. Many of these do little harm, but flies may be implicated in the death of nestlings, particularly if they are weak or unwell, and the soft tick Ornithodoros capensis sometimes causes adults to desert the nest. Many pelican parasites are found in other bird groups, but several lice are very host-specific. [103]

Healthy pelicans can usually cope with their lice, but sick birds may carry hundreds of individuals, which hastens their demise. The pouch louse Piagetiella peralis, which occurs in the pouch, so cannot be removed by preening, is usually not a serious problem, even when present in such numbers that it covers the whole interior of the pouch, but sometimes inflammation and bleeding may harm the host. [103] The brown pelican has a similarly extensive range of parasites. The nematodes Contracaecum multipapillatum and C. mexicanum and the trematode Ribeiroia ondatrae have caused illness and mortality in the Puerto Rican population, possibly endangering the pelican on this island. [104] In May 2012, hundreds of Peruvian pelicans were reported to have perished in Peru from a combination of starvation and roundworm infestation. [105]

The pelican (henet in Egyptian) was associated in Ancient Egypt with death and the afterlife. It was depicted in art on the walls of tombs, and figured in funerary texts, as a protective symbol against snakes. Henet was also referred to in the Pyramid Texts as the "mother of the king" and thus seen as a goddess. References in nonroyal funerary papyri show that the pelican was believed to possess the ability to prophesy safe passage in the underworld for someone who had died. [106]

Consumption of pelican, as with other seabirds, is considered not kosher as an unclean animal, and thus forbidden in Jewish dietary law. [107] [108]

An origin myth from the Murri people of Queensland, cited by Andrew Lang, describes how the Australian pelican acquired its black and white plumage. The pelican, formerly a black bird, made a canoe during a flood to save drowning people. He fell in love with a woman he thus saved, but her friends and she tricked him and escaped. The pelican consequently prepared to go to war against them by daubing himself with white clay as war paint. However, before he had finished, another pelican, on seeing such a strange piebald creature, killed him with its beak, and all such pelicans have been black and white ever since. [109]

The Moche people of ancient Peru worshipped nature. [110] They placed emphasis on animals and often depicted pelicans in their art. [111]

Alcatraz Island was given its name by the Spanish because of the large numbers of brown pelicans nesting present. The word alcatraz is itself derived from the Arabic al-caduos, a term used for a water-carrying vessel and likened to the pouch of the pelican. The English name albatross is also derived by corruption of the Spanish word. [112] [113]

In medieval Europe, the pelican was thought to be particularly attentive to her young, to the point of providing her own blood by wounding her own breast when no other food was available. As a result, the pelican came to symbolise the Passion of Jesus and the Eucharist, [114] and usurped the image of the lamb and the flag. [115] A reference to this mythical characteristic is contained for example in the hymn by Saint Thomas Aquinas, "Adoro te devote" or "Humbly We Adore Thee", where in the penultimate verse, he describes Christ as the "loving divine pelican, able to provide nourishment from his breast". [116] Elizabeth I of England adopted the symbol, portraying herself as the "mother of the Church of England". Nicholas Hilliard painted the Pelican Portrait around 1573, now owned by the Walker Art Gallery in Liverpool. [117] A pelican feeding her young is depicted in an oval panel at the bottom of the title page of the first (1611) edition of the King James Bible. [115] Such "a pelican in her piety" appears in the 1686 reredos by Grinling Gibbons in the church of St Mary Abchurch in the City of London. Earlier medieval examples of the motif appear in painted murals, for example that of circa 1350 in the parish church of Belchamp Walter, Essex. [118]

The self-sacrificial aspect of the pelican was reinforced by the widely read medieval bestiaries. The device of "a pelican in her piety" or "a pelican vulning (from Latin vulno, "to wound") herself" was used in heraldry. An older version of the myth is that the pelican used to kill its young then resurrect them with its blood, again analogous to the sacrifice of Jesus. Likewise, a folktale from India says that a pelican killed her young by rough treatment, but was then so contrite that she resurrected them with her own blood. [11]

The legends of self-wounding and the provision of blood may have arisen because of the impression a pelican sometimes gives that it is stabbing itself with its bill. In reality, it often presses this onto its chest to fully empty the pouch. Another possible derivation is the tendency of the bird to rest with its bill on its breast; the Dalmatian pelican has a blood-red pouch in the early breeding season and this may have contributed to the myth. [11]

Heraldry

The arms of the Kiszely family of Benedekfalva depict a "pelican in her piety" both in the crest and shield.

Pelicans have featured extensively in heraldry, generally using the Christian symbolism of the pelican as a caring and self-sacrificing parent. [119] Heraldic images featuring a "pelican vulning" refers to a pelican injuring herself, while a "pelican in her piety" refers to a female pelican feeding her young with her own blood. [120]

The image became linked to the medieval religious feast of Corpus Christi. The universities of Oxford and Cambridge each have colleges named for the religious festival nearest the dates of their establishment, [115] and both Corpus Christi College, Cambridge, [121] and Corpus Christi College, Oxford, feature pelicans on their coats of arms. [122]

The medical faculties of Charles University in Prague also have a pelican as their emblem. [123] The symbol of the Irish Blood Transfusion Service is a pelican, and for most of its existence the headquarters of the service was located at Pelican House in Dublin, Ireland. [124] The heraldic pelican also ended up as a pub name and image, though sometimes with the image of the ship Golden Hind . [125] Sir Francis Drake's famous ship was initially called Pelican, and adorned the British halfpenny coin. [126]

Modern usage

The great white pelican is the national bird of Romania. [127] The brown pelican is the national bird of three Caribbean countries—Saint Kitts and Nevis, Barbados, and Sint Maarten—and features on their coats of arms. [128] [129] [130] It is also the state bird of the US state of Louisiana, which is known colloquially as the Pelican State; the bird appears on the state flag and state seal. [4] It adorns the seals of Louisiana State University and Tulane University, and is the mascot of the New Orleans Pelicans NBA team, Tulane University, and the University of the West Indies. A white pelican logo is used by the Portuguese bank Montepio Geral, [131] and a pelican is depicted on the reverse of the Albanian 1 lek coin, issued in 1996. [132] The name and image were used for Pelican Books, an imprint of nonfiction books published by Penguin Books. [4] The seal of the Packer Collegiate Institute, a pelican feeding her young, has been in use since 1885. [133]

The Christian Democratic political party known as the American Solidarity Party uses the pelican as its animal symbol, alluding to its Catholic social teaching platform.

The pelican is the subject of a popular limerick originally composed by Dixon Lanier Merritt in 1910 with several variations by other authors. [134] The original version ran: [135]

A wonderful bird is the pelican,
His bill will hold more than his belican,
He can take in his beak
Food enough for a week,
But I'm damned if I see how the helican.

The nominate subspecies in its breeding plumage has a white head with a yellowish wash on the crown. The nape and neck are dark maroon–brown. The upper sides of the neck have white lines along the base of the gular pouch, and the lower fore neck has a pale yellowish patch. The male and female are similar, but the female is slightly smaller. The nonbreeding adult has a white head and neck. The pink skin around the eyes becomes dull and gray in the nonbreeding season. It lacks any red hue, and the pouch is strongly olivaceous ochre-tinged and the legs are olivaceous gray to blackish-gray.

Double-crested cormorant species of bird

The double-crested cormorant is a member of the cormorant family of seabirds. Its habitat is near rivers and lakes as well as in coastal areas, and is widely distributed across North America, from the Aleutian Islands in Alaska down to Florida and Mexico. Measuring 70–90 cm (28–35 in) in length, it is an all-black bird which gains a small double crest of black and white feathers in breeding season. It has a bare patch of orange-yellow facial skin. Five subspecies are recognized. It mainly eats fish and hunts by swimming and diving. Its feathers, like those of all cormorants, are not waterproof and it must spend time drying them out after spending time in the water. Once threatened by the use of DDT, the numbers of this bird have increased markedly in recent years.
