Dalmatian Pelican/Pelecanus crispus - Adult


No subspecies are known to exist over its wide range, but based on size differences, a Pleistocene paleosubspecies, Pelecanus crispus palaeocrispus, has been described from fossils recovered at Binagady, Azerbaijan.


This huge bird is the largest of the pelicans and one of the largest living bird species. It measures 160 to 183 cm (5 ft 3 in to 6 ft 0 in) in length, 9–15 kg (20–33 lb) in weight and 290–351 cm (9 ft 6 in–11 ft 6 in) in wingspan. Its mean weight of around 11.5 kg (25 lb) makes it the world's heaviest flying bird species, although the largest individuals among male bustards and swans may be heavier than the largest individual Dalmatian Pelican. It also appears to have one of the largest wingspans of any living bird, rivaling those of the great albatrosses.

The somewhat similar-looking Great White Pelican is typically slightly smaller but the largest male individuals can be essentially the same size as a typical Dalmatian. However, the Dalmatian differs from this other very large species in that it has curly nape feathers, grey legs and silvery-white (rather than pure white) plumage. In winter, adult pelicans of this species go from silvery-gray to a dingier brownish-gray cream color. Immature birds are grey and lack the pink facial patch of immature White Pelicans. The loose feathers around the forehead of the Dalmatian Pelican can form a W-like-shape on the face right above the bill. In the breeding season it has an orange-red lower mandible and pouch against a yellow upper mandible. In winter, the whole bill is a somewhat dull yellow. The bill, at 36 to 45 cm (14 to 18 in) long, is the second largest of any bird, after the Australian Pelican. The bare skin around the eye can vary from yellow to purplish in color. Among standard measurements, compared to the Great White Pelican, the Dalmatian's tarsus is slightly shorter, at 11.6 to 12.2 cm (4.6 to 4.8 in), but its tail and wing chord length are notably larger, at 22 to 24 cm (8.7 to 9.4 in) long and 68 to 80 cm (27 to 31 in), respectively. When the Dalmatian Pelican is in flight, unlike other pelicans, its wings are solid grayish-white with black tips. It is an elegant soaring bird. When a whole flock of Dalmatian Pelicans is in flight, all its members move in graceful synchrony, their necks held back like a heron's. It is the largest living creature that can fly.

The Dalmatian Pelican is often silent, as most pelicans are, although it can be fairly vocal during the mating season, when it may engage in a wide range of guttural, deep vocalisations, including barks, hisses and grunts.


The Dalmatian Pelican is found in lakes, rivers, deltas and estuaries. Compared to the Great White Pelican, the Dalmatian is not as tied to lowland areas and will nest in suitable wetlands at many elevations. It is less opportunistic in breeding habitat selection than the Great White, usually returning to a traditional breeding site year after year unless it becomes completely unsuitable. During the winter, Dalmatian Pelicans usually stay on ice-free lakes in Europe or jheels (seasonal lakes) in India. They also visit, typically during winter, inshore areas along sheletered coasts for feeding.


This pelican usually migrates short distances. It is dispersive in Europe, based on feeding opportunities, with most western birds staying through the winter in the Mediterranean region. In the Danube Delta, Dalmatian Pelicans arrive in March and leave by the end of August. It is more actively migratory in Asia, where most of the birds that breed in Russia fly down for the winter to the central Middle East, largely around Iran through to the Indian Subcontinent, from Nepal to central India. The pelicans who breed in Mongolia winter along the east coast of China, including the Hong Kong area.


This pelican feeds almost entirely on fish. Preferred prey species can include Common carp, European perch, Common rudd, eels, catfish (especially silurids during winter), mullet and Northern Pike, the latter having measured up to 50 cm (20 in) when taken. In the largest remnant colony, located in Greece, the preferred prey is reportedly the native Alburnus belvica. The Dalmatian Pelican requires around 1,200 g (2.6 lb) of fish per day and can take locally abundant smaller fish such as gobies, but usually ignore them in lieu of slightly larger fish. It usually forages alone or in groups of only twos or threes. It normally swims along, placidly and slowly, until it quickly dunks its head underwater and scoops the fish out, along with great masses of water. The water is dumped out of the sides of the pouch and the fish is swallowed. Occasionally it may feed cooperatively with other pelicans by corraling fish into shallow waters and may even cooperate similarly while fishing alongside cormorants in Greece. Occasionally, the pelican may not immediately eat the fish contained in its gular pouch, so it can save the prey for later consumption. Other small wetlands-dwellers may supplement the diet, including crustaceans, worms, beetles and small water birds, usually nestlings and eggs.


Among a highly social family in general, Dalmatian Pelicans may have the least social of inclinations. This species naturally nests in relatively small group compared to most other pelican species and sometimes may even nest alone. However, small colonies are usually formed, which regularly include upwards of 250 pairs (especially historically). Occasionally, Dalmatian Pelicans may mix in with colonies of Great White Pelicans. Nesting sites selected are usually either islands in large bodies of water (typically lagoons or river deltas) or dense mats of aquatic vegetation, such as extensive reedbeds of Phragmites and Typha. Due to their large size, these pelicans often trample the vegetation in the area surrounding their nests into the muddy substrate and thus nesting sites may become unsuitably muddy after around three years of usage.

The nest is a moderately-sized pile of grass, reeds, sticks and feathers, usually measuring about 1 m (3.3 ft) deep and 63 cm (25 in) across. Nests are usually located on or near the ground, often being placed on dense floating vegetation. Nests tend to be flimsy until cemented together by droppings. Breeding commences in March or April, about a month before the Great White Pelican breeds. The Dalmatian Pelican lays a clutch of 1 to 6 eggs, with two eggs being the norm. Eggs weigh between 120 and 195 g (4.2 and 6.9 oz). Incubation, which is spilt between both parents, lasts for 30 to 34 days. The chicks are born naked but soon sprout white down feathers. When the young are 6 to 7 weeks of age, the pelicans frequently gather in "pods". The offspring fledge at around 85 days and become independent at 100 to 105 days old. Nesting success relies on local environmental conditions, with any where from 58% to 100% of hatchlings successfully surviving to adulthood. The nesting sites often insure limited nest predation, though carnivorous mammals who eat egg and nestling can access nests when water levels are low enough for them to cross, as has been recorded with wild boars destroying nests in Bulgaria. Jackals, foxes, wolves, dogs and lynxes are also regular nest predators when water levels are low and White-tailed Eagles may attack pelicans at the colony to at least the size of fledgings. Sexual maturity is thought to be obtained at 3 or 4 years of age.


This species of pelican has declined greatly throughout its range, more so than the White Pelican. It is possible that up to 10,000–20,000 pelicans exist at the species level. Reportedly, there were once millions of Dalmatian Pelicans in Romania alone. During the 20th century, the species' numbers underwent a dramatic decline for reasons that are not entirely understood. The most likely reason was habitat loss due to human activities such as the drainage of wetlands and land development. Colonies are regularly disturbed by human activity, and, like all pelicans, the parents may temporarily leave their nest if threatened, which then exposes the chicks to the risk of predation. Occasionally, Dalmatian Pelicans may be shot by fishermen who believe the birds are dangerously depleting the fish population and hence threatening their livelihood. While such killings are generally on a small scale, the worry that these pelicans over-exploit the fishing stock persists in many locales. Another probable reason for the decline in the species' population is poaching. In Mongolia, the local people clandestinely kill these pelicans to use or sell their bills as pouches.On a typical day in a commercial Mongolian marketplace, as many as fifty pelican bills may be on offer for sale, and they are considered such a rare prize that ten horses and thirty sheep are considered a fair price to trade for a single pelican. Due to exploitation at all stages of the life cycle, the species is critically endangered in its Mongolian range, with a total population of fewer than 130 individual birds. Dalmatian Pelicans also regularly fly into power-lines and are killed by electrocution. In Greece, pelicans are often so disturbed by power boats, usually ones bearing tourists--that they become unable to feed and die of malnourishment.. As of 1994, in Europe there are over a thousand breeding pairs, most of them in Greece, but also in Ukraine, Macedonia, Romania, Bulgaria and Albania (Karavasta Lagoon). They have been considered extinct in Croatia sinces the 1950s, although a single Dalmatian Pelican was observed there in 2011. The largest single remaining colony is at Lake Mikri in Greece, with around 1,400 pairs, with approximately 450 pairs left in the Danube Delta. The country with the largest breeding population today, including about 70% of pairs or possibly over 3,000 pairs, is Russia. Worldwide, there are an estimated 3,000–5,000 breeding pairs. One report of approximately 8,000 Dalmatian Pelicans in India turned out to be a congregation of misidentified Great White Pelicans.

The Dalmatian Pelican is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies. Conservationist efforts have been undertaken on behalf of the species, especially in Europe. Although they normally nest on the ground, Dalmatian Pelicans have nested on platforms put out in Turkey, Greece, Bulgaria and Romania in order to encourage them to breed. Rafts over water have also been set up for the species to use in Greece and Bulgaria. Power-lines have also been marked or dismantled in areas adjacent to colonies in these countries. Additionally, water-level management and educational programs may be aiding them at a local level. Although efforts have been undertaken in Asia, there is a much higher rate of poaching, shooting and habitat destruction there, which may make conservation efforts more difficult. In 2012, when unusually frigid winter conditions caused the Caspian Sea to freeze over, it resulted in the death from starvation of at least twenty of the Dalmatian Pelicans that overwinter there. Despite local authorities' initial attempts to discourage it, many people there turned out with fish and hand-fed the birds, apparently enabling the huge pelicans to survive the winter.
