The Dalmatian pelican (Pelecanus crispus), also known as the curly-headed pelican, is the largest member of the pelican family and among the heaviest flying birds in the world. With a wingspan typically ranging between , it ranks among the largest soaring birds. These pelicans are known for their graceful flight and often travel in synchronised flocks. With a range spanning across much of Central Eurasia, from the eastern Mediterranean in the west to the Taiwan Strait in the east, and from the Persian Gulf in the south to Siberia in the north, it is a short-to-medium-distance migrant between breeding and overwintering areas.
As with other pelicans, its diet is mainly fish, and the males are larger than the females. Its curly nape feathers, grey legs and silvery-white plumage are distinguishing features, and the wings appear solid grey in flight. The adults acquire a drabber plumage in winter, however, making them look more similar to the great white pelican. Its harsh vocalizations become more pronounced during the mating season. It breeds across the Palearctic from southeastern Europe to Russia, India and China in swamps and shallow lakes. It usually returns to traditional breeding sites, where it is less social than other pelican species. Its nests are crude heaps of vegetation, which are placed on islands or dense mats of vegetation.
The species' numbers dramatically declined during the 20th century, partly due to land use, disturbance and poaching activities. The core population survives in Russia, but in its Mongolian range, it is critically endangered. Removal of power lines to prevent bird strike or electrocution and constructing nesting platforms or rafts have reversed declines locally.
Taxonomy and evolution
Original description In 1832, Carl Friedrich Bruch described the Dalmatian Pelican (Pelecanus crispus), naming it the "Curly-headed Pelican" (with crispus meaning "curly" in Latin) and referring to it in German as "Krausköpfiger Pelekan". He based his description on two wild-shot specimens: an adult female from Dalmatia and a likely younger bird from Cairo. Bruch distinguished the species from P. onocrotalus by its fully feathered head, shorter webbing, and silkier plumage, noting that the curly crest appears in both juveniles and adults.
The first known illustration of the species was of the individual shot in Cairo and was created by the German naturalist and artist Heinrich von Kittlitz. However, this illustration is not currently accessible to the public. A second and more widely known illustration appeared as a plate in The Birds of Europe by John Gould. Remarkably, this artwork was produced by Edward Lear, a renowned 19th-century artist and poet best known for his nonsense literature.
Relationship with the spot-billed pelican P. phillipensis
During the 20th century, some authors suggested that the Dalmatian pelican could be a northern subspecies of the spot-billed pelican (Pelecanus philippensis), based on supposed minor morphological similarities. However, this view appeared in only a few publications and has not been widely accepted by the scientific community.
Several lines of evidence support the recognition of P. crispus and P. philippensis as distinct species. First, their breeding ranges do not overlap: P. crispus is found across southeastern Europe and Central Asia, while P. philippensis is restricted to South and Southeast Asia. They also differ markedly in nesting behaviour; P. crispus nests on the ground, while P. philippensis nests colonially in trees, a relatively rare strategy among pelicans. Furthermore, the two species exhibit differences in sexually selected traits: P. crispus develops a bright red gular pouch during the breeding season, whereas P. philippensis retains a pale pouch year-round and displays distinctive dark spots on the bill, which are absent in P. crispus and likely function in mate signalling.
Evidence of behavioural reproductive isolation also comes from a captive mixed-species colony at the Berlin Zoo, where P. crispus and P. philippensis were housed together but did not interbreed, despite the presence of hybrid pairings among other pelican species. Finally, a 2013 molecular phylogenetic analysis based on mitochondrial and nuclear DNA confirmed that P. crispus and P. philippensis represent distinct evolutionary lineages. The divergence between the two species has been estimated at 0.7 million years ago, during the Chibanian (Middle Pleistocene).
Proposed extinct subspecies In 1941, Soviet ornithologist P.V. Serebrovsky proposed the existence of an extinct fossil subspecies of the Dalmatian pelican, Pelecanus crispus palaeocrispus, based on Pleistocene remains found at the Binagadi tar pits in present-day Azerbaijan. Nonetheless, the subspecies is not formally accepted by international taxonomic authorities.
Description
The Dalmatian pelican is the largest of all pelican species and one of the heaviest flying birds in the world, with a body length of , a wingspan typically ranging between ., and an average weight of about .
The species is most easily recognised by its enormous bill, which typically measures between long and includes a large pouch used for catching fish. This makes it the bird species with the second longest bill, only surpassed by the Australian pelican (Pelecanus conspicillatus), whose bill length ranges from . During the breeding season, this pouch becomes a vivid orange-red, contrasting with the more subdued yellow or grey tones observed during the rest of the year. The upper mandible remains greyish throughout, often with a slight orange tip.
The Dalmatian pelican has silvery-white plumage, which may appear more grey or creamy, especially in winter.Dalmatian pelican videos, photos and facts – Pelecanus crispus . ARKive. Retrieved on 2012-08-22. A distinguishing feature is the presence of a shaggy crest of curly feathers on the nape and back of the head, giving the bird a notably unkempt appearance compared to the smooth-headed great white pelican (Pelecanus onocrotalus).del Hoyo, et al., Handbook of the Birds of the World. Volume 1: Ostrich to Ducks. Lynx Edicons (1992), The legs are dark grey, another feature that helps separate it from related species with pinkish legs.
While generally a quiet species, the Dalmatian pelican may produce deep, guttural grunts, hisses, or barking sounds during the breeding season. Juveniles are overall greyer and duller in appearance, with less distinctive crests and darker plumage, but gradually acquire the characteristic silvery-white plumage as they mature.
Distribution and habitat Historically, the Dalmatian pelican was far more widespread across Europe than it is today. Subfossil remains dating back to the Holocene climatic optimum, approximately 7400 to 5000 years BP have been found as far north as Denmark. Additional remains dated to 1900–600 BP have been uncovered in central Europe, the Netherlands, and Great Britain. These finds suggest that the species once ranged across much of the continent during periods of warmer climate.Currently, the Dalmatian pelican is widely distributed across southeastern Europe, Central Asia, and the Indian subcontinent, inhabiting large, open wetlands such as lakes, rivers, deltas, estuaries, and floodplains. Unlike the great white pelican, which remains mostly in lowlands, the Dalmatian pelican nests at various elevations and is more philopatric, typically returning to the same traditional breeding sites unless they become unsuitable due to disturbance or degradation. During the non-breeding season, the Dalmatian pelican seeks out ice-free inland waters, such as large lakes in Europe or temporary wetlands known as jheels in India, which provide essential foraging and resting habitat. As global temperatures rise and such habitats become more widely available or persist longer into the year, there is growing evidence that the species is gradually expanding its range, responding to increasingly favorable environmental conditions.
Current populations and breeding sites The global population of the Dalmatian pelican is estimated at between 10,000 and 20,000 individuals, with roughly 3,000 to 5,000 breeding pairs.Dalmatian Pelican (Pelecanus crispus) – BirdLife species factsheet. Birdlife.org (1998-10-03). Retrieved on 2012-08-22. Although the species suffered dramatic declines during the 20th century, several strongholds remain. The largest known breeding colony is found at Small Prespa Lake, which is shared between Greece and Albania and supports around 1,600 pairs. Another significant population persists in the Danube Delta, with approximately 450 pairs recorded there.
Russia now hosts the largest breeding population of the Dalmatian pelican, with estimates exceeding 3,000 pairs, representing about 70% of all breeding individuals worldwide. In the southern Tyumen region of Russia, the only known breeding site is Lake Tenis, where Dalmatian pelicans nest on reed islets. Other active breeding sites are scattered across southeastern Europe, including regions in Ukraine, North Macedonia, Romania, Bulgaria—particularly the Srebarna Nature Reserve—and Albania, where Karavasta Lagoon serves as a key nesting site. Although the species was considered extinct in Croatia since the 1950s, a lone Dalmatian pelican was observed there in 2011.
Movements
The Dalmatian pelican is a partial migrant, and its movement patterns vary significantly across its range. In Europe, many populations are dispersive rather than fully migratory, with individuals often remaining near their breeding sites year-round or making only short-distance movements to the Mediterranean basin in winter. For example, in the Danube Delta, birds typically arrive in March and leave by the end of August, reflecting a predictable seasonal pattern aligned with breeding and food availability.
By contrast, populations in Asia undertake more substantial migration. Pelicans breeding in southern Russia generally migrate to the central Middle East for the winter, with many wintering in wetlands across Iran and extending through the Indian subcontinent, reaching as far south as Sri Lanka and westward into Nepal and central India. Mongolian-breeding birds follow a different route, traveling to the east coast of China, including areas around Hong Kong, to spend the winter months.
In flight, the Dalmatian pelican is striking: it soars with slow, powerful wingbeats, neck pulled back in a characteristic "S" shape similar to a heron. The wings are broad and pale greyish-white, with noticeable black tips on the primaries. This bird often flies in synchronized groups, gliding gracefully and silently above lakes and wetlands.
Takeoff from water is particularly energetic. The pelican requires strong pushes with both feet and heavy flapping of its broad wings to become airborne, especially when carrying a full pouch of fish.
Feeding ecology
The Dalmatian pelican is a piscivorous, non-apex predator, functionally classified as an opportunistic secondary-to-tertiary consumer. It forages across freshwater, brackish, and coastal ecosystems, primarily during crepuscular hours, using shallow-water surface capture techniques. Its trophic role positions it as a top-level vertebrate consumer, but below strict apex predators due to its limited prey diversity and lack of intra-guild predation.
Diet composition They predominantly consume fish from freshwater, brackish, and marine environments. Most of these are small to medium-sized fish; large enough to justify the effort of capture but small enough to be swallowed whole, as pelicans do not tear or chew their prey.
